Development has moved to git.

1 NEWS - list of user-visible changes between releases of GNU Libtool
2
3 New in 2.2.2: 2008-04-01: CVS version 2.2.1a, Libtool team:
4
5 * New features:
6
7 - In compile mode, compiler output occurs in the user locale. This
8 feature has been present in 1.5.26 but not in 2.2.
9
10 * Changes in supported systems or compilers:
11
12 - Initial shared library support for AmigaOS4 on powerpc.
13
14 * Bug fixes:
15
16 - Fix 2.2 regression in libltdl that causes memory corruption upon
17 repeated `lt_dlinit(); lt_dlexit()'.
18 - Fix 2.2 regression in libltdl that skipped the dlopen loader if
19 the system also supports other loaders (e.g., Cygwin, HP-UX).
20 - Fix 2.2 regression in that `libtool --mode=execute CMD ARGS' does not
21 transform ARGS that do not look like shell or C wrappers of libtool
22 programs.
23 - Fix 2.2 regression that kept cross-compiling to w32 from working.
24 - Several testsuite issues have been fixed, thanks to user feedback.
25
26 New in 2.2: 2008-03-01; CVS version 2.1c, Libtool team:
27
28 * Bug fixes:
29
30 - argz.c, lt__dirent.c and lt__strl.c are correctly distributed with
31 parent projects using nonrecursive libltdl.
32 - libtoolize no longer tries to install libtool files when libltdl is
33 used in a non-autoconf parent package.
34 - Don't add the CXX tag to libtool when there is no C++ compiler, even
35 if AC_PROG_CXX sets a default g++ compiler where no such compiler
36 actually exists.
37 - make distcheck DISTCHECK_CONFIGURE_FLAGS=--disable-ltdl-install
38 works again.
39
40 New in 2.1b: 2008-02-01; CVS version 2.1a, Libtool team:
41
42 * Important incompatible changes and obsoleted features:
43
44 - Removed deprecated APIs from libltdl: lt_dlcaller_register,
45 lt_dlhandle_next, lt_dlhandle_find, lt_dlforeach, lt_dlmutex_register,
46 lt_dlmutex_lock, lt_dlmutex_unlock, lt_dlmutex_seterror,
47 lt_dlmutex_geterror, lt_dlmalloc, lt_dlrealloc, lt_dlfree.
48 - The Libtool and libltdl macros and the testsuite now assume a C89
49 environment, consequently do not test for headers such as string.h,
50 strings.h, memory.h any more.
51 - Fix regression in libltdl symbol exports on Cygwin. Side effect:
52 LT_GLOBAL_DATA and LT_SCOPE are now explicitly defined as
53 declspec(dllexport), bypassing auto-export logic on Cygwin.
54 This tracks existing behavior on MinGW.
55 - The libtool script has been optimized a bit for more modern shells.
56 This breaks use of the stdin file descriptor in libtool, and can
57 break if a different shell is used to execute the libtool script
58 than the one it was configured for.
59 - The macros AC_ENABLE_SHARED, AC_DISABLE_SHARED, AC_ENABLE_STATIC, and
60 AC_DISABLE_STATIC have been un-deprecated after deprecation in
61 1.9b.
62 - The macro LT_WITH_LTDL has been renamed to LTDL_INIT.
63 - Fixed a branch-1-5/HEAD regression to only link uninstalled libraries
64 statically with `-static'. In order to compensate for this, there
65 is a new link flag `-static-libtool-libs' to provide the previous
66 `-static' semantics.
67
68 * New features:
69
70 - Fix installation of libltdl so that it does not need Autoconf and
71 Automake installed, in order to be usable in another package. This
72 lifts the restrictions introduced in 1.9b.
73 - Default convenience or installable libltdl builds can optionally
74 be declared using new `convenience' or `installable' options to the
75 LTDL_INIT macro (as an alternative to individual LTDL_CONVENIENCE
76 or LTDL_INSTALLABLE invocations).
