2013-09-12Enhance the output sync mode.Paul Smith1-3/+8
Create a new file, output.c, and collect functions that generate output there. We introduce a new global context specifying where output should go (to stdout or to a sync file), and the lowest level output generator chooses where to write output based on that context. This allows us to set the context globally, and all operations that write output (including functions like $(info ...) etc.) will use it. Removed the "--trace=dir" capability. It was too confusing. If you have directory tracking enabled then output sync will print the enter/leave message for each synchronized block. If you don't want that, disable directory tracking.
2013-06-22Minor fix in build_w32.bat.Eli Zaretskii1-0/+1
build_w32.bat (LinkGCC): Prevent a comment from being displayed at build time.
2013-05-17Fix a bug in build_w32.bat when building a released tarball.Eli Zaretskii1-1/+1
build_w32.bat: Copy config.h.W32 to config.h regardless of whether or not we are building from SCM.
2013-05-03Fix interfacing with and remaking dynamic objects on MS-Windows.Eli Zaretskii1-1/+3
load.c (load_object, load_file): Accept an additional argument DLP and return in it a pointer that can be used to unload the dynamic object. read.c (eval): Call load_file with an additional argument, and record the pointer returned there in the 'struct file' object of dynamic objects in that object's 'struct file'. commands.c (execute_file_commands): Unload dynamic objects before remaking them, to avoid failure to remake if the OS doesn't allow overwriting objects that are in use. filedef.h (struct file): New member dlopen_ptr. gnumake.h (GMK_EXPORT): Define to dllexport/dllimport decorations for Windows and to nothing on other platforms. (gmk_eval, gmk_expand, gmk_add_function): Add GMK_EXPORT qualifier to prototypes. makeint.h (MAIN): Define before including gnumake.h, to give correct dllexport decorations to exported functions. (load_file): Adjust prototype. loadapi.c: Don't include gnumake.h, since makeint.h already includes it, and takes care of defining MAIN before doing so. build_w32.bat (LinkGCC): Produce an import library for functions exported by Make for loadable dynamic objects. w32/compat/posixfcn.c (dlclose): New function. w32/include/dlfcn.h (dlclose): Add prototype. scripts/features/load: Fix signatures of testload_gmk_setup and explicit_setup, to bring them in line with the documentation.
2013-04-27Support --output-sync on MS-Windows.Eli Zaretskii1-1/+6
w32/compat/posixfcn.c: New file, with emulations of Posix functions and Posix functionality for MS-Windows. w32/subproc/sub_proc.c: Include io.h. (process_noinherit): New function, forces a file descriptor to not be inherited by child processes. (process_easy): Accept two additional arguments, and use them to set up the standard output and standard error handles of the child process. w32/include/sub_proc.h (process_easy): Adjust prototype. (process_noinherit): Add prototype. read.c [WINDOWS32]: Include windows.h and sub_proc.h. makeint.h (LOCALEDIR) [WINDOWS32}: Define to NULL if not defined. This is needed because the MS-Windows build doesn't have a canonical place for LOCALEDIR. (WIN32_LEAN_AND_MEAN) [WINDOWS32]: Define, to avoid getting from windows.h header too much stuff that could conflict with the code. main.c <sync_mutex>: New static variable. <switches>: Add support for "--sync-mutex" switch. (decode_output_sync_flags): Decode the --sync-mutex= switch. (prepare_mutex_handle_string) [WINDOWS32]: New function. (main): Add "output-sync" to .FEATURES. job.h (CLOSE_ON_EXEC) [WINDOWS32]: Define to call process_noinherit. (F_GETFD, F_SETLKW, F_WRLCK, F_UNLCK, struct flock) [WINDOWS32]: New macros. (RECORD_SYNC_MUTEX): New macro, a no-op for Posix platforms. (sync_handle_t): New typedef. job.c <sync_handle>: Change type to sync_handle_t. (FD_NOT_EMPTY): Seek to the file's end. Suggested by Frank Heckenbach <f.heckenbach@fh-soft.de>. (pump_from_tmp_fd) [WINDOWS32]: Switch to_fd to binary mode for the duration of this function, and then change back before returning. (start_job_command) [WINDOWS32]: Support output_sync mode on MS-Windows. Use a system-wide mutex instead of locking stdout/stderr. Call process_easy with two additional arguments: child->outfd and child->errfd. (exec_command) [WINDOWS32]: Pass two additional arguments, both -1, to process_easy, to adjust for the changed function signature. function.c (windows32_openpipe) [WINDOWS32]: This function now returns an int, which is -1 if it fails and zero otherwise. It also calls 'error' instead of 'fatal', to avoid exiting prematurely. (func_shell_base) [WINDOWS32]: Call perror_with_name if windows32_openpipe fails, now that it always returns. This avoids a compiler warning that error_prefix is not used in the MS-Windows build. config.h.W32.template (OUTPUT_SYNC): Define. build_w32.bat: Add w32/compat/posixfcn.c to compilation and linking commands. From Frank Heckenbach <f.heckenbach@fh-soft.de>: job.c (sync_output): Don't discard the output if acquire_semaphore fails; instead, dump the output unsynchronized.
