I have typed the following program from Learning OpenCV book:

#include "highgui.h"
    
    int main(int argc, char *argv[])
    {
      IplImage *img = cvLoadImage(argv[1]);
      cvNamedWindow("Example1", CV_WINDOW_AUTOSIZE);
      cvShowImage("Example1", img);
      cvWaitKey(0);
      cvReleaseImage(&img);
      cvDestroyWindow("Example1");
    }

When I try to build it using `Eclipse CDT`, I get the following (Any ideas?):

Thanks.

It appears that this is just a little compiler flag mismatch. You should follow the instructions here, and it should work.

You need to include header file...

#include "cv.h"

Thanks for your replies. Actually, neither solutions worked.

Thinking back had same problem with OpenCV 2.0. I could get it to work correctly with code::blocks 8.02 & MinGW 3.4 installed, also got it working with netbeans IDE had to do as Mike 2000 17 suggested.

There's a tutorial on netbeans c++ forums I wrote to install OpenCV 2.0 with netbeans IDE

Hope this helps
