So far I have the following for creating a 'plugin' module:
AC_TRY_CPPFLAGS("-Wall", wall="-Wall", wall="")
CXXFLAGS="-g $wall"
MODULE_LDFLAGS="-export-dynamic -module -avoid-version"
For example, a module called libFS.la (Filesystem module) will produce
libFS.la and libFS.so in the installation directory. The only way that I
know to only see libFS.so in the install directory is to place a script
in the Makefile.am to remove the libFS.la. Is this the correct method?
