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

New in 1.9f: 2004-??-??; CVS version 1.9e, Libtool team:
* Fix a regression in 1.9d, where ECHO was always set to 'echo' and the
  backslash quoting tests were never run.
* Fix a regression in 1.9d, where progpath was used for --no-reexec before it
  was set.
* Fix a regression in 1.9d, which required an installed automake to build the
  bootstrapped tarball.
* Fix hanging bug on MinGW.

New in 1.9d: 2004-10-03; CVS version 1.9c, Libtool team:
* 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.
* When compiling C glue code with $LTCC, libtool now saves the setting of
  $compiler_flags from the C tag, and passes those flags to $LTCC.
* libtool no longer dies when concurrently creating directories with
  `make -j' on multi-processor hosts.
* Return type, and name parameter of lt_dlloader_remove are no longer
  `const'.
* Name parameter of lt_dlloader_find is no longer 'const'.
* The API for the slist ADT has been updated: slist_new has been replaced
  by slist_box; slist_unbox and slist_sort are new; the footprint of
  slist_remove and slist_fnid have changed; SListCallback and SListCompare
  types have been exchanged.  See libltdl/slist.c for documentation.
* libltdl is C89 compatible again.  lt_dlsymbol type removed, and lt_dlsymlist
  structure changed to avoid using C99 flexible arrays.
* Support self dlopening for executables on cygwin and mingw.
* Improved support for linux-gnu/ia64.
* Initial support for s390x-ibm-tpf.
* Fixed some memory leaks in libltdl.

New in 1.9b: 2004-08-29; CVS version 1.5a, Libtool team:
* The /^_?LT_[A-Z_]+$/ namespace is now reserved for Libtool's own macros.
  If you have any shell variables in this namespace they will need to be
  renamed.  If you have any macros in this namespace please rename them to
  prevent any possible future clash with libtool supplied macros.
* New LT_PREREQ macro for specifying minimum libtool requirement.
* New LT_INIT interface replaces AC_PROG_LIBTOOL, AC_ENABLE_SHARED,
  AC_DISABLE_SHARED, AC_ENABLE_STATIC, AC_DISABLE_STATIC,
  AC_ENABLE_FAST_INSTALL, AC_DISABLE_FAST_INSTALL, AC_LIBTOOL_DLOPEN,
  AC_LIBTOOL_WIN32_DLL and AC_LIBTOOL_PIC_MODE.  Use autoupdate to modernise
  your configure.ac files after installing this release.
* New LT_LANG interface to enable libtool support for a specific language.
* Language support is now only included if your configure.ac enables it,
  either through a call to AC_PROG_CXX etc. or LT_LANG.
* The libtool script will complain if it was built from mismatched ltmain.sh
  and libtool m4 macro versions.
* Like automake, libtoolize no longer installs config.guess and config.sub by
  default.  Use new --install option to get the old behaviour.
* libtoolize no longer supports the --ltdl-tar option.
* libtool script is now created by config.status.  Instead of interrogating
  `./libtool' from configure.ac after calling AC_PROG_LIBTOOL, use the
  variable names directly.
* libltdl is no longer a self-contained package, and shares configury with
  the top level directory now.
* Shared objects (.lo) are no longer created when `-static' is passed in
  compile mode.
* New compile mode option `-shared' prevents creation of static objects (.o).
* New link mode option `-shared' creates only shared libraries at link time.
* If you configure libtool with --disable-shared (or if libtool does not
  support shared libraries on your platform) trying to build a library using
  `-shared' is a fatal error.
* New link mode option `-weak' tells libtool when not to propogate dependency
  libraries from dlpreopened modules.
* libtoolize installs libtool.m4, (ltdl.m4 if used,) and various supporting
  m4 definitions to AC_CONFIG_MACRO_DIR.
* Mode inferrence removed, shorthand for choosing modes added.
* Specifying -allow-undefined is now an error.
* Speed up max_cmd_len check.
* libltdl can now preopen modules from within a library, and libtool will
  accept -dlpreopen options when linking either a shared library or a
  convenience library.
* New function in libltdl: lt_dlhandle_find provides access to module handles
  by module name.
* New function in libltdl: lt_dlpreload_open opens all preloaded modules.
* libltdl no longer loads shared libraries with global symbol resolution,
  this caused problems when the symbols were intended to be overriden further
  up the stack; it is also not recommended practice.
* New function in libltdl: lt_dlhandle_first, primes handle iterations (using
  lt_dlhandle_next) to filter by module interface.
* libltdl no longer tries to support multi-threaded programming with
  lt_dlmutex_register(), which was unusable with POSIX threads anyway.
  The symbols are deprecated but exported for backwards compatibility.
* libltdl no longer uses lt_dlmalloc, lt_dlrealloc and lt_dlfree.  The symbols
  are still exported for backwards compatibility.
* The lt_dlinfo struct has a new module field that can be used by dlloaders.
* libltdl no longer supports pre-c89 compilers.  Some of the pre89 portability
  functions had compile time bugs in them anyway, so you guys can't have been
  using it :-)
* make install now deletes preexisting $prefix/share/libtool before installing
  latest files.
* Extracting symbols from an import library on cygwin and win32 now works.
* Initial support for amigaos-ppc.
* Improved support for OpenBSD.
* Support for Intel C++ version 8.0.
* New support for IBM's xlc and xlc++ on Mac OS X.
* Finished support for QNX RTOS.

  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.

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,

* 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 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
