Cosima vizualization error on Docker hosted on Mac OSX

[scandey]

I am attempting to run the experimental docker image on a Mac OSX 10.14.6 host. XQuartz is properly setup, as geomega works without any issues. When I attempt to run the sample visualization code, I get a series of errors to do with OpenGL.

From a new Docker image, running cd $MEGALIB/resource/examples/cosima/macro and cosima -m Visualize.mac Visualize.source appears to work till "Execute macro...!". Some OpenGL errors are mentioned, but then the simulation proceeds regardless. After storing about 5 events, a final error is given and nothing is displayed. The final error is ERROR: G4VisCommandsViewerSave::SetNewValue: no current viewer.. The rest of the errors from the top of the output are shown below.

If there are additional logs for OGL or MEGAlib I should include, please let me know.

Hi,

It looks like the docker does not support openGL. Googling tells me, that this requires the creation of a new dockerfile with openGL support. An example what would need to be added might be here:

When I find the time I will do it, but not in the immediate future. If you have time, feel free to modify the Dockerfile yourself. It is in the config subdirectory.

Best,
Andreas
