to be before AC_LIBTOOL_PROG_LD_HARDCODE_LIBPATH, becuase the
value of shlibpath_overrides_runpath is used in the HARDCODE
test and is set in the DYNAMIC_LINKER test.
* ltmain.in(darwin): We never need to relink on darwin.
* configure.ac: Fix misapplied patch in last commit
* libtool.m4 (darwin): Check compiler is apple gcc, add -single_module
support so that dyloading c++ shared libraries will work.
* libtool.m4 (_LT_AC_TAGCONFIG): Add test -n to the tests so that
it will work outside of libtool.
* doc/PLATFORMS: Add darwin
* f77demo/configure.ac: Add config.h which was misapplied previously.
Changes for darwin building. Warn if linking against libs linked
with -module. Use module_cmds if available and building a module,
move convenience double lib check,
* libltdl/ltdl.c: ltdl support for darwin (first blush)
* libltdl/README: note that darwin is supported
* ltdl.m4: Changes for darwin, and for new shrext
* libtool.m4: Changed the way darwin builds stuff (make check passes)
added module_cmds, module_expsym_cmds and hardcode_automatic and put
them in the libtool script. check for zsh's removal of escapes. Allow
libraries to be stripped on darwin.
* TODO: Remove the todo about zsh's removal of excapes. note that zsh
echo works perfectly well, eval is screwed up. Seems to be fixed in
latest zsh.
* THANKS: added self :)
* f77demo/configure.ac: Use config.h or it doesn't work.
Prefix -soname, -set_version and their arguments with ${wl}. Add
-melf* linker scripts to LD, and use them to determine libsuff,
shlibsuff and libmagic.
the value of the shrext (aka shared_ext) variable and delete it
from the library_names_spec and soname_spec definitions. That
way the user can omit the shared library suffix by setting it
to the empty string.
(AC_LIBTOOL_LANG_CXX_CONFIG): Strengthen renaming commands for
the KCC compiler.
* doc/libtool.texi (Link mode): Update the manual.
a patch by Ross Alexander <ross.alexander@uk.neceur.com>.
Credit to Ross! Use +b to hardcode library runtime path.
Add new variable, $hardcode_libdir_flag_spec_ld, that
is equivalent to $hardcode_libdir_flag_spec but is used
when ld is used for linking. This works around having to
set wl=''.
"-shrext" option so that is works properly under Darwin.
Modify the processing of 'gcc -print-search-dirs' under
Darwin to make it behave like GNU gcc does.
(AC_LIBTOOL_CONFIG): Single quote $shrext.
* ltimain.in: Expand shared_ext just before it is used
so that it can be conditional on the value of $module.
* ltmain.in: New link option -shrext.
* libtool.m4 (AC_LIBTOOL_CONFIG): New libtool variable shrext.
(AC_LIBTOOL_SYS_DYNAMIC_LINKER): Replace all hard coded shared
library file name extensions in library_names_spec and
soname_spec with $shrext.
* doc/libtool.texi (Link mode): Document it.
$archive_expsym_cmds to restore support for using
.def files via the -export-symbols switch.
(AC_LIBTOOL_PROG_LD_SHLIBS([TAGNAME]): in both the [CXX]
branch and the default branch, improve $export_symbols_cmds
so that DATA symbols are properly labelled. In the default
branch, duplicate the _CXX_CONFIG correction for
$archive_expsym_cmds.
AC_LIBTOOL_PROG_CC_C_O): Changed method for compilation with
custom flags to be language-independent. Thereby removed
CFLAGS/GCJFLAGS mixup bug. Imitate Autoconf-style logging.
Log entries no longer discarded by compilation failures.
(_LT_AC_LANG_C_CONFIG, _LT_AC_LANG_CXX_CONFIG,
_LT_AC_LANG_GCJ_CONFIG): Tuned settings of
lt_simple_compile_test_code and lt_simple_link_test_code
to avoid warnings that could break some option detections.
