The Rc file is mainly for your layout and strings so I don't think you need one for a dll, don't take that to the bank but I have made libraries with out them.

Where can I find documentation on the formats of .def and .rc files? For liblouis I should only need an EXPORTS sections in the .def file. For liblouisutdml I will also need an IMPORTS section. Is this correct? Do I need a .rc file just to make the dlls? Thanks, John -- John J.
