## Process this file with autoconf to create configure. -*- autoconf -*-
Reorganise the libtool tree to create a bootstrapped libltdl for installation to the libtoolize master tree, so that libltdl is useable even in the extreme case of when automake and autoconf are not installed on the developers machine. Part of this change requires some duplication of rules between Makefile.am (which builds libltdl for this distribution) and libltdl/Makefile.am (which is used by projects that libltoolize --ltdl --copy), so libtool now really does use a single toplevel Makefile.am, and we generate libltdl/Makefile.am from that: * m4, config: Moved from here... * libltdl/m4, libltdl/config: ...to here, to reduce the amount of kludging needed in bootstrap for autoreconf to run. * tests/cdemo/Makefile.am, tests/demo/Makefile.am, tests/depdemo/Makefile.am, tests/f77demo/Makefile.am, tests/fcdemo/Makefile.am, tests/mdemo/Makefile.am, tests/mdemo2/Makefile.am, tests/pdemo/Makefile.am, tests/tagdemo/Makefile.am (ACLOCAL_AMFLAGS): Adjust to compensate. * tests/cdemo/configure.ac, tests/demo/configure.ac, tests/depdemo/configure.ac, tests/f77demo/configure.ac, tests/fcdemo/configure.ac, tests/mdemo/configure.ac, tests/mdemo2/configure.ac, tests/pdemo/configure.ac, tests/tagdemo/configure.ac (AC_CONFIG_AUX_DIR): Ditto. * libltdl/m4/ltdl.m4: Increment serial number. (LTDL_INIT): Accept an optional directory argument to prefix each of the LD_DLLOADERS locations. Default to empty for backwards compatibility. * Makefile.maint: Adjust to compensate. * configure.ac (AC_CONFIG_AUX_DIR, AC_CONFIG_MACRO_DIR): Adjust. (AC_CONFIG_LIBOBJ_DIR): Set here so that we can build LTLIBOBJS from in a subdirectory from the amalgamated Makefile.am. (AM_PROG_CC_C_O, AM_INIT_AUTOMAKE): Use subdir-objects. (AC_CONFIG_FILES): Remove libltdl/Makefile.am. * libltdl/Makefile.am: Removed from repository, and merged into Makefile.am as we now generate it... * Makefile.am (libltdl/Makefile.am): ...from here, by extracting the merged rules, and tweaking paths to accomodate the difference in directory from Makefile.am to libltdl/Makefile.am. (nobase_dist_pkgdata_DATA): Automake generated installation rules change timestamps of installed files, so renamed this... (configauxfiles): ...to this... (libtoolize): ...substitute it... (install-data-local): ...install manually, preserving timestamps... (install-data-hook): ...and set execute bit as appropriate. (uninstall-hook): Not forgetting to remove them at uninstall. (libltdl/Makefile.in): New rule. Called from... * bootstrap: ...here to avoid relying on config.status at bootstrap time. (auxdir, m4dir): Extract from configure.ac for ease of future maintenance. Adjust all references. (reconfdirs): Call autoreconf for libltdl too -- even though we don't use it for the build, libltdl/configure and friends are installed with `libtoolize --ltdl --copy'. * libtoolize.m4sh: Add files from the installed config master tree to libtoolize --ltdl project subdirectory. Diagnose duplicated files when --ltdl is used in an autotooled project. It's perfectly fine to run `libtoolize --ltdl --copy' in a tree that has no configure.ac or configure.in; we want libltdl to be useful even to projects that don't use autotools themselves. (libtoolize_flags): Removed. Changed all callers. (func_massage_pkgconfig_files): New function. * tests/standalone.at: New tests for using libltdl without supporting configury in the parent project. * tests/testsuite.at: Run them! * NEWS: Updated.

Sweeping changes to the user interface to libtool from `configure.ac' to be more like AC_INIT and accept a space delimited list of options. Instead of calling `AC_LIBTOOL_DLOPEN; AC_PROG_LIBTOOL', we now recommend `LT_INIT([dlopen])': * m4/libtool.m4 (AC_PROG_LIBTOOL, _AC_PROG_LIBTOOL) (AC_LIBTOOL_SETUP): Removed. Added AU_DEFUNs. (LT_INIT): Replace with an Autoconf like interface which accepts a version number as a minimum required libtool release at configure time. * m4/ltoptions.m4: New file inspired by automake/m4/amoptions.m4, which additionally flags an error if the configuring libtool macros are not new enough according to LT_INIT. (LT_OPTION_DEFINE): New macro to declare option handlers. (dlopen, win32-dll, shared, disable-shared, static) (disable-static, fast-install, disable-fast-install, pic-only) (no-pic): Newly LT_OPTION_DEFINEd option handlers that use... (_LT_ENABLE_SHARED, _LT_ENABLE_STATIC, _LT_ENABLE_FAST_INSTALL) (_LT_WITH_PIC, _LT_WIN32_DLL): New macros to handle LT_LIBTOOL_INIT options... * m4/libtool.m4 (AC_ENABLE_SHARED, AC_ENABLE_STATIC) (AC_ENABLE_FAST_INSTALL, AC_LIBTOOL_DLOPEN, AC_LIBTOOL_WIN32_DLL): ...to replace these user interface macros, now defined as AU_DEFUNs. (AC_DISABLE_SHARED, AC_DISABLE_STATIC, AC_DISABLE_FAST_INSTALL): Removed. No longer required with LT_INIT_LIBTOOL interface. Added AU_DEFUNs. (AM_ENABLE_SHARED, AM_DISABLE_SHARED, AM_ENABLE_STATIC) (AM_DISABLE_STATIC): Changed AU_DEFUNs to match new interface. (_LT_SETUP): Internal to LT_INIT, replaces AC_LIBTOOL_SETUP. * m4/lt~obsolete.m4 (AC_LIBTOOL_SETUP, _AC_PROG_LIBTOOL) (_LT_PROG_LTMAIN): More AC_DEFUNs that have been retracted. * configure.ac: Use new interface. * doc/libtool.texi: Document new interface. * NEWS: Updated.
