I decided this feature was too impacting to make the permanent default
behavior. This set of changes makes the default behavior of make the
old behavior (no second expansion). If you want second expansion, you
must define the .SECONDEXPANSION: special target before the first target
that needs it.
This set of changes ONLY fixes explicit and static pattern rules to work
like this. Implicit rules still have second expansion enabled all the
time: I'll work on that next.
Note that there is still a backward-incompatibility: now to get the old
SysV behavior using $$@ etc. in the prerequisites list you need to set
.SECONDEXPANSION: as well.
check for this and exit with an error.
The closeout.c version from gnulib pulls in too much other stuff, and
gnulib requires an ANSI C 89 compliant compiler, while GNU make (so far)
still wants to work on K&R.
* New function: $(info ...)
* Disallow $(eval ...) to create prereq relationships inside command scripts
(caused core dumps)
* Try to allow more tests to succeed in Windows/DOS by sanitizing CRLF and \
* Various bug fixes and code cleanups (see the ChangeLog entry)
Implement a fix for bug # 2169: too many OSs, even major OSs like Solaris,
don't properly implement SA_RESTART: important system calls like stat() can
still fail when SA_RESTART is set. So, forget the BROKEN_RESTART config
check and get rid of atomic_stat() and atomic_readdir(), and implement
permanent wrappers for EINTR checking on various system calls (stat(),
fstat(), opendir(), and readdir() so far).
enable the automake ansi2knr capability.
Right now this doesn't quite build using a K&R compiler because of a
problem with the loadavg test program, but the rest of the code works. I'm
asking the automake list about this problem.
GNU make. Also he provides some other performance fixups after doing
some profiling of make on large makefiles.
Modify the test suite to allow the use of Valgrind to find memory problems.
New version of the manual, put into the doc subdir.
Enhancements: $(eval ...) and $(value ...) functions, various bug
fixes, etc. See the ChangeLog.
More to come.
properly.
Fix configure: allow cross-compilation; fix getloadavg (still needs _lots_
of work!)
Let $(call ...) functions to be self-referencing. Lets us do transitive
closures, for example.
* Update maintainers build process; remove GNUmakefile. Require builders to
run automake && autoreconf by hand.
* Use AC_SUBST_FILE to get the maintMakefile included, rather than GNU
make's include directive, which conflicts with automake 1.4's include
directive.
* 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
