libtool uses '--export-all-symbols' in its link command, which apparently overrides your '-export-symbols sk.sym' option. (BTW, -export-dynamic seems to have no effect in cygwin binutils.) However, including a .def file in the list of objects to be linked will override '--export-all-symbols'.

You need to figure out how to add the .def file to libsk_la_OBJECTS -- I'm not sure how to do that. As far as doing it conditionally (e.g. only on windows) -- first things first: figure out how to add it AT ALL...then worry about conditionalizing it. --Chuck -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Bug reporting: http://cygwin.com/bugs.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
