New in CVS version 1.2g, Libtool team: * AM_PROG_LIBTOOL is smaller and faster * AC_LIBTOOL_WIN32_DLL is required in configure.in for libtool to attempt to build dlls on win32 hosts * Shared libraries on AmigaOS up to version 4 are now disabled since they don't meet libtool's requirements for shared libraries * -L supports now relative directories * Libltdl has a new license: LGPL with a special exception * Libltdl can be used as stand-alone package * dlopen support for BeOS * Partial support for Motorola System V 4 * Improved support for AIX, BeOS, Cygwin, DJGPP, DU, IRIX and HP/UX * Documentation updates * New tests * Bugfixes New in 1.2f: 1999-03-15; CVS version 1.2e, Libtool team: * 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 New in 1.2d: 1998-12-16; CVS version 1.2c, Libtool team: * libtool will correctly link already-installed libraries into programs. * New -module flag, to create loadable modules. * New libltdl, a small library for portable dlopening of modules. It is still undocumented, but you can already find some examples in: * New mdemo directory, with tests of -module and dlopening examples. Be aware that libltdl is only known to work on a few platforms such as GNU/Linux and Solaris2. Some mdemo tests are known to FAIL on several other platforms; please ignore these failures by now (or work to fix them :-). * Inter-library dependencies patch finally integrated, but there's still much porting to do. See PORTING for details (some plans for the future in mail/deplibs in the CVS tree). * New option -export-symbols to control symbol exporting when possible. * Fixed -export-dynamic problem with C++ programs in egcs 1.1. * New dlpreopen structure. * libtool now supports `-c -o' and subdirectories in sources and target object names even in platforms whose compilers do not support this. In this case, file locking occurs to avoid problems with parallel builds. * New `echo' variant that should fix most problems with long command lines and broken printf programs. * Support for DG/UX, UnixWare 7.x and FreeBSD 3.0, and improved support for Microsoft Windows * Various bugfixes * We now have anonymous CVS access to GNU libtool. CVSROOT is :pserver:anoncvs@anoncvs.gnu.org:/gd/gnu/anoncvsroot. The password is empty. The directory is libtool. Check our home-page at http://www.gnu.org/software/libtool/libtool.html for details. * Alexandre Oliva, Thomas Tanner and Gary V. Vaughan have taken over the maintenance of libtool. * Arguments to ltconfig have been changed to allow creation of a libtool C program, totally unusable as of this release. New in 1.2b - 1998-07-01, Gordon Matzigkeit: * Libtool needs a new maintainer, since Gordon Matzigkeit has quit. If you think you can do the job, send mail to bug-libtool@gnu.org. * Bug fixes. * Support for libtool convenience archives. New in 1.2a - 1998-04-19, Gordon Matzigkeit: * Bug fixes. * ltconfig accepts an `--output' option to specify the name of the generated libtool. * New `--debug' flag to turn on shell script tracing for libtool, libtoolize, and ltconfig. * Added `libtool --config' to print out all configuration variables. * Support for *-*-hpux11*. New in 1.2 - 1998-03-20, Gordon Matzigkeit: * Minor bug fixes to provide a stable public release. * Libtool no longer causes Solaris printf to barf due to silly 2110-byte static buffers. New in 1.1 - 1998-03-08, Gordon Matzigkeit: * Bug fixes. * http://www.profitpress.com/libtool/ is libtool's homepage. * `AM_PROG_LIBTOOL' supports turning shared or static libraries off with the `--enable-shared=PKGS' and `--enable-static=PKGS' configure flags. See (libtool)AM_PROG_LIBTOOL. * Use the `AM_DISABLE_SHARED' or `AM_DISABLE_STATIC' macros if you wish to modify the default behaviour of `AM_PROG_LIBTOOL' for your package. * New rules for `AM_PROG_LD' to use gcc's `-print-prog-name' flag in order to find ld, if possible. * Suppress duplicate compiler output during `compile' mode. * Deleted `dlname' mode. Dlopen applications should only use the runtime search method described in (libtool)Finding the dlname. * Experimental support for dynamically loaded modules, even on static-only platforms, via new `-dlopen' and `-dlpreopen' link flags. * `compile' mode honours the `-static' flag to prevent libtool from building PIC objects. * New `execute' mode to support debugging uninstalled libtool libraries and executables. * `-allow-undefined' is now the default. You can use `-no-undefined' to declare that a shared library is completely self-contained. * Inter-library dependencies are automatically handled when linking against an uninstalled `.la' file. * New `-all-static' flag to prevent any dynamic linking. The regular `-static' flag now just prevents dynamic linking of libtool libraries. * New `-release' flag to encode release numbers into libtool libraries. This breaks binary compatibility, but is useful for libraries whose interfaces change very frequently. See (libtool)Versioning. * The `-rpath' flag can be used to hardcode absolute directories when linking executables using libtool. * New robust quoting code to handle any metacharacters passed in arguments to libtool commands. * Full support for broken