Hello everyone,

I need to play some wavs files in a basic metronome implementation and
i use de Rubygame::Sound class to do that, but I get the following
error:

This error says that your version of SDL is missing the
"SDL_HasMMXExt" function, which Ruby-SDL-FFI (a library used by
Rubygame) expected to find. But, I think that is a bug in
Ruby-SDL-FFI. It should not fail when that function is missing.

Which version of SDL are you using? I'm guessing SDL 1.3, because SDL
1.2 would probably have that function. Am I right? :)

Yes! you are right. I have removed and reinstaled all sdl 1.2 pakages and now it's working fine. Thank you.
