Right. You essentially need to create a "stub" library to link against, typically called an import/export library. You can probably find some references for this in the Cygwin list archives, as Jani suggested, but this is really just pure Windows "stuff". As such, discussion is really off-topic for this list. I'd recommend the MSDN and/or gcc sites as good options for detailed information on this subject, if you need it. -- Larry Hall http://www.rfk.com RFK Partners, Inc.
