J'essaie d'utiliser un QGLWidget dans une application QT, et j'ai ajouté la ligne "QT += opengl" dans le fichier .pro mais j'obtiens maintenant : : error : collect2 : ld returned 1 exit status lorsque j'essaie de compiler mon programme.
la sortie de la compilation montre ce qui suit,
Running build steps for project MapEditor...
Configuration unchanged, skipping qmake step.
