1997-12-19 Gordon Matzigkeit <gord@profitpress.com> * ltmain.in: Don't forget to quote the CDPATH substitution. From Tor Lillqvist. 1997-12-18 Gordon Matzigkeit <gord@profitpress.com> * ltconfig.in, ltmain.in (CDPATH): Unset this environment variable so that HP-UX shells, at least, don't print out the directory name after a `cd' command. From Tor Lillqvist. 1997-12-10 Gordon Matzigkeit <gord@gnu.org> * demo/Makefile.am (hardcode): Change a bunch of references to `$(LIBS)' to `-lm', since we no longer put -lm in LIBS. * demo/configure.in: Delete the test for libm, since it is standard on every system. * demo/Makefile.am (libhello_la_LDFLAGS): Change to include -lm, in accordance with new inter-library dependency code. * ltmain.in (dependency_libs): Added to help people link programs without having to explicitly specify inter-library dependencies. * ltconfig.in (COLLECT_NAMES): Oops... I forgot to apply the AIX 3 restriction to the generated libtool script. Reported by Stefan Westerfeld. 1997-12-05 Gordon Matzigkeit <gord@gnu.org> * ltconfig.in (thisdir): Quote $echo in the generated libtool script for HP-UX. From Markus F.X.J. Oberhumer. * ltmain.in (link): Recognize the `.s' suffix. From Markus F.X.J. Oberhumer. * ltconfig.in (link_static_flag): Don't quote ${wl} on HP-UX because link_static_flag is never evaled. From Eric Backus. * tests/suffix.test (extensions): Recognize `.s'. From Markus F.X.J. Oberhumer. 1997-12-01 Gordon Matzigkeit <gord@gnu.org> * demo/Makefile.am (helldl_DEPENDENCIES): Add `libhello.la' to our dependencies so that parallel builds work correctly. From Jim Meyering. * Makefile.am ($(srcdir)/ltconfig, $(srcdir)/ltmain.sh): Rewrite these rules so that they are parallelizable. Reported by Jim Meyering. * ltconfig.in (ltecho): We need special handling to quote the `echo' variable itself. From Alexandre Oliva. 1997-11-29 Gordon Matzigkeit <gord@gnu.org> * ltconfig.in (COLLECT_NAMES): Enable this workaround for a broken collect2 only on AIX 3. This avoids problems on other AIX versions. Reported by Stefan Westerfeld. * ltmain.in, ltconfig.in (finish_eval): Variable like finish_cmds, except it is a single command which is evaled, and not shown. * ltconfig.in: Port to AmigaOS. From Joop van de Wege. * ltmain.in (echo): Delete preamble to check for a working echo, since we just use the one included in the generated libtool. * ltconfig.in (echo): Include this definition in the generated libtool script. 1997-11-28 Gordon Matzigkeit <gord@gnu.org> * ltconfig.in, libtool.m4 (NM): Add /usr/ccs/bin to the PATH before checking. From Kaveh R. Ghazi. (NM): Delete an extraneous egrep from ltconfig. * ltconfig.in (finish_cmds): Change back to using `ldconfig -n'. This makes Linux behave like other systems, which is more in line with what libtool needs. 1997-11-27 Gordon Matzigkeit <gord@gnu.org> * ltmain.in: Change a whole bunch of `progname' variables to `modename'. This is for clarity, and to fix a tiny typo in finish mode. * libtool.spec (Name, Version): Ditto. * configure.in (AM_INIT_AUTOMAKE): Use PRCS to automatically generate the proper package name and version number. * ltconfig.in (gnu_ld_acts_native): Treat GNU ld like the native linker on SunOS 4.x. Suggested by Alexandre Oliva. (deplibs): Change the defaults all over, since most systems cannot handle inter-library dependencies. * libtool.m4, ltconfig.in (NM): Only look at the first line of the output from NM when determining whether it supports a command line option. This prevents false positives on OSes which ignore invalid flags, like HP-UX, which prints `nm: unknown option "B" ignored'. Reported by Kaveh R. Ghazi. * ltconfig.in (finish_cmds): On Linux, update ld.so.cache by removing the `-n' flag from ldconfig. Suggested by Kenneth Albanowski. * Makefile.am (maintainer-checkin, maintainer-release): New commands to reap the full benefit of using PRCS to maintain libtool version numbers. * ltconfig.in, ltmain.in (global_symbol_pipe): Explicitly cast all addresses to __ptr_t. This fixes a bug due to a strict IRIX compiler. Suggested by Kaveh R. Ghazi. 1997-11-23 Gordon Matzigkeit <gord@gnu.org> * ltmain.in (echo): For aesthetics, avoid using `$echo' when `echo' will do *exactly* the same thing. This prevents ugly `printf %s\n timestamp > some.lo' commands from appearing in the libtool output. (link): Delete the `-allow-undefined' flag because it is now the default. Make `-no-undefined' in order for people to declare that a library is entirely self-contained. This prevents maintainers from accidentally creating shared libraries that won't work on AIX. Reported by Stefan Westerfeld and Danny Backx. * ltconfig.in (echo): Use an echo variable, just as in ltmain.in, because we need it for quoting substitutions. For most of the script, though, use the default echo, just like Autoconf does. Without this patch, character \001 ends up in global_symbol_pipe. Reported by Lars Hecking and Jürgen Fluk. * ltmain.in (echo): Set default to `echo=echo'. Ooops. That's what you get for testing obscure code paths and forgetting to revert to the original version. Reported by Danny Backx. 1997-11-14 Gordon Matzigkeit <gord@gnu.org> * ltconfig.in (hardcode_libdir_flag_spec): Set to `-R' for FreeBSD 2.2. From Sean Kelly. (postuninstall_cmds, old_postuninstall_cmds): Commands to run after uninstall mode deletes the libraries. Suggested by Joop van de Wege. (export_dynamic_flag_spec): On HP-UX, add the `${wl}-E' export_dynamic_flag_spec. Reported by Matthias Hoelzer. 1997-11-11 Gordon Matzigkeit <gord@gnu.org> * ltconfig.in, ltmain.in (sed_quote_subst): Oops. We forgot to quote backticks. Reported by Joop van de Wege. * tests/quote.test: Add backticks to the backslashify test. 1997-11-09 Gordon Matzigkeit <gord@gnu.org> * ltconfig.in (symcode): On IRIX, don't extract undefined symbols. When a function is inlined by G++, references to it are still marked as undefined in the object file. This means that our symbol file causes undefined references, because there are actually no matching global symbols. Reported by Paul Kendall. 