Shortly no. Longer answer is yes it does. I rember writing a few articles about this... Basicaly thing goes so that you compile (but not link) needed files, generate needed .lib:s and then link whole thing. Note that you can export symbols from .exe in same way. Here is few pointers: And bad news is: libtool can't handle this (at least not to my knowledge).
