changelog

GNU libtool 是一个通用库支持脚本

	* libtool.m4 (AC_LIBTOOL_DLOPEN_SELF)
	(AC_LIBTOOL_PROG_COMPILER_PIC): Make sure `$wl' is properly
	expanded for tests involving `export_dynamic_flag_spec',
	`lt_prog_compiler_static'.

2005-11-11  Ralf Wildenhues <[e-mail]>

	* libtool.m4 (AC_LIBTOOL_SYS_DYNAMIC_LINKER) [ freebsd ]:
	Fix shlibpath_overrides_runpath settings.
	Reported by Dave Benson <[e-mail]>.

2005-11-10  Charles Wilson  <[e-mail]>

	* ltmain.in (func_win32_libid): use $SED not sed.

2005-11-10  Albert Chin-A-Young  <[e-mail]>

	* libtool.m4 (AC_LIBTOOL_LANG_CXX_CONFIG) [ hpux10, hpux11 ]
	<hppa*64,ia64, aCC,g++>:
	Use C++ compiler for linking rather than ld.

2005-11-09  Ralf Wildenhues <[e-mail]>

	* libtool.m4 (AC_LIBTOOL_PROG_LD_SHLIBS): Move setting of
	`variables_saved_for_relink'..
	(AC_LIBTOOL_SYS_DYNAMIC_LINKER): here, when both `shlibpath_var'
	and `runpath_var' have been set.
	Reported by Mike Frysinger <[e-mail]>.

	* libtool.m4 (AC_LIBTOOL_LANG_C_CONFIG): Move static_flag
	check..
	(AC_LIBTOOL_PROG_COMPILER_PIC): ..here, so that both
	`lt_prog_compiler_static' have actually been set, and the check
	is applied to each tag.

2005-11-07  Kean Johnston  <[e-mail]>

	* ltmain.in (link mode) [ sysv4*uw2*, unixware7* ]: Work around linker
	bug on older SCO systems.

2005-11-07  Albert Chin-A-Young  <[e-mail]>

	* libtool.m4 (AC_LIBTOOL_LANG_CXX_CONFIG)
	(AC_LIBTOOL_PROG_LD_SHLIBS) [ hpux10, hpux11 ]:
	hardcode_libdir_flag_spec and hardcode_minus_L are the same for
	hppa*64 and ia64*. Don't set
	hardcode_libdir_flag_spec='-L$libdir' on ia64* because if you
	specify +b and -L, +b overrides what is set into DT_RPATH.

2005-11-06  Ralf Wildenhues <[e-mail]>

	* libtool.m4 (_LT_AC_TRY_DLOPEN_SELF): lt_unknown is
	lt_dlunknown.

	* libtool.m4 (AC_LIBTOOL_LANG_C_CONFIG)
	(AC_LIBTOOL_LANG_CXX_CONFIG, AC_LIBTOOL_LANG_F77_CONFIG)
	(AC_LIBTOOL_LANG_GCJ_CONFIG):  Only call
	AC_LIBTOOL_SYS_LIB_STRIP and AC_LIBTOOL_DLOPEN_SELF in the C
	case, and without the tag argument.

	* libtool.m4: Fix comments.

2005-11-05  Kean Johnston  <[e-mail]>,
	    Ralf Wildenhues  <[e-mail]>

	* ltmain.in (link mode) [*-*-sco3.2v5*]: Don't pass through -lc,
	nor add it to deplibs.
	[*-*-sysv5*]: Ditto.
	[*-*-openbsd*, *-*-freebsd*, *-*-dragonfly*]: Remove bogus
	`$arg'.

2005-11-04  Ralf Wildenhues <[e-mail]>

	* THANKS: Updated.

2005-11-01  Ralf Wildenhues <[e-mail]>

	* libtool.m4 (_LT_AC_LOCK) [ solaris ]: Add `-64' to $LD if
	necessary, to permit combining of several convenience libs
	without any further objects added.
	Reported by Brian Barrett <[e-mail]>.

2005-11-01  Kean Johnston  <[e-mail]>,
	    Ralf Wildenhues  <[e-mail]>

	* libtool.m4 (AC_LIBTOOL_DLOPEN_SELF): Use
	`lt_prog_compile_static', not `link_static_flag'.  Expand `$wl'
	so expansion of `export_dynamic_flag_spec' works.
	(_LT_AC_TRY_DLOPEN_SELF): Show dlerror() in case of failure.
	(AC_LIBTOOL_PROG_LD_SHLIBS) [ aix3 ]: Likewise.
	(AC_LIBTOOL_PROG_COMPILER_PIC) [ hpux* ]: Use `${wl}'.

	dependency libraries when you dlopen a module.

2005-10-31  Albert Chin-A-Young  <[e-mail]>

	* libtool.m4 (AC_LIBTOOL_LANG_CXX_CONFIG)

	* ltmain.in (link mode): When accepting -64, -mips[0-9], et. al.
	compiler flags, don't set compiler_flags only for GCC as the
	vendor compiler also requires this flag. Sync with HEAD.
	Reported by Donald Anderson <[e-mail]>.

2005-09-21  Peter Ekberg  <[e-mail]>,

	* ltmain.in (clean mode): Clean up $dlname as well when cleaning
	an uninstalled libtool library. Fixes -mode=clean on Cygwin and
	MinGW to actually remove the dll when cleaning up an uninstalled
	library.

	* libtool.m4 (AC_LIBTOOL_PROG_LD_SHLIBS, AC_LIBTOOL_LANG_CXX_CONFIG):

	(AC_LIBTOOL_COMPILER_OPTION, AC_LIBTOOL_LINKER_OPTION)
	(AC_LIBTOOL_PROG_CC_C_O): When comparing expected and actual
	compiler/linker output for warnings, weed out both empty lines
	as well as lines starting with possibly indented `+', to allow
	for shell debugging with `set -x'.
	Check the weeded instead of unweeded contents for emptiness.

	* ltmain.in (link mode): Actually provide a useful error
	message.  Fixes long-standing shameful user neglection.
	Reported by Martin Paljak <[e-mail]>.

2005-09-08  Charles Wilson  <[e-mail]>

	* libtool.m4 (AC_LIBTOOL_LANG_CXX_CONFIG)

	* ltmain.in (install mode): Try "ln -s -f" and "rm -f && ln -s"
	to make a symlink for a shared library: the former is needed for
	libraries `ln' depends on, the latter for Solaris /bin/ln.
	Reported by Nelson H. F. Beebe <[e-mail]>.

	* ltmain.in: When a library is installed, dependent on a
	convenience library, and it involves relinking, the object
	files extracted from the convenience library are not removed
	after the relink. This is a problem if you build as non-root,
