在Mac终端上编译OpenGL程序

我使用的是完全更新了XCode 6.0.1版本的Mac Os X 10.9.5。我还安装了在安装XCode之后必须安装的命令行实用程序。我在我的openGL库中使用GLFW和GLEW。GLEW是手动安装的，而GLFW是用Macports安装的。

我想在没有XCode的情况下进行编码，因为我一直在Windows（使用MingW）和Linux上进行编码。我在谷歌上搜索了如何编译这个程序，还搜索了stackoverflow。

因此，当前我的编译命令如下（这是一个C++程序）

g++ -framework Cocoa -framework OpenGL -framework CoreFoundation -framework CoreVideo -framework IOKit -L/usr/lib -L/usr/local/lib -I/usr/include/GLFW -I/usr/local/include/GL main.cpp -o main

我不断得到以下错误：

Undefined symbols for architecture x86_64:
"_glfwCreateWindow", referenced from:
  _main in main-ba7a57.o
"_glfwInit", referenced from:
  _main in main-ba7a57.o
"_glfwMakeContextCurrent", referenced from:
  _main in main-ba7a57.o
"_glfwTerminate", referenced from:
  _main in main-ba7a57.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

程序是：

#define GLEW_STATIC
#include <glew.h>
#include <glfw3.h>
#include <iostream>
using namespace std;
int main(int argc, char* argv[]) {
GLFWwindow* window;
if(!glfwInit()) exit(EXIT_FAILURE);
window = glfwCreateWindow(1024, 768, "glfw", NULL, NULL);
if(!window) {
    glfwTerminate();
    exit(EXIT_FAILURE);
}
glfwMakeContextCurrent(window);
const GLubyte* version = glGetString(GL_VERSION);
cout << "OpenGL version: " << version << endl;
glfwTerminate();
return 0;
}
