QWT 5, QT3, SuSE 10.2. Crash and burn

[wysota]

Did you recompile the application after the upgrade? What does the backtrace say?

Yeah, totally clean rebuild. All object files removed, qmake re-run etc

Um... I am not mixing QT4 and QT3 libraries here by mistake am I.... ?

[marcel]

Well, yes you are using Qt4 libraries: #9 0x00002adf2b62de4b in _init () from /usr/lib64/libQtCore.so.4.

You should be using the libs from /usr/lib/qt3/lib64/.

Make sure LD_LIBRARY_PATH contains /usr/lib/qt3/lib64/ before usr/lib64 and also make sure QTDIR points to the right qt installation.

OK, this looks like it may be the problem.
I have uninstalled QT4 and its many parts from the PC. I will rebuild QWT etc etc so that it no longer uses the QT4 libraries. Hopefully, this should fix the problem.

Thanks to you both.

[wysota]

It should be enough to rebuild qwt - without uninstalling Qt4.

[wysota]

Seems that you are.
