安裝GLEW和GLFW

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

brew install glew
brew install glfw3

Xcode工程中的設(shè)置

• Build Settings的Header Search Paths添加路徑/usr/local/include
• Build Phases的Link Binary With Libraries中，添加OpenGL.framework，libGLEW.2.0.0.dylib，libglfw.3.2.dylib這三個(gè)庫

寫點(diǎn)代碼看看：

#include <GL/glew.h>
#include <GLFW/glfw3.h>

int main(void)
{
    GLFWwindow *window;
    
    // 初始化庫
    if (!glfwInit()) {
        return -1;
    }
    
    // 創(chuàng)建 window 和 opengl context
    window = glfwCreateWindow(640, 480, "Hello World ! ", NULL, NULL);
    if (!window) {
        glfwTerminate();
        return -1;
    }
    
    // 得到window的context
    glfwMakeContextCurrent(window);
    
    // 循環(huán)，直到用戶關(guān)閉window
    while (!glfwWindowShouldClose(window)) {
        glClear(GL_COLOR_BUFFER_BIT);
        
        // 渲染. 所有OpenGL的代碼放在這兒
        // ...
        
        // 交換緩存
        glfwSwapBuffers(window);
        
        // 處理事件
        glfwPollEvents();
    }
    
    glfwTerminate();
    return 0;
}
