GLM fails to compile with g++/C++11

I'm trying to use GLM for a game project, but when compiling with g++ and -std=c++11, I'm getting a lot of compile errors.

This is the code I'm trying to compile: (taken from here)

#include "glm/vec3.hpp"
#include "glm/gtx/io.hpp"
#include <iostream>

using namespace std;
using glm::vec3;

int main () {
    vec3 i_am_zero;

    cout << i_am_zero << endl;
    return 0;
}

My command line:

g++ -std=c++11 test.cpp -o test.exe

The compiler output:

It appears that it can't find some functions from cmath - but these errors still remain if I include cmath before I include glm.

Any advice?

It appears that this is a bug with GLM version 0.9.7. Downgrading to 0.9.5 resolved the problem for me. It's being tracked as issue 405.

This compiles and runs just fine with gcc 4.8.2 at c++11 standard on my machine.

I get a series of warnings

/usr/include/glm/gtc/quaternion.inl:639:165: note: #pragma message: GLM: rotate function taking degrees as a parameter is deprecated. #define GLM_FORCE_RADIANS before including GLM headers to remove this message.

But if I change the code to 

#define GLM_FORCE_RADIANS
#include "glm/vec3.hpp"
#include "glm/gtx/io.hpp"
#include <iostream>

using namespace std;
using glm::vec3;

int main () {
    vec3 i_am_zero;

    cout << i_am_zero << endl;
    return 0;
}

then it compiles fine with -Wall -Werror.

The glm header includes cmath, so including it again shouldn't change things for you.

I am using GLM version 0.9.5. You might want to upgrade your GLM version maybe and / or compiler version?
