Your linker command for making the dll is correct, so I am sure that the c source is the problem. Is the function you are trying to load marked as "extern" ? Steven Original Message: I used nm, see below. Obviously you are right, no exported symbols. I guess that nm doesn't see the symbols of a MSVC++ 6.0 compiler. At least that dll works. How do I define which symbols are exported? (This is probably a beginners faq, but hey, it's my first dll ;-) ) [Administrator@lisi]/lib/gnupg:{505}: $ nm --defined-only idea.cyg.dll |grep SYMBOL (nothing) [Administrator@lisi]/lib/gnupg:{506}: $ nm --defined-only idea.msvc.dll |grep SYMBOL nm: idea.msvc.dll: no symbols -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Bug reporting: http://cygwin.com/bugs.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
