Arch Linux User Repository

@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.

post the issue to Epic

seems windows is prioritized platform for them, so meh...

Post a fuller log as well

3k lines of logs ;)

engine crashes 1-4 times at day, regularly, for random reason, and last few lines always looks like this (and I guessing the wrong path causing a problem)

i get

ERROR: Repository not found. fatal: Could not read from remote repository.

Since version 4.20 I get a compilation error :

(I'm not on Arch anymore, but I still use the AUR for some packages) I don't know if others are affected but I've made a small patch around it so the redefinition overwrites the previous one seamlessly.

@ruestique I would try recompiling the engine with the cache cleared. Post a fuller log as well. Other than that with there being so much hardware variability between users I would post the issue to Epic.

Hi!

I noticed too much instability, 3-5 crashes per day, after I looked at the crash report, I saw that:

blah-blah-blah [File:/home/username/.cache/pikaur/build/unreal-engine/src/UnrealEngine/Engine/Source/Runtime/Renderer/Private/RendererScene.cpp] [Line: 849]

Does this path cause a problem or not? Cache folder I have already cleared.

@remma12 @zerophase Thanks for the tips it worked :)

@wolfyrion it's hardcoded at the top of the Makefile, need to change UNREALROOTPATH = /tmp/makepkg/unreal-engine/src/UnrealEngine to wherever you are installing from This will change the SHA hash of the makefile so you'll need to change the pkgbuld too edit line 44 from 'f07f66c6784c82b3629bfad5a2c01515e012d5feec08f63dcf15c2c06cc8b62e' to 'SKIP'

Save and make the package - it's compiling now for me

@wolfyrion oh I hard-coded the package build for my system. You can manually modify the patch for your directory with vim or nano. Replace "/tmp/makepkg/" with where ever you're installing from. I think it's one of the patches at the top of prepare. I won't be able to fix the issue till tomorrow as it's late, and I need sleep.

Hi, I am getting this error

Register the engine installation... bash "/tmp/makepkg/unreal-engine/src/UnrealEngine/Engine/Build/BatchFiles/Linux/Build.sh" UnrealVersionSelector Linux Shipping

Think I fixed the issue. Just had to add staticlibs to the options array. Will upload in an hour.
