Problème de portabilité du code Qt4/OpenCV2
Bonsoir,
j'essaie de faire tourner un code c++/qt/opencv sur mon macbook pro
snow leopard. Ce programme détecte les contours d'un flux vidéo via le filtre canny-edge. J'ai réussi à le compiler mais j'ai une segmentation fault à l'exécution. Ce code compile et marche bien sur une debian lenny. Sur Mac,
j'ai du modifier légèrement le Makefile pour intégrer opencv2 :

Apparemment, il y a un problème au niveau de la méthode IplImageWidget::paintEvent

Je crois que sous linux, j'utilise la version 1.0 de opencv et sous mac, c'est la version 2.0. Est ce un problème de compatibilité entre les deux versions ?
Si quelqu'un a une idée ...
Je vous remercie par avance.
