Fresh install of CentOS 7.4 with amdgpu-pro 17.50. Followed installation directions explicitly.
After: amdgpu-pro-install --opencl=legacy --headless
Success. Reboot.
Next:
# /opt/amdgpu-pro/bin/clinfo
terminate called after throwing an instance of 'cl::Error'
what(): clGetPlatformIDs
Aborted
It's as simple as that. What gives?