77 - New configure-time options to allow libltdl parent project builder
78 to choose between installed and shipped libltdl, when invoking
79 LTDL_INIT: --with-included-ltdl, --with-ltdl-include,
80 --with-ltdl-lib.
81 - New LT_CONFIG_LTDL_DIR macro to specify a different directory name
82 for a convenience libltdl.
83 - libtoolize has been completely overhauled.
84 - `libtoolize --install' now also installs `install-sh'.
85 - New libtoolize options: --non-recursive, --recursive, --subproject.
86 These options control the way libltdl is installed into a package by
87 libtoolize. The new recursive and non-recursive build modes for
88 libltdl don't require a subconfigure any more.
89 The Libtool package itself builds libltdl nonrecursively.
90 - The 'nonrecursive', 'recursive' and 'subproject' libltdl build
91 modes are given as LTDL_INIT options.
92 - New make variable LTDLDEPS for use in output_DEPENDENCIES.
93 - New multi-module-loader safe libltdl handle iteration APIs:
94 lt_dlhandle_iterate, lt_dlhandle_fetch, lt_dlhandle_map.
95 - New lt_dlinterface_register to maintain separation of concerns
96 between modules loaded by different libraries.
97 - New lt_dlopenadvise takes a new lt_dladvise type argument, which
98 lets the caller request local or global symbol visibility from the
99 module loader with lt_dladvise_local and lt_dladvise_global
100 respectively. If neither is given, or if lt_dlopen (or lt_dlopenext)
101 are called, then the system default module symbol visibility is used.
102 - The new lt_dladvise_init/lt_dladvise_destroy based APIs also allow
103 caller requests for a filename extension search with lt_dladvise_ext,
104 and for marking a module unloadable with lt_dladvise_resident.
105 - Allow shell special characters like `$' in source file names, but
106 not in object names, to enhance GCJ support.
107 - An entire new Autotest-based testsuite in addition to the old one.
108 Both testsuites have been made more useful for testing
109 cross-compilers. The new testsuite exposes many more issues, but
110 may also be a little rocky on exotic systems.
111 - In 1.9b, a new variable inherited_linker_flags has been added to the
112 libtool library files. This variable takes flags that should be
113 used by dependent libraries and programs, but that do not fit into
114 `dependency_libs' for both clarity and backward-compatibility.
115
116 * Changes in supported systems or compilers:
117
118 - Removed bitrotted support for xlc on Mac OS X.
119 - Detection of compiler wrappers distcc/ccache and $host_alias prefix.
120 - Basic support for PIE (position-independent executables).
121 - Support for DragonFly BSD, improved support for FreeBSD.
122 - Improved support for GNU/kFreeBSD and GNU/NetBSD.
123 - Support for Interix 3 (Windows SFU) and newer versions.
124 - Support for AIX 6.1.
125 - Improved support for UnixWare.
126 - Initial support for RDOS.
127 - Initial Support for FC (modern Fortran).
128 - Support for Portland Group compiler, the Sun compiler suite on GNU/Linux,
129 and initial support for the IBM compiler suite on GNU/Linux/ppc.
130 - Support for linux-dietlibc (`diet' as well as `diet-dyn', separately).
131 - Building libltdl with a C++ compiler has been undusted.
132 - On (AIX?,) HP-UX, and OpenBSD, hardcoding has been changed to prefer
133 rpath over absolute dependent library names. This fixes DESTDIR
134 installs, among others, on the non-HP-UX/PA systems.
135 - Use of C++ templates together with shared libraries has been
136 improved on some systems and with some compilers, but is still
137 ongoing work. Feedback is desirable here.
138
139 * Bug fixes:
140
141 - Fix libltdl on static platforms.
142 - Search paths with GCC on multilib systems like x86_64 have been fixed.
143 - Fixed a regression that prevented use of libltdl without autotools.
144 - Fix error with -version-info on systems with version_type=none, such
145 as BeOS.
146 - Fix symbol exporting for cases where command line length limits are
147 exceeded.
148 - Improve linking with C++ libraries on Solaris with Sun compiler.