1997-11-08 Gordon Matzigkeit <gord@gnu.org> * ltconfig.in: Don't forget to redirect the COLLECT_NAMES libtool script fragment to the generated libtool, rather than to stdout. 1997-11-07 Gordon Matzigkeit <gord@gnu.org> * libtool.m4 (LD): Add a more sophisticated test to determine the ABI flag on IRIX 6. Suggested by Lars Hecking and Ian Lance Taylor. * ltconfig.in, ltmain.in (COLLECT_NAMES): Only export this variable if we are running under AIX. Otherwise, we tickle a g++ bug under IRIX. From Paul Kendall. * Change bug reporting address to <bug-libtool@gnu.org>. * ltconfig.in (allow_undefined_flag): OSF/1 3.x also requires a wildcard argument to `-expect_unresolved'. From Stephan Kulow. 1997-11-06 Gordon Matzigkeit <gord@gnu.org> * ltmain.in (link): Use libname_spec. * ltconfig.in (pic_flag): Somehow, the HP-UX pic_flag (`+Z') was dropped between libtool-1.0 and now. Add it back in. Reported by Akim Demaille. Integrated more patches for OS/2. From Jeff Freedman. (libname_spec): New variable for OSes that don't require their libraries to look like `libNAME.a'. * ltmain.in (link): Only use global_symbol_pipe if it has been defined. From Stephan Kulow. * ltconfig.in (global_symbol_pipe): Protect C fragment under C++ compilers. From Stephan Kulow. * Makefile.am ($(srcdir)/acinclude.m4, $(srcdir)/demo/acinclude.m4): Change rules to use LN_S so that they can be run on any system. * ltconfig.in (archive_cmds): For NetBSD, don't include deplibs. From Dieter Baron. * ltmain.in (mkdir): Check that the directory doesn't exist before we exit with error, so that we don't get races during parallel builds. From H.J. Lu. (fbsd_hideous_sh_bug): Apparently, some FreeBSD /bin/sh's have a bug that will empty base_compile unless we do this dummy assignment. From Marc van Kempen. 1997-10-22 Gordon Matzigkeit <gord@gnu.org> * libtool.m4 (libtool_shared, libtool_static): Fixed logic error to reenable override of libtool's defaults by setting enable_shared or enable_static in configure.in. Reported by Tom Tromey and Stephan Kulow. * ltmain.in (link): Add explicit support for compiler options that begin with `+'. Reported by Aubert Pierre. 1997-10-20 Gordon Matzigkeit <gord@gnu.org> * ltmain.in: Silly me. Change a bunch of occurances of "* $dir *" into *" $dir "*. * ltconfig.in (pic_flag): PIC is the default for AIX. From Mark Kettenis. It is also the default for OSF/1. * demo/Makefile.am (objdir): Quote double-quotes. From Mark Kettenis. * ltconfig.in (global_symbol_pipe): This variable is not double-evaled, so it should not be double quoted. From Mark Kettenis. 1997-10-19 Gordon Matzigkeit <gord@gnu.org> * ltconfig.in (LD): Same as below. * libtool.m4 (LD): Set LD if we discover an absolute path to GNU ld. This prevents breakage when `$CC -print-prog-name=ld' returns an absolute directory name. Reported by Ulrich Drepper. * ltconfig.in: Port to OS/2 using EMX. From Jeff Freedman. * ltmain.in (link): Use old_archive_from_new_cmds. * ltconfig.in (old_archive_from_new_cmds): New variable to support DLL libraries. * ltmain.in (link): Only `eval' export_dynamic_flag_spec if it is not empty. Reported by Stephan Kulow. 1997-10-18 Gordon Matzigkeit <gord@gnu.org> * ltconfig.in (objdir): Use the .libs directory on all systems for which that name is valid, and _libs on the others (like MS-DOS). Suggested by Juergen Erhard. 1997-10-14 Gordon Matzigkeit <gord@gnu.org> * ltmain.in (link): Added a bit more inter-language support to the symbol file generation process. Instead of complaining about unrecognized argument suffices, pass them to the linker. This prevents libtool from barfing on mandatory arguments to linker flags. Reported by Michael Tiemann. 1997-10-09 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltmain.in (link): Change the wrapper script to follow symlinks in order to find thisdir. This should put the final nail in the coffin for problems with wrapper scripts. From Ian Lance Taylor. 1997-10-07 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltmain.in: Change a few `$echo' commands into `$show' to make --silent mode behave as advertised. * ltconfig.in (allow_undefined_flag): On OSF/1 4.x, use `-expect_unresolved \*'. From Christian Mondrup. * ltmain.in (install): Change install mode to allow a specified /bin/sh argument at the beginning of the install_prog. Also, specify the shell to run when invoking libtool recursively for finish mode. From Chris Provenzano. * libtool.m4 (LIBTOOL): Change definition to include $(SHELL). From Chris Provenzano. * ltconfig.in: Port to UTS 4.x. From Alistair Crooks. * demo/Makefile.am (hc-libflag): Add rules to make this binary for hardcode.test. * tests/hardcode.test (hardcode_libdir_flag_spec): Check the hardcoding properties of the flag_spec, too. 1997-09-24 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltconfig.in (LD): As with libtool.m4, don't override LD. Do a whole bunch of ac_t quoting. 1997-09-24 Ian Lance Taylor <ian@cygnus.com> * libtool.m4 (AM_PROG_LD): Don't override LD in the environment. 1997-09-21 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * libtool.m4, ltconfig.in (NM): Arguments to the for loop must be whitespace separated. This fixes a bug under FreeBSD's /bin/sh. From George Scott. * tests/defs, tests/Makefile.am (clean-local): Change =inst to _inst to fix portability on MS-DOS. From Robert Hoehne. 1997-09-20 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltmain.in (deplibs): When building shared libraries, always add -lc to deplibs. Reported by Andreas Jellinghaus. 