title: Using QJson library in Qt Creator under Ubuntu
body: <p>I'm trying to use the QJson library in an application that is being created in Qt Creator .  The operating sytsem is Ubuntu 12.04 32-bit.</p>
  
  <p>I used synaptic to install libqjson0 (0.7.1-6). The libary was installed in </p>
  
  <pre><code>/usr/lib/i386-linux-gnu/libqjson.so.0
  /usr/lib/i386-linux-gnu/libqjson.so.0.7.1
  </code></pre>
  
  <p>I tried to add the library to Qt Creator by right clicking my project and selecting 'Add Library..'.  When I entered either of the 2 paths shown above, the filename was in red indicating that it wasn't correct.  I created a symlink <strong>libqjson.so</strong> that links to libqjson.so.0.7.1.  I was able to add the library now using the /usr/lib/i386-linux-gnu/libqjson.so path.</p>
  
  <p>Now for the noob question:  At the top of the app I added #include &lt;parser.h&gt;.  I get an error 'parser.h: No such file or directory.  I searched /usr/libs/i386-linux-gnu for parser.h and it didn't return any results.  Do I need to add something/ before parser.h or am I missing something else?</p>