collect2 on AIX 3. Shared libraries can now be built with all working versions of GCC on AIX. * Shell script speed optimizations for old and buggy /bin/sh systems, such as HP-UX 9 and SunOS 4.1.4. * Maybe use `_libs' as a temporary libtool directory instead of `.libs' in order to cope with MS-DOS filenames. * Portability fixes for Windows NT. * Refuse to create libtool libraries that don't begin with `lib'. This allows us to correctly handle OSes that don't have the `lib' prefix by default, such as OS/2. * Support for *-*-amigaos*, *-*-os2*, *-*-sysv4.2uw2*, and *-*-uts4*. New in 1.0 - 1997-07-08, Gordon Matzigkeit: * Bug fixes. * Better configuration test to find the system linker. The old test was failing because people frequently install GNU ld, but don't necessarily configure GCC to use it. * Automake support for Libtool now uses the LTLIBRARIES primary. See the Automake documentation for more information. * Added new `--disable-static' flag to disable building static libraries on platforms that have shared libs. * New `-allow-undefined' link flag to build shared libs that contain references to unresolved symbols. * Removed all support for creating static-only libraries. * Basic support for dynamically loaded modules: new `-export-dynamic' linking flag and corresponding `dlname' mode. * New `--features' flag to display configured libtool attributes. * Added support for installing libtool objects, both in absolute and relative directories. * Support *-*-linux-gnu* as an alias for *-*-linux*. * Support for *-*-openbsd* and *-*-freebsd3*. New in 0.9 - 1997-02-03, Gordon Matzigkeit: * Bug fixes. * The libtool demo now uses the libm cos(3) function, to demonstrate inter-library dependencies. * The PLATFORMS file has been moved to doc/platforms.texi. New in 0.8 - 1997-01-26, Gordon Matzigkeit: * Bug fixes, and more documentation. * Basic support for other language compilers (C++, Fortran, and preprocessed assembler). * Libtool is now more persistent when linking with the `-static' flag fails. * New test for hardcoding system linkers, to verify that libtool neither creates incorrect binaries, nor takes unnecessary precautions while linking against uninstalled shared libraries. * For clarity, the demo subdirectory no longer uses ansi2knr, and has been rewritten to avoid ANSI-only constructs. * Support for *-*-irix5, *-*-irix6*, and *-*-sco3.2v5*. New in 0.7 - 1996-12-08, Gordon Matzigkeit: * Total rewrite of libtool, along with a new model for library building. * Completely rewritten documentation for the new paradigm. * Sane handling of broken system linkers, such as the ones on AIX and HP-UX. * configure mode is now a separate program, `ltconfig' * The libinfo helper script has been incorporated into the main libtool program. * Automatic mode guessing, based on the command line. * Full support for Automake 1.2 (including ansi2knr features). * Support to create reloadable objects using link mode. * Support for new `-static' linking flag. * Support for stripping libraries during installation. * Library version information is now passed on the command line, not through a version file. Version 0.6 was never released. New in 0.5: * Disabled install-progs until next version, when it will be correctly implemented. * Clearer library versioning documentation. See (libtool)Versioning. * Renamed gm_PROG_LIBTOOL to AM_PROG_LIBTOOL * Libtool now creates pseudo-objects named foo.lo and pseudo-archives named libfoo.la instead of foo.o and libfoo.a. See the documentation. * libtool compile doesn't interfere with user CFLAGS if they don't conflict with the current objtype. From Karl Berry. * Created new libinfo helper script. * libversion.in files are obsolete -- libtool uses libinfo to read the new LIBINFO files. * Libtool is better at finding its config file and helper scripts. * Support for *-*-gnu* New in 0.4: * Bug fixes and new regression tests * On unsupported configurations, ``libtool configure'' demotes OBJTYPES to `standard' instead of aborting * Added new object type, `t', for tcov(1) support * Support for *-*-aix3*, *-*-aix4*, *-*-hpux10*, *-*-osf3*, and *-*-solaris2* New in 0.3: * Bug fixes and new regression tests * Added new uninstall-libs mode * Added a host argument to configure mode * Fixed debugging/hyper-optimizing flags conflict (from Karl Berry) * Support for --no-whole-archive when needed by GNU ld (from Ulrich Drepper) * Implementation of --enable-linktype, --enable-profile, --enable-shared, --enable-static in gm_PROG_LIBTOOL macro * New `libtoolize' program (modeled after GNU gettext's `gettextize') to help conversion to libtool * New ABOUT-LIBS document for inclusion with libtool-supported packages New in 0.2: * Support for *-*-linux * Better checking for GNU ld * Reimplemented the config file so that it corresponds more closely to the variables listed in (libtool)Porting Libtool. * Reimplemented the shared library version scheme. See (libtool)Versioning. * Replaced `--config-file' and `--version-file' options with `--confdir' * Added new install-libs and install-progs modes New in 0.1: * First release of libtool * Support for: *-*-freebsd*, *-*-netbsd*, *-*-sunos4*, *-*-ultrix4*
