Matlab 18a and 18b Fail to launch on Fedora 35

Hi,

I'm having difficulty launching Matlab 18a and 18b on Fedora 35. I have tried these solutions without success:

• https://www.mathworks.com/matlabcentral/answers/98599-why-will-matlab-not-start-up-properly-on-my-linux-or-unix-based-system
• https://www.mathworks.com/matlabcentral/answers/456839-fedora-30-matlab-start-issue
• https://www.mathworks.com/matlabcentral/answers/364727-why-does-matlab-crash-on-linux-fedora-26-with-a-segmentation-violation-r2017b-or-later
• https://www.mathworks.com/matlabcentral/answers/399207-matlab-does-not-start-on-fedora-28#answer_321678

When I launch Matlab 18a (from the command line), I get this message on the command line:

MATLAB is slecting SOFTWARE OPENGL rendering.

and that's all. No GUI appears, and it does not return me to the command line. Control-C does nothing, and the only way to kill whatever is happening is to close the terminal window.

When I launch Matlab 18b from the command line, I ge the same message on the command line, and the splash screen appears, and then nothing.

I cannot find any MATLAB logs in my home directory. Is there some other place I can look?

If I use the -nodesktop command-line option, I get

[chris@fedora ~]$ /usr/local/MATLAB/R2018a/bin/matlab -nodesktop
MATLAB is selecting SOFTWARE OPENGL rendering.

According https://www.mathworks.com/matlabcentral/answers/98599-why-will-matlab-not-start-up-properly-on-my-linux-or-unix-based-system, this indicates a Java problem, but I cannot diagnose it without any other information.

Oddly, this problem does not occur on these releases of Matlab:

• 15a
• 16a
• 16b
• 17a
• 17b
• 19a
• 19b
• 20a
• 20b
• 21a
• 21b

Can anybody help me diagnose this? I need to resolve this to support some automated regression tests I am running for a commercial product.

Thanks,

Chris

My new hero is Jaineel Nandu with Mathworks. He or she (apologies) provided the solution:

The key was:

sudo yum install libnsl

along with the suggestions in https://www.mathworks.com/support/requirements/previous-releases.html.
