<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have been using an Anaconda distro for Python 3.4. on RedHat 6.5<o:p></o:p></p>
<p class="MsoNormal">In order to write Qt5 compatible apps I built the appropriate SIP and PyQt5 modules.
<o:p></o:p></p>
<p class="MsoNormal">My PyQt5 libs are located in my ~/.local/lib/python3.4/lib/PyQt5 folder.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">All was good until Anaconda was re-installed. Now I get the following error when I run a python script that requires PyQt5 package:<o:p></o:p></p>
<p class="MsoNormal">“This application failed to start because it could not find or load the Qt platform plugin xcb”.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I also notice the same error for other workstations that have Anaconda newly installed.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Any clues as to why this is occurring?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">When I debug my script it succeeds in importing the packages, but dies when attempting to create a QApplication object.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I checked libqxcb has no missing dependents.<o:p></o:p></p>
<p class="MsoNormal">I rebuilt SIP and PyQt5<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Below is a code example:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">import sys<o:p></o:p></p>
<p class="MsoNormal">from PyQt5.QtWidgets import QApplication, QWidget<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">if __name__==’__main__’:<o:p></o:p></p>
<p class="MsoNormal"> app = QApplication(sys.argv)<o:p></o:p></p>
<p class="MsoNormal"> w = QWidget()<o:p></o:p></p>
<p class="MsoNormal"> w.show()<o:p></o:p></p>
<p class="MsoNormal"> sys.exit(app.exec_())<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Regards John<o:p></o:p></p>
