Salut, comme mon titre l'indique, j'ai une grosse erreur de compilation. Le probleme c'est que j'ai aucun Warning, le debug ne me dis pas où se trouve le probleme. J'ai juste un

||=== Build: Debug in prj (compiler: GNU GCC Compiler) ===|
||error: ld returned 1 exit status|
||=== Build failed: 1 error(s), 0 warning(s) (0 minute(s), 2 second(s)) ===|

Le code est un example donne par le site.:

Pour l'utiliser il faut avoir deja sfml >2.4 dans son projet

Bonjour,

En général ce type d'érreur est du à une mauvaise gestion des librairies externes. Tu compile en static? en l'absence d'une des librairies exigé ca peut. Expliquer cette erreur.

Si non l'autre erreur possible serait l'utilisation d'un type (ou fonction) qui porte le même nom dans la STL (STD ) Et dans SF.

Je suis pourtant sur d'avoir bien suivi le tuto sur sfml.

Tu sais comment je peux faire donc??

Bonjour,

si tu as encore ce projet, tu pourais me dire si tu compile en static, dans ce cas tu devrais rejouter les DLL utilles en dependances lors de la compilation. Si non tu les rajoute a dans le repertoire de l'executable final ( l'erreur normal ici c'est xxx.dll is missing )

Ah j'ai regle le probleme deja. C'etait un probleme avec des dll qui manquait : openal32 et gdi, les deux sont dans le repertoire System sur Windows mais fallait apparemment indiqué leur chemin au moment d'inclure les "libs"
