Salut tout le monde !
Voila j'essaye de coder un petit "music player" en C++ avec Qt pour la GUI, et IrrKlang pour l'audio. J'ai lu et revérifié 50 fois mon code, mais je ne trouve pas l'erreur, ca me rend fou !
Le compilateur me dit :
virus721@area721m:~/Workspace/qt/music_player$ g++ -c -pipe -O2 -Wall -W -D_REENTRANT -DQT_NO_DEBUG -DQT_GUI_LIB -DQT_CORE_LIB -DQT_SHARED -I/usr/share/qt4/mkspecs/linux-g++ -I. -I/usr/include/qt4/QtCore -I/usr/include/qt4/QtGui -I/usr/include/qt4 -I. -I. -lIrrKlang -I /usr/include/irrklang -o main.o main.cxx

Mon programme compte les fichiers suivants :
main.cxx
MP_MusicPlayer.h / cxx
(objet contenant un pointeur vers les elements du music player : l'interface, le moteur audio, et le gestionnaire de playlists)
MP_GUInterface.h / cxx
(objet constituant l'interface graphique,. Cet objet demande au moteur audio de jouer, mettre en pause ou stopper le morceau de musique en cours. Si il faut changer de morceau de musique, il demande d'abord au gestionnaire de playlist le nouveau morceau a jouer avant de demander au moteur audio de le jouer,)
MP_AudioEngine.h / cxx
(objet contenant un pointeur vers un moteur audio de IrrKlang. Cet objet ne fait que lire, mettre en pause ou arreter le morceaux qu'on lui envoie)
MP_PlayListMgr.h / cxx
(objet stockant le morceau et la playlist en cours)
MP_PlayList.h
(objet représentant un playlist (un ensemble de MP_Tracks), pas encore codé)
MP_Track.h
(objet représentant un mocreau de musique (nom, auteur, chemin du fichier etc), pas encore codé).
Chacon des trois objets principaux contient un pointeur vers le "MP_MusicPlayer" qui les "contient". Je sais plus trop pour quoi j'ai mis les choses de cette manières mais bon je doute que le probleme vienne de la :P

Si quelqu'un avait quelques minutes pour m'aider, ce serait tres sympa !
EDIT : désolé pour les indentations manquantes et les simleys au milieu du code mais je ne connais pas les balises conservant la mise en forme x)
