Je suis en train de se OpenCv2.4.6 à travailler avec QT5.1.0 J'ai suivi ce guide jusqu'à Qt creator 5.0.1 with OpenCv 2.3.4 on windowsOpenCV 2.4.6 avec QT 5.1.0 Erreurs
Unfortunatly après avoir fini d'essayer l'exemple d'application (afficher une image en utilisant OpenCV dans le QtCreator je reçois ces erreurs:
[Project-Path]\main.o:-1: In function `main':
[Project-Path]\main.cpp:8: error: undefined reference to `cv::imread(std::string const&, int)'
