NEWS - list of user-visible changes between releases of GNU Libtool
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*
