opencv error according to opengl

[jhchris713]

With using docker image and container which you provided, the opencv error occurs in following step.

xhost + nvidia-docker run -it -e DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix --mount type=bind,source=$MATTERPORT_DATA_DIR,target=/root/mount/Matterport3DSimulator/data/v1/scans,readonly --volume pwd:/root/mount/Matterport3DSimulator mattersim:9.2-devel-ubuntu18.04 cd /root/mount/Matterport3DSimulator rm build mkdir build && cd build cmake .. make cd ../ ./build/tests ~Timing

outputs following opencv error.

This issue was posted once before, but seems not figured. https://github.com/peteanderson80/Matterport3DSimulator/issues/33

Without interactive demo, this issue seems minor issue.

@jhchris713, could you please share how you managed to cope with the problem?

I am facing the same issue, and can't use the docker image since I have a lot of other dependencies running. What is the solution for "OpenCV Error: No OpenGL support (Library was built without OpenGL support) in cvNamedWindow"?
