@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:

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.

For some reason, all of my shortcuts are messed up. When I right-click on an unreal project to generate project files it thinks all of the apps are in my Yay cache folder

@mordzerat, I'm a member of the UE org and can't access 'your' link simply being logged into the site (where anyone logged in as member of the UE org can view the -actual- Unreal repo). Until Epic -themselves- tells There's no need for a fork mirror anyway, it's no different than simply using the original repo and using CDNs. Your post reeks of an attempt at a supply-chain attack. You're also wrong about the source no longer being at It is there and it is the only official repo. Not to mention EpicGames-Mirror-A's account/org profile looks like a phish copy. Maybe they just lazily set it up, I don't know, it just reeks and no random post is going to convince any sensible person to swap random repo sources like that.

@mordzerat Nonsense, the source is still where it was before and it clones just fine; I'm cloning the repo just fine without issue. Don't confuse people with fishy repo links like that when there's nothing actually wrong with the official repo.

Unreal source on git is no longer , it is now forked via mirrors as an example .

Since it's private, it needs

gh auth login
to access the repositories.

git ls-remote https://<user name>:<token><repo owner>/<repo name>.git

in case of the mirror it would be

git ls-remote https://<user name>:<token>

@rabcor, Ryzen Threadripper here, 20-40 minutes for me with plugins, excluding download-times. (4x2TB NVMe RAID0, 64GB RAM, cache, etc...)

This takes hours to compile on a ryzen 9, what ever happened to 40 minutes on an old shitty AMD FX processor? lol.

I'm not particularly familiar with Unreal's source beyond its packaging (I don't personally use it much) and I'm not personally a C/C++ developer.

That said, I can't assist you with that issue / explain why it is but if someone else here can they're free to do so. I recommend though that you thoroughly report this over on Epic's official support forum and someone more familiar might be able to assist you. No promises though.

I install 5.4.1, I run the start button, but cannot stop. error msg:

@Neko-san I tried looking around in the source files but couldn't find the issue. I think they might've just broke something in the build-system, or maybe something's wrong w/ my setup as I normally use unreal-engine-bin. For the time being, I'll just be returning to that.

@coolitic Try seeing if you can find where that log it's talking about might be in the src folder; I can't diagnose this from my end right now because of an issue with my ISP (I'm on my phone right now) but I'm trying to follow how the hell the built tool is failing there...

It clearly is still a valid option because it does start the Linux phase but then fails with hardly an explaination as to how, from what I'm seeing.

(Would be fantastic if Epic actually wrote meaningful error messages! Everything after that part is essentially gibberish because the build steps haven't changed since 5.0 so there shouldn't be a complaint about the SDK nor about missing files. Well, assuming the Linux build system itself isn't broken or the build steps changed without notification, anyway. :D)
