@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.

@CtHx o_o

Use the PKGBUILD I already provided below. There's significant differences between UE4 and 5 and just changing the version at the top is not how that works.

@Neko-san I did only small modifications (changed to the latest version: 4.27.2 and 5.0.1, for 5x version added DOTNET_SYSTEM_GLOBALIZATION_INVARIANT=1 in prepare() section). Fixing .SRCINFO didn't solve my problem. For UE5 I have similar errror:

@CtHx one of the command used for the "running mono" line (one of the dash arguments probably) is considered invalid. Did you modify the PKGBUILD at all?

Also, be sure to delete the hidden .SRCINFO file if you haven't and generate a new one prior to building: makepkg --printsrcinfo >> .SRCINFO

CtHx commented on 2022-04-28 15:35 (UTC) (edited on 2022-04-28 16:02 (UTC) by CtHx)

I have this compilation error (for UE4 and 5):

What am I doing wrong?

ChrisLane commented on 2022-04-22 09:12 (UTC)

5.0.1 was released. Can we get an update please?

william341 commented on 2022-04-17 10:32 (UTC)

@joshtau @Neko-san You can work around the ICU issue by setting DOTNET_SYSTEM_GLOBALIZATION_INVARIANT=1.

OdinVex commented on 2022-04-17 10:21 (UTC)

@chovy, 5.0 is a buggy pile, seriously wrecks almost all v4 projects and v5 has issues on its own. Might be best to wait for a 5.1 or 5.2.

Neko-san commented on 2022-04-17 07:25 (UTC) (edited on 2022-04-17 07:27 (UTC) by Neko-san)

@joshtau icu recently had an update, so this is probably why the script is complaining; I wouldn't personally be able to give an answer for why this particular issue occurs though :/

The only advice I can give for this, until someone finds a more concrete solution or Epic supports the newer versions, is to downgrade and hold the icu package(s) prior to building

joshtau commented on 2022-04-17 07:14 (UTC)

Thanks nekosan, I can compile this manually but using the script throws this error:

Process terminated. Couldn't find a valid ICU package installed on the system. Set the configuration flag System.Globalization.Invariant to true if you want to run with no globalization support.

Not sure why, as icu and friends are installed.

chovy commented on 2022-04-17 01:41 (UTC)

5.0 is out now