(AC_LIBTOOL_PROG_COMPILER_NO_RTTI): Removed
redundant "-c conftest.$ac_ext" in the argument to
AC_LIBTOOL_COMPILER_OPTION.
(AC_LIBTOOL_PROG_LD_SHLIBS): Replaced C-specific conftest
source code with $lt_simple_compile_test_code, to support
the "-lc" test with other languages.
versions of mingw and cygwin.
(AC_LIBTOOL_POSTDEP_PREDEP): new function.
moved the "find hidden library dependencies" code here
from AC_LIBTOOL_LANG_CXX_CONFIG. Attempted to make it
multi-tag compatible, but currently only CXX calls it.
(AC_LIBTOOL_LANG_CXX_CONFIG): set
enable_shared_with_satic_runtimes to 'no' by default
Set it to 'yes' for cygwin, mingw, pw32. Replace
"find hidden library dependencies" code with a call
to the new function AC_LIBTOOL_POSTDEP_PREDEP.
Consolidate cygwin and mingw/pw32 stanzas.
(AC_LIBTOOL_LANG_F77_CONFIG): set
enable_shared_with_static_runtimes to 'no' by default
(AC_LIBTOOL_CONFIG): add
enable_shared_with_static_runtimes to the list of variables
to write into ltmain.sh; include it in the libtool script
template as allow_libtool_libs_with_static_runtimes.
(AC_LIBTOOL_PROG_LD_SHLIBS): set
enable_shared_with_static_runtimes to 'no' by default
Set it to 'yes' for cygwin, mingw, pw32.
(AC_LIBTOOL_SYS_GLOBAL_SYMBOL_PIPE): only put cr in regexp
if the build_os is mingw, not host_os
* ltmain.in (case deplibs_check_method): for all appropriate
cases, if allow_libtool_libs_with_static_runtimes, then remove
predeps and postdeps from the list of dependencies that must
be checked for "dynamicness". For the "none" case, the
presence of compiler-generated postdeps and predeps should
not trigger "inter-library dependencies not supported" error.
(initial setup after arg processing): on cygwin/mingw, allow
compiler-generated dependent libs to be duplicated without
elimination.
(initial search loop for deplibs): if the deplib in question
is a libtool lib, then if
allow_libtool_libs_with_static_runtimes then parse the .la file.
If the .la file only has an "old_library", add the deplib
directly to the deplibs list (-lstdc++) and DON'T use the .la
file; this allows the (case deplibs_check_method) change above
to take effect.
* ltmain.in (for pass in $passes loop): remove predeps,
postdeps, and compiler_lib_search_path from dependency_libs.
staging area (e.g. 'make install DESTDIR=...')
* libtool.m4 (AC_LIBTOOL_LANG_CXX_CONFIG): restore setting
allow_undefined_flag=unsupported for cygwin and mingw.
(AC_LIBTOOL_PROG_LD_SHLIBS): ditto, for both "normal" gcc/ld
and for the (unmaintained?) MSVC case.
* doc/libtool.texi (Install mode): document new
-inst-prefix option.
echo. (AC_DEPLIBS_CHECK_METHOD): use new shell function
win32_libid on w32 platforms
* ltmain.in: add new section for shell functions. Add
win32_libid() shell function.
* f77demo/Makefile.am: add -no-undefined flag
* ltdl.c (realloc): Remove custom realloc. (#define
rpl_realloc realloc) and comment out later code for custom
realloc. You can't define your own malloc unless you know
enough about the malloc in use to be able to tell how big
the src ptr is. The disabled code incorrectly used the
*destination* ptr to decide how much to copy. This
sometimes results in out-of-bound accesses which cause
segfaults. This is a quick hack for now; we may want
something cleaner later. (tryall_dlopen_module): check to
be sure (dirname_len > 0) before testing first character
against '/'. (try_dlopen): check for feof(file) in read
loop -- otherwise infloop?
-brtl special-case code for AIX never gets triggered because
were are being too specific about how we search for -brtl.
Use case statement to avoid this. Remove extraneous
semicolon.
* ltmain.in: Recognize the IBM xlc compiler.
