Hey,
today made a linux build and tried to compile the CUDA kernels for my graphics card (one PC): GTX550Ti and GTX760
The GTX550Ti compiles fine, but for the GTX760 I always get the typical CUDA compile error with a “Segmentation fault”.
florian@florian-desktop ~/Entwicklung/blender-git/build_linux/bin $ ./blenderfound bundled python: /home/florian/Entwicklung/blender-git/build_linux/bin/2.70/python

Segmentation fault
CUDA kernel compilation failed, see console for details.
Refer to the Cycles GPU rendering documentation for possible solutions:
http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/GPU_Rendering
The GTX760 is also my display graphics card, while the GTX550Ti is just for rendering. In older builds both worked together for rendering. The problem is that my last linux build was quite old so I can’t say since which commit this is broken.
Blender version: df5cbfb, latest GIT-version
CUDA toolkit:5.0.35
NVidia driver: 319.60
OS: Linux Mint 16 (based on Ubuntu 13.10)
Thanks for your help,
Florian
EDIT: Rendering with the buidbot-version with the GTX760 works…
