Can't install UE4 on linux

After running ./Setup.sh it seemed at first that installation ran smoothly but in the last line it said:

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

And it didn’t have that SUCCESS message in the end. Though I did still try to run ./GenerateProjectFiles.sh after this but it didn’t go far before it cut off. So i looked what was said in BuildThirdParty.log :

I’ve just recently installed Ubuntu 16.04 and I’m not too familiar with the command line, so this doesn’t make any sense to me at all.

And I have tried to run ./Setup.sh again, remove all files, redownload them and run ./Setup.sh again without any succession.

Specs:
CPU: AMD A10-5800K
GPU: Nvidia GeForce GTX 660
8gb ram

I didn’t find anyone having this same problem on the forums, but I sincerely apologise if this question has already been answered before.

Hey TomOskar-

Based on the error message it appears you’re missing clang. You should be able to do a $ sudo apt-get install clang and then run ./Setup.sh again. You can find more information and steps for building the engine on Linux here: A new, community-hosted Unreal Engine Wiki - Announcements - Epic Developer Community Forums

Cheers

Yep, that was it. Thank you very much!

Thanks much - Just downloaded 4.13 source via git and had the same issue - it is odd, because Setup.sh installed some clang packages for ubuntu, but I still had the error until I installed clang with apt.

In case anyone else has the same issue, I am using Ubuntu 16.04 LTS
