Bug Description

** Steps to Reproduce: **
1. Perform a fresh installation of Ubuntu Gnome 14.04 64-bit on a clean PC
2. Using the "Additional Drivers" application, install latest NVidia driver (331)
3. Reboot
4. Install latest Darktable (1.4) from Ubuntu's repositories
5. In Terminal, run "darktable -d opencl"

** Actual Result: **
In Ubuntu Gnome 14.04, using the NVidia 331 driver, Darktable won't run with OpenCL support. The following debug output is observed in the terminal:

** Expected Result: **
Software using OpenCL should continue to work as it did in Ubuntu 13.10.

** Notes: **
Graphics card: GeForce GTX 680 (Gigabyte GV-N680OC-2GD)
Encuontered on Ubuntu Gnome 14.04, 64 bit.
Likely occurs on regular Ubuntu (not Ubuntu Gnome) as well.
This issue also occurs when running NVidia 331 Update, NVidia Legacy 304 as well as Nouveau.
This issue did not occur on Ubuntu Gnome 13.10.
Bug filed in Darktable: http://www.darktable.org/redmine/issues/9913#change-24936

** Troubleshooting: **
The following files and directories relating to OpenCL were found on the test system:

locate -i libopencl
/usr/lib/i386-linux-gnu/libOpenCL.so.1
/usr/lib/i386-linux-gnu/libOpenCL.so.1.0

installed the packages "opencl-headers" and "nvidia-profiler", but that made no difference.
Manually edited /etc/ld.so.conf to include the directories found containing the OpenCL libraries (from the list above). Ran ldconfig. 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 boinc-client. As soon as I upgraded to 14.04, boinc-client stopped being able to detect any OpenCL resources.

This is an OpenCL driver problem with the nVidia drivers.

I think this is link is relevent, which says to install nVidia drivers manually:

https://devtalk.nvidia.com/default/topic/734098/linux/-boinc-ubuntu-nvidia-no-usable-gpus-found-/

I'm just trying to figure out if that is worth doing or if Ubuntu folks are going to fix it soon.

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=libnvidia-opencl.so.1" in "~/.config/darktable/darktablerc"

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.

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 nvidia* nvidia-opencl* nvidia-libopencl* libcuda1*
sh NVIDIA-Linux-x86_64-340.17.run

dkms registration of modules -> "not necessary"
gcc 4.6 used for driver, gcc 4.8 on system -> CC check ignored.

Now:
$ dpkg --list | grep -E '^ii.*(nvidia|cuda)'
displays 'ii nvidia-settings 331.20-0ubuntu8'

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:
http://askubuntu.com/questions/449507/nvidia-libopencl1-331-has-to-be-removed-before-installing-wine?rq=1

What I did was:

sudo apt-get install nvidia-cuda-toolkit

and then

sudo apt-get install ocl-icd-opencl-dev

After a reboot, Darktable's "activate OpenCL support" is not greyed out anymore and seems to work like it should.

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 14.04, I fixed the problem with a symlink as described here:

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-libopencl1-343, but it works)

I think some configuration or detritus from "nvidia-libopencl1-343" gets left behind such that ocl-icd-libopencl1 can use it.

For Darktable, I'm pretty sure all you'll need to do is install the nvidia-modprobe package after you activate the Nvidia drivers. It'll then work without any further ado. Let me know if that does the trick for you - it's been working for me over the past 3 Ubuntu releases, across 3 PCs.
