Matlab 2025b does not start, Segmentation violation

othersamo_ · 2026-02-08 16:09:57

hello,
I am trying to start matlab 2025b on my system. I already have a running version of 2024b. Fix for that is documented here: https://bbs.archlinux.org/viewtopic.php?id=308046

I would like to update to 2025b, if possible. The original tricks with changing gnutls no longer seem to work and the same:

MATLAB is exiting because of fatal error
Fatal Error:
Throw location unknown (consider using BOOST_THROW_EXCEPTION)
Dynamic exception type: mwboost::wrapexcept<std::runtime_error>
std::exception::what: Transport stopped.

Running patchelf and execstack does not resolve the issue anymore.

Did anyone manage to get the new matlab version up and running. What steps changed since the 2024b version?

I am installing it viia the MPM (matlab package manager). maybe that's the root cause of the issue?
Thank you

Do you run into this w/ the older gnutls and the normal or lts kernel?

othersamo_ · 2026-02-09 10:28:43

Yes, what I do is that I install matlab and change gnutls to the older vrsion. Different kernels have no effect.

Mod note: moving to AUR Issues

Hi everyone. I wonder if anybody got any progress on this. I tried with R2025a and R2025b and I always get a segfault identical to the one of the OP.

The patchelf/execstack trick does not seem to work anymore, unfortunately.

So this is not https://aur.archlinux.org/packages/matlab ?

zoidx86 · Today 13:02:40

In my case, it is manual installation via mpm, using this template file. The AUR package gets stuck at the gnutls3.8.9 build, actually (might be my fault, I did not investigate a lot).

Still, I prefer the manual installation for different reasons. Sometimes I need multiple MATLAB versions installed alongside each other, for example.

I tried the approach that allowed me to install the 2025b version back in January in another Arch install, on my laptop:

- downloaded gnutls3.8.9 into and symlinked the contents of gnutls3.8.9/usr/lib/ into /bin/glnxa64
- ran /bin/glnxa64/MathWorksProductAuthorizer and installed the license
- tried to launch /bin/matlab

I also tried to remove the symlinks before running MATLAB, but to no avail (same exact segfault). The version on my laptop instead is still running fine (probably because the license installation was finalized before some update broke the process?).

Thanks for all the help!

"Stuck" how? Does it fail? Do you get any errors? Can you still build https://aur.archlinux.org/packages/gnutls3.8.9 separately (using makepkg, no aur helpers)?
Since this is where the error occurs it's likely a critical problem.

Arch Linux
