I have built a win10 and Linux Ubuntu 16.04 + following How-To Install/Uninstall AMD Radeon™ Software AMDGPU-PRO Driver for Linux® on an Ubuntu System and get the same issues with openCL recognised as being there but all applications fail to be able to use it.
Is there anything I can run and provide you output to give you some thing to work on? The app logs just say OpenCL error -48 but I'm unsure if that's a local app error code or openCL.
Is openCL being broken a known issue? I couldn't find any ref to it in any release notes or articles.
