Problem:

I have a project which uses the Raspberry Pi camera and OpenCV to doing some analysis. However, when I want to display the image (with the OpenCV API/a ROS node), there ' s an error saying

Window System doesn ' t support OpenGL

Solutions:

Raspberry Pi doesn ' t come with OpenGL support by default, but it's a simple installation. I believe you the just need to install Libgl1-mesa-dri. Can do this at the command line Using:code:

$  apt-get Update
$  apt-get Install Libgl1-mesa-dri
