Arch Linux User Repository

Hi, I'm tackling the problem with the add-ons installation, where the installer can't write to /usr/local/MATLAB/R2022b. I think we should avoid manual chmods or chowns, as it would be easy to mess up with the permissions, so I created a matlab group with rwx permissions, which owns the tree starting at /usr/local/MATLAB/R2022b. The PKGBUILD sets up the correct permissions, so after installing MATLAB, you should just add yourself to that group, re-login and then you should be able to install add-ons. So far I'm able to start the installer, download the add-on archive, but when I get to Performing post-installation tasks. This may take a few minutes..., an error occurs, and the installer logs End - Unsuccessful Exception: java.lang.InterruptedException without further information.

If anyone wants to help me resolve this issue, here is the repo: https://github.com/Rubo3/matlab-aur/tree/addons.

I updated the PKGBUILD to MATLAB R2022b. Sorry it took so long. Here are the main changes:

• The dependencies have been updated according to namcap (thanks @sukanka), and are now managed via the matlab-meta meta package, now it's really easy to play around with them, as you don't have to rebuild the entire MATLAB package (thanks @bbaserdem). I still don't know the exact dependencies needed by MATLAB, as I don't use all its toolkits and whatnots. As always, please tell me if you find something.
• The MATLAB installer now outputs its logs in install.log, under the same directory of the PKGBUILD, so that you can check whether something went wrong even if it didn't fail (e.g. when you need a new license or installation key because the major version changed).
• I moved python-matlabengine to its own repo, which is built from upstream and works for the latest MATLAB versions. Currently it supports Python 3.9 and 3.10. If you have other needs, you can find the installation instructions here. Since the source files are still provided in your local MATLAB installation under $_instdir/extern/engines/python, building it and packaging it here was really just a convenience. I would like to know how many users of this PKGBUILD really need to spoof their Python version, so that we can reason about putting back that extra logic in the other PKGBUILD.
• I also removed the Mesa workaround and the optional compilers, are they still needed?

READ THE README FILE IN THE REPO. NO AUR HELPERS SUPPORTED. ONLY ARCHLINUX AS OS IS SUPPORTED. YOU SHOULD BE BUILDING THIS PACKAGE USING MAKEPKG, NOTHING ELSE WILL BE SUPPORTED. Please only post issues here AFTER you followed the README.md. located at the root of this repo: https://aur.archlinux.org/cgit/aur.git/tree/README.md?h=matlab Due to a lot of comments; my spam filter is removing AUR notifications which keeps me from responding timely to issues in packaging, please don't post if you don't do some troubleshooting yourself. If your skill level is not up to troubleshooting (or following simple instructions as laid out by the readme), just install matlab locally, without using this package.

• This PKGBUILD is NOT a minimal installation; as it has (hard) dependencies to gcc8 to force MATLAB to use system libraries. While generally not required; this PKGBUILD is trying to make MATLAB work with the system rather than with the mathworks-provided binaries. Currently it also does the python integration so that jupyter can be used with it.
• This will only work with 2020b version; and will not work with earlier (or later) versions.
• This PKGBUILD DOES NOT DOWNLOAD MATLAB FOR YOU. The EULA prevents redistribution of the software. Read the README.md file contained in the PKGBUILD repo. This is essentially a script to integrate an existing matlab installer with your archlinux system; it does NOT come with any software from Mathworks. You most likely cannot build this package using an AUR helper; you NEED to manually provide files; and to get the files you need a valid MATLAB licence. The process of fetching the files is described in detail in the README.md in the repo. (You can use any valid credentials to install the package using this PKGBUILD; including a licence file that does not match the machine; but you will need to reactivate matlab by using activate_matlab.sh with root privileges.)
• Current users; please help me test and trim the dependencies list, and submit your personal fixes for issues if you have them so they can be added to the PKGBUILD. (Cuda related contributions; if needed would be good as I don't have nvidia GPU's to test compatibility.)
• To use jupyter with matlab; you also need jupyter-matlab_kernel(-git).

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?

I would check mathworks forums for a fix; as if the provided installer is not working on your system it's an issue on the installer end. I can't replicate your issue so I don't know how to help you.

If you find the solution please post it here.

Seems to be a matlab installer issue. Cannot install even with their default installer. Generate a "archive is not a ZIP archive" error but last one has this issue is way back to 2016a. No idea what's going wrong there.
