This patch adds support for emscripten compiler for shared compilation.
* build-aux/ltmain.in: clone link-mode handling for emscripten from
unixware7.
* m4/libtool.m4: translate emscripten specific flags for shared module
building.
This hobbyist OS has already been added to `config.sub` (and
`config.guess` respectively) some time ago, but was still lacking
upstream support for building libraries using libtool.
Since it is a relatively up-to-date system with ports of modern
software, "adding support" mostly just means adding empty cases to avoid
falling though to the most basic behavior (that guarantees compatibility
at the expense of disabling everything that might be critical).
* m4/libtool.m4: Add support for SerenityOS.
Passing --no-warnings to libtool would not suppress warning messages.
* build-aux/ltmain.in: Add 'opt_warning' check before printing out
warning messages.
* tests/libtool.at: Add simple test for '--no-warnings'.
* NEWS: Update.
If an invalid argument is passed to options '--mode' or '--reorder-cache'
after a valid command, error messages will print infinitely:
$ libtool --help --mode=MODE
libtool: error: invalid argument 'MODE' for --mode
libtool: error: invalid argument 'MODE' for --mode
libtool: error: invalid argument 'MODE' for --mode
...
* build-aux/ltmain.in: Remove 'break' in case statement to fix infinite
loop, and add shift for option '--reorder-cache' to allow more options
to be processed.
A space after '-Fe' treats a file name as an input file instead of
as the intended output file.
* m4/libtool.m4: Remove space after '-Fe'.
* NO-THANKS: Add Kirill Makurin for bug report 74175.
* NEWS: Update.
Add option to reorder the shared library cache in OpenBSD so that user
preferred directories for shared libraries can be used when linking
before directories previously listed in the shared library cache.
This allows for users in OpenBSD to easily switch between versions of
libraries with the same name during testing.
* NEWS: Update for new (OpenBSD) option.
* build-aux/ltmain.in: Add option --reorder-cache=DIRS.
* doc/libtool.texi: Update documentation for new option.
* test/bug_71489.at: Alter test for OpenBSD to utilize new option.
On OpenBSD 7.5, the shared library cache is updated with finish_cmds,
which causes the test for 'Use local version' to fail. Simply, installed
versions of shared libraries take precedence over those locally built.
To ensure local versions of shared libraries can be tested properly and
more easily, additional options have been added to libtool to skip
executing finish_cmds, like 'ldconfig -m $libdir' in OpenBSD.
* build-aux/ltmain.in: Add libtool option, '--no-finish.
* doc/libtool.texi: Document new option in libtool.
* NEWS: Update.
When generating an executable in OpenBSD, the executable fails to
generate when shlibpath_var, LD_LIBRARY_PATH, is used solely to
locate dependent libraries.
For hardcoding library paths in OpenBSD, see documentation for
hardcode_direct and hardcode_libdir_flag_spec.
* m4/libtool.m4: Update hardcode_shlibpath_var from 'no' to 'unsupported'
by removing 'with_gnu_ld=no' for OpenBSD.
The GCC/binutils tools support response files just fine, while
lld (impersonating GNU ld) only supports response files, not
linker scripts. Using a linker script as input just to pass a
list of files is overkill for cases when a response file is enough.
* build-aux/ltmain.in: Move creation of ld script.
* m4/libtool.m4: Add new variable tag for file_list_spec.
* NEWS: Update.
The following errors can be seen for the 'execute mode' test in OpenBSD:
build/libtool: test: <: missing second argument
build/libtool: test: >: missing second argument
The cwrapper in OpenBSD cannot parse these symbols as arguments in
execute mode if there are no other characters with them.
* tests/execute-mode.at: Escape '<' and '>' in OpenBSD.
Update tests to skip if required autotools are not installed for
executing AUTORECONF and to have stdout saved for checks.
* tests/bug_42313.at: Use LT_AT_AUTORECONF instead of AT_CHECK.
