windows 下最简单的glfw 工程

#include <GLFW/glfw3.h>

#ifdef _WIN32
    #pragma comment(lib,"opengl32.lib")
    #pragma comment(lib,"glfw3.lib")
#endif // 

const int WIDTH = 640;
const int HEIGHT = 480;


int main(int argc, char** argv){

    glfwInit();

    GLFWwindow* window = glfwCreateWindow(WIDTH, HEIGHT, "OGL_APP1", NULL, NULL);
    if (window == nullptr){
        glfwTerminate();
        return -1;
    }

    glfwMakeContextCurrent(window);

    while (!glfwWindowShouldClose(window)){

        glClearColor(0, 0, 1.0, 0.0);
        glClear(GL_COLOR_BUFFER_BIT);

        glfwSwapBuffers(window);
        glfwPollEvents();
    }
    return 0;
}