149 - Fix installation of libraries that are required by installation
150 commands such as `ln' or `rm'.
151 - More robust parsing of mangled `.la' files inside libltdl, fixing a
152 possible overrun and a crash due to memory exhaustion.
153 - Fix compile command line for gcj on MinGW.
154 - Some configure variables have been renamed to fix caching:
155 lt_prog_compiler_pic_works to lt_cv_prog_compiler_pic_works
156 lt_prog_compiler_static_works to lt_cv_prog_compiler_static_works.
157 - Fix 1.9b regression: lt_dlopen(NULL) works on AIX again.
158 - Loads of smaller bug fixes.
159
160
161 New in 1.9f: 2004-10-23; CVS version 1.9e, Libtool team:
162 * Fix a regression in 1.9d, where ECHO was always set to 'echo' and the
163 backslash quoting tests were never run.
164 * Fix a regression in 1.9d, where progpath was used for --no-reexec before it
165 was set.
166 * Fix a regression in 1.9d, which required an installed automake to build the
167 bootstrapped tarball.
168 * Fix hanging bug on MinGW.
169
170 New in 1.9d: 2004-10-03; CVS version 1.9c, Libtool team:
171 * If non-pic objects were not compiled, and libtool is called in link mode,
172 libtool no longer silently creates an empty archive, but rather falls
173 back to pic objects.
174 * When compiling C glue code with $LTCC, libtool now saves the setting of
175 $compiler_flags from the C tag, and passes those flags to $LTCC.
176 * libtool no longer dies when concurrently creating directories with
177 `make -j' on multi-processor hosts.
178 * Return type, and name parameter of lt_dlloader_remove are no longer
179 `const'.
180 * Name parameter of lt_dlloader_find is no longer 'const'.
181 * The API for the slist ADT has been updated: slist_new has been replaced
182 by slist_box; slist_unbox and slist_sort are new; the footprint of
183 slist_remove and slist_fnid have changed; SListCallback and SListCompare
184 types have been exchanged. See libltdl/slist.c for documentation.
185 * libltdl is C89 compatible again. lt_dlsymbol type removed, and lt_dlsymlist
186 structure changed to avoid using C99 flexible arrays.
187 * Support self dlopening for executables on cygwin and mingw.
188 * Improved support for linux-gnu/ia64.
189 * Initial support for s390x-ibm-tpf.
190 * Fixed some memory leaks in libltdl.
191 * Improved support for OpenBSD (use rpath instead of hardcoding absolute
192 file names).
193
194 New in 1.9b: 2004-08-29; CVS version 1.5a, Libtool team:
195 * The /^_?LT_[A-Z_]+$/ namespace is now reserved for Libtool's own macros.
196 If you have any shell variables in this namespace they will need to be
197 renamed. If you have any macros in this namespace please rename them to
198 prevent any possible future clash with libtool supplied macros.
199 * New LT_PREREQ macro for specifying minimum libtool requirement.
200 * New LT_INIT interface replaces AC_PROG_LIBTOOL, AC_ENABLE_SHARED,
201 AC_DISABLE_SHARED, AC_ENABLE_STATIC, AC_DISABLE_STATIC,
202 AC_ENABLE_FAST_INSTALL, AC_DISABLE_FAST_INSTALL, AC_LIBTOOL_DLOPEN,
203 AC_LIBTOOL_WIN32_DLL and AC_LIBTOOL_PIC_MODE. Use autoupdate to modernise
204 your configure.ac files after installing this release.
205 * New LT_LANG interface to enable libtool support for a specific language.
206 * Language support is now only included if your configure.ac enables it,
207 either through a call to AC_PROG_CXX etc. or LT_LANG.
208 * The libtool script will complain if it was built from mismatched ltmain.sh
209 and libtool m4 macro versions.
210 * Like automake, libtoolize no longer installs config.guess and config.sub by
211 default. Use new --install option to get the old behaviour.
212 * libtoolize no longer supports the --ltdl-tar option.
