Question

我正在尝试用nvcc和g ++ - 5编译我的程序，我得到了这个错误。

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

   using std::isnan;
          ^

使用g ++它可以正确编译，但是nvcc需要g ++ - 5。有谁知道如何解决这个问题？顺便说一句，一旦我在Ubuntu上运行sudo do-release-upgrade，就会发生这种情况。

我正在使用c ++ 11进行编译，而cmath不包含在我的源文件中。这是我的CMakeLists.txt。

cmake_minimum_required(VERSION 3.7 FATAL_ERROR)

Answer 1

您需要使nvcc以C++11模式运行主机C ++编译器（直接将此选项传递给gcc是不够的）：

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

详情可以找到here

std :: isnan尚未声明，使用g ++ - 5
