I have a project which uses the raspberry pi camera and openCV (also: ROS) to do some movement analysis. However, when I want to display the image (with the openCV API or a ROS node), there's an error saying
window system doesn't support opengl
And that happens although the openGL test-programs as well as raspistill work perfectly. I already tried installing openCV 2.7 from source and getting the ros-desktop packages, but nothing worked until now.
I'm using C++ to program everything, not python.
Thanks in advance
