Plotting doesn't work: GLException: Not a GL2 implementation #8

Closed wjt closed 1 year ago

wjt commented 1 year ago

An Endless OS user reported that Scilab no longer displays plots. Apparently this previously worked and now does not.

I can reproduce this. I see the following exception in the console:

I tested the previous build as of 131f5f36, same issue. I also tested on an X11 session, same issue. My final guess is that the user was previously using an older version of Endless OS with an older Mesa, but I haven't tested this further.

I can also reproduce this on a Fedora 37 machine. It is not Endless OS specific. Both machines are Dell XPS laptops with Intel integrated graphics (one from 2015, one from 2019). I do not know the original reporter's hardware information.

The issue above seems to be a known issue upstream:

Forcing software rendering by setting LIBGL_ALWAYS_SOFTWARE=1 in the environment is a somewhat nasty workaround but it would at least make the app usable.

Another (better but more involved) approach would be to remove the dependency on GL2.

I know very little about Java or GL but some Googling suggests that you can explicitly request a GL2 context:

https://forum.jogamp.org/Not-a-GL2-implementation-exception-td4030873.html suggests that apps should switch from big-GL to GLES2

kevinsmia1939 commented 1 year ago

Does non flatpak scilab work?

wjt commented 1 year ago

Fedora doesn't package it. Endless OS is an immutable system.

I tried installing the scilab package from Debian Bullseye in a toolbx and plotting fails with a different but somewhat similar exception:

Maybe try the executable from here: https://www.scilab.org/download/scilab-6.1.1

If it does not work it probably an issue with Scilab. But maybe we can turn on LIBGL_ALWAYS_SOFTWARE=1 by default to work around it until it is fix?

wjt commented 1 year ago 
scilab-bin: error while loading shared libraries: libtinfo.so.5: cannot open shared object file: No such file or directory

I'm afraid I can't spend any more time on this. I'm not a Scilab user, I'm passing on this problem on behalf of a user of our distro.

davidcl commented 1 year ago

could you try overriding MESA GL version using: export MESA_GL_VERSION_OVERRIDE=2.1 before launching Scilab ?

wjt commented 1 year ago

Thanks @davidcl, I opened #10 for that change.
