OpenCV : undefined reference to imread()

Question

I have configured OpenCV 3.1.0 in Eclipse Mars. These are my configuration,

G++ includes: D:/opencv/build/install/include; GCC includes

Answer 1

I recommend to link the following libraries:

opencv_core
opencv_highgui
opencv_imgproc
opencv_imgcodecs

And in the .cpp file, you can include like this

    #include 
    #include 
    #include 
    #include 

    using namespace std;
    using namespace cv;

Or

    #include 
    #include 

    using namespace std;
    using namespace cv;
