Now, we no + longer check for a SunCC ABI at configure time, but augment the + postdeps at libtool time based on the current invocation flags on + each call. + +** Changes in supported systems or compilers: + + - /usr/local prefixed rpaths are now added to the link-line on + ia64-hp-hpux*, because the default system runtime loader path does + not contain them. + + - Previously, when using Sun C++ on Solaris or GNU/Linux, `-Cstd -Crun` + flags were added to $postdeps unless CXX or CXXFLAGS contained + `-library=stlport4`. Newer releases have added other compiler flags + that are also incompatible with `-Cstd -Crun`, so now we don't add + them if any of `-std=c++[0-9][0-9]`, `-library=stdcxx4` or + `-compat=g` were found in CXX or CXXFLAGS when the Sun C++ compiler + is detected. + + +* Noteworthy changes in release 2.4.4 (2014-11-29) [stable] + +** New features: + + - Libltdl maintains its own fork of argz, with macros and files in + the LT_ and lt__ namespaces (resp.) where they cannot clash with + client projects' use of gnulib argz. + +** Bug fixes: + + - Installation of 'libtoolize' once again obeys '--program-prefix', + '--program-suffix' and '--program-transform-name' configure options. + + - `libtoolize` doesn't remove any files that it can't reinstall, + including old versions of the snippet directory, and gnulib's + version of the argz module and supporting files. + + - LT_FUNC_DLYSM_USCORE now works correctly on systems that don't + support self dlopen()ing. + +** Important incompatible changes: + + - LT_LIB_DLLOAD no longer prepends -ldl or -ldld to LIBS, causing + duplicate occurrences in libltdl link lines. If you need to + add a library for dlopen() or shl_load() in your Makefile, then + use $(LIBADD_DLOPEN) or $(LIBADD_SHL_LOAD) respectively. If you + are using libltdl, this all happens automatically, and the only + difference you'll see is no more duplicated library names in the + verbose link line. + +** Changes in supported systems or compilers: + + - Preliminary support for tcc on linux*. Although it already worked + sometimes in previous releases, making sure to set LD correctly now + avoids mis-matching GNU ld with tcc: + + ./configure CC=tcc LD=tcc + + - Added -os2dllname option to work around 8 character base name + limit on OS/2. The option has no effect on other systems. + + - Support for DLL versioning, -export-symbols and -export-symbols-regex + on OS/2. + + - Support filename-based shared library versioning on AIX. See manual + for details. + + +* Noteworthy changes in release 2.4.3 (2014-10-27) [stable] + +** New features: + + - Moved to gnulib release infrastructure. + + - M4 is now used for scanning the M4 macros in your configure.ac that + 'libtoolize' looks at to determine what files you want, and where you + would like them installed. This means that you can compose your + version number or any other argument that Libtoolize needs to know at + M4 time using git-version-gen from gnulib, for example. + + - Invoking 'libtoolize --ltdl' no longer maintains a separate autoconf + macro directory in the libltdl tree, but automatically adjusts the + installed libltdl configuration files to share whatever macro + directory is declared by the parent project. (Note: if you were + already sharing a macro directory with AC_CONFIG_MACRO_DIR(ltdl/m4) + or similar, that still works as does any other directory choice). + + - Invoking 'libtoolize --ltdl' no longer maintains a separate auxiliary + scripts directory in the libltdl tree, but automatically adjusts the + installed libltdl configuration files to share whatever auxiliary + scripts directory is declared by the parent project. (Note: if you + were already sharing an auxiliary directory with subproject libltdl + using AC_CONFIG_AUX_DIR(ltdl/config) or similar, that still works as + does any other directory choice). + + - The legacy tests have all been migrated to the Autotest harness. + + - The Autotest testsuite can be run without the especially time consuming + tests with: + + make check-local TESTSUITEFLAGS='-k "!expensive"' + +** Bug fixes: + + - Fix a long-standing latent bug in autom4te include path for autotests + with VPATH builds. + - Fix a long-standing latent bug in libtoolize that could delete lines + from libltdl/Makefile.am in recursive mode due to underquoting in a + sed script. + - Fix a long-standing bug in libtoolize, by outputting the 'putting + auxiliary files in' header with 'libtoolize --ltdl --subproject'. + - Fix a long-standing bug in libtoolize subproject installation, by not + installing a set of autoconf macro files into the parent project if + there is no configure.ac present to use them. + - The libtoolize subproject mode selector is now named '--subproject' + and is equivalent to the implied '--subproject' mode when no other + mode is selected; '--standalone' never worked, and is no longer + accepted. + - Libtool and libtoolize no longer choke on paths with a comma in them. + - In the case where $SHELL does not have the same enhanced features + (e.g. the ability to parse 'var+=append') as $CONFIG_SHELL, libtool + will now correctly fallback to using only vanilla shell features + instead of failing with a parse at startup. + - Correctly recognize import libraries when Microsoft dumpbin is used + as the name lister and extend the dumpbin wrapper to find symbols + in import libraries using the -headers option of dumpbin. Also fix a + bug in the dumpbin wrapper that could lead to broken symbol listings + in some corner cases. + - Use the improved Microsoft dumpbin support to mend preloading of + import libraries for Microsoft Visual C/C++. + - No longer mangle module-definition (.def) files when feeding them to + the Microsoft Visual C/C++ linker via the -export-symbols argument to + the libtool script, thus matching how .def files are handled when + using GNU tools. + - Recognize more variants (e.g. those starting with a LIBRARY statement) + of module-definitions (.def) files when using them instead of a raw + list of symbols to export. + - Fix a long-standing bug when using libtoolize without automake; we + no longer remove install-sh with --force, since it's not a file + libtoolize will reinstall without --install.. + +** Important incompatible changes: + + - GNU M4 is required to run libtoolize in a directory with a + 'configure.ac' (or 'configure.in') that needs tracing to determine + what modes and directories have been specified. + + - The use of the idiosyncratically named 'Makefile.inc' in nonrecursive + libltdl builds is deprecated, although it will be supported for one + more year or until the next release, whichever takes longer. Please + upgrade to the more standard naming of 'ltdl.mk' in keeping with other + GNU projects. + + - libtoolize now behaves consistenty in respect of multiple directory + arguments to ACLOCAL_AMFLAGS and multiple invocations of AC_CONFIG- + _MACRO_DIRS, where the first directory is always selected. Previous + releases took the first ACLOCAL_AMFLAGS argument, but the last + invocation of AC_CONFIG_MACRO_DIRS. + + - The libtoolize program now advises use of the new Autoconf + AC_CONFIG_MACRO_DIRS declaration. If you follow that advice, all + your developers will need at least autoconf-2.70 and automake-1.13 + to rebootstrap your probject. If you still need to support + bootstrap with older Autotools, then you should add the following + to your configure.ac file: + + m4_ifndef([AC_CONFIG_MACRO_DIRS], + [m4_define([AC_CONFIG_MACRO_DIRS], + m4_defn([AC_CONFIG_MACRO_DIR]))]) + + - Overhead of probing for a non-backslash crippled echo equivalent + during initialization of every script has been removed in favor of + trusting that "printf %s\n" works out of the box on all non-museum + host architectures. Manually setting ECHO appropriately in the + build environment will be necessary on some ancient architectures. + +** Changes in supported systems or compilers: + + - Support for bitrig (*-*-bitrig*). + + - Solaris 7 and earlier requires ECHO=/usr/ucb/echo in the build + environment, to build and use libtool. + +New in 2.4.2 2011-10-17: git version 2.4.1a, Libtool team: + +* New features: + + - The --with-pic configure option now supports a list of comma-separated + package names. This can be used to build some static libraries with PIC + objects while building others with non-PIC objects. + + - Initial support for Go, using the gccgo compiler. + + - On Mac OS X .dylib is now tried as well as .so with + lt_dlopenext(). + +* Bug fixes: + + - The generic approximation of the command line length limit (when getconf is + not available) works again. Regression introduced in v2.2.6-39-g9c3d4d8. + - The bug that leaked developer tool paths into the release tarballs + from ./bootstrap is fixed. + - Improved support for the Cuda Compiler Driver (nvcc) on Darwin. + - For GCC LTO support, the -fuse-linker-plugin switch is now also removed + when computing compiler postdeps. + +* Important incompatible changes: + + - The undocumented hardcode_libdir_flag_spec_ld tag variable has been + removed in favor of using hardcode_libdir_flag_spec with $wl set to empty. + +* Changes in supported systems or compilers: + + - Fixes for gfortran on Darwin, XL Fortran on GNU/Linux. + - Support for FreeBSD 1.x (outdated since 1994) has been removed. + +New in 2.4 2010-09-22: git version 2.2.11a, Libtool team: + +* New features: + + - Sysroot support. This allows you to build cross-compiled packages + with the same prefix that will be used on the destination machine, + and still find dependent libraries under the compiler's "sysroot". + Without sysroot support, paths internal to the build system may leak + into the product of the build. + + Sysroot support is disabled unless the --with-sysroot configure + option is passed to configure, because .la files generated with + sysroot support will _not_ be usable in general with older Libtools. + + - 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. + - The fix_srcfile_path variable has been replaced by a more thorough + mechanism triggered by the to_tool_file_cmd variable. + +* 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. Please note that the import library naming + has changed (from foo-2.lib to foo.dll.lib) from when the code lived + in its own git branch. + - Initial support for the NAG Fortran compiler on GNU/Linux. + +* Bug fixes: + + - The 'check-interactive' and 'check-noninteractive' convenience make + targets now also work for the old testsuite. + - Warnings from Autoconf v2.67-36-g1e604ec about incomplete programs + passed to AC_*_IFELSE tests have been fixed. + - On IRIX, the test for -Wl,-exported_symbol now also works with gfortran. + +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. + - The type of the symbol lists variables (lt_*_LTX_preloaded_symbols) has + been fixed in the manual and in a couple of tests to match the actual + implementation. + +* 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). + - Initial support for GCC link-time optimization (LTO) flags. + +* 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 propagate 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: +* Help strings display correctly again. +* Better error messages when library linking fails. +* Better error messages from libltdl when loading fails. +* Better search path management in libltdl with 'lt_dlinsertsearchdir' call. +* Support /lib/w32api in recent cygwin releases. +* Support cross compilation to mingw. +* Support for .rc files (Windows resource compiler). +* Improved handling of mingw gcc. +* Improved handling of $PATH with entries containing spaces. +* Improved support for linking with gcc on aix4* and aix5*. +* Improved support for GCC 3.0. +* Initial support for QNX RTOS, UnixWare 7 and OpenUNIX 8. +* Bug fixes to the OpenBSD port. +* Bug fixes. + +New in 1.4.2: 2001-09-11; CVS version 1.4.1a, 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.