213 * libtool script is now created by config.status. Instead of interrogating
214 `./libtool' from configure.ac after calling AC_PROG_LIBTOOL, use the
215 variable names directly.
216 * libltdl is no longer a self-contained package, and shares configury with
217 the top level directory now.
218 * Shared objects (.lo) are no longer created when `-static' is passed in
219 compile mode.
220 * New compile mode option `-shared' prevents creation of static objects (.o).
221 * New link mode option `-shared' creates only shared libraries at link time.
222 * If you configure libtool with --disable-shared (or if libtool does not
223 support shared libraries on your platform) trying to build a library using
224 `-shared' is a fatal error.
225 * New link mode option `-weak' tells libtool when not to propogate dependency
226 libraries from dlpreopened modules.
227 * libtoolize installs libtool.m4, (ltdl.m4 if used,) and various supporting
228 m4 definitions to AC_CONFIG_MACRO_DIR.
229 * Mode inferrence removed, shorthand for choosing modes added.
230 * Specifying -allow-undefined is now an error.
231 * Speed up max_cmd_len check.
232 * libltdl can now preopen modules from within a library, and libtool will
233 accept -dlpreopen options when linking either a shared library or a
234 convenience library.
235 * New function in libltdl: lt_dlhandle_find provides access to module handles
236 by module name.
237 * New function in libltdl: lt_dlpreload_open opens all preloaded modules.
238 * libltdl no longer loads shared libraries with global symbol resolution,
239 this caused problems when the symbols were intended to be overriden further
240 up the stack; it is also not recommended practice.
241 * New function in libltdl: lt_dlhandle_first, primes handle iterations (using
242 lt_dlhandle_next) to filter by module interface.
243 * libltdl no longer tries to support multi-threaded programming with
244 lt_dlmutex_register(), which was unusable with POSIX threads anyway.
245 The symbols are deprecated but exported for backwards compatibility.
246 * libltdl no longer uses lt_dlmalloc, lt_dlrealloc and lt_dlfree. The symbols
247 are still exported for backwards compatibility.
248 * The lt_dlinfo struct has a new module field that can be used by dlloaders.
249 * libltdl no longer supports pre-c89 compilers. Some of the pre89 portability
250 functions had compile time bugs in them anyway, so you guys can't have been
251 using it :-)
252 * make install now deletes preexisting $prefix/share/libtool before installing
253 latest files.
254 * Extracting symbols from an import library on cygwin and win32 now works.
255 * Initial support for amigaos-ppc.
256 * Improved support for OpenBSD.
257 * Support for Intel C++ version 8.0.
258 * New support for IBM's xlc and xlc++ on Mac OS X.
259 * Finished support for QNX RTOS.
260 * Bug fixes.
261
262 New in 1.5.8: 2004-08-07; CVS version 1.5.7a, Libtool team:
263 * Support for Intel C++ version 8.0.
264 * Improved support for OpenBSD.
265 * Support for xlc on Mac OS X.
266 * Better support for zsh as /bin/sh.
267 * Much faster check for command line length on all BSD systems.
268 * Better Mac OS X/darwin support.
269 * Bug Fixes.
270
271 New in 1.5.6: 2004-04-11; CVS version 1.5.5a, Libtool team:
272 * Installs libltdl files properly in $prefix/share/libtool/libltdl. 1.5.4
273 did not install them at all.
274 * libltdl correctly guesses the extension for loadable modules again.
275
276 New in 1.5.4: 2004-04-03; CVS version 1.5.3a, Libtool team:
277 * Bug fixes.
278
279 New in 1.5.2: 2004-01-25; CVS version 1.5.0a, Libtool team:
280 * lt_dlrealloc is an official part of the libltdl API.
281 * --tag, --silent and --debug options are preserved and reused when libtool
282 calls itself for relinking etc.
283 * `-pthread' and similar options are honoured when linking shared libraries.
284 * -no-suppress in compile mode shows compiler output for both PIC and non-PIC
285 object compilation.
286 * New link mode option `-precious-files-regex' to prevent accidental removal
287 of files you want to keep, such as test coverage data, from the temporary
288 output directory.