1997-09-15 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltconfig.in, ltmain.in (COLLECT_NAMES): If the COLLECT_NAMES environment variable has not been set, set it to empty. This apparently fixes the AIX bug with GCC's collect2. Reported by Mark Kettenis. * demo/Makefile.am, ltmain.in, tests/hardcode.test (objdir): Changed objdir variable .libs to _libs. This is another MS-DOS portability fix. Suggested by Robert Hoehne. * tests/hardcode.test (objdir): New variable to simplify change from .libs to _libs (MS-DOS portability fix). 1997-09-13 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltconfig.in, ltmain.in (hardcode_minusL): Fix typo by renaming hardcode_minusL to hardcode_minus_L. Also add FreeBSD hardcode_libdir_flag_spec. From Paul Traina. * ltmain.in (link): Honour multiple `-rpath' flags when linking programs. Suggested by Bengt Martensson. Quote appearances of $echo in the wrapper script. From Alexandre Oliva. * Makefile.am, configure.in, tests/tlibtool: Use ltmain.in instead of ltmain.sh.in. * ltmain.in: Rename ltmain.sh.in to ltmain.in. This fixes a portability problem (on MS-DOS, of all places!). From Robert Hoehne. 1997-09-11 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltmain.sh.in (link): Do not transform libtool objects to regular objects if we did not build old libs. Reported by Tomas Hiller. 1997-09-05 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * demo/Makefile.am (hell_debug_LDFLAGS): Change hell.static to hell.debug in order to reflect the new static linking semantics. * ltmain.sh.in (link): Add new `-all-static' flag to prevent all dynamic linking. The old `-static' flag just prevents dynamic linking against libtool libraries. Suggested by Bengt Martensson. * ltconfig.in (with_gnu_ld): Add a test to make sure that we are actually using GNU ld. This fixes an inconsistency when running ltconfig without using libtool.m4. Reported by Ulrich Drepper. (global_symbol_pipe): Delete symbols that are not valid C identifiers. Reported by Johan Danielsson and Bengt Martensson. * tests/demo-exec.test, tests/demo-inst.test: Change references from hell.static to hell.debug. * tests/quote.test (echo): Add the same Digital Unix echo test fixes as the ones to ltmain.sh.in from Todd Kover. * tests/if.test, tests/test-e.test (scripts): Add ../lineno to the scripts we check. * tests/if.test: Check for accidental use of test X$something rather than test "X$something". 1997-09-04 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltmain.sh.in (echo): Quote all the uses of `echo' in all eval statements. Reported by Bengt Martensson and Alexandre Oliva. (echo): Need to surround test args with double quotes, or the echo test fails on Digital Unix 4.0. From Todd Kover. 1997-08-28 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltmain.sh.in (echo): Change test to one that uses printf. This works on AIX, which has the same problems that Solaris does, but no working echo program. * tests/quote.test (echo): Change test to version that uses printf. Be less strict about return results. 1997-08-27 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltmain.sh.in (link): Make sure that compile_command and finalize_command are always evaled. Quote any unknown linker flags we need to pass through. (compile): Use quoting for flags we pass. (echo): I hate Sun! The /usr/bin/echo on Solaris handles backslash sequences, which makes it impossible to do backslash quoting using echo and sed. So, we search for an echo that obeys the `echo '\t'` = '\t' equality. Then we use `$echo' everywhere in ltmain.sh. Put tabs back into the ${IFS= } sequences. Emacs untabify is libtool bane. * ltconfig.in: Quote all variable values that may contain metacharacters creating the libtool script. This provides complete protection, so that even single-quotes may appear inside a libtool variable value. * ltmain.sh.in (link): Quote finalize_command before putting it in the wrapper script. * tests/quote.test (echo): Add the test for a non-backslash-mangling echo. 1997-08-26 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltmain.sh.in (sed_quote_subst): Change the quoting procedure again. I think that the new one is robust for *all* characters, including whitespace and metacharacters. * tests/quote.test: New torture test for libtool metacharacter quoting. 1997-08-25 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltmain.sh.in: Change quoting procedure because some shells cannot handle `]' in scan sets. From Ian Dall. 1997-08-22 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltmain.sh.in (execute): Added -dlopen flag handling. Suggested by Alexandre Oliva. 1997-08-21 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltmain.sh.in (link): Change executable wrapper to fix up value of thisdir, as well as progdir, if the $0 path doesn't work. This guarantees that shlibpath_var is set correctly. Add support for execute mode. * ltmain.sh.in (execute): New mode to automatically set shlibpath_var, which allows easy debugging of uninstalled executables and libraries. Suggested by Kenneth Albanowski. 1997-08-20 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * Makefile.am ($(srcdir)/ltconfig): Use lineno. * configure.in: Add AM_PROG_AWK for lineno. * lineno: New program to automatically put line numbers in ltconfig. * libtool.m4, ltconfig.in (AM_PROG_LD): Yet Another Rewrite, which incorporates the results of `gcc -print-program-name=ld'. Suggested by Alexandre Oliva. 1997-08-14 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltmain.sh.in: Accept `--quiet' and `--silent' flags to turn off command echoing. From Juergen A. Erhard. (compile): Recognize the Objective C `.m' extension. From Juergen A. Erhard. (compile): Suppress error output from the second compilation (if any) so that we don't get those frustrating duplicate error messages. * tests/suffix.test (extensions): Added Objective C extension, `.m'. 