title: Installing boost library in /usr/lib: sudo ./boostrap.sh command not found
body: <p>I am trying to install the Boost C++ libraries using <a href="http://www.boost.org/doc/libs/1_45_0/more/getting_started/unix-variants.html#easy-build-and-install" rel="nofollow">these instructions</a>. This is using Ubuntu 10.10. I have unzipped the .zip file in <code>/usr/lib</code>, and cd'd to the <code>boost_1_45_0</code> folder. I then run:</p>
  
  <pre><code>sudo ./boostrap.sh --help
  </code></pre>
  
  <p>And I get the following error:</p>
  
  <pre><code>sudo: ./bootstrap.sh: command not found
  </code></pre>
  
  <p>I don't understand why this is, as <code>bootstrap.sh</code> is clearly there in the current folder.</p>
  
  <p>Is this because of the location I am installing to, or is it perhaps a command within bootstrap.sh that can't be found? It is a clean Ubuntu install so I am unsure as to why I am getting an error when following instructions so precisely.</p>
