friends requires all libobjs to be in the same directory, as
declared by AC_CONFIG_LIBOBJ_DIR. That might prevent using
either recursive or nonrecursive libltdl if the parent project
has libobjs of its own, except that this patch tracks libltdl's
libobjs in another namespace:
* libltdl/m4/ltdl.m4 (_LT_LIBOBJ, _LT_LIBSOURCES): Versions of
AC_LIBOBJ and AC_LIBSOURCES that save missing sources in a
ltdl_LIBOBJS automake macro, instead of the global LIBOBJS
automake macro. Content of the macros inspired by code from
gnulib-tool.
(_LTDL_MODE_DISPATCH): Initialise lt_libobj_prefix in
nonrecursive mode.
(LTDL_INIT): Push and pop the new definitions around potential
sites that call AC_LIBOBJ. Also, using lt_libobj_prefix,
initialise ltdl_LIBOBJS and ltdl_LTLIBOBJS.
* libtoolize.m4sh (func_fixup_Makefile): Substitute ltdl_LIBOBJS
and ltdl_LTLIBOBJS for LIBOBJS and LTLIBOBJS during copying
either Makefile.am or Makefile.inc, depending on ltdl_mode.
Reported by Eric Blake <ebb9@byu.net>
sys_lib_dlsearch_path_spec): Allow for a cache variable
lt_cv_sys_lib_... to set these at configure time.
* doc/notes.texi: Short note about the above change.
* libltdl/m4/ltdl.m4 (_LTDL_CONVENIENCE, _LTDL_INSTALLABLE)
(LTDL_INIT): Set and substitute LTDLDEPS according to chosen
method.
* tests/configure-iface.at (installable libltdl)
(--with-ltdl-include/lib, --with-included-ltdl): Test it.
* doc/libtool.texi (Distributing libltdl): Document LTDLDEPS.
* NEWS: Updated.
Dependency bug exposed by Eric Blake in M4, found by Bob Proulx
build daemon.
LTDL_DLOPEN_SELF_WORKS, depending upon lt_cv_dlopen_self.
* libltdl/loaders/dlopen.c (vm_open) [!LTDL_DLOPEN_SELF_WORKS]:
Fail for dlopen(NULL), so that the preopen loader is used. This
fixes mdemo-exec.test failures on AIX where dlopen(NULL)
succeeds but dlsym resolves no symbol.
* NEWS: Update.
Report by Rainer Tammer.
dsymutil if it is available so that debugging is possible, check
for nmedit and dsymutil with AC_CHECK_TOOL, use the linker flag
-exported_symbols_list in preference to nmedit if it is available.
Drop support for xlc, it is probably broken.
* tests/template.at [darwin]: Skip this test, I can not find a way
to make it work on darwin9 with Xcode-3.0.
* NEWS: Note the dropping of xlc support.
LTDL_INIT. Accept (optional) new 'convenience' and 'installable'
options in lieu of LTDL_CONVENIENCE and LTDL_INSTALL macros. And
also, implement --with-included-ltdl, --with-ltdl-lib and
--with-ltdl-include configure-time options:
* libltdl/m4/ltoptions.m4: Associate existing option settings with
LT_INIT.
(LT_OPTION_DEFINE): Associate options 'nonrecursive', 'recursive',
'subproject', 'installable' and 'convenience' with LTDL_INIT.
(_LT_MANGLE_OPTION, _LT_SET_OPTION, _LT_IF_OPTION)
(_LT_UNLESS_OPTIONS, _LT_SET_OPTIONS): Add MACRO-NAME argument to
support options to named macros instead of hardcoding only LT_INIT
options.
* libltdl/m4/ltdl.m4 (_LTDL_CONVENIENCE): Factor common code from
LTDL_CONVENIENCE and LTDL_INIT([convenience]).
(_LTDL_INSTALLABLE): Factor out common code from LTDL_INSTALLABLE
and LTDL_INIT([installable]).
(_LTDL_SETUP): Renamed from LTDL_INIT. Support new configure-time
options: --with-included-ltdl, --with-ltdl-lib,
--with-ltdl-include.
(LTDL_CONVENIENCE, LTDL_INSTALLABLE): Adjust.
(LT_WITH_LTDL): Removed.
(LTDL_INIT): Parse caller options.
* libltdl/m4/libtool.m4 (LT_INIT): Declare that this macro must be
expanded before LTDL_INIT, and be sure to parse caller options.
* configure.ac: Call directly into internal _LTDL_SETUP macro.
* libtoolize.m4sh (func_scan_files): Ltdl mode argument moved from
LT_CONFIG_LTDL_DIR to LT_INIT.
* tests/nonrecursive.at, tests/recursive.at: Use new interfaces.
* tests/configure-iface.at: Test it.
* Makefile.am (TESTSUITE_AT): Add configure-iface.at.
* doc/libtool.texi (Distributing libltdl): Document improved.
LTDL_INIT interfaces.
* NEWS: Updated.
* libltdl/m4/ltdl.m4 (_LT_BUILD_PREFIX): New macro.
If the Autoconf version used is >= 2.62, then expand to
`${top_build_prefix}', otherwise to `${top_builddir}/'.
(LTDL_CONVENIENCE, LTDL_INSTALLABLE): Use it for defining
LIBLTDL. Fixes a build failure with AIX make in a package
using convenience libltdl in nonrecursive mode.
* doc/libtool.texi (Distributing libltdl): Document requirements
to define `top_build_prefix' if Automake is not used.
Report by Bob Friesenhahn.
* libltdl/m4/libtool.m4 (_LT_LINKER_BOILERPLATE)
(_LT_LINKER_OPTION, _LT_CMD_GLOBAL_SYMBOLS): Remove
conftest.dSYM directory.
Report and analysis by Jeff Squyres and Peter O'Gorman.
(_LT_LANG_CXX_CONFIG) [ linux ]: Add support for IBM XL 8.0
C/C++ (xlc*, xlC*) and IBM XL Fortran 10.1 (xlf*) on GNU/Linux,
tested on ppc, pending a $shlibpath_var related fix.
(_LT_SYS_HIDDEN_LIBDEPS): Double-quote $output_verbose_link_cmd
properly during evaluation, obsoleting $no_glob_subst mangling.
* NEWS: Update.
New function.
(func_dirname_and_basename) <!XSI>: New function.
* libltdl/config/ltmain.m4sh (func_ltwrapper_scriptname):
Call it. Also, take advantage of missed optimization using
func_dirname's additional arguments.
(func_mode_compile): Call it.
(func_mode_install): Call it.
(func_mode_link): Call it.
force-pull in this file by aclocal.
* libltdl/m4/libtool.m4 (LT_INIT): Require LTOBSOLETE_VERSION.
* tests/libtoolize.at (upgrading verbatim style aclocal.m4):
Adjust.
