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 AT lisi]/lib/gnupg:{505}:
$ nm --defined-only idea.cyg.dll |grep SYMBOL
(nothing)
[Administrator AT lisi]/lib/gnupg:{506}:
$ nm --defined-only idea.msvc.dll |grep SYMBOL
nm: idea.msvc.dll: no symbols

Thanks

     Volker
