I was following a tutorial on web for an OpenCV library to detect eyes
when i compile it this error appears I tried to fix it but didn't find a
solution.
main.cpp:59:1: error: ‘capture’ was not declared in this scope capture = cvCaptureFromCAM( 0 );
The code is long I put only the part that I think causing this error [Full code](http://pastebin.com/xUTFiuiu)
Thanks