289 * Directories specified in /etc/ld.so.conf are no longer hardcoded on GNU/Linux.
290 * Recognises the 'R' symbol type on Solaris so read-only symbols can be
291 exported.
292 * Bug fixes.
293
294 New in 1.5.1: 2003-??-??; CVS version 1.5.0a, Libtool team:
295 * lt_dlrealloc is an official part of the libltdl API.
296 * Bug fixes.
297
298 New in 1.5: 2003-04-14; CVS version 1.4e, Libtool team:
299 * First stable release of multi-language architecture.
300 * libtool and libltdl support for Mac OS/X.
301 * libltdl will now use cygwins dlopen API instead of always forcing
302 LoadLibrary.
303 * Support auto-import patch to binutils on cygwin for much improved dll
304 support.
305 * Bug fixes.
306
307 New in 1.4.3: 2002-10-13; CVS version 1.4.2a, Robert Boehne:
308 * The libltdl subdirectory now bootstraps correctly with Automake 1.5.
309 * srcdir != builddir builds with Automake 1.5 work correctly.
310 * Support for mips-compaq-nonstopux.
311 * New command line argument, --preserve-dup-deps prevents removal of
312 duplicate dependent libraries.
313
314 New in 1.4d: 2002-01-07; CVS version 1.4c, Libtool team:
315 * Help strings display correctly again.

325 * Improved support for GCC 3.0.
326 * Initial support for QNX RTOS, UnixWare 7 and OpenUNIX 8.
327 * Bug fixes to the OpenBSD port.
328 * Bug fixes.
329
330 New in 1.4.2: 2001-09-11; CVS version 1.4.1a, Gary V. Vaughan:
331 * libltdl now builds on solaris again
332 * diagnose and warn about not-quite-working combinations of gcc and
333 ld on solaris.
334 * Improved OpenBSD support.
335 * Improved cygwin support.
336 * Bugfixes.
337

347 * Now bootstraps with autoconf-2.50 and automake-1.4-p4.
348 * Always try to build at least a static lib, even if both static and
349 shared libs were disabled.
350 * Full support for C++ compiler.

358
359 New in 1.4: 2001-04-25; CVS version 1.3e, Libtool team:
360 * Support for aix5*.
361 * Bugfixes.
362
363 New in 1.3d: 2001-04-02; CVS version 1.3c, Libtool team:
364 * ltconfig is no more. Generation of libtool happens directly from
365 the configure file.
366 * Multithread safe with lt_dlmutex_register callback registration.
367 * New -no-install flag to avoid the use of executable wrapper scripts.
368 * New --with-pic, -prefer-pic and -prefer-non-pic flags to control

375 specific data in handles.
376 lt_dlcaller_register, lt_dlcaller_set_data and lt_dlcaller_get_data provide
377 management for user storage of per module data.
378 lt_dlloader_next, lt_dlloader_name, lt_dlloader_find, lt_dlloader_add and
379 lt_dlloader_remove can be used for adding new types of module loaders.
380 lt_dladderror, lt_dlseterror integrate user module loaders with lt_dlerror.

392 * Many bugfixes (especially in libltdl)
393
394 New in 1.3b: 1999-07-02; CVS version 1.3a, Libtool team:
395 * Complete inter-library dependencies support. It's now possible
396 to link libtool libraries against other libtool libraries.
397 * Libtool is able to find already-installed libtool libraries,
398 even if they were moved out of their installation directory.
399 * New "-Wc,flag" and "-Xcompiler flag" flags to pass flags
400 directly to the compiler

472
473 New in CVS version 1.2g, Libtool team:
474 * AM_PROG_LIBTOOL is smaller and faster
475 * AC_LIBTL_L_WIN32_DLL is required in configure.in for libtool to
476 attempt to build dlls on win32 hosts

489 New in 1.2f: 1999-03-15; CVS version 1.2e, Libtool team:
490 * libtool will correctly link uninstalled libraries into programs
491 and prefer uninstalled libraries to installed ones
492 * Library paths that are in the system default run-time search path
493 are no longer hardcoded into executables.
