I built the Unreal Source for Linux but it crashes on startup

I followed https://docs.unrealengine.com/en-US/Platforms/Linux/BeginnerLinuxDeveloper/SettingUpAnUnrealWorkflow/index.html
and https://github.com/EpicGames/UnrealEngine

Here’s my debug logs:



- Existing per-process limit (soft=524288, hard=524288) is enough for us (need only 524288)
Increasing per-process limit of core file size to infinity.

I have the same problem. Ubuntu 20.04 AMD Radeon VII driver v20.20. It might have started after I updated the amdgpu.

Edit: I’ve solved it by uninstalling AMD drivers. Installing or Uninstalling AMDGPU — amdgpu graphics and compute stack unknown-build documentation

Regards

I had the same problem on Ubuntu 20.04 AMD Radeon RX 470~ . Also solved by uninstalling the drivers :confused: (did not had to recompile)

driver Revision Number 20.30 Release Date 7/30/2020

I would like to be able to make those drivers work though

Same problem here with Debian Testing with kernel 5.6 and amdgpu-pro drivers 20.30.
I cannot uninstal amdgpu-pro drivers because I need OpenCL enabled for other software to work…

Installing the amd-gpu-pro 20.40 drivers fixed this issue for me
