Problem with building UE4

Hello everyone,

I´ve got a problem with my first UE4 build, i´m using Debian 8 with an fx 6350 and and gtx 1050ti (but this should not matter).
I followed these A new, community-hosted Unreal Engine Wiki - Announcements - Epic Developer Community Forums Insturctions, but i had to use clang8 insted of clang9.
So ran the setup script then the “GenerateProjectFiles” Script with no errors.After that i typed in make -j6 (I wasn´t sure if he would use all 6 cores if i type just make)
and also that one ran without an error.After that I tried to open up the unrealeditor but the file doesn´t exist.Has anybody an Idea why?

Maybe u should add more information.

Which command do u execute to run the editor?
Which file is missing?
Whats the exact error code?
Stack trace?
