dependency libraries from dlpreopened modules to libraries:
* config/ltmain.in: Support new -weak link mode option. Adjust
help message.
* libltdl/Makefile.am (libltdlc_la_LDFLAGS): Use it.
* doc/libtool.texi (Linking with dlopened modules): Document it.

complaint now, and recently a few more have crept in. Make a
start at refactoring the code with shell functions, and
standardising on option parsing style:
* config/ltmain.in (func_echo, func_verbose, func_error)
(func_fatal_error, func_fatal_help, func_missing_arg)
(func_version, func_usage, func_help): Boiler plate shell
functions mostly copied from libtoolize.in. Changed *lots* of
shell snippets to call these functions as appropriate, rather than
inlining the same code over and over.
(func_config, func_features, func_enable_tag, func_mode_help):
Factored out from the shared option parsing loop. Write a new
shared option parser based on the one in libtoolize.in.
(func_check_version_match): Factored out from global scope.
(func_mode_compile, func_mode_execute, func_mode_finish)
(func_mode_install, func_mode_link, func_mode_uninstall): Break
each of the top level mode handlers out into a function. Adjust
main loop.
(modename, prevopt, prev, optarg, show_help): Removed in the
course of cleaning up the shared option parser.
(opt_duplicate_deps): Use `:' and `false' instead of `yes' and `',
so we can run it directly, rather than calling test.
instructions, and provide additional useful info alongside the bug
reporting address in --help output:
* Makefile.am (edit): Substitute $host_triplet.
* libtoolize.in: Output useful debug info with --help.
* config/ltmain.in: Ditto.
* README: Rewritten. Added copyright info.
* README-alpha: Rewritten. Added copyright info.
* HACKING: New file, partly taken from old README-alpha.
distributed files (m4/ltversion.m4 and config/ltmain.in) in the
readonly source tree:
* Makefile.am (stamp-vcl): Keep only one copy of stamp-vcl; in
$(top_srcdir), so that an up-to-date version is rolled into the
dist tarball even from a VPATH build.
($(top_srcdir)/config/ltmain.sh): Don't depend on Makefile,
otherwise ltmain.sh needs to be rebuilt after every config.status
run, and then configure needs to be rebuilt, and it all goes
horribly wrong :-/ Unfortunately, we can't depend on Makefile.am
either, because that is a circular dependency. The downside of
this change is that it is now possible to edit Makefile.am to
change the way ltmain.sh is generated, and the dependency
information can't tell that ltmain.sh needs regenerating.
the many and varied m4 symbols accumulated by libtool over the
years, considering also that modern autoconf can detect unexpanded
macros even without AC in the macro name:
* bootstrap: Remove libltdl/config.h from previous releases.
* m4/libtool.m4, m4/ltdl.m4, doc/libtool.texi: Basically, run a
giant sed transformation like this:

Makefile.
(timestamp): Factor out timestamp setting and edit it based on the
version number, so that it is empty for release versions.
($(top_srcdir)/config/ltmain.sh): Use it.
(libtoolize): Ditto.
`cd $(top_srcdir)' for this rule, we can't mv ltversion.tmp to the
relative $(top_srcdir) again! Also, run $(MKSTAMP) before changing
directories, or it won't be found.
($(top_srcdir)/config/ltmain.sh): Ditto.
(EXTRA_DIST): We should distribute ltversion.m4 too.
not actually be set, we should use SHELL here, also make darn sure
that SHELL is set to something. Bug from Willem Jan Palenstijn
<wpalenst@math.leidenuniv.nl>.
the installed libltdl sources for libtoolize need to put
libltdl/configure.ac in the parent package so that *it* can
subconfigure libltdl. That way we don't put any constraints on
the build system used by the parent package because the
libtoolized libltdl subtree is a self-contained sub-project:
* libltdl/Makefile.am (EXTRA_DIST): Add configure.ac.
(nobase_ltdldata_DATA): Change back to libltdl's own
configure.ac.
required to write this changeset -- especially that ltmain.sh is
the same on any machine for a given release, which I hadn't
noticed for some bizarre reason: It turns out that generating
distributed files from configure causes no end of hassle, as
evidenced by the many patches I've generated over the last few
days to try and get the dist and distcheck make rules to work.
Instead of all that hair, we now simply generate our distributed
files (now including ltmain.sh) with make rules -- and since
automake creates make variables for all AC_SUBSTs, that is really
easy. The code looks a lot more like automake and autoconf
Makefile.ams now, and doesn't have all the rough edges the earlier
hacky solution suffered from. We still generate libtool from
config.status, but that is not a distributed file, and doesn't
break the golden rule. Besides, there is way more going on there
than a bunch of substitutions:
* Makefile.am (edit): New common sed substitutions for files now
generated by make instead of config.status.
(CLEANFILES): Clean new tmp files.
(EXTRA_DIST): Add ltmain.sh.
(vcl-tmp): Reinstated.
(m4/ltversion.m4, config/ltmain.sh): New rules. Generate from
here instead of config.status.
(libtoolize): Ditto.
(libtool): Call config.status to regenerate if necessary.
(dist-hook): Removed.
* config/ltmain.in: Moved here from top_srcdir.
* README-alpha: Update instructions to check AS_SHELL_SANITIZE is
up to date.
* bootstrap: Rewritten. Generate m4/ltversion.m4 and
config/ltmain.sh because configure depends on them.
* configure.ac (AC_CONFIG_SRCDIR): Use libtoolize.in now that
ltmain.in has moved.
