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).

@streckus: very nice, thank you! It would also be nice if the PKGBUILD would check the exit code of the matlab installer for failure because if the matlab installer fails you won't know, it will only show:

install: cannot stat '/home/MyName/.cache/pacaur/matlab/pkg/matlab/opt/tmw/matlab/license_agreement.txt': No such file or directory

The error, that @yiping_huang, @xcabal and I experienced. For me it failed because I entered a wrong installation key.

What are the steps to install Matlab using this PKGBUILD? Wiki tells about an ISO, but MathWorks lets download a ZIP, and the PKGBUILD uses a TAR. Any example how to proeed?

Why is there added the weird number after version 9.3 (aka current version 9.3.0.713579)? As far as I know, it's not MathWorks' numbering (they use just 9.3) and when I tweaked the PKGBUILD manually from previous release before you bumped the version up to comply with our school's installation of MATLAB, I just put there 9.3 and now pacaur (pacman helper) wants me to update it every time, since 9.3.0.713579 is newer version than 9.3. I know, I can add it to IgnorePkg (and that's the current status), but it's sort of annoying. Anyway, not to sound so negative, thanks for the PKGBUILD, it's awesome to have something to build it upon ;)

I modified the PKGBUILD to correctly link to gcc49 (for mex), link mex as /usr/bin/matlab-mex for avoiding conflicts with texlive etc. and include the fixes for Addon Manager and Help Browser from the Wiki mentioned in Turtizzles comment below. You can find my version here: https://pastebin.com/wyKwL728 (Also, I dropped the ncurses5-compat-libs dependency since its not needed anymore, see https://wiki.archlinux.org/index.php/matlab#Installing_from_the_MATLAB_installation_software )

gcc5 was updated to version 5.5, now the path to libgfortran.so.3 changed to /usr/lib/gcc/x86_64-pc-linux-gnu/5.5.0/libgfortran.so.3. The last line in package() needs a change. :) For everyone who does not want to build the entire package again because of this small change: Open /opt/tmv/matlab/bin/matlab in the editor of your choice and change the two paths manually. Edit: As we're already editing links: we could also include the fixes from "Addon Manager not working": https://wiki.archlinux.org/index.php/matlab#Addon_manager_not_working (In addition to the update, ofc)

@21violins you need to download the software from the Mathworks and put the software in the build directory. the PKGBUILD tells you how to do this.

@Turtizzle the Arch packaging guidelines (https://wiki.archlinux.org/index.php/Arch_packaging_standards) say "Packages should never be installed to /usr/local". I think the best thing to do is probably just create a link in /usr/bin called matlab-mex instead of just mex. If that causes problems for users, then they can add /opt/tmw/matlab/bin to their path variable.
