Make will automatically insert any + variable definitions from the environment value of `MAKEFLAGS' or from + the command line, into the `MAKEFLAGS' value exported to children. The + `MAKEOVERRIDES' variable previously included in the value of `$(MAKE)' + for sub-makes is now included in `MAKEFLAGS' instead. As before, you can + reset `MAKEOVERRIDES' in your makefile to avoid putting all the variables + in the environment when its size is limited. + +* If `.DELETE_ON_ERROR' appears as a target, Make will delete the target of + a rule if it has changed when its commands exit with a nonzero status, + just as when the commands get a signal. + +* The automatic variable `$+' is new. It lists all the dependencies like + `$^', but preserves duplicates listed in the makefile. This is useful + for linking rules, where library files sometimes need to be listed twice + in the link order. + +* You can now specify the `.IGNORE' and `.SILENT' special targets with + dependencies to limit their effects to those files. If a file appears as + a dependency of `.IGNORE', then errors will be ignored while running the + commands to update that file. Likewise if a file appears as a dependency + of `.SILENT', then the commands to update that file will not be printed + before they are run. (This change was made to conform to POSIX.2.) + +Version 3.71 + +* The automatic variables `$(@D)', `$(%D)', `$(*D)', `$(<D)', `$(?D)', and + `$(^D)' now omit the trailing slash from the directory name. (This change + was made to comply with POSIX.2.) + +* The source distribution now includes the Info files for the Make manual. + There is no longer a separate distribution containing Info and DVI files. + +* You can now set the variables `binprefix' and/or `manprefix' in + Makefile.in (or on the command line when installing) to install GNU make + under a name other than `make' (i.e., ``make binprefix=g install'' + installs GNU make as `gmake'). + +* The built-in Texinfo rules use the new variables `TEXI2DVI_FLAGS' for + flags to the `texi2dvi' script, and `MAKEINFO_FLAGS' for flags to the + Makeinfo program. + +* The exit status of Make when it runs into errors is now 2 instead of 1. + The exit status is 1 only when using -q and some target is not up to date. + (This change was made to comply with POSIX.2.) + +Version 3.70 + +* It is no longer a fatal error to have a NUL character in a makefile. + You should never put a NUL in a makefile because it can have strange + results, but otherwise empty lines full of NULs (such as produced by + the `xmkmf' program) will always work fine. + +* The error messages for nonexistent included makefiles now refer to the + makefile name and line number where the `include' appeared, so Emacs's + C-x ` command takes you there (in case it's a typo you need to fix). + +Version 3.69 + +* Implicit rule search for archive member references is now done in the + opposite order from previous versions: the whole target name `LIB(MEM)' + first, and just the member name and parentheses `(MEM)' second. + +* Make now gives an error for an unterminated variable or function reference. + For example, `$(foo' with no matching `)' or `${bar' with no matching `}'. + +* The new default variable `MAKE_VERSION' gives the version number of + Make, and a string describing the remote job support compiled in (if any). + Thus the value (in this release) is something like `3.69' or `3.69-Customs'. + +* Commands in an invocation of the `shell' function are no longer run with + a modified environment like target commands are. As in versions before + 3.68, they now run with the environment that `make' started with. We + have reversed the change made in version 3.68 because it turned out to + cause a paradoxical situation in cases like: + + export variable = $(shell echo value) + + When Make attempted to put this variable in the environment for a target + command, it would try expand the value by running the shell command + `echo value'. In version 3.68, because it constructed an environment + for that shell command in the same way, Make would begin to go into an + infinite loop and then get a fatal error when it detected the loop. + +* The commands given for `.DEFAULT' are now used for phony targets with no + commands. + +Version 3.68 + +* You can list several archive member names inside parenthesis: + `lib(mem1 mem2 mem3)' is equivalent to `lib(mem1) lib(mem2) lib(mem3)'. + +* You can use wildcards inside archive member references. For example, + `lib(*.o)' expands to all existing members of `lib' whose names end in + `.o' (e.g. `lib(a.o) lib(b.o)'); `*.a(*.o)' expands to all such members + of all existing files whose names end in `.a' (e.g. `foo.a(a.o) + foo.a(b.o) bar.a(c.o) bar.a(d.o)'. + +* A suffix rule `.X.a' now produces two pattern rules: + (%.o): %.X # Previous versions produced only this. + %.a: %.X # Now produces this as well, just like other suffixes. + +* The new flag `--warn-undefined-variables' says to issue a warning message + whenever Make expands a reference to an undefined variable. + +* The new `-include' directive is just like `include' except that there is + no error (not even a warning) for a nonexistent makefile. + +* Commands in an invocation of the `shell' function are now run with a + modified