Bonjour à tous,
Je suis en train de créer un éditeur pour mon petit projet de jeu, et pour cela j'ai voulu coupler SFML 2.0 avec Qt 5.0.1.
Seulement, j'ai déjà un problème de compilation avec un code qui devrait en théorie fonctionner:
QSFMLCanvas.hpp
#ifndef QSFMLCANVAS_HPP

{

Avec ce code le charmant compilateur me transmet ce message, tout en finesse:

Voilà, il me semble que toutes les informations à ma connaissance sont là.
Est-ce que vous sauriez comment résoudre cette erreur?
