Hi,

I have been trying to do the same thing some time ago, also without
luck. Just as you have, I have been able to create a .dll (with the
corresponding .a file for linking). Running a simple test program did
not crash in my case, but the classes that were defined in the .dll
were not available, as I got the message:

objc runtime: cannot find class X

Have you also had this problem?