environment like target commands are, so you can use `export' et + al to set up variables for them. They used to run with the environment + that `make' started with. + +Version 3.66 + +* `make --version' (or `make -v') now exits immediately after printing + the version number. + +Version 3.65 + +* Make now supports long-named members in `ar' archive files. + +Version 3.64 + +* Make now supports the `+=' syntax for a variable definition which appends + to the variable's previous value. See the section `Appending More Text + to Variables' in the manual for full details. + +* The new option `--no-print-directory' inhibits the `-w' or + `--print-directory' feature. Make turns on `--print-directory' + automatically if you use `-C' or `--directory', and in sub-makes; some + users have found this behavior undesirable. + +* The built-in implicit rules now support the alternative extension + `.txinfo' for Texinfo files, just like `.texinfo' and `.texi'. + +Version 3.63 + +* Make now uses a standard GNU `configure' script. See the new file + INSTALL for the new (and much simpler) installation procedure. + +* There is now a shell script to build Make the first time, if you have no + other `make' program. `build.sh' is created by `configure'; see README. + +* GNU Make now completely conforms to the POSIX.2 specification for `make'. + +* Elements of the `$^' and `$?' automatic variables that are archive + member references now list only the member name, as in Unix and POSIX.2. + +* You should no longer ever need to specify the `-w' switch, which prints + the current directory before and after Make runs. The `-C' switch to + change directory, and recursive use of Make, now set `-w' automatically. + +* Multiple double-colon rules for the same target will no longer have their + commands run simultaneously under -j, as this could result in the two + commands trying to change the file at the same time and interfering with + one another. + +* The `SHELL' variable is now never taken from the environment. + Each makefile that wants a shell other than the default (/bin/sh) must + set SHELL itself. SHELL is always exported to child processes. + This change was made for compatibility with POSIX.2. + +* Make now accepts long options. There is now an informative usage message + that tells you what all the options are and what they do. Try `make --help'. + +* There are two new directives: `export' and `unexport'. All variables are + no longer automatically put into the environments of the commands that + Make runs. Instead, only variables specified on the command line or in + the environment are exported by default. To export others, use: + export VARIABLE + or you can define variables with: + export VARIABLE = VALUE + or: + export VARIABLE := VALUE + You can use just: + export + or: + .EXPORT_ALL_VARIABLES: + to get the old behavior. See the node `Variables/Recursion' in the manual + for a full description. + +* The commands from the `.DEFAULT' special target are only applied to + targets which have no rules at all, not all targets with no commands. + This change was made for compatibility with Unix make. + +* All fatal error messages now contain `***', so they are easy to find in + compilation logs. + +* Dependency file names like `-lNAME' are now replaced with the actual file + name found, as with files found by normal directory search (VPATH). + The library file `libNAME.a' may now be found in the current directory, + which is checked before VPATH; the standard set of directories (/lib, + /usr/lib, /usr/local/lib) is now checked last. + See the node `Libraries/Search' in the manual for full details. + +* A single `include' directive can now specify more than one makefile to + include, like this: + include file1 file2 + You can also use shell file name patterns in an `include' directive: + include *.mk + +* The default directories to search for included makefiles, and for + libraries specified with `-lNAME', are now set by configuration. + +* You can now use blanks as well as colons to separate the directories in a + search path for the `vpath' directive or the `VPATH' variable. + +* You can now use variables and functions in the left hand side of a + variable assignment, as in "$(foo)bar = value". + +* The `MAKE' variable is always defined as `$(MAKE_COMMAND) $(MAKEOVERRIDES)'. + The `MAKE_COMMAND' variable is now defined to the name with which make + was invoked. + +* The built-in rules for C++ compilation now use the variables `$(CXX)' and + `$(CXXFLAGS)' instead of `$(C++)' and `$(C++FLAGS)'. The old names had + problems with shells that cannot have `+' in environment variable names. + +* The value of a recursively expanded variable is now expanded when putting + it into the environment for child processes. This change was made for + compatibility with Unix make. + +* A rule with no targets before the `:' is now accepted and ignored. + This change was made for compatibility with SunOS 4 make. + We do not recommend that you write your makefiles to take advantage of this. + +* The `-I' switch can now be used in MAKEFLAGS, and are put there + automatically just like other switches. + +Version 3.61 + +* Built-in rules for C++ source files with the `.C' suffix. + We still recommend that you use `.cc' instead. + +* If