Bonjour,

J'essaie d'utiliser SDL2_mixer mais à chaque fois que je met le code pour l’initialiser, le programme ne fonctionne plus. Je débute et j'ai commencé depuis peut avec la SDL1, sur un code simple ou j'ouvre une fenêtre j'arrivais à jouer des sons et des musiques avec SDL mixer 1. Je suis passé récemment à la SDL2 et donc depuis à la version 2 de SDL mixer et la rien à faire, sans le code d'initialisation de mixer la fenêtre s'ouvre normalement et reste ouverte mais dès que je l’initialise la fenêtre apparait à peine 1 seconde et le programme se ferme aussitôt. Et ça avec plusieurs programme différent et sur plusieurs PC différent. Je voulais savoir si il y avait un problème avec cette version (la 2.02) et si il était préférable d'utiliser une autre version ? ou si c'était autre chose, d'avance merci.

Bonjour,

Je pencherai pour un problème de DLL manquante, mais je ne suis pas sur.
Sinon, utilisez vous la SDL 1 ou SDL 2 ?

[Alma9]

J'utilise la SDL2, la version i686-w64-mingw32 pour toutes les versions de SDL2 (image, TTF, mixer). Mon OS windows 7 et aussi 10 en 64bit. J'associe à mon projet les DLL correspondantes. J'aimerais savoir si quelqu'un arrive à utiliser SDL2 mixer et si oui lequel il utilise, la version et le format i686 ou x64 ? Je me suis pas trop penché sur la x64, peut être que la solution est là.

[LittleWhite]

Il faut bien prendre les i686.
Pouvez-vous préciser ce qui se passe lorsque "ça fonctionne plus" ?

[Alma9]

Quand ça fonctionne une fenêtre s'ouvre avec une image de fond mais quand j'ajoute ceci

 int flags = MIX_INIT_MP3;
    int initted = Mix_Init(flags);
    if ((initted & flags) != flags)
    {
        printf("Mix_Init: Failed to init SDL_Mixer\n");
        printf("Mix_Init: %s\n", Mix_GetError());
        exit(1);
    }
 
    /* Open 44.1KHz, signed 16bit, system byte order,
    stereo audio, using 1024 byte chunks  */
    if (Mix_OpenAudio(44100, MIX_DEFAULT_FORMAT, 2, 1024) == -1) {
        printf("Mix_OpenAudio: %s\n", Mix_GetError());
        exit(1);
    }
 
    // Définit le nombre de pistes audio (channels) à mixer
    Mix_AllocateChannels(32);

une fenêtre blanche apparait moins de 1 seconde et le programme est terminé. Je tiens à préciser que ce n'est pas moi l'auteur, c'est un code que j'ai trouvé sur internet quand je cherchais un projet qui fonctionnais avec SDL2 mixer pour voir comment c'était fait (il faut rendre à César ce qui appartient à César).
J'ai essayé avec un de mes codes et la j'ai plein d'erreur

Du coup, peut être que la console affiche une erreur pour indiquer que cela ne s'est pas initialisé correctement.
Pour vos erreurs de compilation, c'est que votre édition de liens est mal configuré.

Très bien je ferais d'autres tentatives, merci.
