I am a beginner for Eclipse. I now have Eclipse C/C++ IDE with OpenCV library running on Windows 7. So far it works after spending hours trying to get it running. But then I realize that Eclipse does not pop up a command prompt as VS2010 does while debugging. And moreover Eclipse's debug mode is just stuck in there and refuse to output anything. But if the code doesn't involve the OpenCV things it works again.

Below is the code I use for testing. It captures images from webcam and output it to the screen. The infinite loop (until you press 'q') makes sure it constantly grabs new inputs from the camera.

I browsed through the workspace and run the exe just compiled and it worked flawlessly. So I don't think there's anything wrong in the code (it's an example code anyway

In brief, can I just pop up a command prompt window in debug mode? And why is Eclipse console stuck when the code involves some OpenCV functions?

#include <stdio.h>
#include <stdlib.h>
#include <tchar.h>
#include <cv.h>
#include <cxcore.h>
#include <highgui.h>
#include <iostream>

int _tmain(int argc, _TCHAR* argv[])
{
    CvCapture *capture = 0;
    IplImage  *frame = 0;
    int       key = 0;

    /* initialize camera */
    capture = cvCaptureFromCAM( 0 );

    /* always check */
    if ( !capture ) {
        printf("Cannot open initialize webcam!\n");
        return 1;
    }

    /* create a window for the video */
    cvNamedWindow( "result", CV_WINDOW_AUTOSIZE );

    while( key != 'q' ) {
        /* get a frame */
        frame = cvQueryFrame( capture );

        /* always check */
        if( !frame ) break;

        /* display current frame */
        cvShowImage( "result", frame );

        /* exit if user press 'q' */
        key = cvWaitKey( 1 );
    }

    /* free memory */
    cvDestroyWindow( "result" );
    cvReleaseCapture( &capture );

    return 0;
}
