changelog

这是一个自动生成MAKEFILE的工具。一个很有用的库。在LINUX工程项目里是很好的帮手。希望对大家有点帮助。

	* libtool.m4: Support $host_os as /sysv5uw7*/ from newer
	config.guess in addition to older /unixware*/.  Use compiler
	driver, not linker, for linking shared libraries.

2001-04-24  Gary V. Vaughan  <[e-mail]>

	* libtool.m4, ltmain.in, libltdl/configure.in,
	tests/quote.test:  Remove stale references to ltconfig.

	* ltdl.m4 (AC_C_INLINE): No longer required.
	* libltdl/ltdl.c (strdup, strcmp, strchr, strrchr, memcpy, trim,
	free_vars):  Revoke inline keyword from declarations.  `static
	inline' is not very portable, and in addition Unixware 7.1.1's
	compiler says you can't access static variables from inline
	functions.
	Reported by Peter Eisentraut  <[e-mail]>

2001-04-24 Albert Chin-A-Young <[e-mail]>

	* libtool.m4: Handle case where /bin/nm -p outputs multiple
	symbol types (like under HP-UX 11.00).

2001-04-24  Thomas Tanner  <[e-mail]>

	* TODO: describe problems with libltdl
	* ltmain.in (ILD): tidy up, add comments, remove dead code,
	  merge duplicate code
	* ltmain.in (ILD): don't touch newdependency_libs after scan or
	  dlopen pass
	* ltmain.in (ILD): don't dlpreopen dependency_libs of a dlopened
	  module (remove absolutely wrong quick hack)
	* ltmain.in (ILD): remove wrong comments about duplicate removal
	* ltmain.in (ILD): build a static-only module if it has
	  static libraries in its dependencies (so that libltdl can
	  safely load dependency_libs)
	* ltmain.in (argument parsing): prefix comparsions of -l args with X,
	  replace -lc with `-framework System' _after_ the ILD passes
	* ltmain.in (argument parsing): support dl[pre]open
	  for both .o and .lo files
	* ltmain.in (deplibs_check): use portable test syntax
	* ltmain.in (help): document -prefer-[non-]pic flags
	* ltmain.in: improve readablity by adding some comments,
	  rename uninst_* to notinst_* (more adequate name)

2001-04-24  Gary V. Vaughan  <[e-mail]>

	* doc/PLATFORMS:  More updates from subscribers to
	[e-mail].

	From Tim Mooney <[e-mail]>
	* tests/Makefile.am (TESTS_ENVIRONMENT): Make sure the *.test
	scripts get the same make that was used in the top level
	directory.

2001-04-23  Gary V. Vaughan  <[e-mail]>

	* doc/PLATFORMS:  Updated with more platforms successfully
	tested by members of [e-mail].

2001-04-23  Peter Eisentraut  <[e-mail]>

	* doc/PLATFORMS:  With this patch, freebsd4.3 passes the test
	suite.
	* libltdl/ltdl.c (lt_dlexit): Quit loop if only resident modules
	are left.

2001-04-23  Gary V. Vaughan  <[e-mail]>

	* doc/PLATFORMS:  With this patch, my Solaris boxes now pass the
	test suite,  Yay!
	From Albert Chin-A-Young <[e-mail]>
	* ltmain.in:  `test -L' is not portable, and infact breaks uninstall
	mode on Solaris.  Fallback to `test -h' and finally `test -f',
	but be careful not to let the failure status cause libtool to
	stop.

	From Simon Spero <[e-mail]>
	* ltdl.m4 (AC_LTDL_DLSYM_USCORE):  Add $LIBADD_DL while
	checking for dlsym _.

	From Simon Spero <[e-mail]>
	* libtool.m4 (lt_cv_deplibs_check_method) [darwin]: Set it!

	* TODO: Make a note to undo this later.
	From Christoph Pfisterer <[e-mail]>
	* libtool.m4: Use $() execution substitution quotation to work
	around zsh builtin echo \ escape removal.

2001-04-22  Peter Eisentraut  <[e-mail]>

	* bootstrap: Allow overriding the location aclocal, automake,
	autoconf, autoheader from the environment.

	* demo/Makefile.am: Automake 1.4e does not allow `+=' assignments
	if the variable was not set with `=' earlier.  `+=' was not useful
	here anyway.

2001-04-22  Gary V. Vaughan  <[e-mail]>

	* ltdl.m4 (AC_CHECK_HEADERS): UW7 has sys/dl.h, so we must
	check for that here.
	* libltdl/ltdl.c (HAVE_SYS_DL_H):  Include it if necessary for
	the dlopen loader.
	Reported by Matthew Schalit <[e-mail]>

	* libtool.m4 (AC_DEPLIBS_CHECK_METHOD):  Use pass_all for
	various releases of UnixWare and OpenServer that support it.
	Reported by Matthew Schalit <[e-mail]>

	* doc/PLATFORMS:  Updated with various platforms successfully
	tested by members of [e-mail].

