Comment 13 M. Edward (Ed) Borasky 2017-03-19 08:25:52 UTC 
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.
