I've built glibmm just fine, and I had something defined under this
macro. It was possible to compile either by removing this or by
undeffing and defining empty GLIBMM_API . I just can't imagine what
could be there from VC++ point of view. If it is declared as static it
resides in compiled unit and is of single copy when linked. AFAIK
another alternative is to declare it extern and then export symbol from
shared library.

I think I used second to the latest.

Ah! I didn't even look into 'bad' plugins :-)

Thanks! Kalev Lember helped me on IRC to get started with Fedora repo.

Do you plan to make installer for MS VC++ as well? or mingw only?