1997-08-12 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltconfig.in: Added messages to config.log to describe what sort of test we are running. (pic_flag): Added a sanity check for pic_flag. This should fix bugs reported using the cc bundled with HP-UX 10. Suggested by Bruno Haible and Akim Demaille. 1997-08-01 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltmain.sh.in (link): Add -dlopen and -dlpreopen support for libtool objects. This means that dlopened modules no longer need to be shared libraries. * ltconfig.in (pic_flag): GCC on IRIX 6 always builds PIC. Reported by Ian Lance Taylor. * libtool.m4 (LD): Always add `-n32' to the linker if we are using GCC on IRIX 6. Reported by Ian Lance Taylor. 1997-07-30 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * libtool.m4 (AM_PROG_LIBTOOL): Explicitly check enable_shared and enable_static rather than just enableval. This allows configure.in scripts to set their own defaults. Suggested by Tommy Reilly. 1997-07-29 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltmain.sh.in: Add NLS environment variable handling copied from ltconfig.in. Reported by Akim Demaille. (link): If allow_undefined_flag is not supported, then turn on old libraries. Reported by Akim Demaille. * demo/dlmain.c (main): Use dld_preloaded_symbol_count to display a message about the sortedness of the symbol table. * ltconfig.in (nlist): Use an nlist convenience variable, so that code can be shared directly with ltmain.sh.in. * ltconfig.in, ltmain.sh.in (dld_preloaded_symbol_count): Count up the number of symbols in the dld_preloaded_symbols. Set to `-1' if the list wasn't both sorted and counted. This allows applications to do a quick binary search, if they are so inclined. 1997-07-25 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltmain.sh.in (link): Remove code for `-version-file', since it has been long-deprecated. Disable static linking if hardcode_direct is unsupported and there is no working link_static_flag. This provides correct behaviour for all cases on AIX 3, regardless of whether collect2 is broken or not. Reported by Mark Kettenis. * ltconfig.in: Fix typo in test polarity. From Mark Kettenis. 1997-07-24 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltconfig.in (hardcode_direct): Set to `unsupported' if aix3 uses a broken collect2. Adapted out of test results from Mark Kettenis. (link_static_flag): Make sure the link_static_flag actually works with a trivial binary. * ltmain.sh.in, ltconfig.in (export_dynamic_flag_spec): Renamed from export_dynamic_flag because we eval it in ltmain.sh. * ltmain.sh.in (link_static): Don't eval link_static_flag. * demo/dlmain.c (main): Change function prototype to be KNR compatible. From Kaveh R. Ghazi. * ltmain.sh.in (link): Use no_builtin_flag. This works around conflicting definitions of builtin functions with at least GCC. Reported by Kazuhiro Sasayama. * ltconfig.in (no_builtin_flag): New flag to turn off builtin functions when compiling an object file. (pipe_works): Use it. * tests/demo-exec.test (status): Use status variables so that we try to execute all the programs. 1997-07-23 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltconfig.in (pic_flag): According to the libg++ 2.7.2 configure script, DEC alpha CPUs are PIC-only, as well. Reported by Kevin Jacobs. 1997-07-21 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltconfig.in, ltmain.sh.in: Replace all occurances of "sed 'X; Y'" with "sed -e 'X' -e 'Y'". * ltmain.sh.in (link): Finish full integration for `-dlopen' and `-dlpreopen'. Fix two silly typos where I used a compile_command in place of a finalize_command, and vice versa. Change the wrapper script to check a hardcoded path only if the argv[0] method fails. This is a compromise for the previous two patches, and should solve the majority of problems with wrapper scripts. From Kenneth Albanowski. (link): Change a reference to hardcode_libdir_colon_separated to use the new hardcode_libdir_separator variable. * demo/Makefile.am (helldl_LDFLAGS): Add `-export-dynamic' and `-dlpreopen' for building helldl. * demo/dlmain.c (main): Succeed, even if none of the libhello symbols have been preloaded. 1997-07-20 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltconfig.in (global_symbol_pipe): Add `U' to the accepted global symbol types. This means that we will get duplicate symbols, but we'll also be sure to get all global symbols used by the program. * ltconfig.in (pipe_works), ltmain.sh.in (link): Sort and make symbol output unique. 1997-07-19 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltconfig.in (pipe_works): Check to make sure our guessed global_symbol_pipe actually works. * ltmain.sh.in (link): Revert change from Kenneth Albanowski. The wrapper scripts are more reliable when they just use the argv[0] value. Generally, when the argv[0] method doesn't work, the user is trying to do something weird with an uninstalled binary, and should try a different approach. * ltconfig.in, ltmain.sh.in (CC): Always use `$CC' instead of `$cc'. This fixes a FreeBSD bug. Reported by Chuck Robey, and others. 1997-07-14 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltmain.sh.in (link): In wrapper scripts, hardcode the current directory to prevent phony argv[0] values from screwing up our program. From Kenneth Albanowski. 1997-07-13 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * Makefile.am (demo_distfiles): Add demo/dlmain.c to the distribution. 