[Development] QMetaType::registerType: Binary compatibility break -- Size mismatch for type 'QPaintBufferCacheEntry' [1024]. Previously registered size 0, now registering size 16. Aborted (core dumped)

[Zhang Qun]

Dear all

I manage to compile my code with Qt 5 but when I run the program and
encountered the following error:

  QMetaType::registerType: Binary compatibility break -- Size mismatch for
type 'QPaintBufferCacheEntry' [1024]. Previously registered size 0, now
registering size 16.
Aborted (core dumped)
 I have googled for a few days and did not find any luck. Anyone could help
me with this? Thanks in advance. I am running Qt5 on ubuntu 14.04 64bit.

The source code is simple from sample code of the marble library (a globe
map library):

 Qt Code:
Switch view


   1. #include <QtWidgets/QApplication>
   2. #include <marble/MarbleWidget.h>
   3.
   4. int main(int argc, char** argv)
   5. {
   6.     QApplication
<http://qt-project.org/doc/qt-4.8/qapplication.html> app(argc, argv);
   7.
   8.     // Load Marble using OpenStreetMap in Mercator projection
   9.     Marble::MarbleWidget *mapWidget = new Marble::MarbleWidget;
   10.     mapWidget->setProjection(Marble::Mercator);
   11.     mapWidget->setMapThemeId("earth/openstreetmap/openstreetmap.dgml");
   12.
   13.     mapWidget->setWindowTitle("Hello Marble!");
   14.     mapWidget->show();
   15.     return app.exec();
   16. }

My cmake file to build is below:
Qt Code:
Switch view


   1. CMAKE_MINIMUM_REQUIRED (VERSION 2.8.11)
   2. SET (TARGET hello-marble)
   3. PROJECT (${TARGET})
   4.
   5. # Find includes in corresponding build directories
   6. set(CMAKE_INCLUDE_CURRENT_DIR ON)
   7. # Instruct CMake to run moc automatically when needed.
   8. set(CMAKE_AUTOMOC ON)
   9.
   10. # Find the Qt modules library
   11. find_package(Qt5Widgets REQUIRED)
   12.
   13. SET (QT_LIBRARIES ${QT_LIBRARIES} Qt5::Widgets)
   14. SET (MARBLE_LIBRARIES ${MARBLE_LIBRARIES} marblewidget)
   15. SET (LIBS ${LIBS} ${MARBLE_LIBRARIES} ${QT_LIBRARIES})
   16.
   17. ADD_EXECUTABLE (${TARGET} marble_test.cpp)
   18. TARGET_LINK_LIBRARIES (${TARGET} ${LIBS})

The gdb traceback of my program is:
