Oh, I'm sorry. I forgot that I had local changes in that tree.
I just did a clean git clone. The tree builds as-is. However,
cryptmd5-opencl still fails at runtime for me, for all three devices
(Nvidia GPU, AMD GPU, CPU) in the same way that I reported in other
messages:

IIRC, this was determined to be some pathname processing error that you
were supposed to fix?
Thanks,