2001-04-21  Gary V. Vaughan  <[e-mail]>

	* TODO:  propose pkg-config merge.

2001-04-21  Nick Hudson  <[e-mail]>

	* ltmain.in: Correct an error in yesterday's patch.

2001-04-20  Nick Hudson  <[e-mail]>

	* libtool.m4: Improve NetBSD support.
	* ltmain.in: ditto.

2001-04-19  Dan McNichol <[e-mail]>

	* libtool.m4: Build standard shared libraries on AIX POWER
	more like AIX does, with a shared object archived into lib<xxx>.a.
	On AIX -bexpall flag does strange things... Don't use it.
	Fix quotes around -berok flag.  Add support for AIX 5.
	Add support for run time linking on AIX POWER. (should work
	on AIX 4.2 and up).  Turn this feature on by adding -brtl flag
	to LD_FLAGS.  Add support for AIX on IA64. Note: AIX on IA64
	uses a SYSV type linker.  Add a comment telling what to do if the
	TOC starts getting too large on AIX.
	* NEWS: mention aix5 support.

2001-04-18  Alexandre Oliva  <[e-mail]>

	* TODO: Add -L- flag.

2001-04-11  Alexandre Oliva  <[e-mail]>

	* libtool.m4 (no_undefined_flag) [Solaris ld]: Change to -zdefs.

2001-04-11  Ossama Othman  <[e-mail]>

	* AUTHORS: Added myself to the list of maintainers.

2001-04-08  Gary V. Vaughan  <[e-mail]>

	* libtool.m4 (hardcode_libdir_flag_spec, osf4/osf5): Use ${wl}
	to pass -rpath when compiling with gcc.
	Reported by Tim Mooney <[e-mail]>

	* libltdl/ltdl.c (sys_shl_open): Cache a handle for the `self'
	module, since HPUX adds module symbols into the `self' pool if
	it is opened later.  Return the cached pointer if the caller
	subsequently tries to open `self'.
	(sys_shl_sym): Diagnose NULL modules.

	From Peter Eisentraut  <[e-mail]>
	* ltmain.in (clean,uninstall): test -e is not portable.  Well,
	neither is -L, but I'm hoping that redirecting error messages
	to /dev/null and relying on non-zero exit status will work okay
	on the few hosts that don't support -L.

2001-04-08  Nick Hudson  <[e-mail]>

	* ltmain.in: Improve check for valid -version-info parameter.

2001-04-08  Gary V. Vaughan  <[e-mail]>

	From Nick Hudson  <[e-mail]>
	* doc/Makefile.am (libtool_TEXINFOS): Add fdl.texi so that it
	is included in the distribution.

2001-04-07  Peter Eisentraut  <[e-mail]>

	* ltmain.in (clean,uninstall): Do not error if the file doesn't
	exist and 'rm -f' was used.  Exit with status 1 on error.

2001-04-06  Nick Hudson  <[e-mail]>

	* ltmain.in: Implement a new deplibs_check_method called
	match_pattern that does pattern matching on filenames...
	* libtool.m4: ...use it with NetBSD

2001-04-05  Gary V. Vaughan  <[e-mail]>

	* doc/libtool.texi (Multiple dependencies): A note about the
	problems I've reintroduced by reverting the my patch of 2001-03-31.

	From Edward Lee <[e-mail]>
	* libtool.m4: Typos.

	* tests/Makefile.am (TESTS): Delete references to depdemo-dups.test.
	* tests/depdemo-dups.test:  Removed, as part of the patch
	reversion below.
	* ltmain.in: Revert my change from 2001-03-31.  Although it
	was technically correct, it opens a whole can of worms we don't
	want to deal with right now.

	From Ahmed Masud <[e-mail]>
	* libltdl/ltdl.c (sys_shl_open):  Return a NULL module handle
	for self opening.
	(sys_shl_close):  Be careful not to close a NULL module handle.
	(sys_shl_sym):  Allow shl_findsym() to open NULL modules, but
	discard the modified module address it returns.

	* libltdl/ltdl.c (lt_dlopen):  When reading the .la file,
	reallocate the line buffer size if the line overflows the
	original buffer.
	Reported by Nick Hudson <[e-mail]>

	* NEWS (1.3d) Removed bogus ltconfig reference.

2001-04-03  Gary V. Vaughan  <[e-mail]>

	* libtool.m4 (_LT_AC_LTCONFIG_HACK):  Remove the spurious
	`dnl' from the help text of --with-pic.
	Reported by stefan <[e-mail]>

2001-04-02  Gary V. Vaughan  <[e-mail]>

	* configure.in: bumped version to 1.3e.

