only if --enable-ltdl-install
(CONF_SUBDIRS): list directories that are configured on demand,
but that must be included in the distribution
(ACINCLUDE_M4_LIST, DIST_MAKEFILE_LIST): generated from CONF_SUBDIRS
* Makefile.am (AUTOMAKE_OPTIONS): added version 1.3e and
readme-alpha, to handle README-alpha automatically
(EXTRA_DIST): removed README-alpha
(BUILD_SUBDIRS): subdirectories that are always built
(SUBDIRS): BUILD_SUBDIRS plus BUILD_LTDL
(DIST_SUBDIRS): BUILD_SUBDIRS plus CONF_SUBDIRS, from configure
(all-local, check-local): depend on $(ACINCLUDE_M4_LIST), from
configure, and libtool, so that it is built before subdirs
(configure-subdirs): new target
(configure-subdirs, distdir): depend on $(DIST_MAKEFILE_LIST),
from configure
(@DIST_MAKEFILE_LIST@): create subdir if needed, then run
configure.
On-demand configuration of subdirs at distribution time was
suggested by Gary V. Vaughan <gvaughan@oranda.demon.co.uk>
* ltmain.in, doc/libtool.texi: documented that -rpath is the same
as -R for programs
* ltmain.in: softened the instructions for linking with installed
libraries, and noted that libtool can be used to link with them;
documented that -rpath is not required for convenience libraries
the files extract from the convenience library. Some systems,
such as FreeBSD2, will add a SYMDEF file, that is not an object
file, and therefore should not be fed to the linker
depdemo commented out, so that `dist' works before `check'
(BUILD_LTDL): will contain libltdl if --enable-ltdl-install
* Makefile.am (DIST_SUBDIRS): expand SUBDIRS and add depdemo,
commented out
(SUBDIRS): add $(BUILT_LTDL)
* libltdl/Makefile.am (EXTRA_LTLIBRARIES): add libtest.la, the
same as libltdl but always a convenience library. Not built by
default. Both libraries now depend on the libtool script, that
depends on ../libtool and is rebuilt when needed
* mdemo/Makefile.am (mdemo, mdemo.debug): depend on and link with
../libltdl/libtest.la, that is rebuilt if needed
(mdemo_LDADD): removed $(LIBADD_M), to avoid silent failures
(foo1.la): renamed from libfoo1.la; test removing the lib prefix
* mdemo/foo1.c: renamed libfoo1_LTX symbols to foo1_LTX
* mdemo/main.c: don't include string.h nor math.h, nor refer to
sin nor cos
* tests/mdemo-exec.test: renamed libfoo1.la to foo1.la
* tests/mdemo-inst.test: ditto
and don't redefine it if already defined; default to 1024, as on
most systems
(LT_SYMBOL_LENGTH): renamed from MAX_SYMBOL_LENGTH
(LT_SYMBOL_OVERHEAD): new macro, that accounts for the size of
the _LTX_ separator and the initial underscore
(lt_dlsym): sym now points to a stack buffer (lsym) if possible,
or is dynamically allocated. If allocation fails, a
buffer_overflow_error is returned.
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
ltdll.c into ltmain.in, to avoid its duplication, and added a sed
script to extract it. Also, create def and base files in $objdir,
and don't remove them after the compilation.
(cygwin, library_names_spec): Create static part of the dll with
suffix -dll.a, to avoid conflicts with actual static libraries.
* ltmain.in: Added ltdll.c, as commented out text
