Question

嗨，我正在用g ++编译器的glad.h头文件进行图形编程。这是我的代码。我将展示包含关系。

这是Animation.cpp中包含文件的列表

#include <glad/glad.h>
#include <GLFW/glfw3.h>
#include <glm/glm.hpp>
#include <glm/gtc/matrix_transform.hpp>
#include <glm/gtc/type_ptr.hpp>
#include "Shader.h"
#include "Camera.h"
#include "Bone.h"

这是Bone.h中包含的文件的列表

#include <glad/glad.h>
#include <GLFW/glfw3.h>
#include <glm/glm.hpp>
#include <glm/gtc/matrix_transform.hpp>
#include <glm/gtc/type_ptr.hpp>
#include "Shader.h"
#include "Camera.h"

（Animation.cpp，Bone.h，Shader.h，Camera.h都在同一目录中）

我再次检查了我的glad.h头文件是否在目录/ usr / local / include / glad中，并且确实存在。然后，我使用命令添加了环境变量

export CPLUS_INCLUDE_PATH=/usr/local/include

最后，我尝试使用以下命令执行代码

g++ Animation.cpp -o Animation -framework OpenGl -lglfw.3

但是，显示以下错误代码。

显然，链接器似乎找不到我通过CPLUS_INCLUDE_PATH变量指定其路径的glad.h文件。任何帮助将不胜感激如何解决这个问题。预先感谢！

即使设置了包含路径（OpenGL），g ++也找不到glad.h
