std::isnan 尚未声明，g++-5

Question

我正在尝试使用 nvcc 和 g++-5 编译我的程序，但出现此错误。

In file included from /usr/include/glm/detail/func_common.hpp:426:0,
             from /usr/include/glm/detail/func_geometric.inl:5,
             from /usr/include/glm/detail/func_geometric.hpp:113,

             from src/controls.cpp:6:

   using std::isnan;
          ^
/usr/include/glm/detail/func_common.inl:659:14: error: ‘std::isinf’ has not been declared
   using std::isinf;

使用 g++ 可以正确编译，但 nvcc 需要 g++-5。有谁知道如何解决这个问题？顺便说一下，一旦我运行 sudo do-release-upgrade 在 Ubuntu.

上发生这种情况

nvcc --version 输出是这样的：

我正在使用 c++11 进行编译，但我的源文件中未包含 cmath。这是我的 CMakeLists.txt.

cmake_minimum_required(VERSION 3.7 FATAL_ERROR)
set(CMAKE_C_COMPILER /usr/bin/gcc-5 CACHE PATH "" FORCE)
set(CMAKE_CXX_COMPILER /usr/bin/gcc-5 CACHE PATH "" FORCE)

Answer 1

std::isnan 和 std::isinf 在 <cmath> 中从 C++11 开始声明。 header 包括在内吗？是否在 C++11 或更高版本的模式下完成编译？

Answer 2

您需要使 nvcc 到运行在 C++11 模式下托管 C++ 编译器（将此选项直接传递给 gcc 是不够的）：

 nvcc -Xcompiler "-std=c++11"
