@juancarlospaco this is easily done on your own system, not in a PKGBUILD, given that building packages runs as root:

sudo groupadd unrealengine-users
sudo usermod -aG unrealengine-users (your-username)
sudo chown -R root:unrealengine-users /opt/unreal-engine
sudo chmod -R 775 /opt/unreal-engine

Permission issues like this are already mentioned on the UE Arch wiki page: https://wiki.archlinux.org/title/Unreal_Engine_4#Installing_from_the_AUR

This is a user system problem; I already did what I could without needing users to do the above by giving the 777 permissions. If it still gives you trouble, you'll have to use the example to solve it or change the install location to somewhere you have user permissions by default (as I cannot do this for you).

Will update to 5.0 when it is released.

No, it doesn't. ${_install_dir} is a relative path and I only ever call it when touching things inside of ${pkgdir} for packaging; now, ${pkgdir} IS an absolute path, but I don't define that, makepkg does.

That being said, the only way that can go wrong is if your system somehow misinterprets what ${pkgdir} means. That's completely out of my hands.

Additionally, you might have your drive mounted via your desktop environment instead of /etc/fstab; in which case, I advise you mount with fstab instead to minimize other potential interferences on your system. That said, I'm not responsible for the reason why.

I have not only rebooted my system plenty of times, I've also run this script from a fresh-clone. If it helps at all, that path is for my external drive, which shouldn't have any problems as I store all my AUR packages on an external drive.

I'm not well-versed in creating AUR packages, but is it possible that ${_install_dir} is utilizing an absolute path?

Neko-san commented on 2022-11-22 00:28 (UTC)

Then point out where in the script and prove it, because I've been over this thing over 17 times

coolitic commented on 2022-11-22 00:26 (UTC)

That path is simply the absolute path, since my package is in /run/media/username/SE800/sources/aur/unreal-engine/. Meaning somewhere in the script, an absolute path is being used, which is obviously incorrect.

I've made changes to it now to use more explicit paths and to use find to look xbuild and mcs now

As for this: /run/media/username/SE800/sources/aur/unreal-engine/pkg/unreal-engine/opt/unreal-engine/run/media/username/SE800/sources/aur/unreal-engine/src/unreal-engine/

This path isn't represented in the bash code at all; I advise that you reboot your system

coolitic commented on 2022-11-21 23:36 (UTC) (edited on 2022-11-21 23:46 (UTC) by coolitic)

Similar thing happened: chmod: cannot access '/run/media/username/SE800/sources/aur/unreal-engine/pkg/unreal-engine/opt/unreal-engine/Engine/Binaries/ThirdParty/Mono/Linux/bin/xbuild': No such file or directory

And again, this is a folder path that should not exist and is where all the files are going: /run/media/username/SE800/sources/aur/unreal-engine/pkg/unreal-engine/opt/unreal-engine/run/media/username/SE800/sources/aur/unreal-engine/src/unreal-engine/

Paths are being set incorrectly somewhere. Also, next to the run folder under pkg/unreal-engine/opt/unreal-engine/ is an Engine folder, if that helps.

One thing that's annoying is that if something fails in package() and you run makepkg again, you have to rebuild everything from scratch (one could just move files back manually, but that's not ideal). Perhaps it would be a good idea to have moving the build files as the last thing that package() does? That way, if anything else fails, we won't lose precious build files and have to recompile.

Fixed

Getting the following error:

install: cannot stat 'GenerateProjectFiles.sh': No such file or directory
==> ERROR: A failure occurred in package().
    Aborting...
 -> error making: unreal-engine

@cooltic I did make a slight mistake with something in the .sh bash script but that should(?) be unrelated to the issue you're having

I'm about to update that in a minute, but that script is supposed to be edited towards the end of package() function in the PKGBUILD, so if you're still trying to avoid a rebuild, that's the reason why it's probably not picking out a correct location