494 * New fast installation mode, which links the final executable
495 in order to avoid relinking during installation.
496 Programs in the build-tree are relinked when executed.
497 * New AC_DISABLE_FAST_INSTALL macro to set the default for
498 the fast-install mode to disabled
499 * New -export-symbols-regex flag, to export symbols selectively by
500 a regular expression
501 * Support -R for specifying run-time path of programs and library dependencies
502 * New -avoid-version option to avoid versioning for libraries
503 * libtool module names no longer need to have a "lib" prefix
504 (requires automake 1.4).
505 * New -thread-safe flag, to build thread-safe libraries
506 * Major improvements in libltdl: API documentation, installable version,
507 support for module search paths, support for lt_dlopen(0),
508 can be embedded into packages as a tar file (libltdl.tar.gz),
509 dynamic buffer allocation and buffer overflow checks,
510 new macro LTDL_SET_PRELOADED_SYMBOLS() which must be used in the
511 main program, dynamic memory allocation functions are user-defineable
512 * New AC_LIBLTDL_CONVENIENCE and AC_LIBLTDL_INSTALLABLE macros, to select
513 convenience and/or installable versions of libltdl.
514 * libltdl is now built and installed unless --disable-ltdl-install
515 * New "-dlopen self" flag for dlopening the executable itself
516 * New AC_LIBTOOL_DLOPEN macro to check for dlopen support,
517 required if you use -dlopen or -dlpreopen

527 * Support for IRIX library versioning.
528 * New demos and tests
529 * Various bugfixes
530
531 New in 1.2d: 1998-12-16; CVS version 1.2c, Libtool team:
532 * libtool will correctly link already-installed libraries into programs.
533 * New -module flag, to create loadable modules.
534 * New libltdl, a small library for portable dlopening of modules.
535 It is still undocumented, but you can already find some examples in:
536 * New mdemo directory, with tests of -module and dlopening examples.
537 Be aware that libltdl is only known to work on a few platforms such as
538 GNU/Linux and Solaris2. Some mdemo tests are known to FAIL on several
539 other platforms; please ignore these failures by now (or work to fix
540 them :-).
541 * Inter-library dependencies patch finally integrated, but there's
542 still much porting to do. See PORTING for details (some plans for the
543 future in mail/deplibs in the CVS tree).
544 * New option -export-symbols to control symbol exporting when possible.
545 * Fixed -export-dynamic problem with C++ programs in egcs 1.1.
546 * New dlpreopen structure.
547 * libtool now supports `-c -o' and subdirectories in sources and
548 target object names even in platforms whose compilers do not support
549 this. In this case, file locking occurs to avoid problems with
550 parallel builds.
551 * New `echo' variant that should fix most problems with long command
552 lines and broken printf programs.
553 * Support for DG/UX, UnixWare 7.x and FreeBSD 3.0, and improved
554 support for Microsoft Windows
555 * Various bugfixes
556 * We now have anonymous CVS access to GNU libtool. CVSROOT is
557 :pserver:anoncvs@anoncvs.gnu.org:/gd/gnu/anoncvsroot. The password
558 is empty. The directory is libtool. Check our home-page at
559 http://www.gnu.org/software/libtool/libtool.html for details.
560 * Alexandre Oliva, Thomas Tanner and Gary V. Vaughan have taken over
561 the maintenance of libtool.
562 * Arguments to ltconfig have been changed to allow creation of a
563 libtool C program, totally unusable as of this release.
564
565 New in 1.2b - 1998-07-01, Gordon Matzigkeit:
566 * Libtool needs a new maintainer, since Gordon Matzigkeit has quit.
567 If you think you can do the job, send mail to bug-libtool@gnu.org.
568 * Bug fixes.
569 * Support for libtool convenience archives.
570
571 New in 1.2a - 1998-04-19, Gordon Matzigkeit:
572 * Bug fixes.
