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.

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.

need a library prefix like 'lib', such as BeOS. Fix a number
of bugs exposed by this test in order for it to pass.
Currently the prefix is hardcoded as 'lib', as I am not aware
of systems that require a different prefix:
* libltdl/loaders/preopen.c (lt_dlpreload_open): Move error
condition out of test loop to be sure that each originator is
tried, instead of erroring out if the first doesn't match.
Support passing NULL as the originator to load all preloaded
modules originating in the program itself.
* libltdl/lt_dlloader.c (lt_dlloader_dump): New debug function.
* libltdl/libltdl/lt_dlloader.h (lt_dlloader_dump): Declare it
when LT_DEBUG_LOADERS is defined at compile time.
* libltdl/ltdl.c (lt_dlinit): Dump loader list after successful
initialisation.
(tryall_dlopen): Add a new VTABLE parameter to force use of a
specific loader in preference to trying every loader in turn.
Adjust all callers.
(try_dlopen): Always see whether a module was preloaded for
module names with no directory component before searching the
filesystem for a match.
* libltdl/m4/libtool.m4 (_LT_CMD_GLOBAL_SYMBOLS): Declare
a new global_symbol_to_c_name_address_lib_prefix variable.
(global_symbol_to_c_name_address_lib_prefix): The sed
expressions to use when a lib prefix is enforced need to be
slightly different to work with preloaded modules.
* libltdl/config/ltmain.m4sh (func_generate_dlsyms): In order
to name preloaded symbols correctly for the lookup algorithm
to work when the loaded module file must be prefixed with lib.
Use global_symbol_to_c_name_address_lib_prefix when
need_lib_prefix is other than no.
* tests/need_lib_prefix.at: New test to check for breakage on
hosts where need_lib_prefix is unknown.
* Makefile.am (TESTSUITE_AT): Add new test.
* tests/TODO: Note missing tests that would have caught some
of the latent bugs fixed by this patch.
* HACKING: Document libltdl keyword.
* NEWS: Updated.

* libltdl/m4/argz.m4 (gl_FUNC_ARGZ): add new test to check
if $host's argz facilities are known bad. Err on the side
of caution if cross-compiling.

For creating a linker input filelist due to long cmdline,
extract the first object if `compiler_needs_object' is yes.
