title: How to install gcc in Mac OS X Lion
body: <p>I am new in mac os. I have one Mac book pro. I am looking for gcc in my Mac. I already install XCode. So, C++ library already installed with XCode. But, I can not use it from outside XCode. I want to use c++ library with Eclipse. I do not know how to configure it with eclipse or how to install gcc, if I already have XCode? Should I use any other library?</p>
  
  <p>Hints: </p>
  
  <p>When I write following command in my terminal it shows an error.</p>
  
  <pre><code>$ gcc -v
  -bash: gcc: command not found
  $
  </code></pre>
  
  <p>Thanks, in advance.</p>
