Ralf Wildenhues
The Libtool Team would like to announce alpha release 1.5.23b of GNU Libtool.
This prerelease should help shake out any remaining bugs for 1.5.24. Ideally, the releases will be identical, so please test it on your systems and with your software packages as much as you can. This release fixes a couple of regressions on BSD systems, hopefully improves multilib support, and treats Cygwin more like MinGW; see the NEWS excerpt below.
New in 1.5.23b: 2007-02-17

Initial support for RDOS.
Fix regression on DragonFly that disabled library hardcoding.
Fix regression on OpenBSD, NetBSD, DragonFly, and other systems with hardcode_direct=yes that wrongly removed paths to uninstalled libraries during link mode.
Let libltdl know that FreeBSD and DragonFly dlopen causes dependent modules to be loaded. This fixes excessive load times for modules with large library dependency graphs.
Fix error with -version-info on systems with version_type=none, such as BeOS.
Initial support for the Sun compiler suite on GNU/Linux.
Improved support for GNU/kFreeBSD and GNU/NetBSD.
Search paths with GCC on multilib systems like x86_64 have been fixed.
The libtool --tag argument which has been supported since version 1.5 is documented now.
Fix regression in libltdl symbol exports on Cygwin. Side effect: LT_GLOBAL_DATA and LT_SCOPE are now explicitly defined as declspec(dllexport), bypassing auto-export logic on Cygwin. This tracks existing behavior on MinGW.
Bug Fixes.

The Libtool Team is pleased to announce the release of GNU Libtool 1.5.22.
This release fixes quite a number of bugs, one of them a minor local security issue.
New in 1.5.22: 2005-12-18

Fix 1.5 regression that caused linking a program `-static' to also link statically against installed libtool libraries, contrary to documented (and actual 1.4.x) behavior.
Fix file ownership for BSD `ranlib'.
Initial support for Beos/C++.
Fixed detection of link_static_flag, and self-dlopening.
Fixed setting of shlibpath variables (LD_LIBRARY_PATH and similar) and order of link search paths for creating and testing of uninstalled libraries.
Fix silent failure of `libtoolize --ltdl' if libltdl files not present.
Fixed command line settings for non-GCC compilers, Solaris/64bit.
Support for Interix 3 (Windows SFU).
If non-pic objects were not compiled, and libtool is called in link mode, libtool no longer silently creates an empty archive, but rather falls back to pic objects.
Fix potential denial of service by malicious other users for tmpdir directory creation at relink time.
Bug Fixes, among others for AIX, Cygwin, Darwin, FreeBSD, HPUX, MinGW, OpenBSD, UnixWare.

lt_dlrealloc is an official part of the libltdl API.
--tag, --silent and --debug options are preserved and reused when libtool calls itself for relinking etc.
`-pthread' and similar options are honoured when linking shared libraries.
-no-suppress in compile mode shows compiler output for both PIC and non-PIC object compilation.
New link mode option `-precious-files-regex' to prevent accidental removal of files you want to keep, such as test coverage data, from the temporary output directory.
Directories specified in /etc/ld.so.conf are no longer hardcoded on Linux.
Recognises the 'R' symbol type on Solaris so read-only symbols can be exported.
Bug fixes.

I've just uploaded libtool 1.4.3 and 1.5 tarballs to ftp.gnu.org with the new automated upload system, along with xdelta and diff files, plus detached signatures for the whole lot.
The md5sums of all files are as given below, but you should download the associated .sig and run:
gpg --verify <filename>.sig
My public signature is available from my website, and wwwkeys.uk.pgp.net, and will gradually arrive on most keyservers shortly.
Sorry for the enormous delay, we will hopefully make it up to you with Libtool 1.6.

I am pleased to announce the release of GNU Libtool 1.5, the first release in the 1.5 series. Some features of the new release are:

Full multi-language support.
Support for Mac OS/X.

Piecewise linking of libraries too large to be linked in one step.

