`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 * m4/lt~obsolete.m4 (AC_LIBTOOL_SETUP, _AC_PROG_LIBTOOL) (_LT_PROG_LTMAIN): More AC_DEFUNs that have been retracted.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. |

This is mdemo, an example package that uses GNU libtool with an Automake-generated environment to build two simple modules and a program. It demonstrates how to build both dynamic and static libraries that can be dlopened. mdemo uses libtool's portable dlopen wrapper called "libltdl". All exported symbols are prefixed with "libname_LTX_" to avoid symbols conflicts, especially when linking statically. libltdl will automatically cut the prefix off to get the real name. Note that on Windows, for the purposes of illustrating ltdl, the libraries *are* built as dll's, but do not have the __declspec machinery to make them suitable for loading at link time. This is only for clarity inside this example, look at the example in ../demo to see how the __declspec macros should be set up.