1997-07-12 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * demo/Makefile.am: Add helldl, made from dlmain.c, to demostrate `-dlopen' usage. * demo/dlmain.c: New file to demonstrate preloaded modules. * ltmain.sh.in (link): Add `-dlopen' flag to preload dynamic modules, even on static platforms. Use `$NM' and `$global_symbol_cmd' to extract symbols from required files. (dlname): Delete dlname mode entirely. It is rendered obsolete because the `.la' file format is now a public interface. * ltconfig.in (NM): New variable for BSD-compatible nm program. (global_symbol_cmd): Pipeline to extract global symbols from the nm output. * ltmain.sh.in: The .la file header should depend on `ltmain.sh', not `$PROGRAM'. (link): Make sure $export_dynamic_flag is eval'ed before it is used. * tests/demo-exec.test, tests/demo-inst.test: Check the new helldl program, too. 1997-07-11 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * libtool.spec: New Red Hat Package Manager specification file in order to help people prepare distributions of libtool for Linux. * ltmain.sh.in: Eliminate two accidental uses of the NONE magic value. These were breaking libtool's behaviour when no mode is specified. * tests/nomode.test: New test to make sure there is correct behaviour when we don't specify a mode. 1997-07-08 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * Release 1.0. * ltconfig.in: On SunOS, append /usr/etc to the PATH before running ldconfig; on *BSD, append /sbin. This was done in line with the Linux change suggested by Kenneth Albanowski. * demo/Makefile.am (hardcode_tests): Aesthetic change to alphabetize order of compiling the hardcode tests. * Makefile.am (EXTRA_DIST): Delete README-automake. * README-automake: Remove from distribution. 1997-07-02 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltmain.sh.in (link): In the executable wrapper, strip trailing colons from the shlibpath_var because some ld.so's, notably OpenBSD 2.0's (!), don't parse colon-terminated values correctly. From Tim Pierce. 1997-07-01 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltmain.sh.in, ltconfig.in: Eliminate uses of the NONE magic variable value. Use an empty variable instead. * ltconfig.in (with_gcc, with_gnu_ld): Do the tests for the C compiler and linker if the variables are unset, or if they are not GNU C and ld. (RANLIB): Eliminate redundant `if' statement. * configure.in: Use AM_PROG_LD. * libtool.m4 (AM_PROG_LD_GNU): New macro to determine if LD is GNU ld. (AM_PROG_LD): Rename AM_PATH_PROG_LD to AM_PROG_LD. Parameterize so that the user can specify `--with-gnu-ld' or `--without-gnu-ld' to indicate his preference. (AM_PROG_LIBTOOL): Use it. 1997-06-30 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltconfig.in: Append /sbin to the path before running ldconfig on Linux. This helps superusers who haven't set their PATH correctly. Suggested by Kenneth Albanowski. * tests/if.test: New test to make sure that we haven't forgotten to follow an `if' statement with a `test' command. This should avoid the majority of hard-to-track bugs. 1997-06-29 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltmain.sh.in: Change all the `eval "$run ..."' sequences to `$run "eval ..."'. Change all `$ln_s ...' sequences to use `(cd /dir && $LN_S ...)'. This is the sequence recommended by the Autoconf manual, and should avoid any problems on older machines. Eliminate all uses of `cp -p'. Reported by Akim Demaille. (install): Use `test $# -gt 0' instead of `test -n "$1"'. * ltconfig.in (LN_S): Add test to see if `ln -s' works. * libtool.m4: Increment serial number, and require AC_PROG_LN_S. 1997-06-26 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltmain.sh.in (link): Add missing `test' statement. Reported by Akim Demaille. 1997-06-24 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * libtool.m4 (LD): Consistently use ac_cv_path_ld instead of am_cv_path_ld. From Tim Pierce. 1997-06-20 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltmain.sh.in: Redo two robustness fixes. Alexandre had the correct approach, but I botched them. * ltconfig.in (dynamic_linker): Disable shared libraries on MkLinux unless GNU libc is in use. Reported by Akim Demaille. 1997-06-19 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltmain.sh.in (install): Add a missing `test' command. Reported by Joel Weber. Miscellaneous fixes to improve robustness. From Alexandre Oliva. * tests/demo-conf.test (CONFIG_SITE): Set to /dev/null, so that the config.site file doesn't mess up our prefix. Reported by Joel Weber. * tests/demo-inst.test: Always run both hell.static and hell. * tests/demo-conf.test: Always remove the local config.cache, but run `make distclean' only if the Makefile exists. Otherwise, the demo directory is not cleaned up if a user uses their own config.cache. Reported by Joel Weber. 1997-06-14 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltmain.sh.in (link): Create invalid libtool objects when partial linking if we don't have PIC. From Jeff Dairiki. (install): Fix bug if libtool object is installed to a file name without directory components. From Jeff Dairiki. 1997-06-13 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * Makefile.am (demo/configure): Fix up rules to run autoconf. (aclocal.m4): Now we depend on our own libtool.m4. * configure.in (AM_PATH_PROG_LD): Use it. * libtool.m4 (AM_PATH_PROG_LD): New macro to find the linker used by the C compiler. (AM_PROG_LIBTOOL): Use it. * ltmain.sh.in (install, uninstall): Support installing and uninstalling `.lo' files. From Jeff Dairiki. 1997-06-11 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * Makefile.am (ltconfig, ltmain.sh): Only move if $(srcdir) is not the current directory. Don't regenerate every time the package is reconfigured. Reported by Tom Tromey. (MAINTAINERCLEANFILES): Added ltconfig, ltmain.sh, so that $(srcdir) is not messed with during a regular clean. 1997-06-10 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * Makefile.am (ltconfig, ltmain.sh): Be sure to move these files into $(srcdir) once they are created. * ltmain.sh.in (link): Disable building static libraries. People should use their favourite AR and RANLIB commands. Disable building old-style objects if `--disable-static' is given. Suggested by Tom Lees and Stephan Kulow. 