Build of UE4Editor on Ubuntu 18.04 fails
I've followed the guide (https://docs.unrealengine.com/en-us/Platforms/Linux/BeginnerLinuxDeveloper/SettingUpAnUnrealWorkflow) and everything worked fine before "make". But every time when I try to "make", I get this error multiple times on different steps:
Sometimes it occurs many times in a row, sometimes very early (first 200 of 1684), sometimes quite late (~700). The make process doesn't stop then, but fails and stops at a later stage, most times with an error like "Failed to produce item ...". I've tried using a local version of clang (5.0.1 and 6.0.0) but same result. My computer is new, but could it be a RAM failure? I haven't done a memtest yet. Do you have any ideas?
edit: works now, see my comment below
I have a very similar system I7 8700, 1080 Ti Ubuntu 18.04 and have been building Unreal Engine on Linux since 4.17. When first attempted 4.21 build my system reliably crashed somewhere in the big build stage similar to your description. What did was to disable hyperthreading (you can also try reducing the number of parallel compile jobs - theres an answer on this hub about which Unreal build parameter to change) then it compiles reliably. It seems if you really are running the processors hard hyperthreading is not good - at least under Linux. I disabled hyperthreading as also having issues with games running under wine also crashing - and this appears to be another known hyperthreading issue.