commands are given too many times for a single target, + the last set given is used, and a warning message is printed. + +* Error messages about makefiles are in standard GNU error format, + so C-x ` in Emacs works on them. + +* Dependencies of pattern rules which contain no % need not actually exist + if they can be created (just like dependencies which do have a %). + +Version 3.60 + +* A message is always printed when Make decides there is nothing to be done. + It used to be that no message was printed for top-level phony targets + (because "`phony' is up to date" isn't quite right). Now a different + message "Nothing to be done for `phony'" is printed in that case. + +* Archives on AIX now supposedly work. + +* When the commands specified for .DEFAULT are used to update a target, + the $< automatic variable is given the same value as $@ for that target. + This is how Unix make behaves, and this behavior is mandated by POSIX.2. + +Version 3.59 + +* The -n, -q, and -t options are not put in the `MAKEFLAGS' and `MFLAG' + variables while remaking makefiles, so recursive makes done while remaking + makefiles will behave properly. + +* If the special target `.NOEXPORT' is specified in a makefile, + only variables that came from the environment and variables + defined on the command line are exported. + +Version 3.58 + +* Suffix rules may have dependencies (which are ignored). + +Version 3.57 + +* Dependencies of the form `-lLIB' are searched for as /usr/local/lib/libLIB.a + as well as libLIB.a in /usr/lib, /lib, the current directory, and VPATH. + +Version 3.55 + +* There is now a Unix man page for GNU Make. It is certainly not a replacement +for the Texinfo manual, but it documents the basic functionality and the +switches. For full documentation, you should still read the Texinfo manual. +Thanks to Dennis Morse of Stanford University for contributing the initial +version of this. + +* Variables which are defined by default (e.g., `CC') will no longer be put +into the environment for child processes. (If these variables are reset by the +environment, makefiles, or the command line, they will still go into the +environment.) + +* Makefiles which have commands but no dependencies (and thus are always + considered out of date and in need of remaking), will not be remade (if they + were being remade only because they were makefiles). This means that GNU + Make will no longer go into an infinite loop when fed the makefiles that + `imake' (necessary to build X Windows) produces. + +* There is no longer a warning for using the `vpath' directive with an explicit +pathname (instead of a `%' pattern). + +Version 3.51 + +* When removing intermediate files, only one `rm' command line is printed, +listing all file names. + +* There are now automatic variables `$(^D)', `$(^F)', `$(?D)', and `$(?F)'. +These are the directory-only and file-only versions of `$^' and `$?'. + +* Library dependencies given as `-lNAME' will use "libNAME.a" in the current +directory if it exists. + +* The automatic variable `$($/)' is no longer defined. + +* Leading `+' characters on a command line make that line be executed even +under -n, -t, or -q (as if the line contained `$(MAKE)'). + +* For command lines containing `$(MAKE)', `${MAKE}', or leading `+' characters, +only those lines are executed, not their entire rules. +(This is how Unix make behaves for lines containing `$(MAKE)' or `${MAKE}'.) + +Version 3.50 + +* Filenames in rules will now have ~ and ~USER expanded. + +* The `-p' output has been changed so it can be used as a makefile. +(All information that isn't specified by makefiles is prefaced with comment +characters.) + +Version 3.49 + +* The % character can be quoted with backslash in implicit pattern rules, +static pattern rules, `vpath' directives, and `patsubst', `filter', and +`filter-out' functions. A warning is issued if a `vpath' directive's +pattern contains no %. + +* The `wildcard' variable expansion function now expands ~ and ~USER. + +* Messages indicating failed commands now contain the target name: + make: *** [target] Error 1 + +* The `-p' output format has been changed somewhat to look more like +makefile rules and to give all information that Make has about files. + +Version 3.48 + +Version 3.47 + +* The `-l' switch with no argument removes any previous load-average limit. + +* When the `-w' switch is in effect, and Make has updated makefiles, +it will write a `Leaving directory' messagfe before re-executing itself. +This makes the `directory change tracking' changes to Emacs's compilation +commands work properly. + +Version 3.46 + +* The automatic variable `$*' is now defined for explicit rules, +as it is in Unix make. + +Version 3.45 + +* The `-j' switch is now put in the MAKEFLAGS and MFLAGS variables when +specified without an argument (indicating infinite jobs). +The `-l' switch is not always put in the MAKEFLAGS and MFLAGS variables. + +* Make no longer checks hashed directories after running commands. +The behavior implemented in 3.41 caused too much slowdown. + +Version 3.44 + +* A dependency is NOT considered newer than its dependent if +they have the same modification time. The behavior implemented +in 3.43 conflicts with RCS. + +Version 3.43 + +* Dependency loops are no longer