While we're here, clean up argument passing - protocol to always use simple nul-terminated strings, instead of - sometimes using offset pointers to mark the end of arguments. - This change also fixes PR/1517. - Reported by Damien GIBOU <damien.gibou@st.com>. - - * function.c (struct function_table_entry): Remove the negative - required_args hack; put in explicit min and max # of arguments. - (function_table): Add in the max value.

We don't try to be fancy and - pass one style of arguments to expanded functions and another - style to non-expanded functions: pass pointers to nul-terminated - strings to all functions. - (func_call): Rewrite this. If we are invoking a builtin function - and it's supposed to have its arguments expanded, do that (since - it's not done by handle_function for $(call ...) anymore). For - non-builtins, just add the variables as before but mark them as - recursive so they'll be expanded later, as needed. - (func_if): All arguments are vanilla nul-terminated strings: - remove trickery with "argv[1]-1". - (func_foreach): Ditto. - - * expand.c (expand_argument): If the second arg is NULL, expand - the entire first argument. - - * job.c (new_job): Zero the child struct.

Smith <psmith@gnu.org> - - * main.c (quote_for_env): Rename from quote_as_word(). - - * make.h, *.c: Prefer strchr() and strrchr() in the code - rather than index() and rindex().

Smith <psmith@gnu.org> - - * Version 3.78 released. - - * main.c (main): Only fail on multiple --jobserver-fds options if - they aren't all the same.

Smith <psmith@gnu.org> - - * main.c (print_version): Ugh. GLIBC's configure tries to check - make version strings and is too aggressive with their matching - expressions. I've struck a deal with them to leave the version - output as-is for 3.78, and they'll change their configure checks - so that I can change this back in the future. - -1999-09-07 Eli Zaretskii <eliz@is.elta.co.il> - - * job.c (construct_command_argv_internal) [__MSDOS__]: Add "echo" - and "unset" to the list of builtin shell commands. - - * configh.DOS.template (MAKE_HOST): Define to "i386-pc-msdosdjgpp" - which is the canonical name of the DJGPP host. - -1999-09-05 Paul D.

Smith <psmith@gnu.org> - - * remake.c (notice_finished_file): Always set mtime_before_update - if it's not been set, not just if we ran some rules. Otherwise we - may have a situation where a target's prerequisite was rebuilt but - not changed, so this target's rules weren't run, then - update_goal_chain() sees mtime_before_update != last_mtime and - thinks that the top-level target changed when it really didn't. - This can cause an infinite loop when remaking makefiles. - (update_goal_chain): If we get back to the top and we don't know - what the goal's last_mtime was, find it now. We need to know so - we can compare it to mtime_before_update later (this is only - crucial when remaking makefiles--should we only do it then?) - -1999-09-02 Paul D. Smith <psmith@gnu.org> - - * read.c (read_makefile): If "override" appears as the first - prerequisite, look further to ensure this is really a - target-specific variable definition, and not just some - prerequisite named "override". - -1999-09-01 Paul D. Smith <psmith@gnu.org> - - * function.c (IS_PATHSEP) [WINDOWS32]: Allow backslash separators - for W32 platforms. - * read.c (record_files) [WINDOWS32]: Allow backslash separators - for W32 platforms. - * implicit.c (pattern_search) [WINDOWS32]: Allow backslash - separators for W32 platforms. - - * configure.in (MAKE_HOST): Define it to be the canonical build - host info, now that we need AC_CANONICAL_HOST anyway (for large - file support). - * version.c (make_host): Define a variable to MAKE_HOST so we're - sure to get it from the local config.h. - * main.c (print_version): Use it in the version information. - * config.ami.template: Add MAKE_HOST. - * configh.dos.template: Ditto. - * config.h.W32.template: Ditto. - * config.h-vms.template: Ditto. - - * main.c (main): Close the jobserver file descriptors if we need - to re-exec ourselves. - Also print more reasonable error if users force -jN for submakes. - This may be common for a while until people use the jobserver - feature. If it happens, we ignore the existing jobserver stuff - and use whatever they specified on the commandline. - (define_makeflags): Fixed a long-standing bug: if a long name - only option comes immediately after a single letter option with no - argument, then the option string is constructed incorrectly. For - example, with -w and --jobserver-fds you get "-w-jobserver-fds..." - instead of "-w --jobserver-fds..."; add in an extra " -". - - * make.texinfo (Phony Targets): Add another example of using - .PHONY with subdirectories/recursive make. - -1999-08-30 Paul D. Smith <psmith@gnu.org> - - * README.W32.template: Renamed from README.W32 so it's - autogenerated during the dist. A few minor modifications. - - * configure.in: Check for kstat_open before AC_FUNC_GETLOADAVG - since the latter needs to know whether the former exists to give - an accurate result. - -1999-08-26 Rob Tulloh <rob_tulloh@dev.tivoli.com> - - * NMakefile [WINDOWS32]: Now more robust. If you change a file - under w32/subproc, the make.exe will be relinked. Also added some - tests to make sure erase commands won't fail when executed in a - pristine build environment. - - * w32/subproc/sub_proc.c [WINDOWS32]: Added support for - HAVE_CYGWIN_SHELL. If you are using the Cygwin B20.1 release, it - is now possible to have have native support for this shell without - having to rely on klutzy BATCH_MODE_ONLY_SHELL. - - * config.h.W32 [WINDOWS32]: Added HAVE_CYGWIN_SHELL macro which - users can define if they want to build make to use this shell. - - * README.W32 [WINDOWS32]: Added informaton about - HAVE_CYGWIN_SHELL. Cleaned up text a bit to make it more current. - -1999-08-26 Paul Eggert <eggert@twinsun.com> - - Support large files in AIX, HP-UX, and IRIX. - - * acinclude.m4 (AC_LFS): Remove. Superseded by AC_SYS_LARGEFILE. - (AC_SYS_LARGEFILE_FLAGS, AC_SYS_LARGEFILE_SPACE_APPEND, - AC_SYS_LARGEFILE_MACRO_VALUE, AC_SYS_LARGEFILE): New macros. - (jm_AC_TYPE_UINTMAX_T): Check for busted compilers that can't - shift or divide unsigned long long. - (AM_PROG_CC_STDC): New macro; a temporary workaround of a bug in - automake 1.4. - - * configure.in (AC_CANONICAL_HOST): Add; required by new - AC_SYS_LARGEFILE. - (AC_SYS_LARGEFILE): Renamed from AC_LFS. - (AM_PROG_CC_STDC): Add. - - * config.guess, config.sub: New files, needed for AC_CANONICAL_HOST. - -1999-08-25 Paul Eggert <eggert@twinsun.com> - - * make.h (CHAR_MAX): New macro. - * main.c (struct command_switch): c is now int, - so that it can store values greater than CHAR_MAX. - (switches): Replace small numbers N with CHAR_MAX+N-1, - to avoid problems with non-ASCII character sets. - (short_option): New macro. - (init_switches, print_usage, define_makeflags): Use it instead of - isalnum. - -1999-08-25 Paul D. Smith <psmith@gnu.org> - - * Version 3.77.94 released. - - * main.c (main) [__MSDOS__]: If the user uses -j, warn that it's - not supported and reset it. - - * make.h (ISDIGIT): Obtained this from the textutils distribution. - * main.c (decode_switches): Use it. - * function.c (is_numeric): Use it. - - * main.c (struct command_switch): Store the switch char in an - unsigned char to shut up GCC about using it with ctype.h macros. - Besides, it _is_ always unsigned. - -1999-08-24 Paul D. Smith <psmith@gnu.org> - - * make.texinfo: Change "dependency" to "prerequisite" and - "dependencies" to "prerequisites". Various other cleanups related - to the terminology change. - * file.c: Change debugging and error messages to use - "prerequisite" instead of "dependency". - * implicit.c: Ditto. - * remake.c: Ditto. - * NEWS: Document it. - -1999-08-23 Paul D. Smith <psmith@gnu.org> - - * remake.c (update_file): Move the considered check into the - double-colon rule loop, so we consider double-colon rules - individually (otherwise after the first is pruned, the rest won't - get run). - - * README.template: Minor changes. - - Remove the debugging features of the jobserver, so it no longer - writes distinct tokens to the pipe. Thus, we don't need to store - the token we get. A side effect of this is to remove a potential - "unavailable token" situation: make-1 invokes make-2 with its - special token and make-3 with a normal token; make-2 completes. - Now we're waiting for make-3 but using 2 tokens; our special token - is idle. In the new version we don't have special tokens per se, - we merely decide if we already have a child or not. If we don't, - we don't need a token. If we do, we have to get one to run the - next child. Similar for putting tokens back: if we're cleaning up - the last child, we don't put a token back. Otherwise, we do. - - * main.c: Add a new, internal flag --jobserver-fds instead of - overloading the meaning of -j. Remove job_slots_str and add the - stringlist jobserver_fds. - (struct command_switch): We don't need the int_string type. - (switches[]): Add a new option for --jobserver-fds and remove - conditions around -j. Make the description for the former 0 so it - doesn't print during "make --help". - (main): Rework jobserver parsing. If we got --jobserver-fds - make sure it's valid.

Always call - free_child, even if we're dying. - (free_child): If we're not freeing the only child, put a token - back in the pipe. Then, if we're dying, don't bother to free. - (new_job): If we are using the jobserver, loop checking to see if - a) there are no children or b) we get a token from the pipe. - - * job.h (struct child): Remove the job_token field. - -1999-08-20 Paul D. Smith <psmith@gnu.org> - - * variable.c (try_variable_definition): Allocate for variable - expansion in f_append with a simple variable: if we're looking at - target-specific variables we don't want to trash the buffer. - Noticed by Reiner Beninga <Reiner.Beninga@mchp.siemens.de>. - -1999-08-16 Eli Zaretskii <eliz@is.elta.co.il> - - * main.c (main) [__MSDOS__]: Mirror any backslashes in argv[0], to - avoid problems in shell commands that use backslashes as escape - characters. - -1999-08-16 Paul D.

Smith <psmith@gnu.org> - - Another jobserver algorithm change. We conveniently forgot that - the blocking bit is shared by all users of the pipe, it's not a - per-process setting. Since we have many make processes all - sharing the pipe we can't use the blocking bit as a signal handler - flag. Instead, we'll dup the pipe's read FD and have the SIGCHLD - handler close the dup'd FD. This will cause the read() to fail - with EBADF the next time we invoke it, so we know we need to reap - children. We then re-dup and reap. - - * main.c (main): Define the job_rfd variable to hold the dup'd FD. - Actually dup the read side of the pipe. Don't bother setting the - blocking bit on the file descriptor. - * make.h: Declare the job_rfd variable. - * job.c (child_handler): If the dup'd jobserver pipe is open, - close it and assign -1 to job_rfd to notify the main program that - we got a SIGCHLD. - (start_job_command): Close the dup'd FD before exec'ing children. - Since we open and close this thing so often it doesn't seem - worth it to use the close-on-exec bit. - (new_job): Remove code for testing/setting the blocking bit. - Instead of EAGAIN, test for EBADF. If the dup'd FD has been - closed, re-dup it before we reap children. - - * function.c (func_shell): Be a little more accurate about the - length of the error string to allocate. - - * expand.c (variable_expand_for_file): If there's no filenm info - (say, from a builtin command) then reset reading_file to 0. - -1999-08-09 Paul D.

Smith <psmith@gnu.org> - - New jobserver algorithm to avoid a possible hole where we could - miss SIGCHLDs and get into a deadlock. The original algorithm was - suggested by Roland McGrath with a nice refinement by Paul Eggert. - Many thanks as well to Tim Magill and Howard Chu, who also - provided many viable ideas and critiques. We all had a fun week - dreaming up interesting ways to use and abuse UNIX syscalls :). - - Previously we could miss a SIGCHLD if it happened after we reaped - the children but before we re-entered the blocking read. If this - happened to all makes and/or all children, make would never wake - up. - - We avoid this by having the SIGCHLD handler reset the blocking bit - on the jobserver pipe read FD (normally read does block in this - algorithm). Now if the handler is called between the time we reap - and the time we read(), and there are no tokens available, the - read will merely return with EAGAIN instead of blocking. - - * main.c (main): Set the blocking bit explicitly here. - * job.c (child_handler): If we have a jobserver pipe, set the - non-blocking bit for it. - (start_waiting_job): Move the token stuff back to new_job; if we - do it here then we're not controlling the number of remote jobs - started! - (new_job): Move the check for job slots to _after_ we've created a - child structure. If the read returns without getting a token, set - the blocking bit then try to reap_children. - - * make.h (EINTR_SET): Define to test errno if EINTR is available, - or 0 otherwise. Just some code cleanup. - * arscan.c (ar_member_touch): Use it. - * function.c (func_shell): Use it. - * job.c (reap_children): Use it. - * remake.c (touch_file): Use it. - -1999-07-28 Paul D.

