Qmetatype::registertype:binary compatibility break-size mismatch for type ' qpaintbuffercacheentry ' [1024]. Previously registered size 0, now Regist

It is found that this problem is related to the dependency of OpenCV, and the problem mainly arises in the version of the relationship between the installed OpenCV and Qt4, Qt5. It should be OpenCV Lib compile-time dependent on QT4. And my project needs to rely on QT5.

such as: my problem is solved. This is happened because I used OpenCV libs in my project and compiled it with QT4. I rebuild OpenCV with QT5 and now everything are OK.

Solve:

1. Set QT5 as the default library: reference: http://blog.csdn.net/zyh821351004/article/details/43273763

         sudo apt-get install qt5-default

2. Recompile OpenCV: (Want to quickly, remember to turn example off)

3. Recompile the original project. Ok.
