To safely use a non-literal fist argument to 'test', you must always prepend a literal non-'-' character, but often the second operand is a constant that doesn't begin with a '-' already, so always use 'test a = "$b"' instead of the noisy 'test "X$b" = Xa'. * cf.mk (sc_prohibit_test_const_follws_var): New syntax-check rule to ensure we don't reintroduce noisy test operands. bootstrap, build-aux/extract-trace, build-aux/general.m4sh, build-aux/ltmain.m4sh, configure.ac, doc/libtool.texi, libtoolize.m4sh, m4/argz.m4, m4/libtool.m4, m4/ltdl.m4, tests/bindir.at, tests/defs.m4sh, tests/demo-relink.test, tests/demo/configure.ac, tests/depdemo-relink.test, tests/destdir.at, tests/duplicate_conv.at, tests/fail.at, tests/getopt-m4sh.at, tests/help.at, tests/libtoolize.at, tests/link-2.test, tests/link-order2.at, tests/lt_dlopenext.at, tests/mdemo/configure.ac, tests/mdemo2/configure.ac, tests/need_lib_prefix.at, tests/nocase.at, tests/pdemo/configure.ac, tests/pic_flag.at, tests/search-path.at, tests/shlibpath.at, tests/static.at, tests/sysroot.at, tests/tagtrace.test, tests/testsuite.at, tests/with-pic.at: Swap operands to avoid useless noise.

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.
