Arch Linux User Repository

TODO:

1. Figure out the users and permissions. Currently, /opt/MATLAB/${_release} has 777 permissions, which is obviously undesired. It might be better to create a user group and require users to manually add themselves to it for security reasons.

2. Improve the installer. For example, the current inotify watcher spams stdout and does not account for the end of the download/installation or the width of the terminal, which results in flaky output.

3. Figure out the dependencies. The list of Debian/RHEL dependencies is public, but it includes some seemingly unneeded packages. This might be because they are required by dependent products/add-ons. Additionally, the current logic for removing bundled dependencies should probably be rewritten. Maintaining an exhaustive list for a single release is very difficult, and these components change without notice. Moreover, the current approach may go against the Arch KISS philosophy. Ideally, we should remove only the problematic components like Qt, XCB, libtiff, gcc-libs, fontconfig, etc.

4. Add auto-discovery for packages written for MATLAB. My plan was to use /usr/lib/MATLAB/${_release} for release-specific modules and /usr/lib/MATLAB/common for shared (mostly architecture-independent) packages. However, load order matters, and "common" modules need to specify which releases they are compatible with. This means we need to implement our own logic for discovering and loading these, likely via hooks, shell scripts, and configuration files (perhaps TOML could work?).

5. Fix the Python components. python-matlabengine does install the Python components built against the version of Python shipped by Arch. However, some proprietary CPython components are not included and are built against ancient Python versions. This likely requires version spoofing or some alternative approach.

6. Write and upload packages for previous MATLAB releases. It is entirely possible to have multiple releases installed simultaneously. I have a few of these packages myself, but they are drafts and not suitable for upload to the AUR.

7. Write and upload packages for MATLAB-dependent add-ons and products. When installing MATLAB required user intervention for source access, it was acceptable to break reproducibility and manually specify required products for installation. Now that we use MPM, it would be better to separate products into individual packages. These packages would install themselves and their dependencies into a specific location, then use appdata to install only the component's files. The problem is that MATLAB often includes conflicting files that need to be combined or overwritten. Obviously, we can't allow that, so a hook must be implemented to, for example, combine *.combine@matlab-simulink and replace *.replace@matlab-documentation files with backups. Needless to say, this is challenging to implement, so the previous approach (having users specify the product list) might still be preferred.

8. Write and upload the matlab-runtime package. I have a draft, but the problem with this package is that it installs the runtime for every available product. Ideally, for source-built packages, we would want to makedepend on matlab-$product and depend on matlab-$product-runtime. However, this is not possible without splitting the runtime packages, which poses the challenges described above. I’ll try my best to revisit this sometime later.

@aoneko, @Reexys, please read the post-installation instructions. If you've lost them, you can find the same information here.

@jadesoturi The .zip you download from tmw only contains the files needed to run the installer, not all the files required for installation. You need the complete iso. Alternatively, you can run the installer manually, it will download the proper contents of the archives/ folder to a folder in /tmp/. You can then use those files along with the contents of the .zip you previously downloaded to generate the matlab.tar that this package needs to build.

I'm having issues installing this. I got the fik and lic files and the latest zip from Mathworks, but when running makepkg -si it terminates with the following error:

  -> Modifying the installer settings

@hottea, thats great info. I am not, I am just creating a local tarball of matlab, so I can distribute it easily on my 4 archlinux installations. But knowing the file structure for the tarball is a godsent.

On further inspection, matlab now (since 2018b at least from what I have noticed) installs the products to /tmp/tmw<random> while using the network installer. I don't think this was the previous behavior (and it is bad practice to put 8GB on a tmpfs) do notice that the file is deleted upon installation/exiting; so pause once the installer reports 'installing' and cp the directory out of tmp.</random>

@bbaserdem Hey, if you're license administrator, you could download the product via installer with download only option, see here for detail. A typical matlab tarball look like this:

matlab
├── activate.ini
├── archives/
├── bin/
├── etc/
├── help/
├── install
├── installer_input.txt
├── install_guide.pdf
├── java/
├── license_agreement.txt
├── licenses/
├── patents.txt
├── readme.txt
├── sys/
├── trademarks.txt
├── ui/
└── version.txt

Matlab products locate in archives directory.

I was wondering if anyone had any issues installing R2018b. I'm trying to create the tar file using the installer, but it looks like the toolboxes are installed somewhere i dont know. I used to install to a directory called faux, and cancelled the moment toolboxes finished, then merged the two directories. (Not working this time around, Im getting missisng file warnings on the installer)

I tried looking for guides regarding creating the tar but nada. Can anyone help out? (And maybe we can include instructions in PKGBUILD how to properly create tar from the installer?)

@petronny If gcc6 is not listed as dep, then we should not modify mex opts in ${MATLAB}/bin/glnxa64/mexopts/LANG_glnxa64.xml. And gcc6 in AUR is gcc 6.4, not gcc 6.3 which is officially supported by MathWorks.

@petronny matlab.lic is available in your account center in MathWorks website. If you don't have one, then you could/should not install matlab.

1

For non-network installations, installation from a purchased DVD for example, nowhere will provide this matlab.lic file to users.

Current PKGBUILD requires that users have to run touch matlab.lic to generate a meaningless file before running makepkg.

2

Okay, there are 2 solutions,

1. you could keep them and set gcc6 as a optional dependency.
2. you could remove them and set gcc6 as a dependency.

Now gcc6 is removed from the official repositories.
It makes the current way, which is the solution 1, is acceptable now. So you can keep them.

3

Yes, you should set mex options by the way suggested by the wiki pages.
