itself, does not link against an uninstalled library. It appears
that this can happen if you are building a project where:
(1) there is a library
(2) there is an executable that does not, itself, link against
that library
In this case, notinst_deplibs is empty, and when the wrapper
script is loaded by libtool during ./libtool mode=install, there
is a check for "is notinst_deplibs empty". In this case, it is,
so libtool reports an error.
I don't think it is wrong to have a wrapper script for an exe that
*technically* doesn't need it. But instead of checking for
notinst_deplib nonempty as a proxy for "did wrapper script get
sourced into my environment properly" a different var should be
used.
* config/ltmain.m4sh (func_mode_install): set new variable
`generated_by_libtool_version' in wrapper script when using
libtool_install_magic. When verifying that wrapper script was
properly sourced, check that `generated_by_libtool_version' is
non-empty, instead of using notinst_deplibs.

experiments in Autoconf 2.52 era. Updated the rest and moved into
Makefile.am.

Without this change, the distributed libtool tarball has a
dependency on autom4te. There was some inconsistency in the
filenames: now we have foo.m4sh -> m4sh -> foo.in -> configure

(func_scan_files): Also set seen_ltdl for LTDL_INIT and
LT_WITH_LTDL.
* libltdl/ltdl.c (lt_dlforeachfile): LT_SYS_LIBSEARCH_PATH is not

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.

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.
* libltdl/lt_dlloader.h (lt_dlloader): Add next field.
* libltdl/ltdl.c (lt_user_dlloader): Remove entirely. Change all
callers to use lt_dlloader instead. Add a compatibility macro.
(lt_dlloader_add): Remove copy and allocate stage, just hook
directly into the loaders list.
than my move of the module field into lt_dlinfo:
* libltdl/ltdl.c (lt_caller_data, lt_dlhandle_struct): Move from
here...
* libltdl/lt__private.h (lt_caller_data, lt_dlhandle_struct):
...to here. And put the module field back here...
* libltdl/ltdl.h (lt_dlinfo): ...instead of here.
* libltdl/loaders/loadlibrary.c (vm_open): Adjust.
operation of libtool (neither would work alone). First, there is
a new feature that allows libraries to preopen modules. This
entails a backwards incompatible change to the libltdl API for
separating out the preloaded symbol lists by owner. Second, in
the tradition of "eating our own dogfood", libltdl now preloads
its own dlloaders. The internal API for dlloaders has also had to
change in a backwards incompatible way in support of the new
library preloading feature. If you don't use preloaded libraries,
you needn't change your project sources, though you will need to
recompile against the new libltdl. The API changes are mostly
confined to dlloaders, so you probably needn't worry about those
(unless you have written a custom loader that you want libltdl to
use):
* configure.ac (AC_CONFIG_FILES): Add libltdl/loaders/Makefile.
* libltdl/configure.ac (AC_CONFIG_FILES): Add loaders/Makefile.
* libltdl/loaders: New directory for module loaders, to simplify
Makefile rules, and to give the loaders themselves names that are
unique in the first few characters.
* libtoolize.in (func_copy_all_files): Copy recursively to pick up
the loaders directory contents.
* libltdl/loaders/Makefile.am: New file. Move module building
rules to here...
* libltdl/Makefile.am: ...from here.
(VERSION_INFO): Bumped version info to signify interface changes.
(libltdl_la_CPPFLAGS, libltdlc_la_CPPFLAGS): Set LTDLOPEN
appropriately for each library.
* libltdl/loader-dld_link.c, libltdl/loader-dlopen.c,
libltdl/loader-dyld.c, libltdl/loader-load_add_on.c,
libltdl/loader-loadlibrary.c libltdl/loader-preopen.c,
libltdl/loader-shl_load.c: Moved from here...
* libltdl/loaders/dld_link.c, libltdl/loaders/dlopen.c,
libltdl/loaders/dyld.c, libltdl/loaders/load_add_on.c,
libltdl/loaders/loadlibrary.c libltdl/loaders/preopen.c,
libltdl/loaders/shl_load.c: ...to here.
(get_vtable): New entry function for each.
* libltdl/loaders/preopen.c (lt_dlsymlists_t): Replaced by...
(symlist_chain): ...a new structure which maps lists of preloaded
symbols from the object that loads them.
(lt_dlpreload_open): New function to automatically open all
preloaded modules belonging to a named object (ORIGINATOR).
* libltdl/lt__alloc.c (lt__zalloc): New function to return a block
of zeroed out new memory.
* libltdl/lt__alloc.h (lt__zalloc): Prototype it.
* libltdl/lt__private.h (lt__alloc_die_callback): Add missing
prototype.
(lt__error_strings): Make this opaque to callers.
* libltdl/lt_error.c (lt__error_strings): Move the implementation
to here.
* libltdl/lt_dlloader.h (lt_user_dlloader): Add extra fields to
make originator focused preloading possible. *BREAKS BACKWARDS
COMPATIBILITY*
(lt_dlloader_add): Take advantage of new fields to simplify
paramater list.
* libltdl/lt_system.h (LT_STR): New ANSI stringification macro.
(LT_CONC): Fix it to work from within macros.
* libltdl/ltdl.c (loader_init, loader_init_callback): Simplify
dlloader loading.
(get_vtable, preloaded_symbols): Point these at the preopen.c
symbols to bootstrap the loader chain.
(lt_dlinit): Load the preopen dlloader manually, and then use it
to load any other preloaded dlloaders.
(lt_dlloader_add): Simplify parameter list. Populate new
fields. Chain new loaders according to priority field.
* libltdl/ltdl.h (lt_dlsymlist): Add a new originator field.
(lt_dlpreload_callback_func): Type of a callback for automatic
lt_dlpreload_open loading.
(LTDL_SET_PRELOADED_SYMBOLS): Adjust to hook into preloaded
symbols from the "@PROGRAM@" originator.
* tests/demo/dlmain.c (main): Use mangled preloaded_symbols symbol.
* tests/pdemo/longer_file_name_dlmain.c (main): Ditto.
* ltmain.in: Don't spew spurious warnings when dlopening and
dlpreopening modules.
(func_generate_dlsyms): Factored out from multiple copies in the
rest of the code. Generate originator keyed symbol lists.
(func_extract_archives): Also factored. Extract the contents of
convenience archives for linking with dependent libraries when
--whole-archive is not available.
[darwin]: Don't try to link $old_library unless it exists, and
$lib is a bundle.
* m4/ltdl.m4 (AC_LTDL_DLLIB): Check for all possible dynamic
loading libraries/apis rather that stopping when an acceptable one
is discovered.
(LT_DLLOADERS): New variable for holding dlloaders that can be
preloaded.
* doc/libtool.texi: Document interface changes.
* NEWS: Updated.
* libltdl/ltdl.c (lt_dlhandle_struct): ...from here. Changed all
callers.
* libltdl/loader-loadlibrary.c (sys_wll_open): Use new inteface to
scan loaded handle->info.module fields for previously loaded
modules.
* doc/libtool.texi (User defined module data): Document changes to
the interface.
* NEWS: Updated.
