A few of suggestions: - take this to the PyQt mailing list (http://www.riverbankcomputing.com/mailman/listinfo/pyqt) - you only *need* pyqt if what you want to do in python has really to deal with Qt-objects - maybe "simple" embedding is enough for your needs - I don't see why you need to compile PyQt yourself at all - are you sure you can't use the stock PyQt for windows? What makes you believe you really need this to be self-compiled? Diez -- http://mail.python.org/mailman/listinfo/python-list
