Hello, I am building a SDL binding on MacOS X (but the same problem should appears on Windows). It defines it's own main function in a libSDLmain.a. But I can't get ghc not to generate a main when linking with -lSDLmain, which is the option that is indicated to get the main function that make SDL usable. when I link write : ghc -o test Main.hs libSDLmain.a , ghc doesn't generate a main as it can see there is a main in libSDLmain. And my test programs works. but when I write ghc -o test Main.hs -lSDLmain, ghc creates its own main, and it doesn't work. The first solution is not convenient as the standard way of getting parameter is "sdl-config" which gives back the second types of argument. -no-hs-main don't change anything on this point. Is there a flag saying ghc not to generate a main? Cheers, Nicolas Oury
