Hi,

I am new to the group and OpenCV. I am coding the tutorial found in http://docs.opencv.org/doc/tutorials/introduction/windows_visual_studio_Opencv/windows_visual_studio_Opencv.html I am setting the Configuration: to Debug and Platform: to x64. Here is what the code in Visual C++ looks like:

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;

}

I also made sure that the following library directories were added to the linker: C:\OpenCV\opencv\build\x64\vc12\staticlib C:\OpenCV\opencv\build\x64\vc12\lib

and the following libraries were added to Additional Dependencies for the Debug platform: opencv_core249d.lib opencv_imgproc249d.lib opencv_highgui249d.lib opencv_ml249d.lib opencv_video249d.lib opencv_features2d249d.lib opencv_calib3d249d.lib opencv_objdetect249d.lib opencv_contrib249d.lib opencv_legacy249d.lib opencv_flann249d.lib

and the following libraries were added to Additional Dependencies for the Release platform: opencv_core249.lib opencv_imgproc249.lib opencv_highgui249.lib opencv_ml249.lib opencv_video249.lib opencv_features2d249.lib opencv_calib3d249.lib opencv_objdetect249.lib opencv_contrib249.lib opencv_legacy249.lib opencv_flann249.lib

When I tried to build this C++ file using the x64 platform, I got 116 unresolved externals (error LNK2019). Is there something I am missing?
