[Bf-committers] Clang errors when compiling the Cycles CUDA kernel in Blender

[Sen Haerens]

Hi,

I'm getting the following Clang errors when trying to compile the Cycles
CUDA kernel in Blender.

Read new prefs: /Users/sen/Library/Application
Support/Blender/2.69/config/userpref.blend
found bundled python:

clang: error: no input files
CUDA kernel compilation failed, see console for details.

These are my build specs:
