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).

@VictriD; what you have is amazing; i do want to add it to the script.

@all; i can't make matlab installer (2021b) run on my PC; does anyone have any issues with it?

Hello, I've modified the package script from burger's https://github.com/bloatmode/matlab-aur.git. The new script can be located by https://github.com/Victrid/matlab-aur.

This script can:

• Determine and update the versions by the provided matlab installer package, and determine the needed dependencies' version.
• Marked GCC stuff as optional dependencies. These are only used by compiler related programs.
• Removed the license file, then the package can be distributed through network and multiusers on a machine. As matlab is licensed per-user, this can be more practical as users will activate the matlab when they opened for the first time.

Meanwhile:

• The script installs matlab into /usr/lib rather than /opt
• The script do not allow multiple instances of versions.

Should opt/tmw/MATLAB-rxxxxx be given user read/write access? Otherwise toolboxes cannot be installed using the Add-on Explorer.

Edit: This bug actually now occurs as soon as matlab has started

I have discovered a bug using kernel:5.10.16-arch1-1 where when I click on a different window then come back to matlab I cannot click anywhere, I can minimize, expand/restore and close but I can't click on anything else. Restarting the app allows me to use it again however clicking out of it again replicates the bug. Let me know what further details you would need

You can get gcc8 binaries by adding the arch4edu repository.

gcc8 is required to compile mex files using native gcc. This is not a minimal package; if you don't want gcc integration, you can install matlab through other methods.

I ran this on an i7 desktop with 16GB RAM and it choked the machine trying to compile gcc8 for over an hour, but it did complete successfully. I then tried on a lower spec laptop and it aborted with gcc compile errors after about 20 minutes. Could you say what are the advantages of using gcc8? and if this could be made optional as otherwise users with lower spec machines could be waiting many hours just to get Matlab installed.

I was able to overcome the "Error Starting Desktop" by installing both jre8-openjdk and jdk8-openjdk and running export MATLAB_JAVA=/usr/lib/jvm/java-8-openjdk/jre in the terminal, however I am experiencing some internal errors which are due to my integrated intel graphics. I will edit this comment once I resolve these issues, and what I did.

UPDATE: This didnt take long... I am able to start matlab with zero problems now provided I use the -softwareopengl flag when running matlab. Please note that I can reproduce the error by not including the flag - I will add this as an alias so I dont need to type it every time.
