[PATCH 00/12] Improve AIX support: libltdl, filename-based versioning.

Hi, here's a set of patches to fix the two major problems with current AIX support in libtool, that is: *) libltdl: lt_dlopen() does work /with/ runtime linking (LDFLAGS=-brtl) only. *) libtool: /Without/ runtime linking, there is "some" versioning support, but still far from being ideal for p

[PATCH 01/12] Support loading shared library archive members.

AIX supports shared objects as members of archive libraries, loadable with dlopen using the RTLD_MEMBER flag. * libltdl/ltdl.c: For AIX, define LT_SHARED_LIB_MEMBER to hold the parentheses used to identify the shared archive member. (lt_dlopenadvise) When LT_SHARED_LIB_MEMBER is defined, allow for

[PATCH 04/12] Specify shared member in soname_spec on AIX.

On AIX, without runtime linking, we create the shared object as member of the library archive. * m4/libtool.m4: (soname_spec) Specify the archive member when creating traditional lib.a shared archives on AIX. (archive_expsym_cmds) On AIX, split $soname into both the archive file name as well as the

[PATCH 11/12] No cross-library undefined symbols test on AIX.

While AIX does support undefined symbols in general, undefined symbols in one shared library do not trigger another shared library to be marked as needed by the linker. * tests/template.at: Skip test with undef syms across libraries on AIX. --- tests/template.at |6 +- 1 files changed, 5 i

[PATCH 06/12] Drop useless symlinks with AIX runtime linking.

On AIX, the standalone Shared Object we create when runtime linking is active does not support versioning at all, so the versioning symlinks are plain useless. * m4/libtool.m4: (library_names_spec) No versioning with AIX runtime linking. --- m4/libtool.m4 |4 ++-- 1 files changed, 2 insertions

[PATCH 08/12] Implement enable/disable aix-soname options.

Support filename-based shared library versioning on AIX with the lib.so library filename extension, which is used with runtime linking only. Runtime linking is enabled by the -brtl linker flag for executables and the -G linker flag for Shared Objects. (aix-soname=no): Default, also known as --disab

[PATCH 05/12] AIX runtime linking allows undef syms by default.

On AIX, when runtime linking is active, undefined symbols are allowd by default. Additionally, the '-G' linker flag needs to be specified before the '-bernotok' and any other user-defined linker flag, or '-G' would override some of them again. * m4/libtool.m4: (no_undefined_flag) Define for AIX run
