J'essaye de relier mon application QT à une DLL (libshout), tout en construisant pour Windows.Compilation de libshout en utilisant QT/qmake
J'ai ajouté les lignes appropriées à mon dossier .pro:
LIBS += -L/local/lib -lmp3lame
LIBS += -L/local/lib -lshout
LIBS += -L/local/lib -logg
LIBS += -L/local/lib -lvorbis
LIBS += -lwsock32
J'ai aussi construit avec succès et installé à libshout/local/lib (j'utilise MinGW et le compilateur gcc-DW2).
Cependant, qmake ne parvient pas à lier correctement. J'ai collé la sortie gcc/make ci-dessous. Je ne suis même pas sûr qu'il essaie de lier à la bonne bibliothèque (n'est pas une bibliothèque statique .a/.la?).
J'ai déchire mes cheveux pendant 3 jours sur celui-ci de sorte que toute aide appréciée :)
