Have installed amdgpu-pro 20.45 under RHEL 8 (/amdgpu-pro-install -y --opencl=rocr,legacy). Okay so far - but building UnrealEngine from source UE4Editor does not start, saying no vulkan driver detected, although Vulkan Pro and amd mesa is installed.
Have had an FEDORA 33 installation before, which worked with the standard kernel drivers (5.10.7) and mesa / vulkan / rocm.
Any similar experience / solutions?
