| * 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 |

| * 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 |

| 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 |

| 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 cseses 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: |

| * 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* |
