GLM 无法使用 g++/C++11 进行编译

Question

我正在尝试将 GLM 用于游戏项目，但是在使用 g++ 和 -std=c++11 进行编译时，出现了很多编译错误。

这是我要编译的代码：（摘自 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？

Answer 1

这在我的机器上以 c++11 标准使用 gcc 4.8.2 编译和运行得很好。

我收到一系列警告

/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.

但是如果我将代码更改为

#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;
}

然后用 -Wall -Werror 编译很好。

glm header 包含 cmath，因此再次包含它不会对您有所改变。

我正在使用 GLM 版本 0.9.5。您可能想要升级您的 GLM 版本和/或编译器版本？

Answer 2

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