Undefined symbols within in PyQt4

  • Whenever I try to run a Qt program, such as this one:

    import sys
    from PyQt4.QtGui import *
    app = QApplication(sys.argv)
    button = QPushButton("Hello World", None)

    I get the following error message:

    from PyQt4.QtGui import *
    ImportError: /usr/lib/python2.7/dist-packages/PyQt4/ undefined symbol: _ZN15QSessionManager16staticMetaObjectE

    I have reinstalled the following packages to no avail:


    Some system info:
    Ubuntu 14.04.1 LTS
    usr/bin/python2.7: Python 2.7.6
    Using Qt version 4.8.6

    Hope anyone can help me with this.

  • I had same problem with QT5. The problem appears to be a version mismatch. After downloading a .deb at my problem was resolved.
