Thread: OpenCV and Visual Studio 2010: Infamous namespace error.

I don't have a Windows machine handy to test with, but where did you ever read any mention of a "namespace cv"? And where did you find "cv.hpp"?

Try

Code:

#include <cv.h>
#include <cxcore.h>
#include <highgui.h>
#include <iostream>
using namespace std; 


int main( int argc, char** argv )
{ 
//...

Maybe you'll find this opencv wiki helpful.

Okay I have tried that and now these are the errors I'm getting:
