Bonjour

Mon but est de charger des images .dds pour texturer mes models 3D. En C et non en C++ (pour le moment)

J'ai un soucis avec la librairie DevIL

J'ai mis ca en include:

#include <IL/il.h>
#include <IL/ilu.h>
#include <IL/ilut.h>
//#include <IL/ilu_region.h>
#include <IL/devil_internal_exports.h>

J'ai bien linker les DevIL.lib, ULUT.lib et ILU.lib que j'ai placé dans le repertoire /lib de mon compilo, et quand je compile j'ai ces erreur:

J'ai renommer config.h.win en config.h car il disait qu'il ne trouvais pas config.h. Apparement, ce IDirect3DDevice8 est informé dans ce fichier mais je pige pas comment resoudre le pb.
- J'utilise Code::Blocks RC1

Sinon si vous avez un moyen d'ouvrire les .dds autrement et en langage C, je suis preneur

Merci

[Laurent Gomila]

Bizarre. A défaut de donner une solution, je ne suis pas sûr que tu aies besoin de ILUT juste pour charger une image, tout comme ILU d'ailleurs.
IL suffira bien largement.

[Sacha999]

re

Oui mais je veux afficher l'image dans ma fenetre OPenGL donc il me semble que j'ai besoin de ILUT (qui a besoin de ILU qui a besoin de IL il me semble), pas seulement la charger en memoire et faire des traitement dessus de facon "invisible"


Je suis passé a "Code Blocks Nighly Build" donc les versions maj tous les jours. Ca me fait les memes messages. Par contre ca compile quand meme et je peux lancé l'executable sans probleme.

Je ne sais pas si ca le faisait avec la version RC2, pensant que ca ne marchait pas. Enfin bref, je vais rester sur la version Nightly qui m'a l'air quand meme plus au point que la version RC2.

Mais j'aimerai bien qu'il ne m'affiche plus ces messages quand je compile, ca fit pas très "propres"

merci


EDIT:
Bon j'ai ouvert le fichier "ilut.h" et j'ai mis en commentaire les blocs suivant:

Je ne sais pas a quoi ca sert, mais au moins je n'ai plus les warnings (c'etait pas des erreurs c'etait des warnings). J'espere ne pas avoir de soucis plus tard a cause de ca.

Si quelqu'un a une meilleure methode je suis preneur ^^

[Laurent Gomila]

Apparemment il faut retirer la définition des macros ILUT_USE_DIRECTX8 et ILUT_USE_DIRECTX9 dans le fichier de configuration (ilut.h ?), puisque tu utilises OpenGL.

[Sacha999]

Je pense qu'en mettant dans mon source a moi

#define ILUT_USE_DIRECTX8 0
#define ILUT_USE_DIRECTX9 0

Et en décommentant le block que j'ai commenté, je pense que ca devrait passer, il verra la valeur a 0, et donc il ignorera le block.
Je testerai ce soir, je ne suis pas chez moi la

[Laurent Gomila]

Non. Il teste si le symbole est défini (#ifdef), pas s'il est différent de zéro (#if xxx != 0). Il faut donc bien retirer sa définition.

[Sacha999]

en effet, j'vais resté avec les parametres
