<div dir="ltr"><div><div>Hi Thomas, Hi inS,<br><br></div>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.<br>
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.<br><br></div>The complete command line:<br><div><br>
"nvcc" -arch=sm_21 -m64 --cubin "/home/neo/blender-git/official/build/bin/2.70/scripts/addons/cycles/kernel/<a href="http://kernel.cu">kernel.cu</a>" -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<br>
<br></div><div>Maybe you could try to compile it manually and tell us if increasing the register size fixed your issue too.<br><br></div><div>Greetings, Thomas<br></div></div><div class="gmail_extra"><br><br><div class="gmail_quote">
