Now I am using C++14, but errors comes out.
So what do you think about the second error?

…/test/cpp/jit/test_gpu.cpp:1633:47: error: converting to ‘std::tuple<at::Tensor ( )(const at::Tensor&), torch::jit::fuser::UnaryOpType, std::__cxx11::basic_string<char, std::char_traits, std::allocator > >’ from initializer list would use explicit constructor ‘constexpr std::tuple< >::tuple(_UElements&& …) [with _UElements = {at::Tensor (&)(const at::Tensor&), torch::jit::fuser::UnaryOpType, const char (&)[4]}; = void; _Elements = {at::Tensor ( )(const at::Tensor&), torch::jit::fuser::UnaryOpType, std::__cxx11::basic_string<char, std::char_traits, std::allocator >}]’
{at::trunc, UnaryOpType::Trunc, “trunc”}};

Is there a solution?
Thank you!