There are also a large number of incremental improvements and bugfixes since the last release.
This release was bootstrapped and tested with Automake 1.7.3 and Autoconf 2.57, but can be used in conjunction with any newer release of either of these in your own projects.
Tarballs and both traditional and xdelta diffs against release 1.4.3 are available now from ftp.gnu.org, and will soon arrive on all gnu mirrors:

This release was bootstrapped and tested with Automake 1.4-p5 and Autoconf 2.13, but can be used in conjunction with any newer release or either of these in your own projects.
Tarballs and both traditional and xdelta diffs against release 1.4 are available now from ftp.gnu.org, and will soon arrive on all gnu mirrors:

The Libtool Team is pleased to announce alpha release 1.4b of GNU libtool. This is the first release to include the code that has been in development on the multi-language-branch for the last 18 months or so, that was recently merged into the mainline development sources.
libtool-1.4b is available now from ftp://alpha.gnu.org/gnu/libtool/libtool-1.4b.tar.gz. You will find diffs and xdeltas from libtool-1.4 on alpha.gnu.org.
If you prefer, you can fetch the unbootstrapped sourcecode using anonymous CVS by following these instructions but using the tag release-1-4b.
The main difference between this release and libtool-1.4 is the folding in of code developed on the multi-language-branch.
Enjoy!

On the 2nd Anniversary of the release of libtool-1.3, the Libtool Team is delighted to announce libtool version 1.4: Available now from http://ftp.gnu.org/gnu/libtool/libtool-1.4.tar.gz and shortly from all GNU mirror sites. You will find diffs and xdeltas from libtool-1.3.5 on ftp.gnu.org, and diffs and xdeltas from libtool-1.3d on alpha.gnu.org.
If you prefer, you can fetch the unbootstrapped sourcecode using anonymous CVS by following these instructions but using the tag release-1-4.
The main difference between this release and libtool-1.3d is the addition of many small patches to improve the performance of the test suite on several host architectures.
Enjoy!

As reported in the mailing list, we have moved the development CVS repository to ffii.org. Eventually, we hope to mirror this back to gnu.org so that anoncvs access will continue to work as before. In the interim, the latest development code is available from ffii.org (press enter at the password prompt):
  $ cvs -d :pserver:anoncvs@anoncvs.ffii.org:/var/cvs login
  Password:
  $ cvs -d :pserver:anoncvs@anoncvs.ffii.org:/var/cvs co libtool
  
Also, daily snapshots of the trunk can be downloaded from ftp.ffii.org if you can't do CVS.

Today, in libtool's 3rd birthday (according to Gordon's ChangeLog :-), the libtool team is pleased to announce the alpha release 1.2f of GNU libtool. It is the basis for release 1.3, that will hopefully be out in a few weeks and will contain only bug-fixes.
GNU libtool 1.2f is available at ftp://alpha.gnu.org. Diffs from older releases are not available because they'd account for more than 60% of the size of the distribution, although xdeltas are available because they are much smaller. Alternatively, you can get the distribution from the CVS repository, using the release-1-2f tag (see this section for instructions on how to retrieve libtool via anonymous cvs).
The user-visible changes since release 1.2d follow: (from the NEWS file)

libtool will correctly link uninstalled libraries into programs and prefer uninstalled libraries to installed ones
library paths that are in the system default run-time search path are no longer hardcoded into executables.
New fast installation mode, which links the final executable in order to avoid relinking during installation.
Programs in the build-tree are relinked when executed.
New AC_DISABLE_FAST_INSTALL macro to set the default for the fast-install mode to disabled
New -export-symbols-regex flag, to export symbols selectively by a regular expression
Support -R for specifying run-time path of programs and library dependencies.
New -avoid-version option to avoid versioning for libraries
libtool module names no longer need to have a lib prefix (requires automake 1.4).
New -thread-safe flag, to build thread-safe libraries
Major improvements in libltdl: API documentation, installable version, support for module search paths, support for lt_dlopen(0), can be embedded into packages as a tar file (libltdl.tar.gz), dynamic buffer allocation and buffer overflow checks, new macro LTDL_SET_PRELOADED_SYMBOLS() which must be used in the main program, dynamic memory allocation functions are user-defineable.
New AC_LIBLTDL_CONVENIENCE and AC_LIBLTDL_INSTALLABLE macros, to select convenience and/or installable versions of libltdl.
libltdl is now built and installed unless --disable-ltdl-install
New -dlopen self flag for dlopening the executable itself
New AC_LIBTOOL_DLOPEN macro to check for dlopen support, required if you use -dlopen or -dlpreopen
If libtool could not satisfy all dependencies of a module it will only build a static version of it
dld_preloaded_symbols was renamed to lt_preloaded_symbols
Support for BeOS
Improved support for FreeBSD, AIX, IRIX, OSF, SysV 4.3, HP/UX, DJGPP, BSD/OS 4.x and NetBSD
In order for libtool to attempt to link a shared library (dll) on win32 platforms, you must pass the -no-undefined flag to libtool in link mode.
The path to GNU ld now works on cygwin-b18 to cygwin-b20.2 at least.
Support for IRIX library versioning.
New demos and tests
Various bugfixes

Enjoy!

