cvShowImage( "Display",img);//Display the image cvWaitKey(0);//wait until user hits a key,if number is +ve then that much milli seconds image will wait to be closed cvDestroyWindow( "Display" );//Destroy and De-allocate memory }

hi i got "sample.cpp:15:47: error: ‘IPL_GAUSSIAN_5x5’ was not declared in this scope" while compiling...please help me to get output...
