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).

If anyone is interested with a working PKGBUILD; I edited my private one to work with 2020a; https://github.com/bbaserdem/Matlab/blob/master/PKGBUILD

I tried matching the dependency list with all the packages in the dockerfile. Most of the debian packages are in the arch repos; or at least AUR, but the versions referanced on the dockerfile are older than arch versions. A lot of these dependencies are probably not needed; but I don't want to test what works and what breaks one-by-one.

Still I can install just fine. Do note that matlab installer does need libselinux to run; and is needed to generate the tar.

Echoing what japm48 said, R2020a has a new installer which depends on libselinux to run. The new installer gives you the option to download files without installing which will make using this PKGBUILD slightly easier. Also, I think Mathworks changed some other stuff because, unlike previous versions, once installed I didn't have to change Matlab's glib symlinks to point to system libraries to get the add-ons manager to work.

While trying to install r2020a I had this error after executing ./install:

terminate called after throwing an instance of 'std::runtime_error'
  what():  Unable to launch the MATLABWindow application

I solved this by installing libselinux (in AUR).

For the record: I found the missing dependency by executing ./bin/glnxa64/MATLABWindow.

Besides, it works without gtk2 (perhaps it now depends on gtk3).

Just got this when trying to install

==> Making package: matlab 9.7.0.1296695-1 (Thu Mar 5 10:15:31 2020) ==> Retrieving sources... ==> ERROR: matlab.tar was not found in the build directory and is not a URL. Error downloading sources: matlab

Going to go the manual route for now

@kyak oh cool, thanks. The deps here definitely do need some work!

@greyltc thanks for the effort!

I'd like to point you to the now official Dockerfile from MathWorks themselves: https://github.com/mathworks-ref-arch/matlab-dockerfile/blob/master/Dockerfile and https://hub.docker.com/r/mathworks/matlab-deps/dockerfile.

It can be useful for us to get all the dependencies correctly.

I've just fixed a number of bugs in the PKGBUILD, so as of today with r2019b update 3, I can verify that it's up to date and working. Apologies I don't get around to updating this too often. I don't reinstall MATLAB so frequently to keep up with all the releases. If you'd like to help maintain it, let me know and I can add you as a co-maintainer. The install instructions in the wiki look mostly okay (though I haven't followed them to check that), but hopefully you should just be able to get by with reading my notes in the PKGBUILD its self.

Matlab won't install, what am I doing wrong ?

Error: This folder name is invalid. Folder names can contain alphanumeric characters and '-', '_', '.', or '/' only. The destination folder cannot be named "private".

Update, please?

The wiki is updated to solve the following error:

Using a File Installation Key requires you run the installer from a MATLAB DVD or from a directory which contains files previously downloaded via the installer.
