I faced a similar problem not long ago. Make sure you use the result of
sdl-config --cflags during build time and that you properly include SDL by
doing :
#include <SDL.h>
and NOT
#include <SDL/SDL.h>

I was debugging a small opengl app that worked for the one who wrote it and
failed on my computer with a black window like you.
