boinc-client works now when I do:
apt-get remove ocl-icd-libopencl1
apt-get install nvidia-libopencl1-343
apt-get install ocl-icd-libopencl1 (this will remove nvidia-

I am running ubuntu 14.04 64 bit and nvidia drivers 331.38 and had the
same problem of OpenCL not being available in Darktable.
This got fixed for me by a solution proposed to fix another OpenCL issue here:
Thanks for all your comments! I will definitely take note of yours,
Richard, for the next time I reinstall Ubuntu (14.10), provided the
issue still occurs.

For what it is worth - I have been through **almost** all of v304
(nvidia-current from USC) to latest xorg-edgers - in the end, here is
the only currently working option for me, pseudo-code;
purge-ppa ppa:xorg-edgers # purged the mesa libraries mentioned above among
other things.
apt-get purge
I think this is something that is unrelated to nvidia and/or darktable -
I had updates of lib-mesa on 2014-07-10 (Thursday) and believe I
didn't run darktable much yesterday (Friday).
It seems as darktable at least gets a bit further, with opencl_library

For what it is worth: I have pulled out nvidia-340 (xorg-edgers) and am
now down to 331.89 and settings from -340 - makes no difference.

Thanks for reporting this The Bright Side, but this issue is much bigger
than darktable.
The fact that clinfo gives a weird error is a good indicator that this
is a very general problem, not related to any user-land programs. The
reason I found it (again, thanks) was that I have a problem with
