| NEWS - list of user-visible changes between releases of GNU Libtool | |
| New in 2.2.12 2010-08-??: git version 2.2.11a, Libtool team: | |
| * New features: | |
| - On non-cygwin Windows systems, we now lookup potential library | |
| file names without regard to file name case. | |
| - The old testsuite now uses the `parallel-tests' Automake test driver | |
| now for more concurrency and better test logging. For this, tests are | |
| run in verbose mode by default now. | |
| * Important incompatible changes: | |
| - Autoconf 2.62 and Automake 1.11.1 or newer are now required for | |
| bootstrapping Libtool. For using Libtool in your own projects, | |
| Autoconf 2.59 and Automake 1.9.6 should still work. | |
| * Changes in supported systems or compilers: | |
| - Initial support for the Microsoft C/C++ Compiler, with help from | |
| the compile script in unreleased Automake 1.12. Override the manifest | |
| tool used to embed the manifest resource through the environment | |
| variable MANIFEST_TOOL. | |
| * Bug fixes: | |
| - The `check-interactive' and `check-noninteractive' convenience make | |
| targets now also work for the old testsuite. | |
| New in 2.2.10 2010-06-10: git version 2.2.9a, Libtool team: | |
| * New features: | |
| - On non-cygwin Windows systems, we no longer try to lookup the POSIX | |
| format path recorded in $libdir of a pseudo-library when looking up | |
| the location of the library with the native tools. | |
| New in 2.2.8 2010-06-05: git version 2.2.7c, Libtool team: | |
| * No new features: | |
| - Bumped version number and promoted 2.2.7b release candidate to a full | |
| stable release. | |
| New in 2.2.7b 2010-05-20: git version 2.2.7a, Libtool team: | |
| * New features: | |
| - Libtool ships and installs man pages for libtool and libtoolize now. | |
| - New libtool command line flag --help-all. | |
| - New libtool command line flag --no-silent (with alternate spelling | |
| --no-quiet). This flag (re)enables the default informational messages, | |
| but has no effect on so-called "verbose" output messages. | |
| - New libtool command line flag --no-verbose, which disables only | |
| the extra "verbose" output messages and has no effect on the | |
| default informational messages. | |
| - New convenience make targets `check-noninteractive' to avoid long testsuite | |
| runs on Windows with popup windows in the middle, and `check-interactive' | |
| for the complement set of tests. | |
| - New link mode flag -bindir to specify the location for installed PE DLLs. | |
| - Wrapper scripts and wrapper executables for programs linked against | |
| uninstalled shared libraries now support command-line options --lt-debug | |
| and --lt-dump-script. | |
| * Important incompatible changes: | |
| - The wrapper command line option support described above introduces the | |
| following incompatibility: the wrapper will remove any command line | |
| options that begin with '--lt-*' from the argument list before launching | |
| (uninstalled) programs. Any '--lt-*' option on the command line not | |
| recognized by the wrapper will result in an error. | |
| * Changes in supported systems or compilers: | |
| - Improved support for 64bit Windows (mingw64). | |
| - Improved support for cegcc (Windows CE/PocketPC). | |
| - Support for GNU/kOpenSolaris (kopensolaris*-gnu). | |
| - Initial support for compilers on BlueGene BG/P. | |
| - Improved support for Atari FreeMiNT. | |
| - With binutils 2.19.50+, shared libraries can be built on AIX. | |
| - Initial support for the Cuda Compiler Driver on GNU/Linux. | |
| - Support for Haiku (i586-pc-haiku). | |
| * Bug fixes: | |
| - Fix 2.2.6 regression that prevented using the libltdl macros together | |
| with Autoconf 2.59 (`possibly undefined macro: LT_LIBEXT'). | |
| - Fix 2.2.4 regression that caused arguments with special characters | |
| to be mangled by the compile wrapper for uninstalled programs on MinGW. | |
| - libtool command line flag --verbose now also enables explicit | |
