Kdevplatform /usr/lib64/libQtWebKit.so.4: undefined reference to `g_mutex_lock'

[Michael Hart]

The OS is openSuSE 11.4 with update of everything having to do with an
uptate of QT 4.8.x from QT 4.7.x (in the standard 11.4) The compiler I used
in both case was gcc 4.5

Now that I have managed to bring my system back to the standard openSuSE
11.4 (with the latest greatest standard updates) the building issue has
gone away. So, there is nothing I can to test your ideas and I definitely
do not want to go back to the issues I was having for the past few days.

I am a big proponent and user of  of Kdevelop4 at home and at work. When it
broke because of some casual update to QT 4.8.x on my systems it really
cost me a lot of lost time both at home and work

But again, thanks for giving me some ideas should this type of think every
occurs again