Work on win32 support on the ild-branch continues apace, and will be merged into the trunk after 1.2f has been released. Libtool now accepts dll objects on the command line, and will generate an export list and import library on the fly to make this possible. This feature also solves the win32 problem with the import library associated with a dll using the same filename as the matching static archive.
There are a few small issues which need resolving before 1.2f is ready for release, not least of which is that lt_dlopen(NULL) is broken on OSF/1.
There is a new configure parameter, `--enable-fast-install' which controls whether a libtoolized package built on a machine which needs to relink installed libraries and binaries does the relink during the build. The default is to link build tree executables to load installed libraries so that no relink is necessary as these executables will run correctly when installed; if these executables are run in the build tree, they will be relinked on demand before being executed. If `--enable-fast-install=no' is used, then the executables in the build tree will be linked to load uninstalled libraries so that no on-demand relink is necessary if these executables are run from the build tree; of course some platforms (such as linux and irix) will require that the programs be relinked during install in order to pick up the installed libraries in preference to the uninstalled libraries in the build tree.

Selective exporting has been implemented, so that it is now possible to limit the symbols lt_dlsym() will have access to. There are two new switches, `--export-symbols' and `--export-symbols-regex' to control this behaviour.
Portable support for using lt_dlopen(NULL) to get a handle on the main executable so that you can get the address of symbols in the executable itself with lt_dlsym() is now working. Ideally a package developer who wants to use this feature should use the new macro AC_LIBTOOL_DLOPEN in the package's configure.in, and arrange to have -dlopen self passed on the libtool link line.
Work on the full inter-library dependency support is now complete on the ild-branch of the repository, and is ready for merging onto the trunk for testing. It looks very much as though libtool-1.3 will have full ILD now!
There is some contention as to how we should best build one of the two binaries required on architectures which need to link executables which use installed libraries differently than when they use equivalent uninstalled binaries (currently we know about Linux and Irix). Some of us want to link the installable objects during the actual install; some of us want to link the objects which use uninstalled libraries on demand as they are executed in the build tree...

A HUGE thread about the automatic use of -rpath for libtool libraries on linux dominated the list this week. Ultimately, we (the libtool maintainers) await a patch to prevent libtool from using -rpath for system directories in /etc/ld.so.cache (not a typo). The root of the problem is that most linux distributions have upgraded their system to glibc (libc.so.6) by replacing all of the libc5 dependant libraries with their glibc equivalents. This becomes a big problem when someone tries to run a binary which was compiled with -rpath on a libc5 era distribution on a new machine which has replaced to libc5 dependant libraries with new versions linked against glibc, but without amending the soname of the new versions to clue the runtime linker in on the new dependencies. RedHat got around the problem by patching ld.so to search LD_LIBRARY_PATH before -rpath.
We are looking to release libtool-1.2f as a 1.3 candidate after a few oustanding issues have been resolved:

The documentation is still not quite in line with the code, and needs a little tidying.
We need to find a way to allow some platforms to explicitly exclude some symbols from dlpreopening symbol lists, in order for SunOS4 and FreeBSD to be able to pass `make check'.

The full inter-library dependencies support we wanted to get into 1.3 just got a whole lot more complicated. We want for executables and libraries to be able to link against a mixture of installed and uninstalled (libtool and non-libtool) libraries in the build directory so that tests can be run with the correct linkage. And libtool needs to be able to relink those targets against the installed libraries at install time.
The milestones are now as follows:

Selective symbol exporting and documentation cleanups for libtool-1.2f alpha release.
Fix any problems with libtool-1.2f alpha for libtool-1.3 release.
Finish up ILD, and merge back into the main source for libtool-1.4 (probably an alpha or two in between too).
Release-1.5 as soon as win32 dll data symbol exporting works transparently along with whatever other features we have by this time.

Somewhere along the way, or maybe after these releases, we would like to move all of ltconfig.in into libtool.m4 so that it runs as part of the configure script; and port ltmain.sh to C. The former may happen relatively soon. the latter probably won't!

Overhauled the web-site somewhat, and added a news page so that we can put up interesting items for people who are interested in libtool, but aren't subscribed to the mailing lists. We will try to update this on a weekly basis (or so), provided there is something interesting to say!
A few tidbits to get us started:

The release of libtool-1.3 is imminent, just as soon as we have fixed all known bugs in the 1.2d alpha. Many fixes are already in the cvs repository (version 1.2e).
There is a cvs branch for development of full support for linking with inter-library dependencies, which might make it into the 1.3 release.
