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.