1997-06-08 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltconfig.in (host_cpu, host_vendor, host_os): Patch up definitions, to allow for the fact that the host_os may contain hyphens (as in linux-gnu). From Scott Goehring. * ltmain.sh.in (link): Move the `dlname' setting closer to the top of the file. Suggested by David Mosberger-Tang. Symlink the libtool archive into the `.libs' directory so that it can be found by programs that want to find a library's dlname by searching LD_LIBRARY_PATH. Reported by David Mosberger-Tang. 1997-06-06 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * Tell people to report bugs to the new libtool mailing list, <bug-libtool@gnu.ai.mit.edu>. 1997-06-05 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltconfig.in (allow_undefined_flag): New variable that implements `-allow-undefined'. (archive_cmds): Enable C++ constructors for FreeBSD 2.2. From David Nugent. * ltmain.sh.in (link): Accept new `-allow-undefined' flag when building libtool libraries. This tells libtool to allow unresolved symbols to exist in shared libraries. Basically, this turns off shared libraries on AIX. Suggested by Ian Lance Taylor. 1997-05-26 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * libtool.m4 (LD): On at least IRIX, many different flags need to be propagated to the linker if they are part of the compiler command line. Reported by Anthony Green. 1997-05-10 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltconfig.in: Trivial port to FreeBSD 3. From David Nugent. 1997-04-25 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltmain.sh.in (link): Remove all traces of `-whole-archive', `-no-whole-archive', and libtool convenience libraries. They were more trouble than they're worth. If these are ever reimplemented, they need more careful attention to make portable. * libtool.m4, ltconfig.in: Added a `--disable-static' flag to turn off static library creation. From Tom Lees (who finally convinced me that it was the Right Thing to do). 1997-04-22 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltmain.sh.in (hardcode_runpath_var, runpath_var): Use them, if the linker has no -rpath flag. Quote the values we use to set runpath_var and shlibpath_var. (link): Use libobjlibs for libtool convenience libraries. * ltconfig.in (hardcode_runpath_var, runpath_var): Add new variables to describe linkers that honour `LD_RUN_PATH'. (host_cpu, host_os): Use these more specific variables, rather than the full canonical host system name. * ltmain.sh.in (dlname): Distinguish between missing `-export-dynamic' and when the library is only statically linked. 1997-04-21 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltconfig.in: Trivial port to OpenBSD by making it an alias for NetBSD. From Tim Pierce. 1997-04-16 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltconfig.in: Temporary measures to check for a broken collect2 program. Right now, we just see if we're using GCC on AIX 3. * tests/hardcode.test: AIX also has arbitrary limits on the line length of input to fgrep(1), so we need to translate NUL characters to newlines in order to properly detect embedded `.libs'. From Bruno Haible. Also redirect stderr to /dev/null, so that AIX users don't get worried by `fgrep: Maximum line length of 2048 exceeded.'. 1997-04-13 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltmain.sh.in (mode): Use `egrep -e' when inferring the operation mode. 1997-04-12 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltconfig.in (linker): Some GNU ld's don't accept `--version', but do accept `-v'. From Jukka Honkela. (ld_shlibs): AIX lossage may be settling down. AIX 3.2.5 ld does *not* hardcode direct libraries, but AIX 4.1.[45] ld does. 1997-04-07 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltconfig.in (hardcode_action): Fix silly logic error. From Bruno Haible. 1997-04-05 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltmain.sh.in (install): Relink if hardcode_action is `relink', rather than using complex conditionals based on the other hardcode variables. * ltconfig.in (hardcode_action): Set to `relink', not `immediate', if we can only hardcode existing directories. Rearrange conditionals to make the intent clearer, otherwise this can be one hellish piece of code for the already-dizzy libtool maintainer. 1997-04-02 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * replfunc.m4: Delete from the distribution. Documentation now describes how to set LTALLOCA and LTLIBOBJS in your own configure.in. * ltmain.sh.in (link): Make sure a libtool library only counts as a shared library if its library_names are non-null. Use timestamps for .lo's when PIC is turned off, rather than symlinking to the real object. This helps invalid mixtures of PIC and non-PIC to fail. 1997-04-01 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * Makefile.am (EXTRA_DIST): Distribute libtool.prj. * Shameless plug: Changed source code management system from CVS to PRCS. * libtool.scm: Initial Guile implementation of libtool. * ltmain.sh.in: An unexpected inconsistency in my whole approach to shared libraries has proven that libtool needs to be completely rewritten if I'm going to give full shared library support for platforms that don't use the GNU C library version 2 (which to my knowledge currently only works on GNU Hurd and Linux/GNU systems). Porting the GNU C library should not be difficult, though. Platforms that don't have the dlopen(3) family of functions will need to install GNU DLD version 4 in order to build any kind of libraries at all. Unfortunately, DLD 4 won't be released for a while, because I maintain it, and I'm too busy working on libtool. I'll keep the old ltconfig/ltmain.sh implementation around for as long as I can, and continue applying bug fixes, so that I'll have a reasonable starting point for this new libtool implementation. It looks like this implementation will be even more complex than the original (pre-0.7) libtool. Initial estimates show that it may be up to 3 times slower, and 5 times larger than libtool-0.9. I'll probably have to rewrite it in Guile to get reasonable performance, which will severely limit its portability for a while. That will also introduce a bootstrapping issue, since the next release of Guile will use libtool to build shared libraries. So, if users want to have shared Guile libraries, they will have to configure Guile with `--disable-shared', compile it, install it, then reconfigure Guile with `--enable-shared' and repeat. I was hoping to get libtool 1.0 out the door by early April, but now it looks like it will take at least another year before it'll be usable by the public at large. April fools. libtool.scm doesn't exist yet, either. * ltconfig.in (verify_host): Remove redundant `Transform *-*-linux* to *-*-linux-gnu*'. From Bruno Haible. * tests/hardcode.test: AIX 3 doesn't have strings(1) so we need to do a funny tr and pipe the output to fgrep. From Bruno Haible. 1997-03-31 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * Makefile.am: Use the new AUTOMAKE and ACLOCAL variables. * ltmain.sh.in (link): Only fail if a convenience library doesn't exist, and the user specified -whole-archive. Fix shell quoting that was breaking @OUTPUT@ substitution. 1997-03-28 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltmain.sh.in (link): Use the hardcode_libdir_separator. Convenience libraries are libtool objects if we're not building libtool libs. * ltconfig.in (hardcode_libdir_separator): Added in case the linker only honours the last of the -rpath flags (but it can contain multiple colon-separated directories), such as on OSF/1. Reported by Carl D. Roth. * ltmain.sh.in (link): Set the dlname if -export-dynamic is given. (install, uninstall): Handle the dlname file separately. * ltconfig.in (export_dynamic_flag): Added to allow programs to use reflexive dlopens. * ltmain.sh.in: Include the mode name in any help messages. (dlname): New mode to give the name to be used with dlopen(3). * ltconfig.in (AR): Allow AR to be set by the user, and export it to ltmain.sh. * ltmain.sh.in: Remove broken profiled library support. Added `-whole-archive' and `-no-whole-archive' to manipulate convenience libraries. 1997-03-27 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltmain.sh.in (link): Allow the creation of static convenience libraries made of libtool objects. Suggested by David Mosberger-Tang. 1997-03-25 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltconfig.in: On AIX, libtool also needs to look for `B' symbols in nm output. These are global variable definitions. * ltmain.sh.in: Linking with -static should link against the linklib if old_library is empty (like it is on AIX). * ltconfig.in: Change the order of OS detection, so that linux-gnu* is detected before gnu*. * Makefile.am (libtool): Use the correct CC, RANLIB, LD, when generating libtool. From Carl D. Roth. * configure.in: Find out the user-supplied CC, LD, RANLIB. From Carl D. Roth. 1997-03-24 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltmain.sh.in: Linking with -static should link against the old library, not linklib. * README-automake: Updated to point to Automake 1.1m. 1997-03-15 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * demo/main.c: Use it. * demo/foo.h: Declare it. * demo/foo.c: Added definition of `nothing' so that we have an global variable definition, as well as functions. 1997-03-12 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltconfig.in: Make sure either enable_shared or enable_static is configured. Reported by Tom Tromey. * ltmain.sh.in: Bomb out if no library types are configured. 1997-02-22 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltconfig.in, ltmain.sh.in (hardcode_libdir_flag_spec): Renamed from `hardcode_libdir_flag'. (library_names_spec): Renamed from `lib_names'. * ltconfig.in, ltmain.sh.in (hardcode_action): Change value from `rpath' to `immediate'. * replfunc.m4: Add AM_FUNC_ALLOCA, AM_FUNC_MEMCMP, and AM_STRUCT_ST_BLOCKS. 1997-02-18 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltconfig.in: Transform *-*-linux* to *-*-linux-gnu* to support old-style config.guess scripts. 1997-02-17 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltmain.sh.in: Create objdir *before* linking a program into it. 1997-02-12 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltconfig.in: Any ld --version that returns GNU is probably a GNU ld. From Marcus Daniels. * libtool.m4: Added AM_REPLACE_FUNCS. 1997-02-11 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltconfig.in: Trivial port to *-*-osf4. From Bruno Haible. 1997-02-10 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltconfig.in: AIX 3 and 4 ld only hardcodes LIBPATH if -L is not specified. This behaviour is the same with both xlc and gcc. 1997-02-07 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * doc/platforms.texi: Yaay! We found a workaround for HP-UX /bin/sh buffer overflows. From Eric Backus. 1997-02-03 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * Release 0.9. * PLATFORMS, doc/platforms.texi, Makefile.am, doc/Makefile.am: Move PLATFORMS to doc/platforms.texi. * ltmain.sh.in (link): Use hardcode_libdir_flag to get a library directory into the resulting binary. Use hardcode_action, and make many simplifying changes to have compilation and finalization be consistent with each other. * ltconfig.in: Not so amazing! It's AIX cc that hardcodes direct libraries... gcc doesn't, though. (link_rpath_flag): Change link_rpath_flag to be hardcode_libdir_flag. (hardcode_action): New variable to simplify ltmain.sh. * tests/Makefile.am (TESTS): Do the full make sequence with --disable-shared, then without. * tests/demo-sttc.test: Configure the demo directory with --disable-shared. 