Although my error message was different, I think I had the same problem. PyQt
has been linked against an old version of Qt, to confirm this do
ldd /usr/lib/python2.1/site-packages/libqtcmodule.so ;
If you see a different version of Qt than what you thought you had linked
against, then you have the same problem. Although I had $QTDIR correct in the
shell I did ./configure ; make ; in I then did su ; make install ; and my
/root/.bashrc exported the wrong $QTDIR. Even after I had changed this no
amount of make uninstall ; make install ; would make things better.
Here is the list of things I did before I got things working.
1)Delete all PyQt and sip files from /usr/lib/python2.1/site-packages/
including eric/ .
2)If you have ever installed a version of sip less than 3.1 there will be
files in /usr/local/lib and /usr/local/include , get rid of these, there is
also a file in /usr/local/bin , I got rid of this as well, but it is not
mentioned in the sip README file.
3)The PyQt README file mentions version prior to 2.0, but I don't know where
4)chmod 000 the old version of Qt that was causing problems. Remember that
software using it wont work.
5)Delete the source trees of PyQt and sip, assuming you built in the source
tree, and create them again from the original .tar.gz files.
6)Start all over again but this time using ./configure --with-qt-dir=$QTDIR ;
for both sip and PyQT.
I doubt all of this was necessary, but PyQt takes such a long time to compile
I was taking no chances.
I hope this is usefull to you.
It would be good if someone could tell me at what point Qt is linked to, and
how it is decided which Qt to link to? I notice that make install ; uses