Smith <psmith@gnu.org> - - * Version 3.77.91 released. - - * configure.in: Changes to the boostrapping code: if build.sh.in - doesn't exist configure spits an error and generates an empty - build.sh file which causes make to be confused. - * maintMakefile: Don't build README early. - -1999-07-23 Paul D. Smith <psmith@gnu.org> - - * job.c (my_job_token): This variable controls whether we've - handed our personal token to a subprocess or not. Note we could - probably infer this from the value of job_slots_used, but it's - clearer to just keep it separately. Job_slots_used isn't really - relevant when running the job server. - (free_job_token): New function: free a job token. If we don't - have one, no-op. If we have the personal token, reclaim it. If - we have another token, write it back to the pipe. - (reap_children): Call free_job_token. - (free_child): Call free_job_token. - (start_job_command): Remove duplicate test for '+' in the command. - If we don't appear to be running a recursive make, close the - jobserver filedescriptors. - (start_waiting_job): If our personal token is available, use that - instead of going to the server pipe. - (*): Add the token value to many debugging statements, and print - the child target name in addition to the ptr hex value. - Change the default "no token" value from '\0' to '-' so it looks - better in the output. - - * main.c (main): Install the child_handler with sigaction() - instead of signal() if we have it. On SysV systems, signal() uses - SysV semantics which are a pain. But sigaction() always does what - we want. - (main): If we got job server FDs from the environment, test them - to see if they're open. If not, the parent make closed them - because it didn't think we were a submake. Print a warning and - suggestion to use "+" on the submake invocation, and hard-set to - -j1 for this instance of make. - (main): Change the algorithm for assigning slots to be more - robust. Previously make checked to see if it thought a subprocess - was a submake and if so, didn't give it a token. Since make's - don't consume tokens we could spawn many of makes fighting for a - small number of tokens. Plus this is unreliable because submakes - might not be recognized by the parent (see above) then all the - tokens could be used up by unrecognized makes, and no one could - run. Now every make consumes a token from its parent. However, - the make can also use this token to spawn a child. If the make - wants more than one, it goes to the jobserver pipe. Thus there - will never be more than N makes running for -jN, and N*2 processes - (N makes and their N children). Every make can always run at - least one job, and we'll never deadlock. (Note the closing of the - pipe for non-submakes also solves this, but this is still a better - algorithm.) So! Only put N-1 tokens into the pipe, since the - topmost make keeps one for itself. - - * configure.in: Find sigaction. Disable job server support unless - the system provides it, in addition to either waitpid() or - wait3(). - -1999-07-22 Rob Tulloh <rob_tulloh@dev.tivoli.com> - - * arscan.c (ar_member_touch) [WINDOWS32]: The ar_date field is a - string on Windows, not a timestamp. - -1999-07-21 Paul D. Smith <psmith@gnu.org> - - * Version 3.77.90 released. - - * Makefile.am (AUTOMAKE_OPTIONS): Require automake 1.4. - - * function.c: Rearrange so we don't need to predeclare the - function_table array; K&R C compilers don't like that. - - * acinclude.m4 (AC_FUNC_SELECT): Ouch; this requires an ANSI C - compiler! Change to work with K&R compilers as well. - - * configure.in (AC_OUTPUT): Put build.sh back. I don't know how I - thought it would work this way :-/. We'll have to think of - something else. - * Makefile.am: Remove rule to create build.sh. - - * default.c (default_suffix_rules): Rearrange the default command - lines to conform to POSIX rules (put the filename argument $< - _after_ the OUTPUT_OPTION, not before it). - - * various: Changed !strncmp() calls to strneq() macros. - - * misc.c (sindex): Make slightly more efficient. - - * dir.c (file_impossible): Change savestring(X,strlen(X)) to xstrdup(). - * implicit.c (pattern_search): Ditto. - * main.c (enter_command_line_file): Ditto. - (main): Ditto. - * misc.c (copy_dep_chain): Ditto. - * read.c (read_makefile): Ditto. - (parse_file_seq): Ditto. - (tilde_expand): Ditto. - (multi_glob): Ditto. - * rule.c (install_pattern_rule): Ditto. - * variable.c (define_variable_in_set): Ditto. - (define_automatic_variables): Ditto. - * vpath.c (construct_vpath_list): Ditto. - - * misc.c (xrealloc): Some reallocs are non-standard: work around - them in xrealloc by calling malloc if PTR is NULL. - * main.c (main): Call xrealloc() directly instead of testing for - NULL. - - * function.c (func_sort): Don't try to free NULL; some older, - non-standard versions of free() don't like it. - - * configure.in (--enable-dmalloc): Install some support for using - dmalloc (http://www.dmalloc.com/) with make. Use --enable-dmalloc - with configure to enable it. - - * function.c (function_table_entry): Whoops! The function.c - rewrite breaks backward compatibility: all text to a function is - broken into arguments, and extras are ignored. So $(sort a,b,c) - returns "a"! Etc. Ouch. Fix it by making a positive value in - the REQUIRED_ARGS field mean exactly that many arguments to the - function; any "extras" are considered part of the last argument as - before. A negative value means at least that many, but may be - more: in this case all text is broken on commas. - (handle_function): Stop when we've seen REQUIRED_ARGS args, if >0. - (expand_builtin_function): Compare number of args to the absolute - value of REQUIRED_ARGS. - -1999-07-20 Paul D. Smith <psmith@gnu.org> - - * job.c (start_job_command): Ensure that the state of the target - is cs_running. It might not be if we skipped all the lines due to - -n (for example). - - * commands.c (execute_file_commands): If we discover that the - command script is empty and succeed early, set cs_running so the - modtime of the target is still rechecked. - - * rule.c (freerule): Free the dependency list for the rule. - - * implicit.c (pattern_search): When turning an intermediate file - into a real target, keep the also_make list. - Free the dep->name if we didn't use it during enter_file(). - -1999-07-16 Paul D. Smith <psmith@gnu.org> - - * read.c (read_makefile): Don't allocate the commands buffer until - we're sure we found a makefile and won't return early (mem leak). - - * job.c (start_job_command): Broken #ifdef test: look for F_SETFD, - not FD_SETFD. Close-on-exec isn't getting set on the bad_stdin - file descriptor and it's leaking :-/. - * getloadavg.c (getloadavg): Ditto. - -1999-07-15 Paul D.

Smith <psmith@gnu.org> - - * job.c (start_waiting_job): Don't get a second job token if we - already have one; if we're waiting on the load to go down - start_waiting_job() might get called twice on the same file. - - * filedef.h (struct file): Add new field, mtime_before_update. - When notice_finished_file runs it assigns the cached last_mtime to - this field. - * remake.c (update_goal_chain): Notice that a file wasn't updated - by asking if it changed (g->changed) and comparing the current - cached time (last_mtime) with the previous one, stored in - mtime_before_update. The previous check ("did last_mtime changed - during the run of update_file?") fails for parallel builds because - last_mtime is set during reap_children, before update_file is run. - This causes update_goal_chain to always return -1 (nothing - rebuilt) when running parallel (-jN). This is OK during "normal" - builds since our caller (main) treats these cases identically in - that case, but if when rebuilding makefiles the difference is very - important, as it controls whether we re-exec or not. - * file.c (file_hash_enter): Copy the mtime_before_update field. - (snap_deps): Initialize mtime_before_update to -1. - * main.c (main): Initialize mtime_before_update on old (-o) and - new (-W) files. - -1999-07-08 Paul D. Smith <psmith@gnu.org> - - * main.c (switches): Define a new switch -R (or - --no-builtin-variables).

Smith <psmith@gnu.org> - - * read.c (read_makefile): Cast -1 arguments to - variable_expand_string() to long. Alexandre Sauve - <Alexandre.SAUVE@ifp.fr> reports that without casts, this breaks - on a NEC SUPER-UX SX-4 system (and it's wrong without a cast - anyway). Of course, (a) I'd really love to start using function - prototypes, and (b) there's a whole slew of issues related to int - vs. long and signed vs. unsigned in the length handling of - variable buffers, etc. Gross.

If it works well this will go - away. - - * NEWS: Summarize the new feature. - - * acconfig.h: New definition MAKE_JOBSERVER if job server support - is enabled. - * config.h-vms.template: Undef MAKE_JOBSERVER for this port. - * config.h.W32.template: Ditto. - * config.ami.template: Ditto. - - * main.c (struct command_switch): Add a new type: int_string. - (switches[]) Use int_string for -j if MAKE_JOBSERVER. - (init_switches): Initialize the new int_string switch type. - (print_usage): New function, extracted from decode_switches(). - (decode_switches): Call it. Decode the new int_string switch type. - (define_makeflags): Add new int_string switch data to MAKEFLAGS. - (job_fds[]) Array to contain the pipe file descriptors. - (main): Parse the job_slots_str option results. If necessary, - create the pipe and seed it with tokens. Set the non-blocking bit - for the read fd. Enable the signal handler for SIGCHLD even if we - have a non-hanging wait; it's needed to interrupt the select() in - job.c:start_waiting_job(). - - * make.h: Declare job_fds[]. - - * job.h (struct child): Add job_token field to store the token for - this job (if any). - - * job.c (reap_children): When a child is fully reaped, release the - token back into the pipe. - (free_child): If the child to be freed still has a token, put it - back. - (new_job): Initialize the job_token member. - (start_waiting_job): For local jobs, if we're using the pipe, get - a token before we check the load, etc. We do this by performing a - non-blocking read in a loop. If the read fails, no token is - available. Do a select on the fd to wait for a token. We need to - re-enable the signal handler for SIGCHLD even if we have a - non-hanging waitpid() or wait3(), so that the signal will - interrupt the select() and we can wake up to reap children. - (child_handler): Re-enable the signal handler. The count is still - kept although it's not needed or used unless you don't have - waitpid() or wait3(). - -1999-04-10 Paul D. Smith <psmith@gnu.org> - - * main.c (main): Reset the considered bit on all the makefiles if - something failed to update; we need to examine them again if they - appear as normal targets in order to get the proper error message. - -1999-04-09 Paul D. Smith <psmith@gnu.org> - - Performance enhancement from Tim Magill <tim.magill@telops.gte.com>. - - * remake.c (update_file): If you have large numbers of - dependencies and you run in parallel, make can spend considerable - time each pass through the graph looking at branches it has - already seen. Since we only reap_children() when starting a pass, - not in the middle, if a branch has been seen already in that pass - nothing interesting can happen until the next pass. So, we toggle - a bit saying whether we've seen this target in this pass or not. - (update_goal_chain): Initially set the global considered toggle to - 1, since all targets initialize their boolean to 0. At the end of - each pass, toggle the global considered variable. - * filedef.h (struct file): Per-file considered toggle bit. - * file.c: New global toggle variable considered. - -1999-04-05 Paul D. Smith <psmith@gnu.org> - - * arscan.c (ar_scan): Added support for ARFZMAG (compressed - archives?) for Digital UNIX C++. Information provided by - Patrick E. Krogel <pekrogel@mtu.edu>. - (ar_member_touch): Ditto. - -1999-04-03 Paul D. Smith <psmith@gnu.org> - - * remake.c (f_mtime): If: a) we found a file and b) we didn't - create it and c) it's not marked as an implicit target and d) it - is marked as an intermediate target, then it was so marked due to - an .INTERMEDIATE special target, but it already existed in the - directory. In this case, unset the intermediate flag so we won't - delete it when make is done. It feels like it would be cleaner to - put this check in update_file_1() but I worry it'll get missed... - -1999-04-01 Paul D. Smith <psmith@gnu.org> - - * job.c (construct_command_argv_internal): Use bcopy() to copy - overlapping strings, rather than strcpy(). ISO C says the latter - is undefined. Found this in a bug report from 1996! Ouch! - -1999-03-31 Paul D. Smith <psmith@gnu.org> - - * read.c (readline): Ignore carriage returns at the end of the - line, to allow Windows-y CRLF line terminators. - -1999-03-30 Paul D. Smith <psmith@gnu.org> - - * configure.in: Don't put build.sh here, since build.sh.in doesn't - exist initially. This cause autoreconf and automake to fail when - run on a clean CVS checkout. Instead, we create build.sh in the - Makefile (see below). - - * Makefile.am: Remove BUILT_SOURCES; this is no longer relevant. - Put those files directly into EXTRA_DIST so they're distributed. - Create a local build rule to create build.sh. - Create a local maintainer-clean rule to delete all the funky - maintainers files. - - * maintMakefile: Makefile.in depends on README, since automake - fails if it doesn't exist. Also don't remove glob/Makefile.in - here, as it causes problems. - -1999-03-26 Paul D. Smith <psmith@gnu.org> - - * configure.in: Substitute GLOBLIB if we need the link the - glob/libglob.a library. - * Makefile.am (make_LDADD): Use the subst variable GLOBLIB so we - don't link the local libglob.a at all if we don't need it. - * build.template: Don't compile glob/*.o unless we want globlib. - * maintMakefile (build.sh.in): Substitute the glob/*.o files - separately. - -1999-03-25 Paul D.

