I'm trying to install OpenCV. Turns out this is far more complicated as expected. The tutorials are all outdated. Here is my current problem:

I'm running on a 64 bit machine, and am trying just a simple sample code:

#include <opencv\cv.h>
#include <opencv\highgui.h>

using namespace cv;

int main() {
    Mat image;

    VideoCapture cap;;


    while(true) {

        cap >> image;

        imshow("window", image);


    return 0;

When I run this, I get an error stating that opencv_core248d.dll is missing. Checking the bin directory, it is there. How do I fix this?

This works. But is there no way to link the libraries?

I also installed OpenCV recently, without (many) problems

Did you update the system path to include the %OPENCV_DIR%\bin directory? see:

Yes, I have done that. Same error.
