title: Header-only asio standalone
body: <p>Sorry in advance for a kind-of-dumb question - I'm pretty new to all this.</p>
  
  <p>So I downloaded asio from <a href="http://think-async.com/" rel="nofollow">here</a>, and tried to #include asio.hpp, but got the following error;</p>
  
  <pre><code>fatal error: boost/config.hpp: No such file or directory
  </code></pre>
  
  <p>I thought this was rather odd, as it was suppose to be independent of Boost. I poked around a bit, and saw that I needed to define ASIO_STANDALONE, which I promptly did, only to be met with more errors where it tried to #include something else from Boost.</p>
  
  <p>Is there just a big list of all the things I have to #define to tell it to be standalone or something? That would be very helpful.</p>