(AC_CONFIG_FILES): Don't generate distributed files,
config/ltmain.sh and libtoolize from config.status. We have make
rules to do that now.
help `make distcheck'; not only do we have to make a copy of
ltmain.sh available in the source tree, but we have to be really
careful about permission bit twiddling when we copy it across into
the possible read-only $(top_srcdir)/config directory!
quite rightly for every project except libtool, that there will be
an ltmain.sh in the source tree.
(EXTRA_DIST): As do the dist rules it generates.
(dist-hook): Even though we definitely don't want to distribute
our local ltmain.sh.
the generated m4/ltversion.m4. Except for CVS revisions:
* ltmain.in (package_revision): Don't try to deduce it from
TIMESTAMP, since that is empty for release versions; simply
substitute it...
* configure.ac (package_revision): ...from here, having
precalculated it before resetting TIMESTAMP for release versions.
* bootstrap: Force regeneration of m4/ltversion.m4, but retain
timestamps if there is no change to the content.
CVS autoconf, otherwise pdksh chokes on some nested escaped quotes
from libtool.m4. Using CVS autoconf protects configure from
non-bourne compatible shells in the same way this changeset
protects libtool and libtoolize:
* libtoolize.in: Include latest CVS autoconf AS_SHELL_SANITIZE
expansion to make various shells fully bourne compatible.
* ltmain.in: Ditto.
* m4/libtool.m4 (AC_PATH_TOOL_PREFIX): Remove spurious quotes, the
RHS of = assignment is not IFS split.
(_LT_LANG_CXX_CONFIG): Ditto.
(AC_LIBTOOL_POSTDEP_PREDEP): Ditto.
target forced a rebuild of stamp-vcl in the build tree (and
hence regeneration of m4/ltversion.m4, thus an automake driven
rebootstrap that doesn't know about $fakes) requiring a fresh
./bootstrap after every cvs/tla update:
* Makefile.am (vcl.tmp): Removed.
(stamp-vcl): Adopt former vcl.tmp target rules.
on darwin can not be extracted using ar, we need to use lipo to
extract the thin archives and then use lipo again to generate the
individual fat objects. This should allow people to run configure
with CC set to "cc -arch ppc -arch ppc64" or "cc -arch ppc -arch
i386" or whatever to match the toolchain they have available.
lt__handle to better reflect the naming scheme.
* libltdl/ltdl.h (lt_dlhandle): Be truly opaque with a void *.
* libltdl/lt_dlloader.c (lt_dlloader_remove): Party to
lt__private.h, so use internal lt__handle instead of opaque
lt_dlhandle.
* libltdl/ltdl.c (LT_DLGET_FLAG, LT_DLSET_FLAG): Add a cast to
internal lt__handle type.
(try_dlopen, tryall_dlopen, load_deplibs, unload_deplibs): Ditto.
(lt_dlexit, lt_dlclose, lt_dlsym): Use lt__handle to iterate
throught the handle list.
(try_dlopen): Use lt__zalloc instead of MALLOC and memset.
* libltdl/ltdl.h (lt_dlcaller_id): Be truly opaque with a void *.
(lt_dlhandle_interface): New callback type for filtering handles
according to the interface they present.
* libltdl/ltdl.c (lt_dlcaller_register): Take an id and an
interface check callback, and generate a caller_id.
(iterator): New static variable for the use of...
(lt_dlhandle_first): New function. Set the iterator for
subsequent calls to lt_dlhandle_next.
(lt_dlhandle_next): Either work as before when iterator is unset,
or else skip handles that fail the interface check in iterator set
by lt_dlhandle_first.
* libltdl/ltdl.h (lt_dlhandle_first): Declaration.
* doc/libtool.texi (User defined module data): Document the new
APIs.
* NEWS: Updated.
`loaders' list management into a new SList ADT. In the process,
the API for writing loaders is a little cleaner, so all the
existing loaders were tweaked to take advantage of that:
* libltdl/slist.h, libltdl/slist.c: New files implementing a
generic singly linked list container ADT. The ADT is purely
internal, and none of its API's are visible from an installed
libltdl.
* libltdl/lt_dlloader.h (lt_dlloader): Removed next field again
:-) Renamed to lt_dlvtable for API. Changed all callers.
(lt_dlloader_get): New function to turn an lt_dlloader into its
associated lt_dlvtable.
(lt_dlloader_add): Removed unused data parameter. The caller
data belongs to (and is set by) the loader itself, not the
loader's client. Changed all callers.
(lt_dlloader_name, lt_dlloader_data): Removed. Use
lt_dlloader_get instead!
* libltdl/lt__private.h: Include slist.h.
(lt__alloc_die_callback): Add missing LT_SCOPE to declaration.
(lt_dlhandle_struct): Use lt_dlvtable instead of opaque
lt_dlloader.
* libltdl/ltdl.c (lt_dlexit): Rewritten for the new loader API.
(loaders, lt_dlloader_add, lt_dlloader_remove, lt_dlloader_next,
lt_dlloader_find): Moved from here...
* libltdl/lt_dlloader.c ((loaders, lt_dlloader_add,
lt_dlloader_remove, lt_dlloader_next, lt_dlloader_find): ...to
here. And rewritten in terms of new SList interface.
* libltdl/ltdl.c (lt_dlexit, tryall_dlopen): Rewritten in terms of
new lt_dlloader interface.
* libltdl/Makefile.am (libdlloader_la_SOURCES): Add slist.h and
slist.c. Move lt_dlloader.h from here...
(pkginclude_HEADERS): ...to here.
(libltdl_la_SOURCES): Add lt_dlloader.c and lt_dlloader.h.