	GNU libtool 1.3d was released.

	* NEWS: inserted todays date.

2001-04-01  Christoph Pfisterer  <[e-mail]>

	* libtool.m4: Fixed support for Darwin and Rhapsody. Now correctly
	hardcodes the library path and adds versioning. Other small
	fixes.
	* ltmain.in: Fixed special cases for libc and libm on Rhapsody and
	Darwin. One of them was misplaced. Added version_type case for
	Rhapsody and Darwin, named "darwin".

2001-03-31  Gary V. Vaughan  <[e-mail]>

	* ltmain.in: Remove the code for stripping duplicate deplibs
	from libtool link lines -- duplicates are somtimes necessary
	to satisfy inter-library dependencies, and never cause link to
	fail even if they are spurious.
	* tests/depdemo-dups.test: New file.  Make sure this bug doesn't
	creep back in again!
	* tests/Makefile.am (TESTS): Use the new test above.

2001-03-29  Edward M. Lee  <[e-mail]>

	* libtoolize.in: Check configure.ac and prefer configure.ac to
	configure.in.

	* libtoolize.in: change recommendation from AM_PROG_LIBTOOL to
	AC_PROG_LIBTOOL.

	* libtool.m4: Generate dll/import libraries for cygwin according
	to the following: libFOO.a (static lib), libFOO.dll.a (import
	lib), cygFOO-version.dll (dll).  Update postinstall_cmds and
	postuninstall_cmds to reflect this.
	* ltmain.in: Generate installed .la files with dlnames set to
	../bin/cygFOO-version.dll for normal dlls. dlls for modules
	remain with the .la file.

	* libltdl/ltdl.c:  Use windows paths while calling LoadLibrary.

2001-03-16  Albert Chin  <[e-mail]>

	* libtool.m4 (save_CPPFLAGS): Fix typo.

2001-03-13  Alexandre Oliva  <[e-mail]>

	* libtool.m4 (lt_cv_compiler_c_o): Cache it.
	(lt_cv_compiler_o_lo): Likewise.

2001-03-09  Peter Eisentraut  <[e-mail]>

	* ltmain.in (clean): Automatically remove $objdir (usually '.libs').

2001-03-08  Gary V. Vaughan  <[e-mail]>

	* ltconfig.in (library_names_spec): Undo latin-1 spaces I pasted
	in yesterday by mistake.

2001-03-07  Gary V. Vaughan  <[e-mail]>

	From Tor Lillqvist <[e-mail]>
	* libtool.m4 (export_symbols): On Windows, if the export_symbols
	file (which has been passed to libtool with the -export-symbols
	command line switch) already is a .def file, use it as is.

	* libtool.m4 (library_names_spec): Using m4 quotes correctly this
	time around!

	From Tor Lillqvist <[e-mail]>
	* libtool.m4 (library_names_spec): Use an appropriate filename
	prefix for dlls -- lib for mingw; cyg for cygwin; pw for pw32.

2001-03-06  Alexandre Oliva  <[e-mail]>

	* libtool.m4 (can_build_shared) [AIX 4.[01], GCC]: GCC up to
	2.96 can't build shared libraries reliably.  Disable them.

	* ltmain.in: When dropping dependencies of a -no-undefined
	library, give up on building a shared library.

2001-03-05  Akim Demaille  <[e-mail]>

	* ltmain.sh: Don't quote the argument of case/esac and
	assignments.
	* libtool.m4: Likewise.

2001-03-03  Markus F.X.J. Oberhumer <[e-mail]>,
	    Alexandre Oliva <[e-mail]>

	* libtool.m4: Added explicit return type to all C functions.

2001-02-22  Gary Vaughan  <[e-mail]>

2001-02-20  Gary Vaughan  <[e-mail]>

	* libltdl/ltdl.c (lt_dlcaller_register): dont set an unsigned
	type to a negative number.
	Reported by Guenter Millahn <[e-mail]>

2001-02-05  Gary V. Vaughan  <[e-mail]>

	From Nick Hudson <[e-mail]>
	* ltdl.m4 (AC_LTDL_SYS_DLOPEN_DEPLIBS): netbsd* is able to
	automatically load module deplibs without assistance from
	libltdl.

2001-02-02  Gary V. Vaughan  <[e-mail]>

	* libltdl/ltdl.c (load_deplibs): Make sure the depcount is reset,
	even when deplibs are not used because of the patch below.

	* ltdl.m4 (AC_LTDL_SYS_DLOPEN_DEPLIBS): If we know that the host
	architecture automatically loads deplibs, then...
	* libltdl/ltdl.c (load_deplibs): ...don't manually load each one.

	* TODO:  Updated.

	* libltdl/ltdl.c (load_deplibs): If loading a deplib fails,
	don't sweat -- it may be a lib that is already statically linked
	into the loading application.