573 * ltconfig accepts an `--output' option to specify the name of the
574 generated libtool.
575 * New `--debug' flag to turn on shell script tracing for libtool,
576 libtoolize, and ltconfig.
577 * Added `libtool --config' to print out all configuration variables.
578 * Support for *-*-hpux11*.
579
580 New in 1.2 - 1998-03-20, Gordon Matzigkeit:
581 * Minor bug fixes to provide a stable public release.
582 * Libtool no longer cseses Solaris printf to barf due to silly
583 2110-byte static buffers.
584
585 New in 1.1 - 1998-03-08, Gordon Matzigkeit:
586 * Bug fixes.
587 * http://www.profitpress.com/libtool/ is libtool's homepage.
588 * `AM_PROG_LIBTOOL' supports turning shared or static libraries off
589 with the `--enable-shared=PKGS' and `--enable-static=PKGS' configure
590 flags. See (libtool)AM_PROG_LIBTOOL.
591 * Use the `AM_DISABLE_SHARED' or `AM_DISABLE_STATIC' macros if you
592 wish to modify the default behaviour of `AM_PROG_LIBTOOL' for your
593 package.
594 * New rules for `AM_PROG_LD' to use gcc's `-print-prog-name' flag in
595 order to find ld, if possible.
596 * Suppress duplicate compiler output during `compile' mode.
597 * Deleted `dlname' mode. Dlopen applications should only use the
598 runtime search method described in (libtool)Finding the dlname.
599 * Experimental support for dynamically loaded modules, even on
600 static-only platforms, via new `-dlopen' and `-dlpreopen' link
601 flags.
602 * `compile' mode honours the `-static' flag to prevent libtool
603 from building PIC objects.
604 * New `execute' mode to support debugging uninstalled libtool
605 libraries and executables.
606 * `-allow-undefined' is now the default. You can use `-no-undefined'
607 to declare that a shared library is completely self-contained.
608 * Inter-library dependencies are automatically handled when linking
609 against an uninstalled `.la' file.
610 * New `-all-static' flag to prevent any dynamic linking. The regular
611 `-static' flag now just prevents dynamic linking of libtool libraries.
612 * New `-release' flag to encode release numbers into libtool
613 libraries. This breaks binary compatibility, but is useful for
614 libraries whose interfaces change very frequently. See
615 (libtool)Versioning.
616 * The `-rpath' flag can be used to hardcode absolute directories when
617 linking executables using libtool.
618 * New robust quoting code to handle any metacharacters passed in
619 arguments to libtool commands.
620 * Full support for broken collect2 on AIX 3. Shared libraries
621 can now be built with all working versions of GCC on AIX.
622 * Shell script speed optimizations for old and buggy /bin/sh systems,
623 such as HP-UX 9 and SunOS 4.1.4.
624 * Maybe use `_libs' as a temporary libtool directory instead of `.libs'
625 in order to cope with MS-DOS filenames.
626 * Portability fixes for Windows NT.
627 * Refuse to create libtool libraries that don't begin with `lib'.
628 This allows us to correctly handle OSes that don't have the `lib'
629 prefix by default, such as OS/2.
630 * Support for *-*-amigaos*, *-*-os2*, *-*-sysv4.2uw2*, and *-*-uts4*.
631
632 New in 1.0 - 1997-07-08, Gordon Matzigkeit:
633 * Bug fixes.
634 * Better configuration test to find the system linker. The old test
635 was failing because people frequently install GNU ld, but don't
636 necessarily configure GCC to use it.
637 * Automake support for Libtool now uses the LTLIBRARIES primary. See
638 the Automake documentation for more information.
639 * Added new `--disable-static' flag to disable building static
640 libraries on platforms that have shared libs.
641 * New `-allow-undefined' link flag to build shared libs that contain
642 references to unresolved symbols.
643 * Removed all support for creating static-only libraries.
644 * Basic support for dynamically loaded modules: new `-export-dynamic'
645 linking flag and corresponding `dlname' mode.
646 * New `--features' flag to display configured libtool attributes.
