GLM无法使用g ++/C++编译11

Question

我试图使用GLM作为游戏项目，但是在使用g ++和-std = C++ 11编译时，出现了很多编译错误。

这是我想要编译代码：（从here拍摄）

#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; 
} 

我的命令行：

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

编译器输出：

它似乎无法从cmath中找到某些功能 - 但如果包含cmath，这些错误仍然存​​在在我包括glm之前。

有什么建议吗？

Answer 1

看来这是一个GLM版本0.9.7的bug。降级到0.9.5为我解决了这个问题。它被追踪为issue 405。

Answer 2

这个编译和运行很好，在我的机器上用C++ 11标准的gcc 4.8.2。

，我收到了一系列警告

/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. 

，但如果我的代码更改为

#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; 
} 

然后它编译与-Wall -Werror罚款。

glm标题包括cmath，所以包括它不应该改变你的东西。

我正在使用GLM版本0.9.5。您可能想要升级您的GL​​M版本，可能和/或编译器版本？
