Public bug reported: ** 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: [opencl_init] opencl related configuration options: [opencl_init] [opencl_init] opencl: 1 [opencl_init] opencl_library: '' [opencl_init] opencl_memory_requirement: 768 [opencl_init] opencl_memory_headroom: 300 [opencl_init] opencl_device_priority: '*/!0,*/*/*' [opencl_init] opencl_size_roundup: 16 [opencl_init] opencl_async_pixelpipe: 0 [opencl_init] opencl_synch_cache: 0 [opencl_init] opencl_number_event_handles: 25 [opencl_init] opencl_micro_nap: 1000 [opencl_init] opencl_use_pinned_memory: 0 [opencl_init] opencl_use_cpu_devices: 0 [opencl_init] opencl_avoid_atomics: 0 [opencl_init] opencl_omit_whitebalance: 0 [opencl_init] [opencl_init] trying to load opencl library: '<system default>' [opencl_init] could not find opencl runtime library 'libOpenCL' [opencl_init] no working opencl library found. Continue with opencl disabled [opencl_init] FINALLY: opencl is NOT AVAILABLE on this system. [opencl_init] initial status of opencl enabled flag is OFF. [pixelpipe_process] [thumbnail] using device -1 [pixelpipe_process] [thumbnail] using device -1 ** 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 /usr/lib/i386-linux-gnu/libOpenCL.so.1.0.0 /usr/lib/x86_64-linux-gnu/libOpenCL.so.1 /usr/lib/x86_64-linux-gnu/libOpenCL.so.1.0 /usr/lib/x86_64-linux-gnu/libOpenCL.so.1.0.0 /usr/share/doc/nvidia-libopencl1-331 /usr/share/doc/nvidia-libopencl1-331/changelog.Debian.gz /usr/share/doc/nvidia-libopencl1-331/copyright /var/cache/apt/archives/nvidia-libopencl1-331_331.38-0ubuntu7_amd64.deb /var/lib/dpkg/info/nvidia-libopencl1-331.list /var/lib/dpkg/info/nvidia-libopencl1-331.md5sums /var/lib/dpkg/info/nvidia-libopencl1-331.postinst /var/lib/dpkg/info/nvidia-libopencl1-331.postrm /var/lib/dpkg/info/nvidia-libopencl1-331.shlibs 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.
