@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).

@AverytheFurry you Might need to change permissions. There might be a directory not getting set correctly. I think it's chmod -R 770 you want.

If you're upping the processor multiplier, and have more than 30 logical cores, (hyper threading, etc) you need to edit BuildConfiguration.xml MaxProccessorCount to be greater than or equal to LogicalCores * MaxProcessorCount. Should speed compilation up for most. Need to turn the patch on in the PKGBUILD.

A multiplier of 1.5 might make the computer unresponsive for other uses. Probably depends on processor.

If anyone has more than 30 logical cores let me know, and I can update the default. There's an upper limit in terms of memory and how many files your system can have open at once. At a certain point compilation probably takes longer.

@AverytheFurry this is because by default in this AUR, Generate project files has not been done for IDEs. you can cd into opt/unreal-engine and ./GenerateProjectFiles.sh -VSCode you can add more flags according to your IDE preference. To generate it for all supported IDEs its simply - ./GenerateProjectFiles.sh

The issue mentioned previously seems to only happen on c++ projects

I am getting the following: ERROR: Unhandled exception: System.UnauthorizedAccessException: Access to the path "/opt/unreal-engine/.vscode" is denied

This file does not exist.

@zerophase I already have, that's not the issue here; this isn't my first time compiling the engine.

@neko-san sign up for an Epic Games and Github account.

It failed to build for me during the mono dependencies collection stage?

If you want to use the system mono set the environment variable to UE_USE_SYSTEM_MONO=1. You can also turn on the features while building the package through the system build.

@neko-san I believe you need to set fish as an interactive shell, and set environment variables in bash or some other scripting language.
