CUDA compilation failed 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 ...

       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.
With *buntu 20.04, modify the blender.desktop launcher to:

CYCLES_CUDA_EXTRA_CFLAGS="-ccbin clang-8" blender


As per the Blender web page as of 07-April-2020, Blender is not compatible with gcc 4.7 or higher.

The above command will launch Blender with compiler settings compatible with 20.04. The 1st GPU render requires a few minutes to compile the CUDA renderer, but afterwards renders will run immediately. Nvidia 1080 CUDA rendering was 6× faster than my old 4771 CPU alone.
