Yes, I sure did. Since my first post I've been looking
at a working install on my other machine but it uses a
version of libqt-mt.so that I compiled from source.
The first problem with my Mandrake 9.1 install is, as
everyone seems to know now, it only supports the SGI
style as a plugin. Doing an objdump -T on the working
version of libqt-mt.so shows the presence of the
undefined symbol that is causing a problem when I try
to import qt in the python interpreter
(_ZNK9QSGIStyle9classNameEv).

That is why it seems necessary to add the #define
QT_NO_STYLE_SGI 1 directive in qconfig.h (yes, I
mistakenly referred to it as qtconfig.h in my previous
post). After adding that line, I went right back to
the start and made and installed sip. I am able to run
the build script in the PyQT source dir but as soon as
I try to make the libraries I get a series of compile
errors beginning with:

g++ -c -pipe -w -O2 -fomit-frame-pointer -pipe
-march=i586 -mcpu=pentiumpro -D_REENTRANT -fPIC 
-DSIP_MAKE_MODULE_DLL -DQT_NO_DEBUG
-DQT_THREAD_SUPPORT -I/usr/lib/qt3/mkspecs/default -I.
-I. -I/usr/include/python2.2 -I/usr/lib/qt3/include -o
qtcmodule.o qtcmodule.cpp
In file included from qtcmodule.cpp:195:
sipqtQSGIStyle.h:50: parse error before `{' token
sipqtQSGIStyle.h:53: destructors must be member
functions
sipqtQSGIStyle.h:57: non-member function `QVariant
property(const char*)' cannot have `const' method
qualifier
sipqtQSGIStyle.h:64: non-member function `QPixmap
stylePixmap(QStyle::StylePixmap, const QWidget*, const
QStyleOption&)' cannot have `const' method qualifier

This is why, as an experiment and no doubt unwisely
(sorry to mess with your work Phil), I then went into
$PYQTDIR/qt and modified qtcmodule.cpp by adding some
#ifndef QT_NO_STYLE_SGI tests around the relevant SGI
style related code. This let me make the PyQt wrapper
libraries but resulted in  a different undefined
symbol error (related to the QSettings class -
_Z16sipNew_QSettingsP7_objectS0_). Looking at the
dependencies of libqtcmodule.so gave me this:

(0x412ed000)

Now I don't know too much about the linking stage, but
the fact that "libsip.so.9 => not found" appears seems
rather concerning. Why would this be happening?

Thanks again,

Damien
