Add -gencode to match all the GPU architectures you have.
Check 'https://en.wikipedia.org/wiki/CUDA#GPUs_supported' for list of architecture.
Check 'http://docs.nvidia.com/cuda/cuda-compiler-driver-nvcc/index.html' for GPU compilation based on architecture.

I have tried put export CXXFLAGS="-std=c++11" export CFLAGS="-std=c99" in the setup.sh and build_toolbox.sh ,but it did not work.

[jordgey]

And I install CUDA9.0 today, but error not changed.

Would you mind share your gcc version? Thank you very much!