Smith <psmith@gnu.org> - - * NEWS: Mention new .LIBPATTERNS feature. - - * make.texinfo (Libraries/Search): Describe the use and - ramifications of the new .LIBPATTERNS variable. - - * remake.c (library_search): Instead of searching only for the - hardcoded expansion "libX.a" for a library reference "-lX", we - obtain a list of patterns from the .LIBPATTERNS variable and - search those in order. - - * default.c: Added a new default variable .LIBPATTERNS. The - default for UNIX is "lib%.so lib%.a". Amiga and DOS values are - also provided. - - * read.c: Remove bogus HAVE_GLOB_H references; always include - vanilla glob.h. - -1999-02-21 Paul D. Smith <psmith@gnu.org> - - * function.c (expand_function): Set value to 0 to avoid freeing it. - * variable.c (pop_variable_scope): Free the value of the variable. - (try_variable_definition): For simple variables, use - allocated_variable_expand() to avoid stomping on the variable - buffer when we still need it for other things. - - * arscan.c: Modified to support AIX 4.3 big archives. The changes - are based on information provided by Phil Adams - <padams@austin.ibm.com>. - -1999-02-19 Paul D. Smith <psmith@gnu.org> - - * configure.in: Check to see if the GNU glob library is already - installed on the system. If so, _don't_ add -I./glob to the - compile line. Using the system glob code with the local headers - is very bad mojo! - Rewrite SCCS macros to use more autoconf facilities. - - * Makefile.am: Move -Iglob out of INCLUDES; it'll get added to - CPPFLAGS by configure now. - Automake 1.4 introduced its own "include" feature which conflicts - with the maintMakefile stuff. A hack that seems to work is add a - space before the include :-/. - - * build.template: Move -Iglob out of the compile line; it'll get - added to CPPFLAGS by configure now. - -1999-02-16 Glenn D. Wolf <Glenn_Wolf@email.sps.mot.com> - - * arscan.c (ar_scan) [VMS]: Initialized VMS_member_date before - calling lbr$get_index since if the archive is empty, - VMS_get_member_info won't get called at all, and any leftover date - will be used. This bug shows up if any member of any archive is - made, followed by a dependency check on a different, empty - archive. - -1998-12-13 Martin Zinser <zinser@decus.decus.de> - - * config.h-vms [VMS]: Set _POSIX_C_SOURCE.

Smith <psmith@gnu.org> - - * job.c (start_job_command): If the command list resolves to no - chars at all (e.g.: "foo:;$(empty)") then command_ptr is NULL; - quit early. - -1998-10-12 Andreas Schwab <schwab@issan.cs.uni-dortmund.de> - - * rule.c (print_rule_data_base): Ignore num_pattern_rules if it is - zero. - -1998-10-09 Paul D. Smith <psmith@gnu.org> - - * read.c (read_makefile): Allow non-empty lines to expand to the - empty string after variable, etc., expansion, and be ignored. - -1998-09-21 Paul D. Smith <psmith@gnu.org> - - * job.c (construct_command_argv_internal): Only add COMMAND.COM - "@echo off" line for non-UNIXy shells. - -1998-09-09 Paul D. Smith <psmith@gnu.org> - - * w32/subproc/sub_proc.c: Add in missing HAVE_MKS_SHELL tests. - -1998-09-04 Paul D. Smith <psmith@gnu.org> - - * read.c (read_makefile): If we hit the "missing separator" error, - check for the common case of 8 spaces instead of a TAB and give an - extra comment to help people out. - -1998-08-29 Paul Eggert <eggert@twinsun.com> - - * configure.in (AC_STRUCT_ST_MTIM_NSEC): - Renamed from AC_STRUCT_ST_MTIM. - - * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Likewise. - Port to UnixWare 2.1.2 and pedantic Solaris 2.6. - - * acconfig.h (ST_MTIM_NSEC): - Renamed from HAVE_ST_MTIM, with a new meaning. - - * filedef.h (FILE_TIMESTAMP_FROM_S_AND_NS): - Use new ST_MTIM_NSEC macro. - -1998-08-26 Paul D. Smith <psmith@gnu.org> - - * remake.c (check_dep): For any intermediate file, not just - secondary ones, try implicit and default rules if no explicit - rules are given. I'm not sure why this was restricted to - secondary rules in the first place. - -1998-08-24 Paul D. Smith <psmith@gnu.org> - - * make.texinfo (Special Targets): Update documentation for - .INTERMEDIATE: if used with no dependencies, then it does nothing; - old docs said it marked all targets as intermediate, which it - didn't... and which would be silly :). - - * implicit.c (pattern_search): If we find a dependency in our - internal tables, make sure it's not marked intermediate before - accepting it as a found_file[]. - -1998-08-20 Paul D. Smith <psmith@gnu.org> - - * ar.c (ar_glob): Use existing alpha_compare() with qsort. - (ar_glob_alphacompare): Remove it. - - Modify Paul Eggert's patch so we don't abandon older systems: - - * configure.in: Warn the user if neither waitpid() nor wait3() is - available. - - * job.c (WAIT_NOHANG): Don't syntax error on ancient hosts. - (child_handler, dead_children): Define these if WAIT_NOHANG is not - available. - (reap_children): Only track the dead_children count if no - WAIT_NOHANG. Otherwise, it's a boolean. - - * main.c (main): Add back signal handler if no WAIT_NOHANG is - available; only use default signal handler if it is. - -1998-08-20 Paul Eggert <eggert@twinsun.com> - - Install a more robust signal handling mechanism for systems which - support it. - - * job.c (WAIT_NOHANG): Define to a syntax error if our host - is truly ancient; this should never happen. - (child_handler, dead_children): Remove. - (reap_children): Don't try to keep separate track of how many - dead children we have, as this is too bug-prone. - Just ask the OS instead. - (vmsHandleChildTerm): Fix typo in error message; don't mention - child_handler. - - * main.c (main): Make sure we're not ignoring SIGCHLD/SIGCLD; - do this early, before we could possibly create a subprocess. - Just use the default behavior; don't have our own handler. - -1998-08-18 Eli Zaretskii <eliz@is.elta.co.il> - - * read.c (read_makefile) [__MSDOS__, WINDOWS32]: Add code to - recognize library archive members when dealing with drive spec - mess. Discovery and initial fix by George Racz <gracz@mincom.com>. - -1998-08-18 Paul D.

Smith <psmith@gnu.org> - - * make.texinfo: Added copyright year to the printed copy. Removed - the price from the manual. Change the top-level reference to - running make to be "Invoking make" instead of "make Invocation", - to comply with GNU doc standards. - - * make.h (__format__, __printf__): Added support for these in - __attribute__ macro. - (message, error, fatal): Use ... prototype form under __STDC__. - Add __format__ attributes for printf-style functions. - - * configure.in (AC_FUNC_VPRINTF): Check for vprintf()/_doprnt(). - - * misc.c (message, error, fatal): Add preprocessor stuff to enable - creation of variable-argument functions with appropriate - prototypes, that works with ANSI, pre-ANSI, varargs.h, stdarg.h, - v*printf(), _doprnt(), or none of the above. Culled from GNU - fileutils and slightly modified. - (makefile_error, makefile_error): Removed (merged into error() and - fatal(), respectively). - * amiga.c: Use them. - * ar.c: Use them. - * arscan.c: Use them. - * commands.c: Use them. - * expand.c: Use them. - * file.c: Use them. - * function.c: Use them. - * job.c: Use them. - * main.c: Use them. - * misc.c: Use them. - * read.c: Use them. - * remake.c: Use them. - * remote-cstms.c: Use them. - * rule.c: Use them. - * variable.c: Use them. - - * make.h (struct floc): New structure to store file location - information. - * commands.h (struct commands): Use it. - * variable.c (try_variable_definition): Use it. - * commands.c: Use it. - * default.c: Use it. - * file.c: Use it. - * function.c: Use it. - * misc.c: Use it. - * read.c: Use it. - * rule.c: Use it. - -1998-08-16 Paul Eggert <eggert@twinsun.com> - - * filedef.h (FILE_TIMESTAMP_PRINT_LEN_BOUND): Add 10, for nanoseconds. - -1998-08-16 Paul Eggert <eggert@twinsun.com> - - * filedef.h (FLOOR_LOG2_SECONDS_PER_YEAR): New macro. - (FILE_TIMESTAMP_PRINT_LEN_BOUND): Tighten bound, and try to - make it easier to understand. - -1998-08-14 Paul D.

Smith <psmith@gnu.org> - - * configure.in: Added glob/configure.in data. We'll have the glob - code include the regular make config.h, rather than creating its - own. - - * getloadavg.c (main): Change return type to int. - -1998-08-01 Paul Eggert <eggert@twinsun.com> - - * job.c (reap_children): Ignore unknown children. - -1998-07-31 Paul D.

Smith <psmith@gnu.org> - - * Version 3.76.94 released. - -1998-07-23 Paul D. Smith <psmith@gnu.org> - - * config.h.W32.template: Make sure all the #defines of macros here - have a value (e.g., use ``#define HAVE_STRING_H 1'' instead of - just ``#define HAVE_STRING_H''. Keeps the preprocessor happy in - some contexts. - - * make.h: Remove __attribute__((format...)) stuff; using it with - un-prototyped functions causes older GCC's to fail. - - * Version 3.76.93 released. - -1998-07-22 Paul D.

Without this change, make just - silently stops :-/. - -1998-07-16 Paul D. Smith <psmith@gnu.org> - - * make.texinfo: Removed "beta" version designator. - Updated ISBN for the next printing. - -1998-07-13 Paul Eggert <eggert@twinsun.com> - - * acinclude.m4: New AC_LFS macro to determine if special compiler - flags are needed to allow access to large files (e.g., Solaris 2.6). - * configure.in: Invoke it. - -1998-07-08 Eli Zaretskii <eliz@is.elta.co.il> - - * Makefile.DOS: track changes in Makefile.in. - -1998-07-07 Paul D.

Smith <psmith@gnu.org> - - * main.c (main): Keep track of the temporary filename created when - reading a makefile from stdin (-f-) and attempt to remove it - as soon as we know we're not going to re-exec. If we are, add it - to the exec'd make's cmd line with "-o" so the exec'd make doesn't - try to rebuild it. We still have a hole: if make re-execs then - the temporary file will never be removed. To fix this we'd need - a brand new option that meant "really delete this". - * AUTHORS, getopt.c, getopt1.c, getopt.h, main.c (print_version): - Updated mailing addresses. - -1998-06-08 Paul D.

Look up this target in the list of - pattern-specific variables and insert the variable set into the - queue to be searched. - - * filedef.h (struct file): Add a new field to hold the - previously-found pattern-specific variable reference. Add a new - flag to remember whether we already searched for this file. - - * rule.h (struct pattern_var): New structure for storing - pattern-specific variable values.

Smith <psmith@gnu.org> - - * read.c (read_makefile): Rewrite the entire target parsing - section to implement target-specific variables. In particular, we - cannot expand the entire line as soon as it's read in, since we - may want to evaluate parts of it with different variable contexts - active. Instead, start expanding from the beginning until we find - the `:' (or `::'), then determine what kind of line this is and - continue appropriately. - - * read.c (get_next_mword): New function to parse a makefile line - by "words", considering an entire variable or function as one - word.