647 * Added support for installing libtool objects, both in absolute and
648 relative directories.
649 * Support *-*-linux-gnu* as an alias for *-*-linux*.
650 * Support for *-*-openbsd* and *-*-freebsd3*.
651
652 New in 0.9 - 1997-02-03, Gordon Matzigkeit:
653 * Bug fixes.
654 * The libtool demo now uses the libm cos(3) function, to demonstrate
655 inter-library dependencies.
656 * The PLATFORMS file has been moved to doc/platforms.texi.
657
658 New in 0.8 - 1997-01-26, Gordon Matzigkeit:
659 * Bug fixes, and more documentation.
660 * Basic support for other language compilers (C++, Fortran, and
661 preprocessed assembler).
662 * Libtool is now more persistent when linking with the `-static'
663 flag fails.
664 * New test for hardcoding system linkers, to verify that libtool
665 neither creates incorrect binaries, nor takes unnecessary
666 precautions while linking against uninstalled shared libraries.
667 * For clarity, the demo subdirectory no longer uses ansi2knr, and has
668 been rewritten to avoid ANSI-only constructs.
669 * Support for *-*-irix5, *-*-irix6*, and *-*-sco3.2v5*.
670
671 New in 0.7 - 1996-12-08, Gordon Matzigkeit:
672 * Total rewrite of libtool, along with a new model for library building.
673 * Completely rewritten documentation for the new paradigm.
674 * Sane handling of broken system linkers, such as the ones on AIX
675 and HP-UX.
676 * configure mode is now a separate program, `ltconfig'
677 * The libinfo helper script has been incorporated into the main
678 libtool program.
679 * Automatic mode guessing, based on the command line.
680 * Full support for Automake 1.2 (including ansi2knr features).
681 * Support to create reloadable objects using link mode.
682 * Support for new `-static' linking flag.
683 * Support for stripping libraries during installation.
684 * Library version information is now passed on the command line, not
685 through a version file.
686
687 Version 0.6 was never released.
688
689 New in 0.5:
690 * Disabled install-progs until next version, when it will be correctly
691 implemented.
692 * Clearer library versioning documentation. See (libtool)Versioning.
693 * Renamed gm_PROG_LIBTOOL to AM_PROG_LIBTOOL
694 * Libtool now creates pseudo-objects named foo.lo and pseudo-archives named
695 libfoo.la instead of foo.o and libfoo.a. See the documentation.
696 * libtool compile doesn't interfere with user CFLAGS if they don't
697 conflict with the current objtype. From Karl Berry.
698 * Created new libinfo helper script.
699 * libversion.in files are obsolete -- libtool uses libinfo to read the
700 new LIBINFO files.
701 * Libtool is better at finding its config file and helper scripts.
702 * Support for *-*-gnu*
703
704 New in 0.4:
705 * Bug fixes and new regression tests
706 * On unsupported configurations, ``libtool configure'' demotes OBJTYPES to
707 `standard' instead of aborting
708 * Added new object type, `t', for tcov(1) support
709 * Support for *-*-aix3*, *-*-aix4*, *-*-hpux10*, *-*-osf3*, and *-*-solaris2*
710
711 New in 0.3:
712 * Bug fixes and new regression tests
713 * Added new uninstall-libs mode
714 * Added a host argument to configure mode
715 * Fixed debugging/hyper-optimizing flags conflict (from Karl Berry)
716 * Support for --no-whole-archive when needed by GNU ld (from Ulrich Drepper)
717 * Implementation of --enable-linktype, --enable-profile, --enable-shared,
718 --enable-static in gm_PROG_LIBTOOL macro
719 * New `libtoolize' program (modeled after GNU gettext's `gettextize') to help
720 conversion to libtool
721 * New ABOUT-LIBS document for inclusion with libtool-supported packages
722
723 New in 0.2:
724 * Support for *-*-linux
725 * Better checking for GNU ld
726 * Reimplemented the config file so that it corresponds more closely to the
727 variables listed in (libtool)Porting Libtool.