| verbose output, in addition to its previous behavior of (re)enabling | |
| only the default informational output. See New Features, --no-silent. | |
| - Link tests are guarded by cache variables so they can be avoided for | |
| bootstrapping purposes (e.g., when link tests are not possible). | |
| - Argument mangling of execute mode has been improved (i.e., lessened). | |
| - Fix 2.1b regression that caused nm to not be the default name lister. | |
| The regression affected mainly (arguably broken) cross compiles. | |
| - Fix long standing bug that caused compiler checks for Fortran and | |
| C++ compilers to run twice. | |
| - Link mode works around a parallel build failure on Darwin 9.6.0 due | |
| to the `ar' `flock'ing an archive upon extraction, by protecting the | |
| extraction of convenience archives with a lock. | |
| - The Libtool macro files do not contain instances of __oline__ any more, | |
| easing merges for configure scripts that are added to version control. | |
| - Fix ancient bug where "-Wc," was turned into "$wl" (typically "-Wl,") | |
| when using the compiler driver to link programs. Now "-Wc," is stripped | |
| just as it is when linking libraries through the compiler driver. | |
| - Symbol versioning works with the GNU gold linker now. | |
| - Fixes for detection of shared library dependencies on MinGW systems. | |
| - Fixed Sun compiler detection on Solaris with sunCC, sunf77 etc. names. | |
| * Miscellaneous changes: | |
| - The manual is distributed under the terms of the GNU FDL 1.3 now. | |
| New in 2.2.6 2008-09-05: git version 2.2.5a, Libtool team: | |
| * New features: | |
| - New lt_dloadvise_preload() call to set a hint that only preloadeded | |
| modules can be opened. | |
| - libtoolize no longer removes config.guess and config.sub, even when | |
| --install is passed. | |
| * Changes in supported systems or compilers: | |
| - Fixes for ifort on Darwin, and newer Intel compilers (icc 10, ifort 9) | |
| on GNU/Linux. | |
| - Fixes for cwrapper (cygwin/mingw) under -stdc=c99. | |
| - Support cross compile of MinGW with Wine. | |
| - Initial support for cegcc (Windows CE/PocketPC) cross compilation. | |
| - Initial support for lf95 (Lahey Fortran 8.1) on GNU/Linux. | |
| * Bug fixes: | |
| - Several testsuite issues have been fixed, thanks to user feedback. | |
| - Fix 2.2 regression that caused argz symbols to be exported from | |
| libltdl unrenamed on systems that do not have working argz. | |
| - Revert "lt_dlopen(NULL) works on AIX again.". It was not the | |
| correct fix. | |
| - Diagnose '-L' arguments correctly. | |
| - Libtool no longer tries to open devices as files in execute mode. | |
| - Libtool no longer removes *.gcno profile information from GCC. | |
| New in 2.2.4: 2008-05-04: git version 2.2.3a, Libtool team: | |
| * New features: | |
| - New libtoolize option --no-warn, for users that want to continue to | |
| use old libtool style without being nagged. | |
| - Options --debug, --no-warn, --quiet and --verbose can be passed to | |
| libtoolize through the environment variable LIBTOOLIZE_OPTIONS, for | |
| cleaner interaction between the user and libtoolize when called by | |
| autoreconf. | |
| * Bug fixes: | |
| - The documentation for lt_dlopenadvise showed the wrong type for | |
| the lt_dladvise parameter. | |
| - The public declarations for lt_dlhandle and lt_dladvise are now | |
| incomplete struct types rather than void*, which means that nearly | |
| all casting is eliminated allowing the compiler to provide more | |
| type checking. | |
| - libtoolize no longer reports up-to-date files that it would have | |
| copied, unless --force is passed. | |
| - No longer reports that lt~obsolete.m4 needs to be added to aclocal.m4 | |
| when it is already there. | |
| - When `aclocal' copied the libtool macros directly into `aclocal.m4' | |
| (i.e. AC_CONFIG_MACRO_DIR is not being used), libtoolize no longer | |
| reports that all macros need to be added to `aclocal.m4', and | |
