环境搭建

1. 执行brew install glfw

2. 项目中Build Settings中header Search Paths中添加glfw的include路径(/opt/homebrew/Cellar/glfw/3.4/include)

3. 项目中Build Phases中的Link Binary With Libraries中添加glfw的lib文件（路径/opt/homebrew/Cellar/glfw/3.4/lib/libglfw.3.4.dylib）及opengl.framework

代码实现

#include   int main(void) {     GLFWwindow* window;      /* Initialize the library */     if (!glfwInit())         return -1;      /* Create a windowed mode window and its OpenGL context */     window = glfwCreateWindow(640, 480, "Hello World", NULL, NULL);     if (!window)     {         glfwTerminate();         return -1;     }      /* Make the window's context current */     glfwMakeContextCurrent(window);      /* Loop until the user closes the window */     while (!glfwWindowShouldClose(window))     {         /* Render here */         glClear(GL_COLOR_BUFFER_BIT);          glBegin(GL_TRIANGLES);         glVertex2f(0, 0.5f);         glVertex2f(-0.5f, -0.5f);         glVertex2f(0.5f, -0.5f);         glEnd();                  /* Swap front and back buffers */         glfwSwapBuffers(window);          /* Poll for and process events */         glfwPollEvents();     }      glfwTerminate();     return 0; }

在一个电脑遇到错误 dyld: Library not loaded: /usr/local/opt/glfw/lib/libglfw.3.dylib
