@rellieberman the MATLAB installer will not care, but you will likely run into problems with pacman if you either try and reinstall the current version or upgrade the package to a new version.

Hi all, and thanks for all the amazing work! I have a question, if I want to add more packages after a partial install, do I have to redo the whole installation? is there a way to just add the new packages I need? Thanks

Thanks for all the great work! Sadly I am stuck with the same log as this comment. I have downloaded the latest PKGBUILD 'pkgrel=5', 'pkgver=9.12.0.1903524' and Matlab <version>9.12.0.1927505</version> which sets pkgrel and pkgver correctly. Still building gets stuck at the non-existent folder ${srcdir}/build/extern/engines/python. Do you have any guidance for me?

Thanks for the update, partial install works now.

@sukanka thank you, I left a comment on your pull request and I have enabled the Issues tab. I don't know why it was disabled.

@Rubo, I ran namcap for the built package to check dependencies, and here is the output. https://fars.ee/53NB

Dependencies should be updated according to the output. Some are in depends and some should go into optdepends (for example java-runtime) and some should be removed(libselinux)

BTW, I cannot open an issue in that github repo.

@sukanka I'm glad to hear you built it successfully. As mentioned in this comment, there is a repo here. I guess the choice of links being grey near black text is a little unfortunate...

@Rubo, thanks for your reply, I now use the latest PKGBUILD, still, the problem is

==> Starting pkgver()...
==> Removing existing $pkgdir/ directory...
==> Starting build()...
  -> Running original installer...
  -> Building Python API...
/home/sukanka/Downloads/matlab/PKGBUILD: line 160: cd: /tmp/makepkg/matlab/src/build/extern/engines/python: No such file or directory
==> ERROR: A failure occurred in build().
    Aborting...

But I notice another thing that may help. My matlab version is different from yours.

<version>9.12.0.1884302</version>
<release>R2022a</release>

I'm now redownloading 9.12.0.1927505 Update: I build this version successfully.

BTW, maybe you can setup a github repo for discussing this problem.

@sukanka sure, I re-package it every time I edit the PKGBUILD, to see if it works, and the current one works following the standard procedure, with or without the install.sh script. Maybe you meant /tmp/makepkg/matlab/src/build/extern/, since the problematic directory is ${srcdir}/build/extern/engines/python?

I bumped the release of the PKGBUILD to 4. Nothing has changed since the previous one, just pkgrel, please update it so that we are all on the same track.

With the Python MATLAB engine, it seems to me two problems can occur:

1. Right after -> Building Python API.... If you are doing a partial installation, when the MATLAB off-line installer is ran at line 156, ${srcdir}/build is empty, so surely ${srcdir}/build/extern/engines/python can't be there! I'm thinking of splitting the building and the packaging of the Python engine from MATLAB itself. Please, let me know what do you think.
2. Right after -> Packaging Python API.... If you are using an old PKGBUILD, where you have pkgname=('python-matlabengine' 'matlab') instead of pkgname=('matlab' 'python-matlabengine'), the package_python-matlabengine function is ran after package_matlab. As you can see at line 274 of the current PKGBUILD, package_matlab moves ${srcdir}/build into ${pkgdir}/${instdir}. Then, at line 192, package_python-matlabengine changes the current directory to ${srcdir}/build/extern/engines/python, and an error is thrown, because ${srcdir}/build isn't there anymore, now it's in ${pkgdir}/${instdir}! That was a problem in one of the previous PKGBUILDs, which I fixed, and that's why I added the comment at lines 5-6.

I hope those are the only two problems, but please let me know if that's not the case.

@Rubo, did you build the package yourself? Could you please have a look at the downloaded files? I notice in /tmp/makepkg/matlab/src/matlab/extern/, there is only include/, no engines/python. I used the latest PKGBUILD, and matlab R2022a downloaded from matlab installer.