| diagnoses only the macro files that are missing or not up-to-date. | |
| - libtoolize now advises use of AC_CONFIG_MACRO_DIR to keep matching | |
| libtool macros in-tree where appropriate. | |
| - libtoolize now advises use of `ACLOCAL_AMFLAGS = -I m4' (or | |
| equivalent) where appropriate, and errors out when ACLOCAL_AMFLAGS | |
| names a different directory to AC_CONFIG_MACRO_DIR. | |
| New in 2.2.2: 2008-04-01: CVS version 2.2.1a, Libtool team: | |
| * New features: | |
| - In compile mode, compiler output occurs in the user locale. This | |
| feature has been present in 1.5.26 but not in 2.2. | |
| * Changes in supported systems or compilers: | |
| - Initial shared library support for AmigaOS4 on powerpc. | |
| * Bug fixes: | |
| - Fix 2.2 regression in libltdl that causes memory corruption upon | |
| repeated `lt_dlinit(); lt_dlexit()'. | |
| - Fix 2.2 regression in libltdl that skipped the dlopen loader if | |
| the system also supports other loaders (e.g., Cygwin, HP-UX). | |
| - Fix 2.2 regression in that `libtool --mode=execute CMD ARGS' does not | |
| transform ARGS that do not look like shell or C wrappers of libtool | |
| programs. | |
| - Fix 2.2 regression that kept cross-compiling to w32 from working. | |
| - Several testsuite issues have been fixed, thanks to user feedback. | |
| New in 2.2: 2008-03-01; CVS version 2.1c, Libtool team: | |
| * Bug fixes: | |
| - argz.c, lt__dirent.c and lt__strl.c are correctly distributed with | |
| parent projects using nonrecursive libltdl. | |
| - libtoolize no longer tries to install libtool files when libltdl is | |
| used in a non-autoconf parent package. | |
| - Don't add the CXX tag to libtool when there is no C++ compiler, even | |
| if AC_PROG_CXX sets a default g++ compiler where no such compiler | |
| actually exists. | |
| - make distcheck DISTCHECK_CONFIGURE_FLAGS=--disable-ltdl-install | |
| works again. | |
| New in 2.1b: 2008-02-01; CVS version 2.1a, Libtool team: | |
| * Important incompatible changes and obsoleted features: | |
| - Removed deprecated APIs from libltdl: lt_dlcaller_register, | |
| lt_dlhandle_next, lt_dlhandle_find, lt_dlforeach, lt_dlmutex_register, | |
| lt_dlmutex_lock, lt_dlmutex_unlock, lt_dlmutex_seterror, | |
| lt_dlmutex_geterror, lt_dlmalloc, lt_dlrealloc, lt_dlfree. | |
| - The Libtool and libltdl macros and the testsuite now assume a C89 | |
| environment, consequently do not test for headers such as string.h, | |
| strings.h, memory.h any more. | |
| - 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. | |
| - The libtool script has been optimized a bit for more modern shells. | |
| This breaks use of the stdin file descriptor in libtool, and can | |
| break if a different shell is used to execute the libtool script | |
| than the one it was configured for. | |
| - The macros AC_ENABLE_SHARED, AC_DISABLE_SHARED, AC_ENABLE_STATIC, and | |
| AC_DISABLE_STATIC have been un-deprecated after deprecation in | |
| 1.9b. | |
| - The macro LT_WITH_LTDL has been renamed to LTDL_INIT. | |
| - Fixed a branch-1-5/HEAD regression to only link uninstalled libraries | |
| statically with `-static'. In order to compensate for this, there | |
| is a new link flag `-static-libtool-libs' to provide the previous | |
| `-static' semantics. | |
| * New features: | |
| - Fix installation of libltdl so that it does not need Autoconf and | |
| Automake installed, in order to be usable in another package. This | |
| lifts the restrictions introduced in 1.9b. | |
| - Default convenience or installable libltdl builds can optionally | |
| be declared using new `convenience' or `installable' options to the | |
| LTDL_INIT macro (as an alternative to individual LTDL_CONVENIENCE | |
| or LTDL_INSTALLABLE invocations). | |
| - New configure-time options to allow libltdl parent project builder | |
| to choose between installed and shipped libltdl, when invoking | |
| LTDL_INIT: --with-included-ltdl, --with-ltdl-include, | |
| --with-ltdl-lib. | |
