    Default Problems using OpenCV 2.4.3 with QT

    Dear all,

    I am facing problem in using OpenCV 2.4.3 with QT. I downloaded built version of OpenCV 2.4.3 from opencv website. It works with Visual Studio 2010.
    My QT application works when I use old interfaces like IplImage, CvCapture etc.
    I get undefined reference errors, as soon as I start using new interfaces lik cv::Mat, cv::VideoCapture. This is my QT project file including includes and libs for OpenCV:


    Qt Code: 
    1. INCLUDEPATH += C:/OpenCV2.4.3/include/
    2. INCLUDEPATH += C:/OpenCV2.4.3/include/opencv/
    3. INCLUDEPATH += C:/OpenCV2.4.3/include/opencv2/
    4. INCLUDEPATH += C:/OpenCV2.4.3/modules/core/include/
    5. INCLUDEPATH += C:/OpenCV2.4.3/modules/imgproc/include/

    Does any body has faced similar situation How to resolve this problem?


    [EDIT] I build OpenCV 2.4.6 with MinGW/QT support using CMake. I still face the same problem as mentioned above. My application works for IplImage format and give error 0xc0000139 while executing the application.

    Qt Code: 
    1. INCLUDEPATH += C:/2.4.6/install/include/
    2. INCLUDEPATH += C:/2.4.6/install/include/opencv/
    3. INCLUDEPATH += C:/2.4.6/install/include/opencv2/
    4.  
    5. LIBS += -LC:\2.4.6/install/lib/
    6. LIBS += -llibopencv_calib3d290d -llibopencv_contrib290d -llibopencv_core290d -llibopencv_features2d290d -llibopencv_flann290d -llibopencv_highgui290d -llibopencv_imgproc290d -llibopencv_legacy290d -llibopencv_ml290d -llibopencv_objdetect290d -llibopencv_video290d
