To do this: nm --demangle --defined-only someMSlib.lib | grep CloseDirectory You can only do the with the MS .lib not the Borland .lib, they have different formats or headers. My guess is that the .def is incorrect. It is just a guess. Earnie. earnie_boyd@hotmail.com ---Dale Smith wrote: > > Greetings! > > I hope this is the right place to ask mingw32 questions.
