In case several OpenCL implementations sharing devel/LLVM > LLVM 3.X are installed, software compiled with the OpenCL backend will fail with an error like: Device open failed, aborting... : CommandLine Error: Option 'enable-value-profiling' registered more than once! LLVM ERROR: inconsistency in registered CommandLine options Nothing to output ! (the error message above has been taken from clinfo, see Bug 231226). This problem seems to be unresolved in LLVM, although known since a couple of years for now. See, for instance, Bug 219562, Bug 224584 where I tried to gather some of the bug reports on LLVM. In case devel/ocl-icd is installed, graphics/blender seem to fail when compiled using OpenCL and option CYCLES - calling blender results in the same error as shown above. To reproduce the error described here, try to have installed mesa,beignet as well as devel/clinfo and devel/ocl-icd and/or lang/pocl. devel/clinfo reveals the problem quickly. lang/pocl is useless if used with an ICD. Can someone help on this? Kind regards, oh
