I've found 2 versions of the "5-step program" instructions to create a .dll and its' .a using ld and dlltool, but I still get "undefined reference" errors from ld. Is there a simple example somewhere I could take a look at? More specifically, I'd love more information on: - the correct link lines (and dlltool lines), - how to generate a .def file automatically (if this is possible), - where to put an entry point function for the .dll so that -e @12 will pick it up successfully (is it necessary to have an entry point at all?), - and whether __declspec(dllexport) is still necessary to export classes and global variables (or if the .def file is sufficient).
