title: Missing symbol on libQt5Dbus.so.5?
body: <p>I have a python application that uses <code>QT5</code>.</p>
  
  <p>I'm generating a binary for this app with <code>pyinstaller</code> (so that all the dependencies are bundled). This app is built from a <code>Centos6.8</code> docker instance (for compatibility reasons) with a patched-in <code>GLIBC</code> that <code>QT5</code> needs.</p>
  
  <p>When I run the application it fails with the bundled <code>libQt5Dbus.so.5</code> not having the symbol <code>dbus_connection_can_send_type</code>:</p>
  
  <pre><code>symbol lookup error: /tmp/_MEIyxSbsB/libQt5DBus.so.5: undefined symbol: dbus_connection_can_send_type
  </code></pre>
  
  <p>When I do <code>nm -D /path/to/libQt5Dbus.so.5</code> on the <code>Centos6.8</code> docker instance doesn't show the symbol I need (<code>dbus_connection_can_send_type</code>).</p>
  
  <p>What can I do to get the symbol in a <code>libQt5Dbus.so.5</code>?</p>
  
  <p>EDIT:
  I have found that one of the <code>libQt5Dbus.so.5</code> library in my system does actually have <code>dbus_connection_can_send_type</code> symbol. I've replaced all <code>libQt5Dbus.so.5</code> libraries with the one that does have the symbol and I still get the error.</p>
