Unreal engine 4.27 build crashes (SIGSEGV) on Linux

Xin_Riv · July 31, 2024, 4:55am

I was able to build unreal engine 4.27 on my Ubuntu 22.04 without issues but it failed to build weeks ago and the call stack shows Vulkan related function (libUE4Editor-VulkanShaderFormat.so!DoCompileVulkanShader). Building it on Windows is still fine.

Tried a couple of different versions of NVidia drivers (535, 545 and 550) with same results. Other posts mentioned installing correct libnvida-gl-xxx packget fixed their SIGSEGV crashes but the package is already installed on my Ubuntu.

Wonder anyone had similiar issue and a solution to this.

Anyway, here’s the call stack from book log file:

Just tried to build with Ubuntu’s Nouveau display driver and the build still failed and the call stack is very similar to the one built with nVidia driver installed, only the very top fuctions in libdxcompiler.so are different.
