Édition des liens avec OpenCV

Bonsoir ,

J'ai déja terminer mon application en utilisant QT Creator et la bibliothèque OpenCV sur le système linux .

Mais maintenant j'essayer d’intégrer mon application sur windows 7 64bits de même avec QT Creator . et j'ai rencontrer des probéleme de linker avec la bibliothèque OpenCV .
voila mon .pro

Code:

Merci de me aider .

Bonjour,

Il semble qu'il ne prenne pas en compte les lignes :

Citation:

---

LIBS += -LC:\opencv\build\x64\mingw\lib \
-lopencv_core240 \
-lopencv_highgui240 \
-lopencv_imgproc240

---

lorsque l'on regarde :

Citation:

---

g++ -enable-stdcall-fixup -Wl,-enable-auto-import -Wl,-enable-runtime-pseudo-reloc -mthreads -Wl -Wl,-subsystem,windows -o debug\Detect.exe debug/main.o debug/mainwindow.o debug/morphofeatures.o debug/detect.o debug/basicocr.o debug/preprocessing.o debug/recognition.o debug/moc_mainwindow.o -L"c:\QtSDK\Desktop\Qt\4.7.3\mingw\lib" -lmingw32 -lqtmaind -lQtGuid4 -lQtCored4 -LC:\OpenSSL-Win32_full\lib

Mais je ne vois pas pourquoi :?

A mon avis le x64 y est pour quelque chose, tu ne peux pas compiler de version 64bits avec un compilateur 32bits, un Qt 32bits...

Bonjour ,
Merci pour vos aides ,

En fait mon compilateur MinGW est 32bits donc il faut faire la liaison avec x86/mingw .
Donc :
1 - j'ai coller mes lib nécessaire (libopencv_core240.dll.a ; libopencv_highgui.dll.a ; libopencv_imgproc.dll.a ; libopencv_ml240.dll.a )pour mon projet dans la répertoire des lib de Mon compilateur MinGW chez moi (
"C:\QtSDK\Desktop\Qt\4.7.3\mingw\lib")
2- pour la configuration du projet .pro
Code :Sélectionner tout - Visualiser dans une fenêtre à part

Code:

---

1 2 3 4 5 6 7

win32{ LIBS += -lopencv_core240 \ -lopencv_highgui240 \ -lopencv_imgproc240 \ -lopencv_ml240 }

---

et les erreurs de "undefined reference " sont disparus
l’exécutable a été créer mais
mais voila le résultats de lancement
L'application n'a pas réussi à démarrer correctement (0xc000007b)

Quelqu’un a une idée ? SVP

1) Ça ne se fait pas de déplacer des libs n'importe où pour arriver à ses fins (tu vas t'y perdre). Tu avais la bonne méthode au-dessus avec le -L<dossier des libs>, fallait juste mettre x86 au lieu de x64 je suppose.

2) Ok tu as compilé avec succès. Pour l'exécution, il faut copier les dépendances (les 4 dll et leurs dépendances) à côté de l'exécutable (ou en environnement de développement, les rajouter dans le PATH pour éviter de les copier pour chaque projet).
