Centralized installation of Unreal Engine possible on Linux?

Hi there!

First of all, this is my first day with Unreal Engine and I’m an absolute newby. So, please forgive me, if this might be a very obvious question.

We are trying to run Unreal Engine on Linux and I was able to download the source code, compile it locally and run it afterwards. It takes some time to start up since it does a bunch of compilations on the fly, but from what I get in the documentation, this seems to be normal.

My question concerns a centralized installation of Unreal Engine. We have a environment management system using ‘modules’ on Linux to define environment variables pointing all necessary locations on the server to be able to run different applications. Those locations have no write permissions, to be sure that no user does modify any installed package. Now, I try to copy my compiled Unreal Engine as well, set PATH and LD_LIBRARY_PATH to the …/Engine/Binaries/Linux folder. I can start Unreal Engine with ‘UE4Editor’, but during the startup, I get following messages:



chmod: changing permissions of ‘bin/mcs’: Operation not permitted
chmod: changing permissions of ‘bin/xbuild’: Operation not permitted


Then comes a long list of errors. Here’s just some lines extracted:

And when Unreal Engine finished the loading, I get this window popping up:


Is it possible to have a centralized installation of Unreal Engine? And what do I need to setup to make it work?

Another question is what exactly do I need to install to have a working package? Now, I just copy the entire source code folder structure with the compiled binaries and this is just huge (83GB).

Thanks for any help,
