Error Undefined reference to Symbol

Good morning I'm studying the Opencv library for computational view in Ubuntu 14.04 I'm using Eclipse Mars.2 programming in C ++. The following error appears:

  

./ image.o: undefined reference to symbol   '_ZN2cv6imreadERKNS_6StringEi'

My code is below

#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 Tom.jpg" << endl;
     return -1;
    }

    Mat image;
    image = imread(argv[1], CV_LOAD_IMAGE_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 tried everything but did not get anything. I have no idea what's going on. Thanks for getting answers.
