尚未使用g ++-5声明std :: isnan

Question

I'm trying to compile my program with nvcc and g++-5 and I get this error.

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 /usr/include/glm/geometric.hpp:6,
             from /usr/include/glm/detail/func_matrix.inl:4,
             from /usr/include/glm/detail/func_matrix.hpp:149,
             from /usr/include/glm/detail/type_mat2x2.inl:4,
             from /usr/include/glm/detail/type_mat2x2.hpp:182,
             from /usr/include/glm/mat2x2.hpp:6,
             from /usr/include/glm/glm.hpp:71,
             from src/controls.cpp:6:
/usr/include/glm/detail/func_common.inl:623:14: error: ‘std::isnan’   has not been declared
   using std::isnan;
          ^
/usr/include/glm/detail/func_common.inl:659:14: error: ‘std::isinf’ has not been declared
   using std::isinf;

Using g++ it compiles correctly, but nvcc required g++-5. Does anyone know how to solve this? By the way, this started happening once I ran sudo do-release-upgrade on Ubuntu.

nvcc --version output is this:

I'm compiling with c++11 and cmath is not included in my source files. This is my CMakeLists.txt .

Answer 1

You need to make nvcc to run host C++ compiler in C++11 mode (passing this option to gcc directly is not enough):

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

details can be found here

Answer 2

std::isnan and std::isinf declared in <cmath> starting with C++11. Is that header included? Is the compile done in C++11 or later mode?

Answer 3

For those interested I solved it changing two lines of CMakeLists.txt like this:

set(CMAKE_C_COMPILER /usr/bin/gcc-5 CACHE PATH "" FORCE)
set(CMAKE_CXX_COMPILER /usr/bin/g++ CACHE PATH "" FORCE)

Now it compiles correctly, thanks to all willing to help.
