I was build qt4.8.2 libs with opengl for qnx.
My development platform is i.mx53qsb.
When I used the QtOpenGL , I get a issue.

Debug: QQnxScreen: Attached to Device, number of displays: 1
Debug: QQnxScreen: Attached to Display 0, resolution 1024x768, refresh 60 Hz
Debug: QQnxMouseHandler: connected.
Debug: QWSQnxKeyboardHandler: connected.
Warning: QEgl::display(): Falling back to EGL_DEFAULT_DISPLAY
Warning: QEgl::display(): Can't even open the default display

But I can run app about OpenGL without QT.
Now I want to build qt libs with opengl on embedded.
Do you have any suggestion how to do this?
