hey everyone

i followed all the step given in the guide but when i try the code:

include <opencv2 core="" core.hpp="">

include <opencv2 highgui="" highgui.hpp="">

include <iostream>

using namespace cv; using namespace std;

int main( int argc, char** argv ) { if( argc != 2) { cout <<" Usage: display_image ImageToLoadAndDisplay" << endl; return -1; }

Mat image;
image = imread(argv[1], IMREAD_COLOR); // Read the file

if(! image.data ) // Check for invalid input
{
    cout << "Could not open or find the image" << std::endl ;
    return -1;
}

namedWindow( "Display window", WINDOW_AUTOSIZE ); // Create a window for display.
imshow( "Display window", image ); // Show our image inside it.

waitKey(0); // Wait for a keystroke in the window
return 0;

}

it gives me the error cannor open or include opencv2/core/core.hpp no such file or directory !!
