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).

After the system update (ArchLinux), the following error occurred while trying to open LiveScript: "The Live Editor is unable to run in the current system configuration." I have found the advice in one discussion (https://bbs.archlinux.org/viewtopic.php?pid=2028209#p2028209) - to rename file MATLABROOT/bin/glnxa64/libfreetype.so.6.

Anyone wants to take over the package? I don't use Arch anymore. Please email me so we can discuss; as I want to hand over this package to someone who knows what they are doing.

@kyak Thank you, this solved the issue. Perhaps the package maintainer should add this as a dependency as well

@kruzah install libxcrypt-compat from aur

MATLAB longer works after a soname update on libcrypt.so/libxcrypt:

/opt/tmw/MATLAB-r2020b/bin/glnxa64/MATLAB: error while loading shared libraries: libcrypt.so.1: cannot open shared object file: No such file or directory

Please note that you may need to extract/unpack the installer with unzip instead of some GUI utilities (e.g. Ark), or some symbol links or so would be missing, and you will get such error messages when running ./install:

/tmp/matlab-instlaller/bin/glnxa64/MathWorksProductInstaller: error while loading shared libraries: /tmp/matlab-instlaller/bin/glnxa64/libicudata.so.69: file too short

I followed the instruction in https://github.com/Victrid/matlab-aur, everything went find until the "makepkg -s". When I executed this command, It always stop at

Starting build()... ERROR: A failure occured in build(). Aborting...

Any suggestions? (fyi, my source is matlab 2020b)

@tornado99 what type of instructions do you want? If you don't want to compile gcc8 on every machine, just compile it once and then install it on all the machines. If you want to run MATLAB without a compiler, just remove gcc8 as a dependency.

There should be clear instructions for those who want to disable GCC from the pkgbuild. I just install Matlab from their installer on most of my machines as I can't afford to lock up a machine for 1/2 a day compiling GCC. In fact if you wanted to run MATLAB on a low-end machine you could be waiting several days for the GCC part to finish.

@bbaserdem ./install from r2021b iso works fine for me
