@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.

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 :)

remma12 commented on 2018-07-22 08:28 (UTC)

@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

zerophase commented on 2018-07-22 07:56 (UTC)

@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

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

Working on getting 4.20.0 up. I have it working, but am currently trying to figure out why fbxsdk.a gets deleted during the build process.

jrkb commented on 2018-06-07 21:53 (UTC)

When I build this, the permissions in /opt/unreal-engine are owned by root:root When opening or creating a project, I get Access errors. I of course do not use sudo when building this.

I tried creating a new group unreal, adding my user to it and run sudo chgrp unreal -Rf /opt/unreal-engine; chmod 775 -Rf /opt/unreal-engine/ But it doesn't help. When creating a project, the editor crashes and opens nautilus at the location of the project. When opening UE4Editor again and select the project I get the error that libUE4Myproject.so is not there. I had one rare moment, when everthing seemed to work and I could create a project and play around with the editor ... until I tried to add a c++ class, and I got another access error for /opt/unreal-engine/Engine/Intermediate/Build/XmlConfigCache.bin After that I was back at the libUE4MyProject.so missing. I got a hint by someone to make MyProjectEditor in the project folder, but that just crashed after an hour.

not sure how to solve this