| - New LT_CONFIG_LTDL_DIR macro to specify a different directory name | |
| for a convenience libltdl. | |
| - libtoolize has been completely overhauled. | |
| - `libtoolize --install' now also installs `install-sh'. | |
| - New libtoolize options: --non-recursive, --recursive, --subproject. | |
| These options control the way libltdl is installed into a package by | |
| libtoolize. The new recursive and non-recursive build modes for | |
| libltdl don't require a subconfigure any more. | |
| The Libtool package itself builds libltdl nonrecursively. | |
| - The 'nonrecursive', 'recursive' and 'subproject' libltdl build | |
| modes are given as LTDL_INIT options. | |
| - New make variable LTDLDEPS for use in output_DEPENDENCIES. | |
| - New multi-module-loader safe libltdl handle iteration APIs: | |
| lt_dlhandle_iterate, lt_dlhandle_fetch, lt_dlhandle_map. | |
| - New lt_dlinterface_register to maintain separation of concerns | |
| between modules loaded by different libraries. | |
| - New lt_dlopenadvise takes a new lt_dladvise type argument, which | |
| lets the caller request local or global symbol visibility from the | |
| module loader with lt_dladvise_local and lt_dladvise_global | |
| respectively. If neither is given, or if lt_dlopen (or lt_dlopenext) | |
| are called, then the system default module symbol visibility is used. | |
| - The new lt_dladvise_init/lt_dladvise_destroy based APIs also allow | |
| caller requests for a filename extension search with lt_dladvise_ext, | |
| and for marking a module unloadable with lt_dladvise_resident. | |
| - Allow shell special characters like `$' in source file names, but | |
| not in object names, to enhance GCJ support. | |
| - An entire new Autotest-based testsuite in addition to the old one. | |
| Both testsuites have been made more useful for testing | |
| cross-compilers. The new testsuite exposes many more issues, but | |
| may also be a little rocky on exotic systems. | |
| - In 1.9b, a new variable inherited_linker_flags has been added to the | |
| libtool library files. This variable takes flags that should be | |
| used by dependent libraries and programs, but that do not fit into | |
| `dependency_libs' for both clarity and backward-compatibility. | |
| * Changes in supported systems or compilers: | |
| - Removed bitrotted support for xlc on Mac OS X. | |
| - Detection of compiler wrappers distcc/ccache and $host_alias prefix. | |
| - Basic support for PIE (position-independent executables). | |
| - Support for DragonFly BSD, improved support for FreeBSD. | |
| - Improved support for GNU/kFreeBSD and GNU/NetBSD. | |
| - Support for Interix 3 (Windows SFU) and newer versions. | |
| - Support for AIX 6.1. | |
| - Improved support for UnixWare. | |
| - Initial support for RDOS. | |
| - Initial Support for FC (modern Fortran). | |
| - Support for Portland Group compiler, the Sun compiler suite on GNU/Linux, | |
| and initial support for the IBM compiler suite on GNU/Linux/ppc. | |
| - Support for linux-dietlibc (`diet' as well as `diet-dyn', separately). | |
| - Building libltdl with a C++ compiler has been undusted. | |
| - On (AIX?,) HP-UX, and OpenBSD, hardcoding has been changed to prefer | |
| rpath over absolute dependent library names. This fixes DESTDIR | |
| installs, among others, on the non-HP-UX/PA systems. | |
| - Use of C++ templates together with shared libraries has been | |
| improved on some systems and with some compilers, but is still | |
| ongoing work. Feedback is desirable here. | |
| * Bug fixes: | |
| - Fix libltdl on static platforms. | |
| - Search paths with GCC on multilib systems like x86_64 have been fixed. | |
| - Fixed a regression that prevented use of libltdl without autotools. | |
| - Fix error with -version-info on systems with version_type=none, such | |
| as BeOS. | |
| - Fix symbol exporting for cases where command line length limits are | |
| exceeded. | |
| - Improve linking with C++ libraries on Solaris with Sun compiler. | |
