Hi, Please, use the Dll import/export macro of kmdidefines.h. It works with Win32 and Unix. The macro should be added to all classes which are public from a Dll on Win32. Take a look at the KMdi version in kdevelop/lib/qextmdi which worked for me on Win32 at least in October. (It's cool to have KMdi on Win32 as gdb sucks and MSVC debugger rules. :P Usually, I develop KMdi on Win32 and port back to Linux. What a strange world....)
