Unsure what to do... i tried several workarounds i found, but nothing seems to have worked so far. Tried alternative OpenCL Drivers, but got the same error.

Re: FAHClient fails to find working OpenCL Platform

A fix someone came up with was posted here - https://bbs.archlinux.org/viewtopic.php?id=287642. It appeared to be a conflict with the included C++ library from what they reported as fixing the issue.