Smith <psmith@gnu.org> - - * main.c (main): Don't pass included, rebuilt makefiles to - re-exec'd makes with -o. Reopens a possible loop, but it caused - too many problems. - -1998-03-02 Paul D. Smith <psmith@gnu.org> - - * variable.c (try_variable_definition): Implement ?=. - * make.texinfo (Setting): Document it. - -1998-02-28 Eli Zaretskii <eliz@is.elta.co.il> - - * job.c (start_job_command): Reset execute_by_shell after an empty - command, like ":", has been seen. - -Tue Oct 07 15:00:00 1997 Phil Brooks <phillip_brooks@hp.com> - - * make.h [WINDOWS32]: make case sensitivity configurable - * dir.c [WINDOWS32]: make case sensitivity configurable - * README.W32: Document case sensitivity - * config.ami: Share case warping code with Windows - -Mon Oct 6 18:48:45 CDT 1997 Rob Tulloh <rob_tulloh@dev.tivoli.com> - - * w32/subproc/sub_proc.c: Added support for MKS toolkit shell - (turn on HAVE_MKS_SHELL). - * read.c [WINDOWS32]: Fixed a problem with multiple target rules - reported by Gilbert Catipon (gcatipon@tibco.com). If multiple - path tokens in a rule did not have drive letters, make would - incorrectly concatenate the 2 tokens together. - * main.c/variable.c [WINDOWS32]: changed SHELL detection code to - follow what MSDOS did. In addition to watching for SHELL variable - updates, make's main will attempt to default the value of SHELL - before and after makefiles are parsed. - * job.c/job.h [WINDOWS32]: The latest changes made to enable use - of the GNUWIN32 shell from make could cause make to fail due to a - concurrency condition between parent and child processes. Make - now creates a batch file per job instead of trying to reuse the - same singleton batch file. - * job.c/job.h/function.c/config.h.W32 [WINDOWS32]: Renamed macro - from HAVE_CYGNUS_GNUWIN32_TOOLS to BATCH_MODE_ONLY_SHELL. Reworked - logic to reduce complexity. WINDOWS32 now uses the unixy_shell - variable to detect Bourne-shell compatible environments. There is - also a batch_mode_shell variable that determines whether not - command lines should be executed via script files. A WINDOWS32 - system with no sh.exe installed would have unixy_shell set to - FALSE and batch_mode_shell set to TRUE. If you have a unixy shell - that does not behave well when invoking things via 'sh -c xxx', - you may want to turn on BATCH_MODE_ONLY_SHELL and see if things - improve. - * NMakefile: Added /D DEBUG to debug build flags so that unhandled - exceptions could be debugged. - -Mon Oct 6 00:04:25 1997 Rob Tulloh <rob_tulloh@dev.tivoli.com> - - * main.c [WINDOWS32]: The function define_variable() does not - handle NULL. Test before calling it to set Path. - * main.c [WINDOWS32]: Search Path again after makefiles have been - parsed to detect sh.exe. - * job.c [WINDOWS32]: Added support for Cygnus GNU WIN32 tools. - To use, turn on HAVE_CYGNUS_GNUWIN32_TOOLS in config.h.W32. - * config.h.W32: Added HAVE_CYGNUS_GNUWIN32_TOOLS macro. - -Sun Oct 5 22:43:59 1997 John W. Eaton <jwe@bevo.che.wisc.edu> - - * glob/glob.c (glob_in_dir) [VMS]: Globbing shouldn't be - case-sensitive. - * job.c (child_execute_job) [VMS]: Use a VMS .com file if the - command contains a newline (e.g. from a define/enddef block). - * vmsify.c (vmsify): Return relative pathnames wherever possible. - * vmsify.c (vmsify): An input string like "../.." returns "[--]". - -Wed Oct 1 15:45:09 1997 Rob Tulloh <rob_tulloh@tivoli.com> - - * NMakefile: Changed nmake to $(MAKE). - * subproc.bat: Take the make command name from the command - line. If no command name was given, default to nmake. - * job.c [MSDOS, WINDOWS32]: Fix memory stomp: temporary file names - are now always created in heap memory. - * w32/subproc/sub_proc.c: New implementation of make_command_line() - which is more compatible with different Bourne shell implementations. - Deleted the now obsolete fix_command_line() function. - * main.c [WINDOWS32]: Any arbitrary spelling of Path can be - detected. Make will ensure that the special spelling `Path' is - inserted into the environment when the path variable is propagated - within itself and to make's children. - * main.c [WINDOWS32]: Detection of sh.exe was occurring too - soon. The 2nd check for the existence of sh.exe must come after - the call to read_all_makefiles(). - -Fri Sep 26 01:14:18 1997 <zinser@axp602.gsi.de> - - * makefile.com [VMS]: Fixed definition of sys. - * readme.vms: Comments on what's changed lately. - -Fri Sep 26 01:14:18 1997 John W.

Smith <psmith@baynetworks.com> - - * read.c (read_makefile): Reworked target detection again; the old - version had an obscure quirk. - -Fri Sep 19 09:20:49 1997 Paul D. Smith <psmith@baynetworks.com> - - * Version 3.76.1 released. - - * Makefile.am: Add loadavg files to clean rules. - - * configure.in (AC_OUTPUT): Remove stamp-config; no longer needed. - * Makefile.ami (distclean): Ditto. - * SMakefile (distclean): Ditto. - - * main.c (main): Arg count should be int, not char!

I believe this is a feature of - the way that execvp() is implemented on top of WINDOWS32 APIs. To - alleviate the problem, use the supplied process launch function in - the sub_proc library and suspend the parent process until the - child process has run. When the child exits, exit the parent make - with the exit code of the child make. - -Thu Aug 28 17:04:47 1997 Paul D.

Renamed a few functions for more clarity. - - * file.c (lookup_file,enter_file,file_hash_enter): Store filenames - in the hash table based on their "hash name". We can change this - while keeping the original target in "name". - (rehash_file): Renamed from "rename_file" to be more accurate. - Changes the hash name, but not the target name. - - * remake.c (update_file_1): Modify -d output for more detailed - VPATH info. If we don't need to rebuild, use the VPATH name. - (f_mtime): Don't search for vpath if we're ignoring it. Call - renamed function rehash_file.

For now, fully qualified - pathname along with st_mtime will be keys for files. - Fixed problem where vpath can be confused when files - are added to a directory after the directory has already been - read in. The code now attempts to reread the directory if it - discovers that the datestamp on the directory has changed since - it was cached by make. This problem only seems to occur on W32 - right now so it is lumped under port #ifdef WINDOWS32. - - * function.c: W32: call subproc library (CreateProcess()) instead of - fork/exec. - - * job.c: W32: Added the code to do fork/exec/waitpid style processing - on W32 systems via calls to subproc library. - - * main.c: W32: Several things added here. First, there is code - for dealing with PATH and SHELL defaults. Make tries to figure - out if the user has %PATH% set in the environment and sets it to - %Path% if it is not set already. Make also looks to see if sh.exe - is anywhere to be found. Code path through job.c will change - based on existence of a working Bourne shell. The checking for - default shell is done twice: once before makefiles are read in - and again after. Fall back to MSDOS style execution mode if no sh.exe - is found. Also added some debug support that allows user to pause make - with -D switch and attach a debugger. This is especially useful for - debugging recursive calls to make where problems appear only in the - sub-make. - - * make.h: W32: A few macros and header files for W32 support. - - * misc.c: W32: Added a function end_of_token_w32() to assist - in parsing code in read.c. - - * read.c: W32: Fixes similar to MSDOS which allow colon to - appear in filenames. Use of colon in filenames would otherwise - confuse make. - - * remake.c: W32: Added include of io.h to eliminate compiler - warnings. Added some code to default LIBDIR if it is not set - on W32. - - * variable.c: W32: Added support for detecting Path/PATH - and converting them to semicolon separated lists for make's - internal use. New function sync_Path_environment() - which is called in job.c and function.c before creating a new - process. Caller must set Path in environment since we don't - have fork() to do this for us. - - * vpath.c: W32: Added detection for filenames containing - forward or backward slashes. - - * NMakefile: W32: Visual C compatible makefile for use with nmake. - Use this to build GNU make the first time on Windows NT or Windows 95. - - * README.W32: W32: Contains some helpful notes. - - * build_w32.bat: W32: If you don't like nmake, use this the first - time you build GNU make on Windows NT or Windows 95. - - * config.h.W32: W32 version of config.h - - * subproc.bat: W32: A bat file used to build the - subproc library from the top-level NMakefile. Needed because - WIndows 95 (nmake) doesn't allow you to cd in a make rule. - - * w32/include/dirent.h - * w32/compat/dirent.c: W32: opendir, readdir, closedir, etc. - - * w32/include/pathstuff.h: W32: used by files needed functions - defined in pathstuff.c (prototypes). - - * w32/include/sub_proc.h: W32: prototypes for subproc.lib functions. - - * w32/include/w32err.h: W32: prototypes for w32err.c. - - * w32/pathstuff.c: W32: File and Path/Path conversion functions. - - * w32/subproc/build.bat: W32: build script for subproc library - if you don't wish to use nmake. - - * w32/subproc/NMakefile: W32: Visual C compatible makefile for use - with nmake. Used to build subproc library. - - * w32/subproc/misc.c: W32: subproc library support code - * w32/subproc/proc.h: W32: subproc library support code - * w32/subproc/sub_proc.c: W32: subproc library source code - * w32/subproc/w32err.c: W32: subproc library support code - -Mon May 13 14:37:42 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu> - - * Version 3.74.4. - - * GNUmakefile (vmsfiles): Fix typo. - - * GNUmakefile (amigafiles): Add amiga.h. - -Sun May 12 19:19:43 1996 Aaron Digulla <digulla@fh-konstanz.de> - - * dir.c: New function: amigafy() to fold filenames - Changes HASH() to HASHI() to fold filenames on Amiga. - Stringcompares use strieq() instead of streq() - The current directory on Amiga is "" instead of "." - * file.c: Likewise. - - * amiga.c: New function wildcard_expansion(). Allows to use - Amiga wildcards with $(wildcard ) - - * amiga.h: New file. Prototypes for amiga.c - - * function.c: Use special function wildcard_expansion() for - $(wildcard ) to allow Amiga wildcards - The current directory on Amiga is "" instead of "." - - * job.c: No Pipes on Amiga, too - (load_too_high) Neither on Amiga - ENV variable on Amiga are in a special directory and are not - passed as third argument to main(). - - * job.h: No envp on Amiga - - * make.h: Added HASHI(). This is the same as HASH() but converts - it's second parameter to lowercase on Amiga to fold filenames. - - * main.c: (main), variable.c Changed handling of ENV-vars. Make - stores now the names of the variables only and reads their contents - when they are accessed to reflect that these variables are really - global (ie. they CAN change WHILE make runs !) This handling is - made in lookup_variable() - - * Makefile.ami: renamed file.h to filedep.h - Updated dependencies - - * read.c: "find_semicolon" is declared as static but never defined. - No difference between Makefile and makefile on Amiga; added - SMakefile to *default_makefiles[]. - (read_makefile) SAS/C want's two_colon and pattern_percent be set - before use. - The current directory on Amiga is "" instead of "." - Strange #endif moved. - - * README.Amiga: updated feature list - - * SMakefile: Updated dependencies - - * variable.c: Handling of ENV variable happens inside lookup_variable() - -Sat May 11 17:58:32 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu> - - * variable.c (try_variable_definition): Count parens in lhs variable - refs to avoid seeing =/:=/+= inside a ref. - -Thu May 9 13:54:49 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu> - - * commands.c (fatal_error_signal) [SIGQUIT]: Make SIGQUIT check - conditional. - - * main.c (main): Use unsigned for fread return. - - * read.c (parse_file_seq): Use `int' for char arg to avoid widening - conflict issues. - * dep.h: Fix prototype. - - * function.c (expand_function) [_AMIGA]: Fix some typos. - (patsubst_expand): Make len vars unsigned. - - * GNUmakefile (globfiles): Add AmigaDOS support files. - (distfiles): Add $(amigafiles). - (amigafiles): New variable. - -Thu Nov 7 10:18:16 1995 Aaron Digulla <digulla@fh-konstanz.de> - - * Added Amiga support in commands.c, dir.c, function.c, - job.c, main.c, make.h, read.c, remake.c - * commands.c: Amiga has neither SIGHUP nor SIGQUIT - * dir.c: Amiga has filenames with Upper- and Lowercase, - but "FileName" is the same as "filename". Added strieq() - which is use to compare filenames. This is like streq() - on all other systems. Also there is no such thing as - "." under AmigaDOS. - * function.c: On Amiga, the environment is not passed as envp, - there are no pipes and Amiga can't fork. Use my own function - to create a new child. - * job.c: default_shell is "" (The system automatically chooses - a shell for me). Have to use the same workaround as MSDOS for - running batch commands. Added HAVE_SYS_PARAM_H. NOFILE isn't - known on Amiga. Cloned code to run children from MSDOS. Own - version of sh_chars[] and sh_cmds[]. No dup2() or dup() on Amiga. - * main.c: Force stack to 20000 bytes. Read environment from ENV: - device. On Amiga, exec_command() does return, so I exit() - afterwards. - * make.h: Added strieq() to compare filenames. - * read.c: Amiga needs special extension to have passwd. Only - one include-dir. "Makefile" and "makefile" are the same. - Added "SMakefile". Added special code to handle device names (xxx:) - and "./" in rules. - * remake.c: Only one lib-dir. Amiga link-libs are named "%s.lib" - instead of "lib%s.a". - * main.c, rule.c, variable.c: Avoid floats at all costs. - * vpath.c: Get rid of as many alloca()s as possible. - -Thu May 9 13:20:43 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu> - - * read.c (read_makefile): Grok `sinclude' as alias for `-include'. - -Wed Mar 20 09:52:27 1996 Roland McGrath <roland@charlie-brown.gnu.ai.mit.edu> - - * GNUmakefile (vmsfiles): New variable. - (distfiles): Include $(vmsfiles). - -Tue Mar 19 20:21:34 1996 Roland McGrath <roland@charlie-brown.gnu.ai.mit.edu> - - Merged VMS port from Klaus Kaempf <kkaempf@didymus.rmi.de>. - * make.h (PARAMS): New macro. - * config.h-vms: New file. - * makefile.com: New file. - * makefile.vms: New file. - * readme.vms: New file. - * vmsdir.h: New file. - * vmsfunctions.c: New file. - * vmsify.c: New file. - * file.h: Renamed to filedef.h to avoid conflict with VMS system hdr. - * ar.c: Added prototypes and changes for VMS. - * commands.c: Likewise. - * commands.h: Likewise. - * default.c: Likewise. - * dep.h: Likewise. - * dir.c: Likewise. - * expand.c: Likewise. - * file.c: Likewise. - * function.c: Likewise. - * implicit.c: Likewise. - * job.c: Likewise. - * job.h: Likewise. - * main.c: Likewise. - * make.h: Likewise. - * misc.c: Likewise. - * read.c: Likewise. - * remake.c: Likewise. - * remote-stub.c: Likewise. - * rule.c: Likewise. - * rule.h: Likewise. - * variable.c: Likewise. - * variable.h: Likewise. - * vpath.c: Likewise. - * compatMakefile (srcs): Rename file.h to filedef.h. - -Sat Aug 19 23:11:00 1995 Richard Stallman <rms@mole.gnu.ai.mit.edu> - - * remake.c (check_dep): For a secondary file, try implicit and - default rules if appropriate. - -Wed Aug 2 04:29:42 1995 Richard Stallman <rms@mole.gnu.ai.mit.edu> - - * remake.c (check_dep): If an intermediate file exists, - do consider its actual date. - -Sun Jul 30 00:49:53 1995 Richard Stallman <rms@mole.gnu.ai.mit.edu> - - * file.h (struct file): New field `secondary'. - * file.c (snap_deps): Check for .INTERMEDIATE and .SECONDARY. - (remove_intermediates): Don't delete .SECONDARY files. - -Sat Mar 2 16:26:52 1996 Roland McGrath <roland@charlie-brown.gnu.ai.mit.edu> - - * compatMakefile (srcs): Add getopt.h; prepend $(srcdir)/ to getopt*. - -Fri Mar 1 12:04:47 1996 Roland McGrath <roland@charlie-brown.gnu.ai.mit.edu> - - * Version 3.74.3. - - * remake.c (f_mtime): Move future modtime check before FILE is - clobbered by :: loop. - - * dir.c: Use canonical code from autoconf manual for dirent include. - [_D_NAMLEN]: Redefine NAMLEN using this. - (dir_contents_file_exists_p): Use NAMLEN macro. - (read_dirstream) [_DIRENT_HAVE_D_NAMLEN]: Only set d_namlen #if this. - - * compatMakefile (objs): Add missing backslash. - -Wed Feb 28 03:56:20 1996 Roland McGrath <roland@charlie-brown.gnu.ai.mit.edu> - - * default.c (default_terminal_rules): Remove + prefix from RCS cmds. - (default_variables): Put + prefix in $(CHECKOUT,v) value instead. - - * remake.c (f_mtime): Check for future timestamps; give error and mark - file as "failed to update". - -Fri Jan 12 18:09:36 1996 Roland McGrath <roland@churchy.gnu.ai.mit.edu> - - * job.c: Don't declare unblock_sigs; job.h already does. - -Sat Jan 6 16:24:44 1996 Roland McGrath <roland@churchy.gnu.ai.mit.edu> - - * acconfig.h (HAVE_SYSCONF_OPEN_MAX): #undef removed. - - * job.c (NGROUPS_MAX): Don't try to define this macro. - -Fri Dec 22 18:44:44 1995 Roland McGrath <roland@churchy.gnu.ai.mit.edu> - - * compatMakefile (GETOPT, GETOPT_SRC, GLOB): Variables removed. - (objs, srcs): Include their values here instead of references. - -Thu Dec 14 06:21:29 1995 Roland McGrath <roland@churchy.gnu.ai.mit.edu> - - * Version 3.74.2. - - * job.c (reap_children): Call unblock_sigs after start_job_command. - -Thu Dec 14 07:22:03 1995 Roland McGrath <roland@duality.gnu.ai.mit.edu> - - * dir.c (dir_setup_glob): Don't use lstat; glob never calls it anyway. - Avoid & before function names to silence bogus sunos4 compiler. - - * configure.in: Remove check for `sysconf (_SC_OPEN_MAX)'. - -Tue Dec 12 00:48:42 1995 Roland McGrath <roland@churchy.gnu.ai.mit.edu> - - * Version 3.74.1. - - * dir.c (read_dirstream): Fix braino: fill in the buffer when not - reallocating it! - -Mon Dec 11 22:26:15 1995 Roland McGrath <roland@churchy.gnu.ai.mit.edu> - - * misc.c (collapse_continuations): Fix skipping of trailing \s so - it can never dereference before the beginning of the array. - - * read.c (find_semicolon): Function removed. - (read_makefile): Don't use find_semicolon or remove_comments for - rule lines.

