title: Qt for Embedded Linux data directory is not owned by user 0: /tmp/qtembedded-0
body: <p>Okay so I'm very new at all of this so please forgive me if I don't provide enough information but feel free to ask for more.</p>
  
  <p>I had to install ParaView from source on my linux system. ParaView requires Qt to be installed to be able to compile and install it. So I installed Qt on my linux system from source as well (version 4.8.6 to be precise). My ParaView is now installed but I can't seem to run it. The first time I tried I got the following output:</p>
  
  <pre><code>QWSSocket::connectToLocalFile could not connect:: Connection refused
  QWSSocket::connectToLocalFile could not connect:: Connection refused
  QWSSocket::connectToLocalFile could not connect:: Connection refused
  QWSSocket::connectToLocalFile could not connect:: Connection refused
  QWSSocket::connectToLocalFile could not connect:: Connection refused
  QWSSocket::connectToLocalFile could not connect:: Connection refused
  No Qt for Embedded Linux server appears to be running.
  If you want to run this program as a server,
  add the "-qws" command-line option.
  </code></pre>
  
  <p>When I ran it as sudo, I got the following output:</p>
  
  <pre><code>Qt for Embedded Linux data directory is not owned by user 0:  /tmp/qtembedded-0
  </code></pre>
  
  <p>I have no idea what this means or how to fix it, any help will be much appreciated.</p>
  
  <p>Extra info: I installed ParaView version 4.4</p>
  
  <p>my Qt dir is /usr/local/Trolltech/QtEmbedded-4.8.6/bin</p>
  
  <p>my ParaView dir is /usr/local/bin</p>
  
  <p>I couldn't find anything on google or on here and that's why I'm asking.</p>
