I haven’t tried in a while, but the problem is that on OS X, the SDL library defines its own main() which invokes the user-provided main(), and the C header file does #define main _SDL_main to make this “work” as long as an FFI isn’t involved.

I checked the SDL Mercurial repo, and it still does this:

http://hg.libsdl.org/SDL/file/74356aed1fa2/include/SDL_main.h http://hg.libsdl.org/SDL/file/74356aed1fa2/include/SDL_main.h

So yes, the problem still exists. There is no easy workaround, either; for Haskell code to run as a library rather than an executable requires a special wrapper in C to initialize the runtime.

L.S.,

Does the problem with SDL on OS X, as mentioned on the HaskellWiki page about SDL[0], still exist? This text is quite old and I would like to remove it.