Otherwise we + may have a situation where a target's prerequisite was rebuilt but + not changed, so this target's rules weren't run, then + update_goal_chain() sees mtime_before_update != last_mtime and + thinks that the top-level target changed when it really didn't. + This can cause an infinite loop when remaking makefiles. + (update_goal_chain): If we get back to the top and we don't know + what the goal's last_mtime was, find it now. We need to know so + we can compare it to mtime_before_update later (this is only + crucial when remaking makefiles--should we only do it then?) + +1999-09-02 Paul D. Smith <psmith@gnu.org> + + * read.c (read_makefile): If "override" appears as the first + prerequisite, look further to ensure this is really a + target-specific variable definition, and not just some + prerequisite named "override". + +1999-09-01 Paul D. Smith <psmith@gnu.org> + + * function.c (IS_PATHSEP) [WINDOWS32]: Allow backslash separators + for W32 platforms. + * read.c (record_files) [WINDOWS32]: Allow backslash separators + for W32 platforms. + * implicit.c (pattern_search) [WINDOWS32]: Allow backslash + separators for W32 platforms. + + * configure.in (MAKE_HOST): Define it to be the canonical build + host info, now that we need AC_CANONICAL_HOST anyway (for large + file support). + * version.c (make_host): Define a variable to MAKE_HOST so we're + sure to get it from the local config.h. + * main.c (print_version): Use it in the version information. + * config.ami.template: Add MAKE_HOST. + * configh.dos.template: Ditto. + * config.h.W32.template: Ditto. + * config.h-vms.template: Ditto. + + * main.c (main): Close the jobserver file descriptors if we need + to re-exec ourselves. + Also print more reasonable error if users force -jN for submakes. + This may be common for a while until people use the jobserver + feature. If it happens, we ignore the existing jobserver stuff + and use whatever they specified on the commandline. + (define_makeflags): Fixed a long-standing bug: if a long name + only option comes immediately after a single letter option with no + argument, then the option string is constructed incorrectly. For + example, with -w and --jobserver-fds you get "-w-jobserver-fds..." + instead of "-w --jobserver-fds..."; add in an extra " -". + + * make.texinfo (Phony Targets): Add another example of using + .PHONY with subdirectories/recursive make. + +1999-08-30 Paul D. Smith <psmith@gnu.org> + + * README.W32.template: Renamed from README.W32 so it's + autogenerated during the dist.

Also added some + tests to make sure erase commands won't fail when executed in a + pristine build environment. + + * w32/subproc/sub_proc.c [WINDOWS32]: Added support for + HAVE_CYGWIN_SHELL. If you are using the Cygwin B20.1 release, it + is now possible to have have native support for this shell without + having to rely on klutzy BATCH_MODE_ONLY_SHELL. + + * config.h.W32 [WINDOWS32]: Added HAVE_CYGWIN_SHELL macro which + users can define if they want to build make to use this shell. + + * README.W32 [WINDOWS32]: Added informaton about + HAVE_CYGWIN_SHELL.

Smith <psmith@gnu.org> + + * remake.c (update_file): Move the considered check into the + double-colon rule loop, so we consider double-colon rules + individually (otherwise after the first is pruned, the rest won't + get run). + + * README.template: Minor changes. + + Remove the debugging features of the jobserver, so it no longer + writes distinct tokens to the pipe. Thus, we don't need to store + the token we get. A side effect of this is to remove a potential + "unavailable token" situation: make-1 invokes make-2 with its + special token and make-3 with a normal token; make-2 completes. + Now we're waiting for make-3 but using 2 tokens; our special token + is idle. In the new version we don't have special tokens per se, + we merely decide if we already have a child or not. If we don't, + we don't need a token. If we do, we have to get one to run the + next child. Similar for putting tokens back: if we're cleaning up + the last child, we don't put a token back. Otherwise, we do. + + * main.c: Add a new, internal flag --jobserver-fds instead of + overloading the meaning of -j. Remove job_slots_str and add the + stringlist jobserver_fds. + (struct command_switch): We don't need the int_string type. + (switches[]): Add a new option for --jobserver-fds and remove + conditions around -j. Make the description for the former 0 so it + doesn't print during "make --help". + (main): Rework jobserver parsing. If we got --jobserver-fds + make sure it's valid. We only get one and job_slots must be 0. + If we're the toplevel make (-jN without --jobserver-fds) create + the pipe and write generic tokens. + Create the stringlist struct for the submakes. + Clean up the stringlist where necessary. + (init_switches): Remove int_string handling. + (print_usage): Don't print internal flags (description ptr is 0). + (decode_switches): Remove int_string handling. + (define_makeflags): Remove int_string handling. + + * job.c: Remove my_job_token flag and all references to the + child->job_token field. + (free_job_token): Remove this and merge it into free_child(). + (reap_children): Rework the "reaped a child" logic slightly. + Don't call defunct free_job_token anymore. Always call + free_child, even if we're dying. + (free_child): If we're not freeing the only child, put a token + back in the pipe. Then, if we're dying, don't bother to free. + (new_job): If we are using the jobserver, loop checking to see if + a) there are no children or b) we get a token from the pipe. + + * job.h (struct child): Remove the job_token field. + +1999-08-20 Paul D. Smith <psmith@gnu.org> + + * variable.c (try_variable_definition): Allocate for variable + expansion in f_append with a simple variable: if we're looking at + target-specific variables we don't want to trash the buffer. + Noticed by Reiner Beninga <Reiner.Beninga@mchp.siemens.de>. + +1999-08-16 Eli Zaretskii <eliz@is.elta.co.il> + + * main.c (main) [__MSDOS__]: Mirror any backslashes in argv[0], to + avoid problems in shell commands that use backslashes as escape + characters. + +1999-08-16 Paul D. Smith <psmith@gnu.org> + + * Version 3.77.93 released. + +1999-08-13 Paul D. Smith <psmith@gnu.org + + * function.c (func_if): New function $(if ...) based on the + original by Han-Wen but reworked quite a bit. + (function_table): Add it. + * NEWS: Introduce it. + * make.texinfo (If Function): Document it. + + * job.c (free_job_token): Check for EINTR when writing tokens to + the jobserver pipe. + +1999-08-12 Paul D. Smith <psmith@gnu.org> + + Another jobserver algorithm change. We conveniently forgot that + the blocking bit is shared by all users of the pipe, it's not a + per-process setting. Since we have many make processes all + sharing the pipe we can't use the blocking bit as a signal handler + flag. Instead, we'll dup the pipe's read FD and have the SIGCHLD + handler close the dup'd FD. This will cause the read() to fail + with EBADF the next time we invoke it, so we know we need to reap + children. We then re-dup and reap. + + * main.c (main): Define the job_rfd variable to hold the dup'd FD. + Actually dup the read side of the pipe. Don't bother setting the + blocking bit on the file descriptor. + * make.h: Declare the job_rfd variable. + * job.c (child_handler): If the dup'd jobserver pipe is open, + close it and assign -1 to job_rfd to notify the main program that + we got a SIGCHLD. + (start_job_command): Close the dup'd FD before exec'ing children. + Since we open and close this thing so often it doesn't seem + worth it to use the close-on-exec bit. + (new_job): Remove code for testing/setting the blocking bit. + Instead of EAGAIN, test for EBADF. If the dup'd FD has been + closed, re-dup it before we reap children. + + * function.c (func_shell): Be a little more accurate about the + length of the error string to allocate. + + * expand.c (variable_expand_for_file): If there's no filenm info + (say, from a builtin command) then reset reading_file to 0. + +1999-08-09 Paul D. Smith <psmith@gnu.org> + + * maintMakefile: Use g in sed (s///g) to replace >1 variable per + line. + + * Makefile.DOS.template [__MSDOS__]: Fix mostlyclean-aminfo to + remove the right files. + +1999-08-01 Eli Zaretskii <eliz@is.elta.co.il> + + * function.c (msdos_openpipe) [__MSDOS__]: *Really* return a FILE + ptr. + +1999-08-01 Paul D. Smith <psmith@gnu.org> + + New jobserver algorithm to avoid a possible hole where we could + miss SIGCHLDs and get into a deadlock. The original algorithm was + suggested by Roland McGrath with a nice refinement by Paul Eggert. + Many thanks as well to Tim Magill and Howard Chu, who also + provided many viable ideas and critiques. We all had a fun week + dreaming up interesting ways to use and abuse UNIX syscalls :). + + Previously we could miss a SIGCHLD if it happened after we reaped + the children but before we re-entered the blocking read. If this + happened to all makes and/or all children, make would never wake + up. + + We avoid this by having the SIGCHLD handler reset the blocking bit + on the jobserver pipe read FD (normally read does block in this + algorithm). Now if the handler is called between the time we reap + and the time we read(), and there are no tokens available, the + read will merely return with EAGAIN instead of blocking. + + * main.c (main): Set the blocking bit explicitly here. + * job.c (child_handler): If we have a jobserver pipe, set the + non-blocking bit for it. + (start_waiting_job): Move the token stuff back to new_job; if we + do it here then we're not controlling the number of remote jobs + started! + (new_job): Move the check for job slots to _after_ we've created a + child structure. If the read returns without getting a token, set + the blocking bit then try to reap_children. + + * make.h (EINTR_SET): Define to test errno if EINTR is available, + or 0 otherwise. Just some code cleanup. + * arscan.c (ar_member_touch): Use it. + * function.c (func_shell): Use it. + * job.c (reap_children): Use it. + * remake.c (touch_file): Use it. + +1999-07-28 Paul D. Smith <psmith@gnu.org> + + * make.h: Define _() and N_() macros as passthrough to initiate + NLS support. + * <all>: Add _()/N_() around translatable strings. + +1999-07-27 Paul D.

