This isn't really a clpeak bug - it's actually a pocl / documentation issue. How to reproduce: 1. Start with a clean system. 2. Install pocl and clpeak 3. Run clpeak ... it will crash. So will libreoffice-math, which is how I found this. The culprit in both cases is a missing "clang". Just installing pocl isn't enough; you have to install pocl-devel to get clang and some other OpenCL dependencies. I'm putting OpenCL through a lot of testing and filing bugs; once all the bugs are wrung out I can write a blog post about running OpenCL on Fedora with pocl and an AMD GPU.
