output of NM too
(global_symbol_to_cdecl): new variable; convert the output of
global_symbol_pipe to valid C declarations; on HP/UX, convert
text symbols to function declarations
* libtool.m4: similar modifications
* doc/libtool.texi: document new variable
* ltmain.in: use global_symbol_to_cdecl to generate lt_dlpreopened
symbols; avoid extracting symbol lists from dlpreopened files
twice; do not filter symbols from dlpreopened libraries
* TODO: fixed HP/UX dlpreopening problem
(AC_LIBTOOL_SETUP): if lt_dlopen=yes, add --enable-dlopen to
libtool_flags; drop --enable-dlopen-self
* ltconfig.in: perform all the dirty work of testing for dlopening
support, because we need platform-dependent equivalents for
-export-dynamic, for self dlopening, and -static, for static self
dlopening
(dlopen_self_static): new configuration variable that is set to
yes only if static programs can dlopen themselves
* ltmain.in (-static, -all-static): dlopen_self=dlopen_self_static
dlfcn.h and LTDL_LAZY exist; use LTDL_GLOBAL and LTDL_LAZY_OR_NOW.
This test is likely to fail if self-dlopening does not work,
especially because we do not link the program with
-export-dynamic. Let's just hope that platforms whose symbol
names start with underscores will also accept underscores for
dlopen. We should probably use libtool to compile and link this
test, so that we can use -export-dynamic.
avoid introducing multiple --enable options when re-running
config.status
* libltdl/configure.in: if enable_ltdl_* is not set, assume no
* configure.in: if enable_ltdl_install is not set, enable it
configure-work that AC_PROG_LIBTOOL used to do; add
--cache-file=$cache_file to libtool_flags
(AC_PROG_LIBTOOL): call AC_LIBTOOL_SETUP, save the cache, run
ltconfig and reload the cache
* configure.in: run AC_LIBTOOL_SETUP, then set LIBTOOL_FLAGS to
libtool_flags
* ltconfig.in: support --cache-file switch. If it is used, load
the cache in the beginning and save it just before terminating
always configure libltdl, add libltdl/acinclude.m4 to
ACINCLUDE_M4_LIST, disable installation of libltdl if necessary
* libltdl/Makefile.am: set version info for libltdl.la
* libltdl/configure.in: don't check whether
enable_ltdl_convenience/install was set so that libltdl
can be used as independent package (libltdl.tar.gz) without
the need to use --enable-ltdl*
* libltdl/ltdl.c: minor cleanups, allocate the line cache
dynamically (lt_dlopen)
renamed convenience libltdl, dropped toinst hack for installable
* libltdl/Makefile.am: ditto
* libltdl/configure.in: ditto; abort if none of the macros is used
new macros
* NEWS: ditto
* libltdl/configure.in: if none of the new macros or configure
arguments are used, warn and build convenience library only
* libltdl/Makefile.am: conditionally build convenience libltdl.la
* mdemo/configure.in: use AC_LIBLTDL_CONVENIENCE
* mdemo/Makefile.am: refer to @LIBLTDL@
then translate them to the export_symbols format. Now it works,
but it appears to be needlessly extracting the symbol list from
dlpreopened libraries twice
libltdl must not be renamed; if there's a problem with the install
option, let's fix it, not just work around it by breaking code of
users of the convenience library