Smith <psmith@gnu.org> + + * Version 3.77.91 released. + + * configure.in: Changes to the boostrapping code: if build.sh.in + doesn't exist configure spits an error and generates an empty + build.sh file which causes make to be confused. + * maintMakefile: Don't build README early. + +1999-07-23 Paul D. Smith <psmith@gnu.org> + + * job.c (my_job_token): This variable controls whether we've + handed our personal token to a subprocess or not. Note we could + probably infer this from the value of job_slots_used, but it's + clearer to just keep it separately. Job_slots_used isn't really + relevant when running the job server. + (free_job_token): New function: free a job token. If we don't + have one, no-op. If we have the personal token, reclaim it. If + we have another token, write it back to the pipe. + (reap_children): Call free_job_token. + (free_child): Call free_job_token. + (start_job_command): Remove duplicate test for '+' in the command. + If we don't appear to be running a recursive make, close the + jobserver filedescriptors. + (start_waiting_job): If our personal token is available, use that + instead of going to the server pipe. + (*): Add the token value to many debugging statements, and print + the child target name in addition to the ptr hex value. + Change the default "no token" value from '\0' to '-' so it looks + better in the output. + + * main.c (main): Install the child_handler with sigaction() + instead of signal() if we have it. On SysV systems, signal() uses + SysV semantics which are a pain. But sigaction() always does what + we want. + (main): If we got job server FDs from the environment, test them + to see if they're open. If not, the parent make closed them + because it didn't think we were a submake. Print a warning and + suggestion to use "+" on the submake invocation, and hard-set to + -j1 for this instance of make. + (main): Change the algorithm for assigning slots to be more + robust. Previously make checked to see if it thought a subprocess + was a submake and if so, didn't give it a token. Since make's + don't consume tokens we could spawn many of makes fighting for a + small number of tokens. Plus this is unreliable because submakes + might not be recognized by the parent (see above) then all the + tokens could be used up by unrecognized makes, and no one could + run. Now every make consumes a token from its parent. However, + the make can also use this token to spawn a child. If the make + wants more than one, it goes to the jobserver pipe. Thus there + will never be more than N makes running for -jN, and N*2 processes + (N makes and their N children). Every make can always run at + least one job, and we'll never deadlock. (Note the closing of the + pipe for non-submakes also solves this, but this is still a better + algorithm.) So! Only put N-1 tokens into the pipe, since the + topmost make keeps one for itself. + + * configure.in: Find sigaction. Disable job server support unless + the system provides it, in addition to either waitpid() or + wait3(). + +1999-07-22 Rob Tulloh <rob_tulloh@dev.tivoli.com> + + * arscan.c (ar_member_touch) [WINDOWS32]: The ar_date field is a + string on Windows, not a timestamp. + +1999-07-21 Paul D.

Use --enable-dmalloc + with configure to enable it. + + * function.c (function_table_entry): Whoops! The function.c + rewrite breaks backward compatibility: all text to a function is + broken into arguments, and extras are ignored. So $(sort a,b,c) + returns "a"! Etc. Ouch. Fix it by making a positive value in + the REQUIRED_ARGS field mean exactly that many arguments to the + function; any "extras" are considered part of the last argument as + before.

If necessary, + create the pipe and seed it with tokens. Set the non-blocking bit + for the read fd. Enable the signal handler for SIGCHLD even if we + have a non-hanging wait; it's needed to interrupt the select() in + job.c:start_waiting_job(). + + * make.h: Declare job_fds[]. + + * job.h (struct child): Add job_token field to store the token for + this job (if any). + + * job.c (reap_children): When a child is fully reaped, release the + token back into the pipe. + (free_child): If the child to be freed still has a token, put it + back. + (new_job): Initialize the job_token member. + (start_waiting_job): For local jobs, if we're using the pipe, get + a token before we check the load, etc. We do this by performing a + non-blocking read in a loop. If the read fails, no token is + available. Do a select on the fd to wait for a token. We need to + re-enable the signal handler for SIGCHLD even if we have a + non-hanging waitpid() or wait3(), so that the signal will + interrupt the select() and we can wake up to reap children. + (child_handler): Re-enable the signal handler. The count is still + kept although it's not needed or used unless you don't have + waitpid() or wait3(). + +1999-04-10 Paul D. Smith <psmith@gnu.org> + + * main.c (main): Reset the considered bit on all the makefiles if + something failed to update; we need to examine them again if they + appear as normal targets in order to get the proper error message. + +1999-04-09 Paul D. Smith <psmith@gnu.org> + + Performance enhancement from Tim Magill <tim.magill@telops.gte.com>. + + * remake.c (update_file): If you have large numbers of + dependencies and you run in parallel, make can spend considerable + time each pass through the graph looking at branches it has + already seen. Since we only reap_children() when starting a pass, + not in the middle, if a branch has been seen already in that pass + nothing interesting can happen until the next pass. So, we toggle + a bit saying whether we've seen this target in this pass or not. + (update_goal_chain): Initially set the global considered toggle to + 1, since all targets initialize their boolean to 0. At the end of + each pass, toggle the global considered variable. + * filedef.h (struct file): Per-file considered toggle bit. + * file.c: New global toggle variable considered. + +1999-04-05 Paul D. Smith <psmith@gnu.org> + + * arscan.c (ar_scan): Added support for ARFZMAG (compressed + archives?) for Digital UNIX C++. Information provided by + Patrick E. Krogel <pekrogel@mtu.edu>. + (ar_member_touch): Ditto. + +1999-04-03 Paul D. Smith <psmith@gnu.org> + + * remake.c (f_mtime): If: a) we found a file and b) we didn't + create it and c) it's not marked as an implicit target and d) it + is marked as an intermediate target, then it was so marked due to + an .INTERMEDIATE special target, but it already existed in the + directory. In this case, unset the intermediate flag so we won't + delete it when make is done. It feels like it would be cleaner to + put this check in update_file_1() but I worry it'll get missed... + +1999-04-01 Paul D. Smith <psmith@gnu.org> + + * job.c (construct_command_argv_internal): Use bcopy() to copy + overlapping strings, rather than strcpy(). ISO C says the latter + is undefined. Found this in a bug report from 1996! Ouch! + +1999-03-31 Paul D. Smith <psmith@gnu.org> + + * read.c (readline): Ignore carriage returns at the end of the + line, to allow Windows-y CRLF line terminators. + +1999-03-30 Paul D. Smith <psmith@gnu.org> + + * configure.in: Don't put build.sh here, since build.sh.in doesn't + exist initially. This cause autoreconf and automake to fail when + run on a clean CVS checkout. Instead, we create build.sh in the + Makefile (see below). + + * Makefile.am: Remove BUILT_SOURCES; this is no longer relevant. + Put those files directly into EXTRA_DIST so they're distributed. + Create a local build rule to create build.sh. + Create a local maintainer-clean rule to delete all the funky + maintainers files. + + * maintMakefile: Makefile.in depends on README, since automake + fails if it doesn't exist. Also don't remove glob/Makefile.in + here, as it causes problems. + +1999-03-26 Paul D. Smith <psmith@gnu.org> + + * configure.in: Substitute GLOBLIB if we need the link the + glob/libglob.a library. + * Makefile.am (make_LDADD): Use the subst variable GLOBLIB so we + don't link the local libglob.a at all if we don't need it. + * build.template: Don't compile glob/*.o unless we want globlib. + * maintMakefile (build.sh.in): Substitute the glob/*.o files + separately. + +1999-03-25 Paul D. Smith <psmith@gnu.org> + + * make.texinfo: Various typos and additions, pointed out by James + G. Sack <jsack@dornfeld.com>. + +1999-03-22 Paul D. Smith <psmith@gnu.org> + + * make.texinfo (Functions): Add a new section documenting the new + $(error ...) and $(warning ...) functions. Also updated copyright + dates. + * NEWS: Updated for the new functions. + * function.c (func_error): Implement the new $(error ...) and + $(warning ...) functions. + (function_table): Insert new functions into the table. + (func_firstword): Don't call find_next_token() with argv[0] + itself, since that function modifies the pointer. + * function.c: Cleanups and slight changes to the new method of + calling functions. + +1999-03-20 Han-Wen Nienhuys <hanwen@cs.uu.nl> + + * function.c: Rewrite to use one C function per make function, + instead of a huge switch statement. Also allows some cleanup of + multi-architecture issues, and a cleaner API which makes things + like func_apply() simple. + + * function.c (func_apply): Initial implementation. Expand either + a builtin function or a make variable in the context of some + arguments, provided as $1, $2, ... $N. + +1999-03-19 Eli Zaretskii <eliz@is.elta.co.il> +1999-03-19 Rob Tulloh <rob_tulloh@dev.tivoli.com> + + * job.c (construct_command_argv_internal): Don't treat _all_ + backslashes as escapes, only those which really escape a special + character. This allows most normal "\" directory separators to be + treated normally. + +1999-03-05 Paul D. Smith <psmith@gnu.org> + + * configure.in: Check for a system strdup(). + * misc.c (xstrdup): Created. Suggestion by Han-Wen Nienhuys + <hanwen@cs.uu.nl>. + * make.h: Prototype xstrdup(). + * remake.c (library_search): Use it. + * main.c (main): Use it. + (find_and_set_default_shell): Use it. + * job.c (construct_command_argv_internal): Use it. + * dir.c (find_directory): Use it. + + * Makefile.am, configure.in: Use AC_SUBST_FILE to insert the + maintMakefile instead of "include", to avoid automake 1.4 + incompatibility. + +1999-03-04 Paul D. Smith <psmith@gnu.org> + + * amiga.c, amiga.h, ar.c, arscan.c, commands.c, commands.h, + * default.c, dep.h, dir.c, expand.c, file.c, filedef.h, function.c, + * implicit.c, job.c, job.h, main.c, make.h, misc.c, read.c, remake.c + * remote-cstms.c, remote-stub.c, rule.h, variable.c, variable.h, + * vpath.c, Makefile.ami, NMakefile.template, build.template, + * makefile.vms: Updated FSF address in the copyright notice. + + * variable.c (try_variable_definition): If we see a conditional + variable and we decide to set it, re-type it as recursive so it + will be expanded properly later. + +1999-02-22 Paul D. Smith <psmith@gnu.org> + + * NEWS: Mention new .LIBPATTERNS feature. + + * make.texinfo (Libraries/Search): Describe the use and + ramifications of the new .LIBPATTERNS variable. + + * remake.c (library_search): Instead of searching only for the + hardcoded expansion "libX.a" for a library reference "-lX", we + obtain a list of patterns from the .LIBPATTERNS variable and + search those in order. + + * default.c: Added a new default variable .LIBPATTERNS. The + default for UNIX is "lib%.so lib%.a". Amiga and DOS values are + also provided. + + * read.c: Remove bogus HAVE_GLOB_H references; always include + vanilla glob.h. + +1999-02-21 Paul D. Smith <psmith@gnu.org> + + * function.c (expand_function): Set value to 0 to avoid freeing it. + * variable.c (pop_variable_scope): Free the value of the variable. + (try_variable_definition): For simple variables, use + allocated_variable_expand() to avoid stomping on the variable + buffer when we still need it for other things. + + * arscan.c: Modified to support AIX 4.3 big archives. The changes + are based on information provided by Phil Adams + <padams@austin.ibm.com>. + +1999-02-19 Paul D. Smith <psmith@gnu.org> + + * configure.in: Check to see if the GNU glob library is already + installed on the system. If so, _don't_ add -I./glob to the + compile line. Using the system glob code with the local headers + is very bad mojo! + Rewrite SCCS macros to use more autoconf facilities. + + * Makefile.am: Move -Iglob out of INCLUDES; it'll get added to + CPPFLAGS by configure now. + Automake 1.4 introduced its own "include" feature which conflicts + with the maintMakefile stuff. A hack that seems to work is add a + space before the include :-/. + + * build.template: Move -Iglob out of the compile line; it'll get + added to CPPFLAGS by configure now. + +1999-02-16 Glenn D. Wolf <Glenn_Wolf@email.sps.mot.com> + + * arscan.c (ar_scan) [VMS]: Initialized VMS_member_date before + calling lbr$get_index since if the archive is empty, + VMS_get_member_info won't get called at all, and any leftover date + will be used. This bug shows up if any member of any archive is + made, followed by a dependency check on a different, empty + archive. + +1998-12-13 Martin Zinser <zinser@decus.decus.de> + + * config.h-vms [VMS]: Set _POSIX_C_SOURCE.