fatal errors. + +* A dependency is considered newer than its dependent if +they have the same modification time. + +Version 3.42 + +* The variables F77 and F77FLAGS are now set by default to $(FC) and +$(FFLAGS). Makefiles designed for System V make may use these variables in +explicit rules and expect them to be set. Unfortunately, there is no way to +make setting these affect the Fortran implicit rules unless FC and FFLAGS +are not used (and these are used by BSD make). + +Version 3.41 + +* Make now checks to see if its hashed directories are changed by commands. +Other makes that hash directories (Sun, 4.3 BSD) don't do this. + +Version 3.39 + +* The `shell' function no longer captures standard error output. + +Version 3.32 + +* A file beginning with a dot can be the default target if it also contains +a slash (e.g., `../bin/foo'). (Unix make allows this as well.) + +Version 3.31 + +* Archive member names are truncated to 15 characters. + +* Yet more USG stuff. + +* Minimal support for Microport System V (a 16-bit machine and a +brain-damaged compiler). This has even lower priority than other USG +support, so if it gets beyond trivial, I will take it out completely. + +* Revamped default implicit rules (not much visible change). + +* The -d and -p options can come from the environment. + +Version 3.30 + +* Improved support for USG and HPUX (hopefully). + +* A variable reference like `$(foo:a=b)', if `a' contains a `%', is +equivalent to `$(patsubst a,b,$(foo))'. + +* Defining .DEFAULT with no deps or commands clears its commands. + +* New default implicit rules for .S (cpp, then as), and .sh (copy and make +executable). All default implicit rules that use cpp (even indirectly), use +$(CPPFLAGS). + +Version 3.29 + +* Giving the -j option with no arguments gives you infinite jobs. + +Version 3.28 + +* New option: "-l LOAD" says not to start any new jobs while others are +running if the load average is not below LOAD (a floating-point number). + +* There is support in place for implementations of remote command execution +in Make. See the file remote.c. + +Version 3.26 + +* No more than 10 directories will be kept open at once. +(This number can be changed by redefining MAX_OPEN_DIRECTORIES in dir.c.) + +Version 3.25 + +* Archive files will have their modification times recorded before doing +anything that might change their modification times by updating an archive +member. + +Version 3.20 + +* The `MAKELEVEL' variable is defined for use by makefiles. + +Version 3.19 + +* The recursion level indications in error messages are much shorter than +they were in version 3.14. + +Version 3.18 + +* Leading spaces before directives are ignored (as documented). + +* Included makefiles can determine the default goal target. +(System V Make does it this way, so we are being compatible). + +Version 3.14. + +* Variables that are defaults built into Make will not be put in the +environment for children. This just saves some environment space and, +except under -e, will be transparent to sub-makes. + +* Error messages from sub-makes will indicate the level of recursion. + +* Hopefully some speed-up for large directories due to a change in the +directory hashing scheme. + +* One child will always get a standard input that is usable. + +* Default makefiles that don't exist will be remade and read in. + +Version 3.13. + +* Count parentheses inside expansion function calls so you can +have nested calls: `$(sort $(foreach x,a b,$(x)))'. + +Version 3.12. + +* Several bug fixes, including USG and Sun386i support. + +* `shell' function to expand shell commands a la ` + +* If the `-d' flag is given, version information will be printed. + +* The `-c' option has been renamed to `-C' for compatibility with tar. + +* The `-p' option no longer inhibits other normal operation. + +* Makefiles will be updated and re-read if necessary. + +* Can now run several commands at once (parallelism), -j option. + +* Error messages will contain the level of Make recursion, if any. + +* The `MAKEFLAGS' and `MFLAGS' variables will be scanned for options after +makefiles are read. + +* A double-colon rule with no dependencies will always have its commands run. +(This is how both the BSD and System V versions of Make do it.) + +Version 3.05 + +(Changes from versions 1 through 3.05 were never recorded.

To do this, first run +`configure' as described in INSTALL. Then, instead of typing `make' to +build the program, type `sh build.sh'. This should compile the program +in the current directory. Then you will have a Make program that you can +use for `make install', or whatever else. + +It has been reported that the XLC 1.2 compiler on AIX 3.2 is buggy such +that if you compile make with `cc -O' on AIX 3.2, it will not work correctly. +It is said that using `cc' without `-O' does work. + +One area that is often a problem in configuration and porting is the code +to check the system's current load average. To make it easier to test and +debug this code, you can do `make check-loadavg' to see if it works +properly on your system. (You must run `configure' beforehand, but you +need not build Make itself to run this test.) + +See the file NEWS for what has changed since previous releases. + +GNU Make is fully documented in make.texinfo.
