[Bf-cycles] cycles compilation error on linux

[Thomas Beck]

Hi Thomas, Hi inS,

I have a fairly similar problem with cycles in trunk since Brecht committed
the fire stuff. As I'm under Linux, the kernel gets compiled when I hit
F12, but it's the same error - segmentation fault while compiling the
kernel.
The (temporary) solution for me is atm to compile it by hand with a bigger
amount of registers: 40 instead 32. That works perfectly in my case. I got
2 GTX 560 ti oc here.

The complete command line:

"nvcc" -arch=sm_21 -m64 --cubin
"/home/neo/blender-git/official/build/bin/2.70/scripts/addons/cycles/kernel/
kernel.cu" -o
"/home/neo/.config/blender/2.70/cache/cycles_kernel_sm21_B018C3AD80E620A16AE2F993E1CBAE9F.cubin"
--ptxas-options="-v" --maxrregcount=40 --use_fast_math
-I"/home/neo/blender-git/official/build/bin/2.70/scripts/addons/cycles/kernel"
-DNVCC -D__KERNEL_CUDA_VERSION__=50

Maybe you could try to compile it manually and tell us if increasing the
register size fixed your issue too.

Greetings, Thomas