* tests/testsuite.at: Save stdout for LT_AT_AUTORECONF.
This test is added to ensure path comparisons pass when
installing to a destination, specifically when there is a
trailing slash in the destination.
* tests/destdir.at: Add test for trailing slash in destination.
A command like:
libtool --mode=install /usr/bin/install -c gck-roots-store-standalone.la
'/image/usr/lib/gnome-keyring/standalone/'
where the path ends with a trailing slash currently fails. This occurs in
software like gnome-keyring or pulseaudio and is because the comparision
code doesn't see the paths as equal. Strip both paths to ensure this works
reliably.
* build-aux/ltmain.in: Strip trailing slashes on install commands.
* NEWS: Update.
Avoid duplication of '(GNU @PACKAGE@) @VERSION@' in multiple
places by using '$scriptversion'.
* libtoolize.in, build-aux/ltmain.in: Change version from
'(GNU @PACKAGE@) @VERSION@' to '$scriptversion'.
As said in the Autoconf source, the AC_TRY_EVAL macro is dangerous and
undocumented, and should not be used.
In particular, the one related to nm yields binary data in the config.log
file with dash, where "echo \\1" (echo with the argument \1) produces the
control character ^A instead of the usual \1 with most shells (POSIX says
that the result is implementation-defined). See:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=910076
This patch attempts to replace this AC_TRY_EVAL occurrence by code with
similar behavior, but using $ECHO instead of echo in order to avoid the
backslash issue.

If $multilib is set to more than one word, the following error can be
seen during configuration:
test: too many arguments
* m4/libtool.m4: Wrap variable in quotes.
If `multilib` is unset (which it apparently is by default), the output
from running a `configure` script contains lines like the following:
```
checking dynamic linker characteristics... ../configure: line 26791: test: yes: unary operator expected
Win32 ld.exe
```
The additional output is not a fatal error. But it could be irritating.
Avoid the unexpected output from `test` by making sure `=` is used as a
binary operator.
* m4/libtool.m4: Prepend "x" on both sides of a comparison with `test`
and the operator `=`.
* NEWS: Update for bug fix.

The variable, LT_ARGZ_H, can be empty, which causes distclean and
maintainer-clean to error as a directory is attempted to be removed
instead of a file.
When running maintainer-clean for gnulib-tests, the .version file is
missing, which is needed by config.status, so the command will error.
* configure.ac: Update CONFIG_STATUS_DEPENDENCIES to use dotversion so
that the .version file can be generated if needed.
* libltdl/ltdl.mk: Add conditional with LTARGZH_EXISTS to append path for
LT_ARGZ_H file to BUILT_SOURCES.
* m4/ltdl.m4: Add AM_CONDITIONAL for LTARGZH_EXISTS that is set to
true if LT_ARGZ_H is non-empty.
* NO-THANKS: Add 'Michael Pratt' for bug#73672 contribution.
* NEWS: List additional bug fix.
'-single_module' detection is broken with Xcode 15, where a message to
stderr indicates the flag is deprecated, not unsupported.
* m4/libtool.m4: Check macOS versions to see if '-single_module' flag is
unnecessary.
Five tests use aclocal, but do not have a check for whether aclocal is
available to use. This causes reported tests failures in Linux From
Scratch and Darwin builds.
* tests/standalone.at: Add AT_XFAIL_IF check for aclocal for all tests.
* tests/subproject.at: Add AT_XFAIL_IF check for aclocal for last test.
* Makefile.am: Fix typo.
* doc/libtool.texi: Add missing test case descriptions and specify
option and command where missing in test case descriptions.
The file magic test fails to determine the file type of libraries when
cross-compiling with an aarch64 compiler without additional strings to
search for in an objdump.
* build-aux/ltmain.in: Append 'pe-aarch64' to file_magic in the
lt_cv_deplibs_check_method.
* m4/libtool.m4: Append 'pe-aarch64' to file format check.
