'make' fails when trying to build UE4 for Linux

Hey all

I am trying to follow this guide

however, when entering ‘make’ in the Building UE4 on Linux phase, I get the following error:

I am clueless. searched the web for a solution but didn’t find anything useful.

Thank you for your help

Are you trying to build most recent version (which is 4.26) of Unreal?
Try to go to
and check whether v17_clang-10.0.1-centos7 exists there.

If not - run Setup.sh from root of Unreal source code repositoy.

Anyway, I’m do not recommend to use UE4 on Linux because it’s pure piece of garbage: horrible startup time (10 times more than on Windows), instant crashes everywhere, lot of things not working properly in Vulkan mode.

Just switch to Windows.