1997-01-29 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltmain.sh.in: Change to take advantage of linkers that don't hardcode direct libraries. * ltconfig.in: Amazing! AIX 3 linker doesn't hardcode direct libraries, which makes it less buggy than AIX 4. Reported by Mark Kettenis. * demo/configure.in: Check for the math library. * demo/foo.c (foo): Change to use the `cos' function, so that we need to link against another library. * tests/hardcode.test: Rewrite to use fgrep on output from ``strings -a'' if using fgrep directly on the binary files fails. From Mark Kettenis. 1997-01-28 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltmain.sh.in (link): Export the PATH variable in order to find the program, rather than giving a full path. This helps give the program a less confusing value for argv[0]. * tests/hardcode.test: Make sure that ../demo/libhello.la really is a shared library before running hardcoding tests. 1997-01-26 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * Release 0.8. 1997-01-24 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * Makefile.am (demo_distfiles): Add demo/acinclude.m4 to the distribution. 1997-01-22 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * libtool.m4: For IRIX 6, ld needs -n32 if cc uses it. Reported by Bruno Haible. * ltconfig.in: IRIX ld does not hardcode direct libraries. Reported by Bruno Haible. 1997-01-18 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltconfig.in, ltmain.sh.in (hardcode_shlibpath_var): Allow new value, `unsupported', since most linkers do not allow you to use shlibpath_var for initial linking. * ltconfig.in: Lots of bug fixes from Bruno Haible. Set wl on OSF/1, fix definitions of hardcode_* variables. (archive_cmds): Fix not to use +h on HP-UX 9.x. Reported by Bruno Haible. * tests/demo-conf.test: Use the CONFIG_SHELL environment variable when running configure in the demo directory. From Bruno Haible. * tests/Makefile.am (clean-local): Make distclean in the demo directory, so that ``make clean; env CC=cc make check'' works as one would expect. * tests/demo-make.test: Fix typo (use $make instead of make). Reported by Akim Demaille. 1997-01-17 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * libtoolize.in: Handle explicit AC_CONFIG_AUX_DIR settings. Suggested by Akim Demaille. * libtool.m4: Change ltconfig line to use $CONFIG_SHELL when it is specified. Reported by Bruno Haible. 1997-01-16 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * demo/Makefile.am (hc-direct): Do better searching for the proper name to do a direct link. (hc-libpath): Make allowances if shlibpath_var cannot be used to find libraries at link time, such as on AIX. * Makefile.am (demo_distfiles): Remove ansi2knr.1 and ansi2knr.c. * demo/foo.c, demo/hello.c, demo/main.c: Change ANSI prototypes to KNR form, for better portability, and less ansi2knr hair. * demo/configure.in: Remove AM_FUNC_PROTOTYPES. * demo/Makefile.am: Remove ansi2knr from the AUTOMAKE_OPTIONS. * demo/ansi2knr.1, demo/ansi2knr.c: Removed these files. * ltmain.sh.in: Use 1>&2 consistently to direct errors and warnings to stderr. (compile): Fix missing single quote. * ltconfig.in (hardcode_direct): On Solaris at least, using DIR/libNAME.so does not hardcode DIR, so introduce a new hardcode variable to reflect that. * ltmain.sh.in (link): If linking with $link_static_flag fails, then retry without it, but still use the .a versions of uninstalled libtool archives. * tests/tlibtool: Rewrote to grab all the settings from the generated libtool script. * tests/hardcode.test: Make allowances if shlibpath_var cannot be used to find libraries at link time, such as on AIX. 1997-01-15 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltmain.sh.in (link): Eval $link_static_flag. Reported by Bruno Haible. * PLATFORMS: Add to distribution. Suggested by Bruno Haible. 1997-01-14 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * tests/demo-conf.test, tests/demo-inst.test, tests/demo-unst.test, tests/hardcode.test: Use $make instead of make. * tests/defs (make): Add definition of $make that uses the $MAKE environment variable, if set. Suggested by Bruno Haible. * tests/demo-unst.test (leftovers): Change the find command to ignore files beginning with a dot, as egrep -v doesn't seem to do the trick. Reported by Bruno Haible. 1997-01-13 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltconfig.in: Add support for SCO OpenServer 5.x. From Christopher Olsen. (can_build_shared): Initialize at the top of the file, so that shared libraries aren't built on platforms that don't support them. * tests/hardcode.test: Added a test to make sure that libtool's idea of hardcoding system linkers is correct. 1997-01-11 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltmain.sh.in, ltconfig.in, libtoolize.in, doc/libtool.texi: Update the copyright completion years. 1997-01-08 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltconfig.in: Port to IRIX 5.3, 6.2. 1997-01-06 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltconfig.in: HP-UX 9 support is the same as HP-UX 10, so the port is trivial. * libtoolize.in: Add --dry-run option, -n for short. 1997-01-03 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltmain.sh.in (link): On at least SunOS, /bin/sh doesn't understand "export something=val". From Bruno Haible. * tests/Makefile.am (distclean-local): Remove all files that the tests may have created. Reported by Bruno Haible. * For all tests, discover srcdir when running from the command line. * tests/demo-unst.test: Don't fail if make uninstall doesn't delete files beginning with a dot, since spurious .nfsXXX files may be present when running NFS. Reported by Bruno Haible. 1997-01-02 Gordon Matzigkeit <gord@gnu.ai.mit.edu> * ltmain.sh.in (compile): Recognize valid source file suffixes for Fortran and C++. * tests/suffix.test: New test to guarantee that libtool compile recognizes valid source file suffices.
