Setup.sh fails on Gentoo

Development Programming & Scripting C++

Greetings everyone.

Does anyone have a working UE4 development environment on Gentoo?

I’m following the guide at A new, community-hosted Unreal Engine Wiki - Announcements - Unreal Engine Forums

The following steps are outlined:



$ git clone https://github.com/3dluvr/UnrealEngine.git
$ cd UnrealEngine
$ ./Setup.sh
$ ./GenerateProjectFiles.sh

This procedure fails on my system when executing the Setup.sh script with the following error:



$ ./Setup.sh 
Registering git hooks... (this will override existing ones!)
./Setup.sh: line 33: lsb_release: command not found
./Setup.sh: line 33: lsb_release: command not found

Building ThirdParty libraries

If you don't see SUCCESS message in the end, then building did not finish properly.
In that case, take a look into /home/cwo/9_archive_main/unreal_engine_4/UnrealEngine/UnrealEngine/Engine/Build/BatchFiles/Linux/BuildThirdParty.log for details.

**********  SUCCESS ****************

I have dev-lang/mono-2.10.9-r2::gentoo installed.

Mono 2.x is too old, install the latest first. Also - GitDependencies.exe in master have been recently rebuilt to target 4.0 framework instead of 4.5. I’ll ping amigo (3dluvr) to make sure this (https://github.com/EpicGames/UnrealEngine/commit/8709c61b235481dc57864017fd7f219ae7c7e0bf) gets merged to his branch.

Installed dev-lang/mono-3.2.8::gentoo and the Setup.sh script now proceeds with downloading files. Thanks, I’ll see how this turns out.

I am now at this step:



$ make ShaderCompileWorker UnrealLightmass UnrealPak UE4Editor

My system locks up when performing this. I’ve tried this twice, and I’ve noticed that my RAM usage is at 100% with 50% swap usage when this occurs. I have 6 GiB RAM and 2 GiB swap. Even after waiting it doesn’t appear the kernel OOM killer works correctly (namely by killing the compilation process).

Is there some way to limit the amount of memory consumed by this process so that I can avoid this issue?

You will need to edit the UBT source code and change the total number of cores available…

But 6GB is just not enough to do anything, really.

6

What is the minimum RAM requirement?

7

Official Epic requirements are 8GB. (Häufig gestellte Fragen - Unreal Engine)
