[PyKDE] sip/PyQt compiling problems

Sun Sep 17 18:51:30 BST 2000

I wrote some programs in PyKDE, a while ago, but due to crashes etc. I lost 
the configuration and now I am trying to compile ANY version of PyKDE that 
works, but have so far been unsuccessful. It appears to be next to impossible 
to find any version of PyQT/PyKDE to match with any version of Qt/KDE that 
runs.

So far I have tried PyQt etc. 2.0, with version 1.44, 1.45, 2.02 of QT, and 
none works. The nearest I get with qt-1.44 and kde-1.1.2, and PyKDE-0.12, but 
that combo gives a QT run-time error when the python program is executed. The 
.rpm-files that I have found, gives undefined symbols when loaded. Which one 
is varying with which version of qt/qt I use.

As I supposed old version of PyQT/KDE is not supported, I have tried with 
version 2.0. This is what I get when trying to compile PyQt with Qt-2.2.0 
(the version of qt, is the one with the latest KDE 2.0 cvs snapshot):

If I instead try to compile with qt-1.44, I don't even get so far, but get 
the following compilation error, when trying to compile sip:

If I try with version 0.10 or 0.12 of PyQt/PyKDE, they compile with Qt-1.44 
and KDE 1.1.2, or even try the precompiled .rpm files, I instead get a 
run-time error:

cript started on Sun Sep 17 16:08:44 2000
[~/tut (4)]$ python p2.py
QObject: Object QSocketNotifier::unnamed has no meta object
Segmentation fault
[~/tut (4)]$ cat p2.py
import sys
from kdeui import *
from kdecore import *
from qt import *

a = KApplication(sys.argv, "p2")
hello = QPushButton(i18n("Hello World!"))
hello.setAutoResize(1)
a.setMainWidget(hello)
hello.show()
a.exec_loop()

The error comes on "KApplication"

If I used precompiled sip/PyQt/PyKDE in rpm-files, version 0.10, the following 
happens:

[~/tut (4)]$ python p2.py
Traceback (innermost last):
  File "p2.py", line 2, in ?
    from kdeui import *
  File "/usr/lib/python1.5/kdeui.py", line 5, in ?
    import libqtc
ImportError: /usr/lib/libsip.so.1: undefined symbol: __pure_virtual

So my question is actually: how can I find a working PyKDE/KDE combination, 
or in worst case a working PyQt/Qt combination. Which versions of respective 
software fit together? Or is there any version of PyQt/PyKDE that fits with 
any version of Qt/KDE?
I am running a debian based Linux, if it makes any difference.
