Unreal Engine editor building failed on Linux with a fresh install

Hello,

New UE user here

Branched the Unreal Engine repo. Pulled it to my machine.

Following linux instructions, i ran Setup.sh which was successful, followed by GenerateProjectFiles.sh which worked also. No errors or warnings.

I proceeded to make but there are a lot of errors, for example:

Could somebody advise on a solution? Is there a version I should try that’s more stable?
