   I'm trying to figure out how to use OpenGL within Docker without opening a window, but when I attempt to compile my shaders it throws an error.

   Any tips?

   Searches are coming up short.

   I plan to extract the rendered pixels to save as an image, & I have an image library in mind.

   Boosts appreciated!

   (I'm working in Haskell, but I can pull in C functions especially for one-off calls)

     If you use podman via toolbox, you should have all the necessary bits setup for OpenGL device access to work.

     I use that occasionally when doing work on GTKs OpenGL renderer in a container.

     @hergertme Discussing with a collaborator, we'd like a look at that container you use for testing GTK?

     @alcinnz maybe offscreen rendering or Xvfb?

     @cybertailor Unfortunately, stack overflow suggests Xvfb wouldn't solve my problem. It apparantly doesn't support OpenGL in its goal of being of being hardware-independent.

     @hergertme Thanks! So a plain distro container?

     I'm working on installing PodMan & Toolbox now, probably will be easier once I've taken that elementary upgrade... At the same time I've got some editting work I want to clean up first...

     toolbox create --distro fedora --release f37
     toolbox enter
