Question

Anytime I call cvNamedWindow I get a segmentation fault and I don’t know why it happens. I’ve tried compiling online code samples as well as writing my own. Here’s a minimal piece of code that reproduces the problem:

#include <opencv2/opencv.hpp>

int main() {
    cvNamedWindow("Video");
    return 0;
}

cv::namedWindow("Video") doesn’t work either. Why does this happen? I’m compiling with OpenCV 2.3.1 under MinGW (C++ compiler v4.6.1) with Qt Creator.

Answer 1

I’m assuming the problem is related to another thread I posted. Long story short, my other problem had to do with a difference between debug and release DLLs that I didn’t know about.
