这是GLFW的例子,我在Mac OS上使用Xcode运行它：

#include <GLFW/glfw3.h>
int main(void)
{
    GLFWwindow* window;

    if (!glfwInit())  /* Initialize the library */
        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 */

        /* Swap front and back buffers */
        glfwSwapBuffers(window);

        /* Poll for and process events */
        glfwPollEvents();
    }

    glfwTerminate();
    return 0;
}
