Can't build UnrealEngine for Linux

General Issues and Bug Reporting
, ,
1

Hello all, I tried to build UnrealEngine for Linux target, but got error message which will be below. I followed instructions at all, after I installed clang, I rebuild by UE5 and button build project for linux platform was appeared in IDE. Also regenerated project files. Clang is accessible from PATH and works on PC.

Also I tried to cook it with RunUAT:
RunUAT.sh BuildCookRun -project=%ProjectPath% -build -server -noclient -clientconfig=Development -platform=Linux

Output:

Compile Module.InteractiveToolsFramework.cpp
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.

Same. For me, specifically, this is using a Lyra Project that hasn’t kept up with updates. Interestingly, I have no problem doing the same build using the linux cross-compile toolchain.

OH. Clang version, duh! Every. Time.
v22_clang-16.0.6-centos7 is the one you want to use for 5.4. LINUX_MULTIARCH_ROOT & LINUX_ROOT environment variables.
