Bonjour tout le monde,

J'ai un problème de linkage d'OpenCV, j'utilise les librairies static (.a), et je n'arrive pas à faire le linkage dans le fichier (.pro), est ce que quelqu'un a une idée? Je vous remercie d'avance.

Le fichier .PRO:

Code :

TARGET = Test
    target.files = Test
    target.path = /home/root
INSTALLS += target
 
TARGET = Test
TEMPLATE = app
 
#INCLUDEPATH += "/usr/local/include/opencv" "/usr/local/include/opencv2"
#LIBS +=  -lopencv_core -lopencv_imgproc -lopencv_highgui -lopencv_ml -lopencv_video -lopencv_features2d -lopencv_calib3d -lopencv_objdetect -lopencv_contrib -lopencv_legacy -lopencv_flann

SOURCES += main.cpp \
        mainwindow.cpp \
        Test2.cpp
 
HEADERS  += mainwindow.h
 
FORMS    += mainwindow.ui

et voici les erreurs que ça génére:

Bonjour,

Comment avez vous récupérer OpenCV et les .a associés et quel est l'architecture de votre machine ?
