Re So you say Larry that i need an import library (foo.lib) to link against in msvc++. I think so also.
My problem is now to create this .lib. Indeed, in the bottom of the link http://cygwin.com/cygwin-ug-net/dll.html, it's explained to create a .def file and .a file, but not a .lib file that i need in msvc++ In fact i don't need a Cygwin-compatible import library but a MSVC++ -compatible import library, because i want to compile my prog with msvc++ (if you ask me why, the simple program is in fact a qt program, and trolltech proposes only compilation with borland C++ and msvc++ which both use .lib import library) maybe there's some docs in the mailing liste archive, but i have great great difficulties with the search engine http://cygwin.com/ml/cygwin/ i search for dll + link and i get weird results, maybe you have some link or good keywords to reach important results ?
