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).

I have updated the PKGBUILD to the latest R2022 point release. In order to comply with the Arch package guidelines, the installation directory is no more /usr/local, but /opt. This required a change in python-matlabengine, because by default the installation script looks for the MATLAB root into /usr/local, so now the MATLAB root is exported via $LD_LIBRARY_PATH (only on this occasion, it won't touch your $LD_LIBRARY_PATH).

/opt/MATLAB/R2022b has temporarily gained 777 permissions in order to install additional toolboxes. Unfortunately I am not able to do so, because during the installation I get "Something unexpected occurred". If you are able to install them, please contact me. I would like to resolve this issue once and for all.

If you have any issue, please let me know.

@telans thanks, fixed

The .desktop file should have the -desktop argument otherwise Matlab just opens a shell.

See matlab -help: "Allow the MATLAB desktop to be started by a process without a controlling terminal. This is usually a required command line argument when attempting to start MATLAB from a window manager menu or desktop icon."

@tsetsee_yugi you need to have in the PKGBUILD directory the files listed in Sources before running makepkg. If you haven't already done so, please read the installation instructions in the README.

Optional dependencies for matlab-meta cuda [installed] java-runtime: Java support [installed] zsh [installed] openal: for Orbisnap [installed] openssl-1.0: needed by MATLAB Client for MATLAB Production Server [installed] python2: needed by MATLAB Client for MATLAB Production Server ==> Making package: matlab 9.13.0.2049777-3 (Fri 23 Dec 2022 03:24:52 PM +08) ==> Retrieving sources... ==> ERROR: matlab.tar was not found in the build directory and is not a URL. error: failed to download sources for 'matlab-9.13.0.2049777-3': error: packages failed to build: matlab-9.13.0.2049777-3

If you have the error: "Unable to open this file in the current system configuration", the error can be fixed by setting aside the libfreetype.so.6 in <matlab_root>/bin/glnxa64/. You may run the following command:

cd <matlab_root>/bin/glnxa64/ mv libfreetype.so.6 libfreetype.so.6.old

Last current version (R2022b) may not work correctly, so you can use R2022a instead. Also, for issues like: "Unable to launch the MATLABWindow application. The exit code was: 127" or "symbol lookup error: /usr/lib/libharfbuzz.so.0: undefined symbol: FT_Get_Transform" , follow this: https://wiki.archlinux.org/title/MATLAB#Unable_to_launch_the_MATLABWindow_application.

If you want to know what problems gave me R2022b, other than the "classic" symbol lookup error that is fixable, it gave to me:

"$ ./matlab MATLAB is selecting SOFTWARE OPENGL rendering. [allexj@Archy bin]$ terminate called after throwing an instance of 'std::runtime_error' what(): Failed to launch web window with error: Unable to launch the MATLABWindow application. The exit code was: 1 /home/allexj/Desktop/matlab/bin/glnxa64/MathWorksProductAuthorizer.sh: line 14: 292290 Aborted (core dumped) $BINDIR/MathWorksProductAuthorizer $@"

and "$ ./glnxa64/MATLABWindow ./glnxa64/MATLABWindow: /home/allexj/Desktop/matlab/bin/glnxa64/libtiff.so.5: version `LIBTIFF_4.0' not found (required by /usr/lib/libgdk_pixbuf-2.0.so.0)"

@scondon the -r flag removes the dependencies you installed to build the package. I was talking about the -R flag, which repackages without rebuilding: if you use that flag, you don't run the installer, the $srcdir/build directory is never created, so mv can't find the FreeType files. I don't think it's a PKGBUILD issue nor a tar one, at least following the instructions on the README or running the install.sh script on a clean directory with the required files only. Other than telling you to watch what makepkg does step by step, I don't know what else to say at the moment, I'm sorry.

Maybe we can talk on a GitHub issue, so that it's public, and then we post here what we have found. I won't be able to respond instantaneously, though.

Have tried to build but am getting the same error as @wu2305 with mv: cannot stat libfreetype.so.* file. Have tried with the -r flag and without. With the -r flag, it contains bin/glnxa64/ but this directory is then empty. Is this likely a PKGBUILD issue or a mistake with the tar file?