2013-04-25Improve MS-Windows build scripts.Eli Zaretskii1-53/+93
build_w32.bat: Improve. Remove 'setlocal', as it isn't supported on Windows 9X. Add --help and usage instructions. Support both debug and optimized builds with GCC under --debug. If building out of Git repo, always produce config.h, and edit gmk-default.scm into gmk-default.h. w32/subproc/build.bat: Support debug and optimized builds with GCC.
2013-04-16Some cleanups for Windows builds after the output-sync option.Paul Smith1-3/+12
Note currently output-sync is not supported on Windows.

2012-01-28 Support a Windows build with Guile.Eli Zaretskii1-15/+71
README.W32.template: Update with instructions for building with Guile. build_w32.bat: Support building with Guile. make.h [HAVE_STDINT_H]: Include stdint.h.
2012-01-16Update copyright notices.Paul Smith1-1/+1
2012-01-15Add GNU Guile as an optional embedded scripting language for make.Paul Smith1-1/+8
On configure-enabled systems, configure will detect Guile installed (using pkg-config, which is how GNU Guile is distributed) and enable it if so. On all non-configure-enabled systems, currently, the default is for Guile support to be disabled.

* dir.c: WIN32 does not support inode. 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 WIN32 right now so it is lumped under port #ifdef WIN32. * function.c: WIN32: call subproc library (CreateProcess()) instead of fork/exec. * job.c: WIN32: Added the code to do fork/exec/waitpid style processing on WIN32 systems via calls to subproc library. * main.c: WIN32: 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: WIN32: A few macros and header files for WIN32 support. * misc.c: WIN32: Added a function end_of_token_w32() to assist in parsing code in read.c. * read.c: WIN32: Fixes similar to MSDOS which allow colon to appear in filenames. Use of colon in filenames would otherwise confuse make. * remake.c: WIN32: Added include of io.h to eliminate compiler warnings. Added some code to default LIBDIR if it is not set on WIN32. * variable.c: WIN32: 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: WIN32: Added detection for filenames containing forward or backward slashes. * NMakefile: WIN32: Visual C compatible makefile for use with nmake. Use this to build GNU make the first time on Windows NT or Windows 95. * README.WIN32: WIN32: Contains some helpful notes. * build_w32.bat: WIN32: If you don't like nmake, use this the first time you build GNU make on Windows NT or Windows 95. * config.h.WIN32: WIN32 version of config.h * subproc.bat: WIN32: 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: WIN32: opendir, readdir, closedir, etc. * w32/include/pathstuff.h: WIN32: used by files needed functions defined in pathstuff.c (prototypes). * w32/include/sub_proc.h: WIN32: prototypes for subproc.lib functions. * w32/include/w32err.h: WIN32: prototypes for w32err.c. * w32/pathstuff.c: WIN32: File and Path/Path conversion functions. * w32/subproc/build.bat: WIN32: build script for subproc library if you don't wish to use nmake. * w32/subproc/NMakefile: WIN32: Visual C compatible makefile for use with nmake. Used to build subproc library. * w32/subproc/misc.c: WIN32: subproc library support code * w32/subproc/proc.h: WIN32: subproc library support code * w32/subproc/sub_proc.c: WIN32: subproc library source code * w32/subproc/w32err.c: WIN32: subproc library support code
