Opencv and qt 5.1 integration [SOLVED]
-
Hi,
using opencv-2.4.6, Qt 5.1 on OpenSuse 12.2 64 bit, i run my software and i have:
QMetaType::registerType: Binary compatibility break -- Size mismatch for type 'QPaintBufferCacheEntry' [1024]. Previously registered size 0, now registering size 16.I tryed also with some example downloaded from internet and i have same error.
What's happen?

Hi,
You probably have OpenCV built with Qt 4 (check opencv_highgui with ldd) So you can't use it like this with Qt5, you should either rebuild OpenCV with Qt 5 (I don't know it its already possible) or rebuild it without Qt.
Hope it helps

I have also configured $PATH=/home/myhome/Qt5.1.1/5.1.1/gcc/bin:$PATH
