Ensuite crée un nouveau projet.
Dans l´onglet " multimedia", choisi " sdl"
Entre un nom et crée le.
Une fenêtre s´ouvre avec du text.
Tu effaces tout et tu fais copier coller de ceci dedans :
- include < stdio.h>
- include < stdlib.h>
- include < windows.h>
- include < string.h>
- include < math.h>
- include " SDL.h"

C´est u petit " state of the art" effect 
( au fait efface " libiberty.h" quand tu crée un nouveau projet : il est manquant )
