Hi. Write on QT and use version OpenCV 2.4.13. Today, with a problem. When you start the program, fails with the following error:

D:\delo\po-russian\po-russian\sglazhivanie.cpp:31: error: undefined reference to `cvSmooth'

and

collect2.exe:-1: error: error: ld returned 1 exit status

#include <cv.h>
#include <highgui.h>
#include <stdlib.h>
#include <stdio.h>

IplImage* image2 = 0;
IplImage* dst = 0;

int main(int argc, char *argv[])
{

   const char *filename = argc == 2 ? argv[1] : "C:\deva.jpg";

    image2 = cvLoadImage(filename, 1);


    dst = cvCloneImage(image2);

    std::cout << "[i] image: %s\n" << filename;
    assert( dst != 0 ); 



    cvNamedWindow("original", CV_WINDOW_AUTOSIZE);
    cvNamedWindow("smouth", CV_WINDOW_AUTOSIZE);


    cvSmooth(image2, dst, CV_GAUSSIAN, 3, 3); //THIS ERROR - - - - - - - 


    cvShowImage("original", dst);
    cvShowImage("smouth", image2);

    cvWaitKey(0);


    cvReleaseImage(& image2);
    cvReleaseImage(& dst);


    cvDestroyWindow("original");
    cvDestroyWindow("smouth");

    return 0;
}
