title: extending default lib search path in ubuntu
body: <p>How can i extend default lib search path in ubuntu(in a way that it is also persistent) ? no, I do <strong>not</strong> want export LD_LIBRARY_PATH based temporary solution, rather some way to extend the default lib search path ?</p>
  
  <p>while google-ing, I cam across some info, that in ubuntu the default search path resides in <em>/etc/ld.so.conf.d</em> , but editing libc.conf does not extended the default path.. so i think either i am doing it wrong, or something is missing...</p>
  
  <p>the edited <em>libc.conf</em> looks like... </p>
  
  <pre><code># libc default configuration
  /usr/local/lib:/path_to_my_libraries/lib
  </code></pre>
