@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.

@Premik, That memalloc issue might be relating to a memory leak or something. I've got an associate who ran UE5 on Linux with a 2 GB card just fine enough to build a simple Hello World. To limit memory for compilation, limit cores. The dotnet stuff is spot on, though. I've spent an entire three days updating my (cloned) projects from UE4 including plugins...disastrous setback for so long.

Was trying to build via the UAT with Android support: -set:WithAndroid=true. But I was getting some command-not-found error at the very end. While the command name in the error message was actually blank. So I ended using GenerateProjectFiles and make.

UE5 shifts old dotnet which doesn't recognize system certs on linux. More recent dotnet works fine. But the system_mono flag didn't work for me and the UAT still used the embedded one. So another workaround for the NuGet ssl errors would be to import the root anchors into the CurrentUser user storage:

 dotnet tool install --global dotnet-certificate-tool #Install 3rd party tool to import .Net certs
 trust extract --format=pem-directory --filter=ca-anchors /tmp/certs # Export anchors
 ls /tmp/certs/*.pem | xargs -n1 certificate-tool add --store-location CurrentUser --store-name Root  --cert #Import to local store 
 # New files should show up in the ~/.dotnet/corefx/cryptography/x509stores/root

At some stage the compilation really took nearly 32G memory. Triggering oom killer.

At the end I found out my rusty GPU with only 2G of ram is not enough to run UE5. Keeps crashing on GPU memory allocation errors. Was ok on UE4 but UE5 only supports Vulkan.

This package can now be adopted.

I had success building and running Neko-san version, but there are several issues with build:

  • ICU is not found -> install libicu50, it may be the candidate to makedeps (you can use DOTNET_SYSTEM_GLOBALIZATION_INVARIANT=1, but you will have to use it every time you run Engine)

  • nuget SSL connection may need you to make soft links (Arch and Manjaro solution from Nuget Github): ln -s /etc/ssl /usr/lib/ssl ln -s /etc/ssl /usr/lib64/ssl

  • Project build needs write permission to /opt... I just opted out to build with makepkg and unpack Engine to location available for user to write :) Not running UE as root, knowing it is still unstable

Should be updated to either 5 or 4.27.2

@aknarts, UE5+ has a lot of issues with broken project performance and compilation issues on Arch. “essentially the same thing.” ? Doesn't sound at all the same based on what you said about precompiled? Too many issues, with UE5. Any UE4 project is screwed updating until a number of issues are fixed relating to performance. Most see less than half performance simply swapping over.

aknarts commented on 2022-05-09 11:12 (UTC)

5.0.1 builds fine and runs fine on Arch, so does 5.0.2 from the 5.0 branch. Also the installed build works fine, well I only download precompiled through Epic Asset Manager so I do not have to compile, but it is essentially the same thing.

OdinVex commented on 2022-05-08 06:21 (UTC)

@Spanner_Man, UE5+ so far has a lot of issues, including compilation on Arch. Completely useless for UE4 projects migrated.

@zerophase - 5.01 was released approx 19 days ago at the time of this comment https://github.com/EpicGames/UnrealEngine/releases/tag/5.0.1-release

CtHx commented on 2022-05-04 16:22 (UTC)

Let me know please, if any of UE versions is possible to build on current archlinux :) I tried but no luck for me...

OdinVex commented on 2022-05-03 14:17 (UTC)

@ShalokShalom, v5 is a broken turd right now, needs a lot of issues fixed. This package should be held back until then.