Smith <psmith@gnu.org> + + * job.c (start_job_command): If the command list resolves to no + chars at all (e.g.: "foo:;$(empty)") then command_ptr is NULL; + quit early. + +1998-10-12 Andreas Schwab <schwab@issan.cs.uni-dortmund.de> + + * rule.c (print_rule_data_base): Ignore num_pattern_rules if it is + zero. + +1998-10-09 Paul D.

Smith <psmith@gnu.org> + + * read.c (read_makefile): If we hit the "missing separator" error, + check for the common case of 8 spaces instead of a TAB and give an + extra comment to help people out. + +1998-08-29 Paul Eggert <eggert@twinsun.com> + + * configure.in (AC_STRUCT_ST_MTIM_NSEC): + Renamed from AC_STRUCT_ST_MTIM. + + * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Likewise. + Port to UnixWare 2.1.2 and pedantic Solaris 2.6. + + * acconfig.h (ST_MTIM_NSEC): + Renamed from HAVE_ST_MTIM, with a new meaning. + + * filedef.h (FILE_TIMESTAMP_FROM_S_AND_NS): + Use new ST_MTIM_NSEC macro. + +1998-08-26 Paul D. Smith <psmith@gnu.org> + + * remake.c (check_dep): For any intermediate file, not just + secondary ones, try implicit and default rules if no explicit + rules are given. I'm not sure why this was restricted to + secondary rules in the first place. + +1998-08-24 Paul D. Smith <psmith@gnu.org> + + * make.texinfo (Special Targets): Update documentation for + .INTERMEDIATE: if used with no dependencies, then it does nothing; + old docs said it marked all targets as intermediate, which it + didn't... and which would be silly :). + + * implicit.c (pattern_search): If we find a dependency in our + internal tables, make sure it's not marked intermediate before + accepting it as a found_file[]. + +1998-08-20 Paul D. Smith <psmith@gnu.org> + + * ar.c (ar_glob): Use existing alpha_compare() with qsort. + (ar_glob_alphacompare): Remove it. + + Modify Paul Eggert's patch so we don't abandon older systems: + + * configure.in: Warn the user if neither waitpid() nor wait3() is + available. + + * job.c (WAIT_NOHANG): Don't syntax error on ancient hosts. + (child_handler, dead_children): Define these if WAIT_NOHANG is not + available. + (reap_children): Only track the dead_children count if no + WAIT_NOHANG. Otherwise, it's a boolean. + + * main.c (main): Add back signal handler if no WAIT_NOHANG is + available; only use default signal handler if it is. + +1998-08-20 Paul Eggert <eggert@twinsun.com> + + Install a more robust signal handling mechanism for systems which + support it. + + * job.c (WAIT_NOHANG): Define to a syntax error if our host + is truly ancient; this should never happen. + (child_handler, dead_children): Remove. + (reap_children): Don't try to keep separate track of how many + dead children we have, as this is too bug-prone. + Just ask the OS instead. + (vmsHandleChildTerm): Fix typo in error message; don't mention + child_handler. + + * main.c (main): Make sure we're not ignoring SIGCHLD/SIGCLD; + do this early, before we could possibly create a subprocess. + Just use the default behavior; don't have our own handler. + +1998-08-18 Eli Zaretskii <eliz@is.elta.co.il> + + * read.c (read_makefile) [__MSDOS__, WINDOWS32]: Add code to + recognize library archive members when dealing with drive spec + mess.

In addition to watching for SHELL variable + updates, make's main will attempt to default the value of SHELL + before and after makefiles are parsed. + * job.c/job.h [WINDOWS32]: The latest changes made to enable use + of the GNUWIN32 shell from make could cause make to fail due to a + concurrency condition between parent and child processes. Make + now creates a batch file per job instead of trying to reuse the + same singleton batch file. + * job.c/job.h/function.c/config.h.W32 [WINDOWS32]: Renamed macro + from HAVE_CYGNUS_GNUWIN32_TOOLS to BATCH_MODE_ONLY_SHELL. Reworked + logic to reduce complexity. WINDOWS32 now uses the unixy_shell + variable to detect Bourne-shell compatible environments. There is + also a batch_mode_shell variable that determines whether not + command lines should be executed via script files. A WINDOWS32 + system with no sh.exe installed would have unixy_shell set to + FALSE and batch_mode_shell set to TRUE.

The checking for + default shell is done twice: once before makefiles are read in + and again after. Fall back to MSDOS style execution mode if no sh.exe + is found. Also added some debug support that allows user to pause make + with -D switch and attach a debugger. This is especially useful for + debugging recursive calls to make where problems appear only in the + sub-make. + + * make.h: W32: A few macros and header files for W32 support. + + * misc.c: W32: Added a function end_of_token_w32() to assist + in parsing code in read.c. + + * read.c: W32: Fixes similar to MSDOS which allow colon to + appear in filenames.

(This is never a problem with GNU -@code{make}.) - -Different @code{make} programs have incompatible suffix lists and -implicit rules, and this sometimes creates confusion or misbehavior. So -it is a good idea to set the suffix list explicitly using only the -suffixes you need in the particular Makefile, like this: - -@example -.SUFFIXES: -.SUFFIXES: .c .o -@end example - -@noindent -The first line clears out the suffix list, the second introduces all -suffixes which may be subject to implicit rules in this Makefile. - -Don't assume that @file{.} is in the path for command execution. When -you need to run programs that are a part of your package during the -make, please make sure that it uses @file{./} if the program is built as -part of the make or @file{$(srcdir)/} if the file is an unchanging part -of the source code. Without one of these prefixes, the current search -path is used. - -The distinction between @file{./} (the @dfn{build directory}) and -@file{$(srcdir)/} (the @dfn{source directory}) is important because -users can build in a separate directory using the @samp{--srcdir} option -to @file{configure}. A rule of the form: - -@smallexample -foo.1 : foo.man sedscript - sed -e sedscript foo.man > foo.1 -@end smallexample - -@noindent -will fail when the build directory is not the source directory, because -@file{foo.man} and @file{sedscript} are in the the source directory. - -When using GNU @code{make}, relying on @samp{VPATH} to find the source -file will work in the case where there is a single dependency file, -since the @code{make} automatic variable @samp{$<} will represent the -source file wherever it is. (Many versions of @code{make} set @samp{$<} -only in implicit rules.) A Makefile target like - -@smallexample -foo.o : bar.c - $(CC) -I. -I$(srcdir) $(CFLAGS) -c bar.c -o foo.o -@end smallexample - -@noindent -should instead be written as - -@smallexample -foo.o : bar.c - $(CC) -I. -I$(srcdir) $(CFLAGS) -c $< -o $@@ -@end smallexample - -@noindent -in order to allow @samp{VPATH} to work correctly. When the target has -multiple dependencies, using an explicit @samp{$(srcdir)} is the easiest -way to make the rule work well. For example, the target above for -@file{foo.1} is best written as: - -@smallexample -foo.1 : foo.man sedscript - sed -e $(srcdir)/sedscript $(srcdir)/foo.man > $@@ -@end smallexample - -GNU distributions usually contain some files which are not source -files---for example, Info files, and the output from Autoconf, Automake, -Bison or Flex. Since these files normally appear in the source -directory, they should always appear in the source directory, not in the -build directory. So Makefile rules to update them should put the -updated files in the source directory. - -However, if a file does not appear in the distribution, then the -Makefile should not put it in the source directory, because building a -program in ordinary circumstances should not modify the source directory -in any way. - -Try to make the build and installation targets, at least (and all their -subtargets) work correctly with a parallel @code{make}. - -@node Utilities in Makefiles -@section Utilities in Makefiles - -Write the Makefile commands (and any shell scripts, such as -@code{configure}) to run in @code{sh}, not in @code{csh}. Don't use any -special features of @code{ksh} or @code{bash}. - -The @code{configure} script and the Makefile rules for building and -installation should not use any utilities directly except these: - -@c dd find -@c gunzip gzip md5sum -@c mkfifo mknod tee uname - -@example -cat cmp cp diff echo egrep expr false grep install-info -ln ls mkdir mv pwd rm rmdir sed sleep sort tar test touch true -@end example - -The compression program @code{gzip} can be used in the @code{dist} rule. - -Stick to the generally supported options for these programs. For -example, don't use @samp{mkdir -p}, convenient as it may be, because -most systems don't support it. - -It is a good idea to avoid creating symbolic links in makefiles, since a -few systems don't support them. - -The Makefile rules for building and installation can also use compilers -and related programs, but should do so via @code{make} variables so that the -user can substitute alternatives. Here are some of the programs we -mean: - -@example -ar bison cc flex install ld ldconfig lex -make makeinfo ranlib texi2dvi yacc -@end example - -Use the following @code{make} variables to run those programs: - -@example -$(AR) $(BISON) $(CC) $(FLEX) $(INSTALL) $(LD) $(LDCONFIG) $(LEX) -$(MAKE) $(MAKEINFO) $(RANLIB) $(TEXI2DVI) $(YACC) -@end example - -When you use @code{ranlib} or @code{ldconfig}, you should make sure -nothing bad happens if the system does not have the program in question. -Arrange to ignore an error from that command, and print a message before -the command to tell the user that failure of this command does not mean -a problem. (The Autoconf @samp{AC_PROG_RANLIB} macro can help with -this.) - -If you use symbolic links, you should implement a fallback for systems -that don't have symbolic links. - -Additional utilities that can be used via Make variables are: - -@example -chgrp chmod chown mknod -@end example - -It is ok to use other utilities in Makefile portions (or scripts) -intended only for particular systems where you know those utilities -exist. - -@node Command Variables -@section Variables for Specifying Commands - -Makefiles should provide variables for overriding certain commands, options, -and so on. - -In particular, you should run most utility programs via variables. -Thus, if you use Bison, have a variable named @code{BISON} whose default -value is set with @samp{BISON = bison}, and refer to it with -@code{$(BISON)} whenever you need to use Bison. - -File management utilities such as @code{ln}, @code{rm}, @code{mv}, and -so on, need not be referred to through variables in this way, since users -don't need to replace them with other programs. - -Each program-name variable should come with an options variable that is -used to supply options to the program. Append @samp{FLAGS} to the -program-name variable name to get the options variable name---for -example, @code{BISONFLAGS}. (The names @code{CFLAGS} for the C -compiler, @code{YFLAGS} for yacc, and @code{LFLAGS} for lex, are -exceptions to this rule, but we keep them because they are standard.) -Use @code{CPPFLAGS} in any compilation command that runs the -preprocessor, and use @code{LDFLAGS} in any compilation command that -does linking as well as in any direct use of @code{ld}. - -If there are C compiler options that @emph{must} be used for proper -compilation of certain files, do not include them in @code{CFLAGS}. -Users expect to be able to specify @code{CFLAGS} freely themselves. -Instead, arrange to pass the necessary options to the C compiler -independently of @code{CFLAGS}, by writing them explicitly in the -compilation commands or by defining an implicit rule, like this: - -@smallexample -CFLAGS = -g -ALL_CFLAGS = -I. $(CFLAGS) -.c.o: - $(CC) -c $(CPPFLAGS) $(ALL_CFLAGS) $< -@end smallexample - -Do include the @samp{-g} option in @code{CFLAGS}, because that is not -@emph{required} for proper compilation. You can consider it a default -that is only recommended. If the package is set up so that it is -compiled with GCC by default, then you might as well include @samp{-O} -in the default value of @code{CFLAGS} as well. - -Put @code{CFLAGS} last in the compilation command, after other variables -containing compiler options, so the user can use @code{CFLAGS} to -override the others. - -@code{CFLAGS} should be used in every invocation of the C compiler, -both those which do compilation and those which do linking. - -Every Makefile should define the variable @code{INSTALL}, which is the -basic command for installing a file into the system. - -Every Makefile should also define the variables @code{INSTALL_PROGRAM} -and @code{INSTALL_DATA}. (The default for each of these should be -@code{$(INSTALL)}.) Then it should use those variables as the commands -for actual installation, for executables and nonexecutables -respectively. Use these variables as follows: - -@example -$(INSTALL_PROGRAM) foo $(bindir)/foo -$(INSTALL_DATA) libfoo.a $(libdir)/libfoo.a -@end example - -Optionally, you may prepend the value of @code{DESTDIR} to the target -filename. Doing this allows the installer to create a snapshot of the -installation to be copied onto the real target filesystem later. Do not -set the value of @code{DESTDIR} in your Makefile, and do not include it -in any installed files. With support for @code{DESTDIR}, the above -examples become: - -@example -$(INSTALL_PROGRAM) foo $(DESTDIR)$(bindir)/foo -$(INSTALL_DATA) libfoo.a $(DESTDIR)$(libdir)/libfoo.a -@end example - -@noindent -Always use a file name, not a directory name, as the second argument of -the installation commands. Use a separate command for each file to be -installed. - -@node Directory Variables -@section Variables for Installation Directories - -Installation directories should always be named by variables, so it is -easy to install in a nonstandard place. The standard names for these -variables are described below. They are based on a standard filesystem -layout; variants of it are used in SVR4, 4.4BSD, Linux, Ultrix v4, and -other modern operating systems. - -These two variables set the root for the installation. All the other -installation directories should be subdirectories of one of these two, -and nothing should be directly installed into these two directories. - -@table @samp -@item prefix -A prefix used in constructing the default values of the variables listed -below.

