nvidia.icd file is not present in nvidia-current 64bits. Fail to load opencl (like darktable)

[kikislater]

Under Ubuntu 12.04 precise pangolin, I'm unable to load darktable with opencl with an optimus nvidia graphic card.

I've got this error :
$ optirun darktable -d opencl
[opencl_init] trying to load opencl library: ”
[opencl_init] opencl library ‘libOpenCL’ found on your system and loaded
[opencl_init] could not get platforms: -1001
[opencl_init] FINALLY: opencl is NOT AVAILABLE on this system.
[opencl_init] initial status of opencl enabled flag is OFF.

To solve the problem I have to create a file : nvidia.icd in /etc/OpenCL/vendors/ with the only content being libcuda.so

After that I got it working.

changing it to libcuda.so didnt work for me, ive put the following in: libnvidia-opencl.so.304.43
altough this isnt in combination with darktable. ( generic OpenCL app )

You should try to with 295 driver if you use darktable

I've also noticed this bug.

If you want to fix it manually, simply use following command:

    echo libnvidia-opencl.so.1 | sudo tee /etc/OpenCL/vendors/nvidia.icd # for new drivers

or following one:

    echo libcuda.so | sudo tee /etc/OpenCL/vendors/nvidia.icd # for old drivers

I use the 12.04 LTS with nvidia-current-updates and ubuntu-x-swat/x-updates PPA, co I have to use the first command.

Thanks for your reply

Note that with Ubuntu 13.10, and the 319-updates driver, I needed:

libnvidia-opencl.so.319.60

Found by looking at the "installed files" tab of nvidia-319-updates package in synaptic, and realising that libnvidia-opencl.so.1.

Same for 14.04 and driver 340.93. Is there a solution?
