I've compiled Hexen2 game for Maemo5
It works great and I don't get any error on scratchbox
But now I've uploaded the source to Extras Builder and I get this:

error: SDL.h: No such file or directory

I've tried
-I/usr/include/SDL
/usr/bin/sdl-config --cflags'

Nothing seems to work
Can somebody help me?
Thanks
