c++ - GLM 无法使用 g++/C++11 进行编译

Question

我正在尝试使用 GLM对于一个游戏项目，但是当使用 g++ 和 -std=c++11 编译时，我遇到了很多编译错误。

这是我要编译的代码:(取自 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;
}

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 中找到某些函数 - 但如果我在包含 glm 之前包含 cmath，这些错误仍然存​​在。

有什么建议吗？

这似乎是 GLM 版本 0.9.7 的错误。降级到 0.9.5 为我解决了这个问题。它被跟踪为 issue 405 .
