J'essaie de compiler un logiciel de caméra pour la caméra uEye en utilisant qmake et make.Référence indéfinie à `Histogramme :: Histogramme (QWidget *)
Mes commandes qmake fonctionne très bien, mais je reçois l'erreur suivante quand je tape dans la ligne faire de commande
make[1]: Entering directory '/usr/src/ids/ueyedemo'

Quelqu'un peut-il me dire où le problème est peut-être? Je pense que je pourrais avoir la mauvaise version de qt ou de qmake?
