title: downloading and using gmp Xcode 4.4
body: <p>I have seen other questions relating to this but I'm having trouble with the basics. My computer and programming knowledge is very limited, please bear with me.</p>
  
  <p>I am using Xcode4.4 for c++ on a MacBook Pro and I'm trying to use the gmp library. I have gone to the gmp site:  <a href="http://gmplib.org" rel="nofollow">http://gmplib.org</a> and have clicked on the download gmp-5.1.tar.lz but what is downloaded seems very cryptic and I'm not sure on how to proceed. I know that once you've got the library on your computer you can then link it into your project and use header files to use the library. I am also not sure how to do this.</p>
  
  <p>Could anyone walk me through the process of downloading the gmp library and then using it in a c++ project on Xcode? </p>
  
  <p>Any other comments/advice on this would also be great.</p>
  
  <p>Thanks.</p>