This directory should normally be @file{/usr/local/etc}, but -write it as @file{$(prefix)/etc}. -(If you are using Autoconf, write it as @samp{@@sysconfdir@@}.) - -Do not install executables here in this directory (they probably belong -in @file{$(libexecdir)} or @file{$(sbindir)}). Also do not install -files that are modified in the normal course of their use (programs -whose purpose is to change the configuration of the system excluded). -Those probably belong in @file{$(localstatedir)}. - -@item sharedstatedir -The directory for installing architecture-independent data files which -the programs modify while they run. This should normally be -@file{/usr/local/com}, but write it as @file{$(prefix)/com}. -(If you are using Autoconf, write it as @samp{@@sharedstatedir@@}.) - -@item localstatedir -The directory for installing data files which the programs modify while -they run, and that pertain to one specific machine.

So installing the header files this way is -only useful with GCC. Sometimes this is not a problem because some -libraries are only really intended to work with GCC. But some libraries -are intended to work with other compilers. They should install their -header files in two places, one specified by @code{includedir} and one -specified by @code{oldincludedir}. - -@item oldincludedir -The directory for installing @samp{#include} header files for use with -compilers other than GCC. This should normally be @file{/usr/include}. -(If you are using Autoconf, you can write it as @samp{@@oldincludedir@@}.) - -The Makefile commands should check whether the value of -@code{oldincludedir} is empty. If it is, they should not try to use -it; they should cancel the second installation of the header files. - -A package should not replace an existing header in this directory unless -the header came from the same package. Thus, if your Foo package -provides a header file @file{foo.h}, then it should install the header -file in the @code{oldincludedir} directory if either (1) there is no -@file{foo.h} there or (2) the @file{foo.h} that exists came from the Foo -package. - -To tell whether @file{foo.h} came from the Foo package, put a magic -string in the file---part of a comment---and @code{grep} for that string. -@end table - -Unix-style man pages are installed in one of the following: - -@table @samp -@item mandir -The top-level directory for installing the man pages (if any) for this -package.

The idea of having a uniform set of -variable names for installation directories is to enable the user to -specify the exact same values for several different GNU packages. In -order for this to be useful, all the packages must be designed so that -they will work sensibly when the user does so. - -@node Standard Targets -@section Standard Targets for Users - -All GNU programs should have the following targets in their Makefiles: - -@table @samp -@item all -Compile the entire program. This should be the default target. This -target need not rebuild any documentation files; Info files should -normally be included in the distribution, and DVI files should be made -only when explicitly asked for. - -By default, the Make rules should compile and link with @samp{-g}, so -that executable programs have debugging symbols. Users who don't mind -being helpless can strip the executables later if they wish. - -@item install -Compile the program and copy the executables, libraries, and so on to -the file names where they should reside for actual use. If there is a -simple test to verify that a program is properly installed, this target -should run that test. - -Do not strip executables when installing them. Devil-may-care users can -use the @code{install-strip} target to do that. - -If possible, write the @code{install} target rule so that it does not -modify anything in the directory where the program was built, provided -@samp{make all} has just been done. This is convenient for building the -program under one user name and installing it under another. - -The commands should create all the directories in which files are to be -installed, if they don't already exist. This includes the directories -specified as the values of the variables @code{prefix} and -@code{exec_prefix}, as well as all subdirectories that are needed. -One way to do this is by means of an @code{installdirs} target -as described below. - -Use @samp{-} before any command for installing a man page, so that -@code{make} will ignore any errors. This is in case there are systems -that don't have the Unix man page documentation system installed. - -The way to install Info files is to copy them into @file{$(infodir)} -with @code{$(INSTALL_DATA)} (@pxref{Command Variables}), and then run -the @code{install-info} program if it is present. @code{install-info} -is a program that edits the Info @file{dir} file to add or update the -menu entry for the given Info file; it is part of the Texinfo package. -Here is a sample rule to install an Info file: - -@comment This example has been carefully formatted for the Make manual. -@comment Please do not reformat it without talking to roland@gnu.ai.mit.edu. -@smallexample -$(DESTDIR)$(infodir)/foo.info: foo.info - $(POST_INSTALL) -# There may be a newer info file in . than in srcdir. - -if test -f foo.info; then d=.; \ - else d=$(srcdir); fi; \ - $(INSTALL_DATA) $$d/foo.info $(DESTDIR)$@@; \ -# Run install-info only if it exists. -# Use `if' instead of just prepending `-' to the -# line so we notice real errors from install-info. -# We use `$(SHELL) -c' because some shells do not -# fail gracefully when there is an unknown command. - if $(SHELL) -c 'install-info --version' \ - >/dev/null 2>&1; then \ - install-info --dir-file=$(DESTDIR)$(infodir)/dir \ - $(DESTDIR)$(infodir)/foo.info; \ - else true; fi -@end smallexample - -When writing the @code{install} target, you must classify all the -commands into three categories: normal ones, @dfn{pre-installation} -commands and @dfn{post-installation} commands. @xref{Install Command -Categories}. - -@item uninstall -Delete all the installed files---the copies that the @samp{install} -target creates. - -This rule should not modify the directories where compilation is done, -only the directories where files are installed. - -The uninstallation commands are divided into three categories, just like -the installation commands. @xref{Install Command Categories}. - -@item install-strip -Like @code{install}, but strip the executable files while installing -them.

For example, the @samp{mostlyclean} -target for GCC does not delete @file{libgcc.a}, because recompiling it -is rarely necessary and takes a lot of time. - -@item maintainer-clean -Delete almost everything from the current directory that can be -reconstructed with this Makefile. This typically includes everything -deleted by @code{distclean}, plus more: C source files produced by -Bison, tags tables, Info files, and so on. - -The reason we say ``almost everything'' is that running the command -@samp{make maintainer-clean} should not delete @file{configure} even if -@file{configure} can be remade using a rule in the Makefile. More generally, -@samp{make maintainer-clean} should not delete anything that needs to -exist in order to run @file{configure} and then begin to build the -program. This is the only exception; @code{maintainer-clean} should -delete everything else that can be rebuilt. - -The @samp{maintainer-clean} target is intended to be used by a maintainer of -the package, not by ordinary users. You may need special tools to -reconstruct some of the files that @samp{make maintainer-clean} deletes. -Since these files are normally included in the distribution, we don't -take care to make them easy to reconstruct. If you find you need to -unpack the full distribution again, don't blame us. - -To help make users aware of this, the commands for the special -@code{maintainer-clean} target should start with these two: - -@smallexample -@@echo 'This command is intended for maintainers to use; it' -@@echo 'deletes files that may need special tools to rebuild.' -@end smallexample - -@item TAGS -Update a tags table for this program. -@c ADR: how? - -@item info -Generate any Info files needed. The best way to write the rules is as -follows: - -@smallexample -info: foo.info - -foo.info: foo.texi chap1.texi chap2.texi - $(MAKEINFO) $(srcdir)/foo.texi -@end smallexample - -@noindent -You must define the variable @code{MAKEINFO} in the Makefile. It should -run the @code{makeinfo} program, which is part of the Texinfo -distribution. - -Normally a GNU distribution comes with Info files, and that means the -Info files are present in the source directory. Therefore, the Make -rule for an info file should update it in the source directory. When -users build the package, ordinarily Make will not update the Info files -because they will already be up to date. - -@item dvi -Generate DVI files for all Texinfo documentation. -For example: - -@smallexample -dvi: foo.dvi - -foo.dvi: foo.texi chap1.texi chap2.texi - $(TEXI2DVI) $(srcdir)/foo.texi -@end smallexample - -@noindent -You must define the variable @code{TEXI2DVI} in the Makefile. It should -run the program @code{texi2dvi}, which is part of the Texinfo -distribution.@footnote{@code{texi2dvi} uses @TeX{} to do the real work -of formatting. @TeX{} is not distributed with Texinfo.} Alternatively, -write just the dependencies, and allow GNU @code{make} to provide the command. - -@item dist -Create a distribution tar file for this program. The tar file should be -set up so that the file names in the tar file start with a subdirectory -name which is the name of the package it is a distribution for. This -name can include the version number. - -For example, the distribution tar file of GCC version 1.40 unpacks into -a subdirectory named @file{gcc-1.40}. - -The easiest way to do this is to create a subdirectory appropriately -named, use @code{ln} or @code{cp} to install the proper files in it, and -then @code{tar} that subdirectory. - -Compress the tar file file with @code{gzip}. For example, the actual -distribution file for GCC version 1.40 is called @file{gcc-1.40.tar.gz}. - -The @code{dist} target should explicitly depend on all non-source files -that are in the distribution, to make sure they are up to date in the -distribution. -@ifset CODESTD -@xref{Releases, , Making Releases}. -@end ifset -@ifclear CODESTD -@xref{Releases, , Making Releases, standards, GNU Coding Standards}. -@end ifclear - -@item check -Perform self-tests (if any).

You should not assume that -@file{$(bindir)} is in the search path. - -@item installdirs -It's useful to add a target named @samp{installdirs} to create the -directories where files are installed, and their parent directories. -There is a script called @file{mkinstalldirs} which is convenient for -this; you can find it in the Texinfo package. -@c It's in /gd/gnu/lib/mkinstalldirs. -You can use a rule like this: - -@comment This has been carefully formatted to look decent in the Make manual. -@comment Please be sure not to make it extend any further to the right.--roland -@smallexample -# Make sure all installation directories (e.g. $(bindir)) -# actually exist by making them if necessary. -installdirs: mkinstalldirs - $(srcdir)/mkinstalldirs $(bindir) $(datadir) \ - $(libdir) $(infodir) \ - $(mandir) -@end smallexample - -This rule should not modify the directories where compilation is done. -It should do nothing but create installation directories. -@end table - -@node Install Command Categories -@section Install Command Categories - -@cindex pre-installation commands -@cindex post-installation commands -When writing the @code{install} target, you must classify all the -commands into three categories: normal ones, @dfn{pre-installation} -commands and @dfn{post-installation} commands. - -Normal commands move files into their proper places, and set their -modes. They may not alter any files except the ones that come entirely -from the package they belong to. - -Pre-installation and post-installation commands may alter other files; -in particular, they can edit global configuration files or data bases. - -Pre-installation commands are typically executed before the normal -commands, and post-installation commands are typically run after the -normal commands. - -The most common use for a post-installation command is to run -@code{install-info}. This cannot be done with a normal command, since -it alters a file (the Info directory) which does not come entirely and -solely from the package being installed. It is a post-installation -command because it needs to be done after the normal command which -installs the package's Info files. - -Most programs don't need any pre-installation commands, but we have the -feature just in case it is needed. - -To classify the commands in the @code{install} rule into these three -categories, insert @dfn{category lines} among them. A category line -specifies the category for the commands that follow. - -A category line consists of a tab and a reference to a special Make -variable, plus an optional comment at the end. There are three -variables you can use, one for each category; the variable name -specifies the category. Category lines are no-ops in ordinary execution -because these three Make variables are normally undefined (and you -@emph{should not} define them in the makefile). - -Here are the three possible category lines, each with a comment that -explains what it means: - -@smallexample - $(PRE_INSTALL) # @r{Pre-install commands follow.} - $(POST_INSTALL) # @r{Post-install commands follow.} - $(NORMAL_INSTALL) # @r{Normal commands follow.} -@end smallexample - -If you don't use a category line at the beginning of the @code{install} -rule, all the commands are classified as normal until the first category -line. If you don't use any category lines, all the commands are -classified as normal. - -These are the category lines for @code{uninstall}: - -@smallexample - $(PRE_UNINSTALL) # @r{Pre-uninstall commands follow.} - $(POST_UNINSTALL) # @r{Post-uninstall commands follow.} - $(NORMAL_UNINSTALL) # @r{Normal commands follow.} -@end smallexample - -Typically, a pre-uninstall command would be used for deleting entries -from the Info directory. - -If the @code{install} or @code{uninstall} target has any dependencies -which act as subroutines of installation, then you should start -@emph{each} dependency's commands with a category line, and start the -main target's commands with a category line also. This way, you can -ensure that each command is placed in the right category regardless of -which of the dependencies actually run. - -Pre-installation and post-installation commands should not run any -programs except for these: - -@example -[ basename bash cat chgrp chmod chown cmp cp dd diff echo -egrep expand expr false fgrep find getopt grep gunzip gzip -hostname install install-info kill ldconfig ln ls md5sum -mkdir mkfifo mknod mv printenv pwd rm rmdir sed sort tee -test touch true uname xargs yes -@end example - -@cindex binary packages -The reason for distinguishing the commands in this way is for the sake -of making binary packages. Typically a binary package contains all the -executables and other files that need to be installed, and has its own -method of installing them---so it does not need to run the normal -installation commands. But installing the binary package does need to -execute the pre-installation and post-installation commands. - -Programs to build binary packages work by extracting the -pre-installation and post-installation commands.
