Hello Guys,

I have a Qt application in which I have used opengl to display opencv video on qt central widget in windows machine but now I have ported this application into raspberry pi and while compiling this app I am getting error like "glRaster2i, glOrtho, glDrawpixels not declared in this scope" if anybody have any idea regarding this error then please let me know. I will appreciate your help.

Thanks
