Blender don't work with CUDA

I confirm this issue on my test computer.

Please try the following. 

1. Install/update nvidia-cuda-toolkit and nvidia-cuda-toolkit-devel (both are needed) to version 7.0.28 from this container:


By the way, since CUDA 7.0, only 64-bit Linux systems are supported, it seems.

2. Blender looks for libcuda.so, so make a symlink for it (replace "nvidia346" with an appropriate name if you use a different NVidia driver):

ln -s /usr/lib64/nvidia346/libcuda.so.1 /usr/lib64/libcuda.so

Perhaps, this should be done automatically in the future updates for nvidia*-cuda-opencl.

3. Run Blender and see if it can work with CUDA now.

Blender 2.74 seems to support CUDA 6.5 only, so here is CUDA toolkit 6.5:
Comment 4 Eugene Shatokhin 2015-05-28 17:42:35 MSD
CUDA toolkit was updated to version 6.5 that Blender 2.74 supports. CUDA toolkit 7.0 seems to still have problems, so we are updating it only to version 6.5 for the present.
Release notes: http://developer.download.nvidia.com/compute/cuda/6_5/rel/docs/CUDA_Toolkit_Release_Notes.pdf

Build lists:
x86_64: https://abf.io/build_lists/2504505

Note that there is only a build for x86_64. Support for 32-bit systems was dropped from CUDA by NVidia in version 7.0 or earlier, no need to bother with it in 6.5 as well.
Comment 5 Vladimir Potapov 2015-05-28 20:22:46 MSD
The update is sent to expanded testing
