[PyKDE] Re: embedding python widgets in C++ app

[Patrick Stinson]

ok, removing all instances of "PyQt4." from the cpp, and without
modifying the sip files, I get this error for
PyRun_SimpleString("import QtCore; print QtCore"):

SystemError: _PyImport_FixupExtension: module QtCore not loaded

and this error for PyRun_SimpleString("import QtGui; print QtGui"):

ImportError: No module named PyQt4.QtCore

After changing the module names in the sip files and recompiling the
PyQt4 static libs it seems to work. I That means that the PyQt4
package definately gets in the way.

So this looks fine except everyone on our team has to do this
everytime they download a new version. Ideas?
