Quelqu'un saurait-il m'aider comment le rendre compatible sous vista? Faut-il modifier le makefile ou c'est eclipse qui pose problème?

MERCI d'avance

La source de tes maux :

..\framebuffer.h:16:19: FL/gl.h: No such file or directory

Il faut que tu configures correctement ton INCLUDE_PATH (as-tu installé les libs de dev opengl, déjà ? )

[loufoque]

Des fois il y a des flags pour le preprocesseur à passer pour utiliser certaines bibliothèques.

Des commandes comme `pkg-config --cflags bibliothèque` fournissent ces informations, par exemple.
`pkg-config --libs bibliothèque` quant à lui fournit la liste des bibliothèque à lier et leur chemin.
