@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).

@zerophase: exactly the same, SensibleEditorSourceCodeAccess less. Oddly enough, I use downgrade to install clang 3.8 and I manually compile everything from scratch (foolowing https://wiki.archlinux.org/index.php/Unreal_Engine_4 and https://wiki.unrealengine.com/Building_On_Linux#Building), everything worked fine.

@mnivoliez What's the error message this time?

mnivoliez commented on 2018-05-22 20:04 (UTC)

@zerophase: removing SensibleEditorSourceCodeAccess didn't solve the issue. I still got the same error.

@mnivoliez looks like SensibleEditorSourceCodeAccess is the issue. It's built for a different version of the editor. Either remove it, update it, or fix the warnings involving it. Willing to bet if you remove it the project will compile. This isn't an issue with the package.

@zerophase It still do not work. I think the problem come from the project build delete the library. Here is the log with some additional commands.

@Mnivollez you need to add every file in the unreal directory to the unreal group.

This will do it: chgrp unreal -Rf /opt/unreal-engine; chmod 775 -Rf /opt/unreal-engine/

Ok, so I can see the file:

locate libUE4Editor-UnrealEd.so: /opt/unreal-engine/Engine/Binaries/Linux/libUE4Editor-UnrealEd.so /opt/unreal-engine/Engine/Intermediate/Build/Linux/B4D820EA/UE4Editor/Development/Relink-libUE4Editor-UnrealEd.so.sh /opt/unreal-engine/Engine/Intermediate/Build/Linux/B4D820EA/UE4Editor/Development/libUE4Editor-UnrealEd.so.response

I got permission to read, write and execute him.

But, for unknown reason, when doing make into the project directory:

ERROR: UBT ERROR: Failed to produce item: /opt/unreal-engine/Engine/Binaries/Linux/libUE4Editor-UnrealEd.so

And then, sudo updatedb && locate libUE4Editor-UnrealEd.so:

/opt/unreal-engine/Engine/Intermediate/Build/Linux/B4D820EA/UE4Editor/Development/Relink-libUE4Editor-UnrealEd.so.sh

/opt/unreal-engine/Engine/Intermediate/Build/Linux/B4D820EA/UE4Editor/Development/libUE4Editor-UnrealEd.so.response

The library seems to have disappear.

About the idea of creating a group, I know how to add a group and add myself to it, but create a group for unreal... not so much. Any hint would be appreciated.

@mnivoliez I'll need more information to help you.

When are you getting:

/opt/unreal-engine/Engine/Binaries/Linux/UE4Editor: error while loading shared libraries: libUE4Editor-UnrealEd.so: cannot open shared object file: No such file or directory

When compiling a new project?

You could try creating a group for your unreal install, and adding yourself as a group member. If it's an issue with compiling a project that should fix it.

mnivoliez commented on 2018-05-14 19:21 (UTC)

I am confirming that the error still persist even after update. I will try to follow the official procedure describe on their guide.
