old-fashioned archive, use a copy of libobjs saved before
convenience libraries are appended
* libltdl/ltdl.h (_LTDLL_EXPORT, _LTDLL_IMPORT): use cygwin or
unix library import/export primitives; this may be convenient for
people willing to create DLLs
(_LTDLL_EXTERN): select _LTDLL_EXPORT or _LTDLL_IMPORT depending
on _LTDL_COMPILE_
* libltdl/ltdl.h, libltdl/ltdl.c (lt_dlpreopen): new function,
that replaces the current preloaded_symbols list with its
argument, and returns the old value, initially NULL
(dldpre_init): don't refer to dld_preloaded_symbols any more
(dldpre_open, dldpre_sym): search preloaded_symbols
(lt_dlpreopen_default): call lt_dlpreopen with
dld_preloaded_symbols, that is declared as extern; it should be
called from the main program or from some static library without
-no-undefined
(lt_dlerror): new function, that returns the error message for the
last error occurred; the error message is kept in the static
variable last_error
* libltdl/configure.in (enable-ltdl-install): moved back from
enable-install; other packages might use enable-install already,
better have fine grained control over this.
* libltdl/Makefile.am (libltdls.la): discarded
* libltdl/Makefile.am (CFLAGS): ditto
* libltdl/configure.in: check for memory.h, rindex() and
dlpreopening. Fixed NEED_USCORE caching policy.
* libltdl/ltdl.h (lt_dlsym): make the name argument const
* libltdl/ltdl.c (types): new variable: head of list of available
dlopening mechanisms
(lt_dltype_t): interface of a dlopening mechanism, with pointers
to functions for init, exit, open, close and sym
(lt_dlhandle_t): added pointer to interface type
(strdup): don't name it strdup; it can be troublesome
(strrchr): ditto; use rindex if available
(LIBTOOL_STATIC): check HAVE_DLPREOPEN instead, and move to the
end of the file, so that it becomes the header of the list
(all): renamed all interface-implementation functions, to avoid
name clashes, and created lt_dltype_t nodes for all of them
(lt_dlinit): initialize all available interfaces; remove those
that fail from the list. Return failure only if no interfaces
could be initialized.
(lt_dlexit): return number of failures
(tryall_dlopen): try to open the library with all available
interfaces
(lt_dlopen): use tryall_dlopen; increased size of fixed buffers.
We should probably make these bound-checked or dynamically
allocated for the final release! Fix bug when filename did not
contain slashes; should we check for `\\' too? Try old_library if
everything else fails.
(lt_dlclose): use the interface type for closing
(lt_dlsym): make `symbol' const, use interface type for looking up
* mdemo/Makefile.am: moved mdemo/modules/* back into mdemo
(SUBDIRS): removed
(libfoo2_la_LDFLAGS): added -static; nice test. However, since it
causes -lm to linked into hell*, it causes tests that should fail
to pass
(noinst_HEADERS): no need to install foo.h
* mdemo/configure.in: remove modules/Makefile
tests/mdemo-exec.test: updated accordingly
* mdemo/Makefile.am: ../libltdl is within $(srcdir)
* libltdl, Makefile.am: added libltdl (a system independent
dlopen wrapper library extracted from mdemo)
* ltmain.in: added -module flag for compiling and linking of
modules. If enabled it compiles always both .o (with -DLT_RENAME)
and .lo files
* mdemo: modified mdemo to work with libltdl
* tests/ltdl*: added tests for libltdl
