How to Display image on pixmapLabel use openCV library

Hello, I want to display image from file location on "pixmapLabel" use openCV library. Here is my code, but I have some error message when I compile it. The error message just like this :
"undefined references to call cvLoadImage......bla...bla...bla...."

I have included the openCV library path. Can you help me to fix the problem?? I will appreciate your help.

//----------------------------------------------------------------------
#include "/usr/local/include/opencv/cv.h"
#include "/usr/local/include/opencv/highgui.h"

void FormMain::loadOpenCV()
{
IplImage* img = 0;
img=cvLoadImage("/home/ton_malaka/snapshot1.png");
pixmapLabelOut->setPixmap(img);
}
//---------------------------------------------------------------------------

Hi

I am just trying to answer donnow whether its correct or False.
In QT we can either upload an image or a QRC file
Just try to do this using QT designer and see the generated code, it ll help you

Sorry, if it doesnt clear your doubt!

Hi Alokraj,

Thank you for your reply. Actually in Qt we can upload and display image without openCV library, but I need openCV to process edge detection using Canny Algorithm.
