* THANKS: Added Rob Collins and Chuck Wilson for their cygwin work. From Robert Collins <robert.collins@itdomain.com.au>: * configure.ac (AC_EXEEXT): Needed for DOSish systems. * libtool.m4 (shlibpath_overrides_runpath) [cygwin]: Set to yes when compiling with gcc. (lt_prog_compiler_pic) [cygwin]: No longer needs the -DDLL_EXPORT hack, so we just say the pic is the default. (AC_LIBTOOL_PROG_LD_SHLIBS) [cygwin]: Extract symbols from a library normally. [cygwin]: Declare C++ compiler characterisics for g++, taking into account the new auto-import support in cygwin ld. * ltmain.in (specialdeplibs) [cygwin]: Be careful about eliminating duplicate -lgcc's from the link line. [cygwin]: Be smarter about .exe suffixes. * demo/configure.ac (AC_EXEEXT, AC_LIBTOOL_WIN32_DLL): Support DOSish systems properly. * depdemo/configure.ac (AC_EXEEXT, AC_LIBTOOL_WIN32_DLL): Ditto. * demo/Makefile.am (deplibs-check): Allow for .exe suffix. Use hell_static instead of hell.static for multi-`.' inhibited OSes. * tests/demo-exec.test: Ditto. * tests/demo-inst.test: Ditto. * demo/foo.h [cygwin]: Sanitize cygwin dll support. * demo/foo.c (_LIBFOO_COMPILATION_): No longer required. * demo/hello.c (_LIBFOO_COMPILATION_): Ditto. * depdemo/Makefile.am (bin_PROGRAMS): Use depdemo_static instead of depdemo.static for multi-`.' inhibited OSes. * tests/depdemo-exec.test: Ditto. * tests/depdemo-inst.test: Ditto. * mdemo/Makefile.am (bin_PROGRAMS): Ditto for mdemo.static. * tests/dryrun.test: Ditto. * tests/mdemo-exec.test: Ditto. * tests/mdemo-inst.test: Ditto. * tests/build-relink.test: Be careful about possible .exe suffixes. * tests/noinst-link.test: Allow for .exe suffix. |

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.
