I think the issue can rather be concerned with the use of SDL. As I mentioned above, when I link using gcc -o slayer.exe file.o font.o image.o input.o slayer.o symbols.o video.o -mwindows -lmingw32 -lSDLmain -lSDL -lSDL_image -lSDL_ttf -lguile-2.0 the linkage succeeds. Note that, although the -D option shouldn't have any influence on the linkage, it does replace main with SDL_main during the compilation of object files, and I think it's the SDL_main library that contains the actual entry point. However, the question is not how to get the things built (because I already managed to do so), but how to adjust the build system (i.e. configure.acand/or various Makefile.am files) so that it builds the things properly. In particular, I didn't put the -mwindows there in the first place, so I have no option to remove it or replace it. regards, M.
