I tried to compile 2ooM under MinGW and under Mandriva Linux 2006.0. I allready knew libSDL, libSDL_image and fmod is needed, but obviously that's not everything... Something is still missing. It didn't want to compile :-(
So could you perhaps put a list of that libs you are using in this thread or on your page?
Another queer thing was, that few files wasn't linked with SDL.h but with SDL/SDL.h so I had to make a copy in a second folder.
Greetings and keep on working :-)
