Hi, basically I'm starting learning on how to writing c++ code using openCV to load an image in QT creator tool.

for your information, I create a project called TestingOpenCV, with several .cpp and .hfile :
- .h file:
--- mainwindow.h
--- testing.h
- .cpp file
--- main.cpp
--- mainwindow.cpp
--- testing.cpp (problem occur here...)

in TestingOpenCV.pro

TARGET = TestingOpenCV
TEMPLATE = app

using namespace cv;

    string address = .... // state the address to retrieve the image1
    string imgFile = address + "image1.jpg";

/*     E R R O R     H E R E . . .     */
    Mat image;
    image = imread(imgFile, CV_LOAD_IMAGE_COLOR); // Read the file

    if(! image.data)                      // Check for invalid input
    {
        cout <<  "Could not open or find the image" << endl;
    }

    namedWindow( "Display window", WINDOW_AUTOSIZE ); // Create a window for display.
    imshow( "Display window", image );                // Show our image inside it.

    waitKey(0); // Wait for a keystroke in the window
/*     E N D     O F     E R R O R     */
}

although I build this program with no error, However, when I run this program...

it state that:

Starting C:\Users\user\Desktop\Qt_Stuff\build-TestingOpenCV-Desktop_Qt_5_0_2_MSVC2010_32bit-Debug\debug\TestingOpenCV...

The program has unexpectedly finished.

C:\Users\user\Desktop\Qt_Stuff\build-TestingOpenCV-Desktop_Qt_5_0_2_MSVC2010_32bit-Debug\debug\TestingOpenCV exited with code -1073741515
