Question

I use Eclipse CDT for developing C with mingw. I also add opencv libary. Everything compiled without problems. But if I start the compiled application (using a opencv-function) there is an init error. If I only include the .h-files without using a function it works.

The code:

#include <opencv2/opencv.hpp>
using namespace std;

int main() {
    cout << "!!!Streaming!!!" << endl; // prints !!!Streaming!!!
    // Nothing but create a window
    cvNamedWindow("mainWin", CV_WINDOW_AUTOSIZE);
    cvMoveWindow("mainWin", 100, 100);
    cvWaitKey(0);
    return 0;
}

If I do not use a cv.. – function there will be no init error. Even if I include opencv2/opencv.hpp

I do not have an idea how it works.

Hope you can help.

I found the solution. The opencv-dll-files for mingw are damaged. I rename the visualstudio dlls to the names of the mingw-dlls and put it directly to in the exe folder and it works.
