When I try to render with the Cycles render on my GPU I'll get a message which says that my CUDA compilation failed and I get this error in the console;

Compiling CUDA kernel ...
"nvcc" -arch=sm_61 --cubin "/usr/share/blender/scripts/addons/cycles/kernel/kernels/cuda/kernel.cu" -o "/home/nils/.config/blender/2.78/cache/cycles_kernel_sm61_E317D1655098C1EB89BEC29AC2C7B15D.cubin" -m64 --ptxas-options="-v" --use_fast_math -DNVCC -D__KERNEL_CUDA_VERSION__=80 -I"/usr/share/blender/scripts/addons/cycles/kernel" 
ERROR: No supported gcc/g++ host compiler found, but clang-3.8 is available.
       Use 'nvcc -ccbin clang-3.8' to use that instead.
CUDA kernel compilation failed, see console for details.

Graphics card: Nvida Geforce GTX 1050ti (gigabyte= Processor: Intel core i5 6400 (4x2.7GHz) 16gb ddr3l 1600

I have already installed gcc, g++, clang, and all Nvida drivers.

I'm having exactly the same issue. After seeing the error message, and the posts here, here, and here, I think the problem was caused by nvcc not supporting the newer compiler versions installed on Debian by default. For me, the problem was solved by using the Blender 2.79 release candidate instead. I think it may also be solved by installing older versions of the compiler.
