Try to use the latest version of OpenCV i.e. 2.4.3....however right now you can try to link the debug libraries e.g. opencv_core2.4.xd and run the program to get the Mat image format working.

what is the version of opencv you are using? try the following code and test...get some picture and run it....

#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>

using namespace cv;

int main()
{
  Mat im = imread("C:\\some_picture.jpg");
  if(im.empty())
     return -1;
  imshow("TEST",im);
  waitKey();

  return 0;
}

Your main() signature is incomplete

try

int main(int argc, char* argv[])

these parameters represent:

argc  // an int indicating the number of arguments passed in to the function

argv[]  // an array of character strings, the actual arguments.

The first argument argv[0] is the program name ... so argc is always a minimum of 1.

The second argument, argv[1] will be the first argument your user passes in, bringing argc up to 2. That is what your program is expecting, a single argument from the user, argc == 2.
