Arch Linux User Repository

@billypilgrim check out the archwiki page for intel related issues as well; they might relate. I don't have issues with amdgpu and this pkgbuild. Check out your card; i have AMD Radeon RX 5700 XT

Please report back if you manage to fix it; and it's fixable (a missing dependency or launch options) so I can add a fix/dependency to the pkgbuild.

Is anyone else getting issues with amdgpu?

This is what I get in my terminal when I start matlab: libGL error: MESA-LOADER: failed to open radeonsi: /usr/lib/gcc/x86_64-pc-linux-gnu/8.4.0/libstdc++.so.6: version GLIBCXX_3.4.26' not found (required by /usr/lib/libLLVM-11.so) (search paths /usr/lib/dri) libGL error: failed to load driver: radeonsi libGL error: MESA-LOADER: failed to open radeonsi: /usr/lib/gcc/x86_64-pc-linux-gnu/8.4.0/libstdc++.so.6: versionGLIBCXX_3.4.26' not found (required by /usr/lib/libLLVM-11.so) (search paths /usr/lib/dri) libGL error: failed to load driver: radeonsi libGL error: MESA-LOADER: failed to open swrast: /usr/lib/gcc/x86_64-pc-linux-gnu/8.4.0/libstdc++.so.6: version `GLIBCXX_3.4.26' not found (required by /usr/lib/libLLVM-11.so) (search paths /usr/lib/dri) libGL error: failed to load driver: swrast

And here's the error message I get within the matlab GUI once it's loaded: com.jogamp.opengl.GLException: X11GLXDrawableFactory - Could not initialize shared resources for X11GraphicsDevice[type .x11, connection :0, unitID 0, handle 0x0, owner false, ResourceToolkitLock[obj 0x643bdb87, isOwner false, <29e4dacf, 2c84828b>[count 0, qsz 0, owner <NULL>]]] at jogamp.opengl.x11.glx.X11GLXDrawableFactory$SharedResourceImplementation.createSharedResource(X11GLXDrawableFactory.java:326) at jogamp.opengl.SharedResourceRunner.run(SharedResourceRunner.java:297) at java.lang.Thread.run(Thread.java:748) Caused by: com.jogamp.opengl.GLException: AWT-EventQueue-0-SharedResourceRunner: Unable to create temp OpenGL context(1) at jogamp.opengl.x11.glx.X11GLXContext.createImpl(X11GLXContext.java:368) at jogamp.opengl.GLContextImpl.makeCurrentWithinLock(GLContextImpl.java:759) at jogamp.opengl.GLContextImpl.makeCurrent(GLContextImpl.java:642) at jogamp.opengl.GLContextImpl.makeCurrent(GLContextImpl.java:580) at jogamp.opengl.x11.glx.X11GLXDrawableFactory$SharedResourceImplementation.createSharedResource(X11GLXDrawableFactory.java:297) ... 2 more

I can still open figure windows etc. but OpenGL is disabled.

That seems to be /tmp no enough space issue, not sure if this makepkg error was also caused by that.

Read the readme.md, and use unzip -X -K to resolve libexpat issue. Rename your installer dir to something else, download to a folder called matlab and tar it there.

I managed to make it work using this. https://stackoverflow.com/a/60939113 How would I adjust this process to make use of the AUR package instead?

Edit: I have my license.lic file downloaded. Do I need any other files from somewhere before this package will work? : https://mathworks.com/licensecenter/licenses/ : I downloaded the license.lix (matlab.lic) file provided and copied to the key from the textbox into matlab.fik while downloading matlab.tar.gz from AUR and renaming to matlab.tar Now it says: ==> Starting prepare()... sed: can't read /home/USER/matlab/src/matlab/installer_input.txt: No such file or directory Where do I get installer_input.txt from?

When I download and extracted the package from the Matlab Website I get the following output:

...matlab_R2020b_glnxa64/bin/glnxa64/install_unix: error while loading shared libraries: ...matlab_R2020b_glnxa64/bin/glnxa64/libexpat.so.1: file too short

linexpat.so.1 contains : 'libexpat.so.1.6.11'

I'm getting the following error with pamac - ERROR: matlab.tar was not found in the build directory and is not a URL.

https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=matlab#n261 here's a typo, should be pacman -Q gcc8

I am using latest ucode. I reported my issue on matlab answers. Hope somebody can fix it.

I'm on a zen2 microarchitecture (AMD Ryzen 7 3700x) and it works fine. It probably is something else related specifically to your desktop. If you are not using it already; I suggest installing amd-microcode and making sure your bootloader loads the related ramdisk before loading initrd.

Either way; you can build the package on your server; copy the tar.zst file to your desktop and install using pacman -U matlab.blabla.tar.zst. For activation; after installation you can run sudo activate_matlab.sh; but you shouldn't need to if you used the licence that is appropriate for your PC (using the MAC address of any of your ethernet interfaces; as far as I recall.)

Please post this in mathworks forums; as anyone else on other linux distros having the same problem can benefit from your experience; or help diagnose what exactly is going wrong.

Strangely enough, I copied exact same files to my arch server and it runs. I guess that architecture issue still persists on this version and I'm running my desktop on AMD zen2.

I've installed the latest update and it seemed to go without any hitches apart from having to re-activate Matlab afterwards. Many thanks bbaserdem!

Everything I've tested works fine apart from Matlab's built-in updater which notifies me about an update but always fails during the installation with the message "Something unexpected occured". However I don't think the updater has ever worked for me when installing Matlab via the AUR package and it's certainly not a problem specific to this latest PKGBUILD.

I'm guessing it's some kind of permissions error but not really sure. Has anybody else managed to use it successfully?