| - Fix installation of libraries that are required by installation | |
| commands such as `ln' or `rm'. | |
| - More robust parsing of mangled `.la' files inside libltdl, fixing a | |
| possible overrun and a crash due to memory exhaustion. | |
| - Fix compile command line for gcj on MinGW. | |
| - Some configure variables have been renamed to fix caching: | |
| lt_prog_compiler_pic_works to lt_cv_prog_compiler_pic_works | |
| lt_prog_compiler_static_works to lt_cv_prog_compiler_static_works. | |
| - Fix 1.9b regression: lt_dlopen(NULL) works on AIX again. | |
| - Loads of smaller bug fixes. | |
| New in 1.9f: 2004-10-23; 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 $LTCC. | |
| * libtool no longer dies when concurrently creating directories with | |
| `make -j' on multi-processor hosts. | |
| * Return type, and name parameter of lt_dlloader_remove are no longer | |
| `const'. | |
| * Name parameter of lt_dlloader_find is no longer 'const'. | |
| * The API for the slist ADT has been updated: slist_new has been replaced | |
| by slist_box; slist_unbox and slist_sort are new; the footprint of | |
| slist_remove and slist_fnid have changed; SListCallback and SListCompare | |
| types have been exchanged. See libltdl/slist.c for documentation. | |
| * libltdl is C89 compatible again. lt_dlsymbol type removed, and lt_dlsymlist | |
| structure changed to avoid using C99 flexible arrays. | |
| * Support self dlopening for executables on cygwin and mingw. | |
| * Improved support for linux-gnu/ia64. | |
| * Initial support for s390x-ibm-tpf. | |
| * Fixed some memory leaks in libltdl. | |
| * Improved support for OpenBSD (use rpath instead of hardcoding absolute | |
| file names). | |
| New in 1.9b: 2004-08-29; CVS version 1.5a, Libtool team: | |
| * The /^_?LT_[A-Z_]+$/ 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. | |
| * Bug fixes. | |
| New in 1.5.8: 2004-08-07; CVS version 1.5.7a, Libtool team: | |
| * Support for Intel C++ version 8.0. | |
| * Improved support for OpenBSD. | |
| * Support for xlc on Mac OS X. | |
| * Better support for zsh as /bin/sh. | |
| * Much faster check for command line length on all BSD systems. | |
| * Better Mac OS X/darwin support. | |
| * Bug Fixes. | |
| New in 1.5.6: 2004-04-11; CVS version 1.5.5a, Libtool team: | |
| * Installs libltdl files properly in $prefix/share/libtool/libltdl. 1.5.4 | |
| did not install them at all. | |
| * libltdl correctly guesses the extension for loadable modules again. | |
| New in 1.5.4: 2004-04-03; CVS version 1.5.3a, Libtool team: | |
| * Bug fixes. | |
| New in 1.5.2: 2004-01-25; CVS version 1.5.0a, Libtool team: | |
| * 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 GNU/Linux. | |
| * Recognises the 'R' symbol type on Solaris so read-only symbols can be | |
| exported. | |
| * Bug fixes. | |
| New in 1.5.1: 2003-??-??; CVS version 1.5.0a, Libtool team: | |
| * lt_dlrealloc is an official part of the libltdl API. | |
| * Bug fixes. | |
| New in 1.5: 2003-04-14; CVS version 1.4e, Libtool team: | |
| * First stable release of multi-language architecture. | |
| * libtool and libltdl support for Mac OS/X. | |
| * libltdl will now use cygwins dlopen API instead of always forcing | |
| LoadLibrary. | |
| * Support auto-import patch to binutils on cygwin for much improved dll | |
| support. | |
| * Bug fixes. | |
| New in 1.4.3: 2002-10-13; CVS version 1.4.2a, Robert Boehne: | |
| * The libltdl subdirectory now bootstraps correctly with Automake 1.5. | |
| * srcdir != builddir builds with Automake 1.5 work correctly. | |
| * Support for mips-compaq-nonstopux. | |
| * New command line argument, --preserve-dup-deps prevents removal of | |
| duplicate dependent libraries. | |
| New in 1.4d: 2002-01-07; CVS version 1.4c, Libtool team: | |

| 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 | |

| (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. | |

| * 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 | |
| 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: | |
