(_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,

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.

Here, we add lt_dlopenadvise() to allow callers to request,
among other things, local or global symbol visibility from the
underlying dlloader:
* libltdl/ltdl.c (LT_DLRESIDENT_FLAG): Removed.
(LT_DLIS_RESIDENT): Use public is_resident info field.
(LT_DLIS_SYMLOCAL, LT_DLIS_SYMGLOBAL): New macros to test for
module symbol visibility status.
(tryall_dlopen): If vtable->module_open() was able to act on
either is_symlocal or is_symglobal hints, store that in
the handle flags.
(lt_dlopenadvise): New function that works like lt_dlopen(),
but accepts an advise type to determine whether to ask
dlloaders to change default symbol visibility.
(lt_dlopen, lt_dlopenext): Just call lt_dlopenadvise() with
the correct parameters.
(lt_dladvise_init, lt_dladvise_destroy): New functions to
initialize and destroy an advise type hint.
(lt_dladvise_ext, lt_dladvise_resident, lt_dladvise_local)
(lt_dladvise_global): Set hints on an advise type.
(openadvise): Factored out of lt_dlopenadvise.
(has_library_ext): Factored out of lt_dlopenadvise.

(lt_dlinfo): New fields for advise hints.
* libltdl/libltdl/lt_dlloader.h (lt_module_open): Add a new
advise parameter. Adjust all callers.
(lt_dladvise): New opaque type for advise hints.
* libltdl/libltdl/lt__private.h (lt__advise): Declare

define these symbols if the system has equivalents.
(vmopen): If unable to act on a caller request to set symbol
visibility, then unset the relevant hints in the advise type.

(LTDL_SUBDIR_LIBOBJS): ...to this.
* configure.ac: Adjust.
* doc/libtool.texi (Invoking libtoolize): Document the new modes

(func_scan_files): If --subproject, --recursive or --nonrecursive

(LT_CONFIG_LTDL_DIR): New macro to centralise setting the

defer to LT_CONFIG_LTDL_DIR.
(AC_LIBLTDL_CONVENIENCE): Adjust to upgrade to the new style.
(LTDL_INSTALLABLE, AC_LIBLTDL_INSTALLABLE): Ditto.
(LTDL_INIT): lt_ltdl_dir is set by LT_CONFIG_LTDL_DIR now, and
even `./' needs trailing slashes trimming! If the user didn't
upgrade their configure.ac yet, call LT_CONFIG_LTDL_DIR for them.
* libtoolize.m4sh (func_scan_files): If --ltdl option is given

installation to the libtoolize master tree, so that libltdl is
useable even in the extreme case of when automake and autoconf are
not installed on the developers machine. Part of this change
requires some duplication of rules between Makefile.am (which
builds libltdl for this distribution) and libltdl/Makefile.am
(which is used by projects that libltoolize --ltdl --copy), so
libtool now really does use a single toplevel Makefile.am, and we
generate libltdl/Makefile.am from that:
* m4, config: Moved from here...
* libltdl/m4, libltdl/config: ...to here, to reduce the amount of
kludging needed in bootstrap for autoreconf to run.

tests/fcdemo/Makefile.am, tests/mdemo/Makefile.am,

* libltdl/m4/ltdl.m4: Increment serial number.
(LTDL_INIT): Accept an optional directory argument to prefix each
of the LD_DLLOADERS locations. Default to empty for backwards
compatibility.
* Makefile.maint: Adjust to compensate.
* configure.ac (AC_CONFIG_AUX_DIR, AC_CONFIG_MACRO_DIR): Adjust.
(AC_CONFIG_LIBOBJ_DIR): Set here so that we can build LTLIBOBJS
from in a subdirectory from the amalgamated Makefile.am.
(AM_PROG_CC_C_O, AM_INIT_AUTOMAKE): Use subdir-objects.
(AC_CONFIG_FILES): Remove libltdl/Makefile.am.

the merged rules, and tweaking paths to accomodate the difference
in directory from Makefile.am to libltdl/Makefile.am.

timestamps...
(install-data-hook): ...and set execute bit as appropriate.
(uninstall-hook): Not forgetting to remove them at uninstall.
(libltdl/Makefile.in): New rule. Called from...
* bootstrap: ...here to avoid relying on config.status at
bootstrap time.
(auxdir, m4dir): Extract from configure.ac for ease of future
maintenance. Adjust all references.
(reconfdirs): Call autoreconf for libltdl too -- even
though we don't use it for the build, libltdl/configure and
friends are installed with `libtoolize --ltdl --copy'.
* libtoolize.m4sh: Add files from the installed config master tree
to libtoolize --ltdl project subdirectory.
Diagnose duplicated files when --ltdl is used in an autotooled
project.
It's perfectly fine to run `libtoolize --ltdl --copy' in a tree
that has no configure.ac or configure.in; we want libltdl to be
useful even to projects that don't use autotools themselves.
(libtoolize_flags): Removed. Changed all callers.
(func_massage_pkgconfig_files): New function.
* tests/standalone.at: New tests for using libltdl without
supporting configury in the parent project.

(pkgdatadir, nobase_dist_pkgdata_DATA, aclocalfiles): ...these
respectively.
(edit): Adjust for new variable names.
(install-data-local): Don't bother to remove old macro files that
will be overwritten by the installation, and perform a manual
installation of $(aclocalfiles) to preserve timestamps.
(install-exec-hook): Removed. No need to make versioned links.
(uninstall-hook): No need to remove versioned links, but now we
need to manually remove the manually installed $(aclocalfiles).
* doc/libtool.texi: Remove bogus notes about setting
ACLOCAL_AMFLAGS for versioned libtool installations.
* NEWS: Remove parallel installation item.
* Makefile.am, Makefile.maint: .. install, update it.
* NEWS, doc/libtool.texi (Distributing): .. document it.

Makefile.am.
* tests/testsuite.at: New container for Autotest test groups.
* tests/am-subdir.at: New test group for compatibility with

Without this change, the distributed libtool tarball has a

* tests/defs (func_mkdir_p): Ditto.
