    Lightbulb QMetaType::registerType: Binary compatibility break -- Size mismatch for type 'QPaint

    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:
    1. #include <QtWidgets/QApplication>
    2. #include <marble/MarbleWidget.h>
    3.  
    4. int main(int argc, char** argv)
    5. {
    6. QApplication 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:
    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})

    My gdb traceback of my code is:

    Check the build output, maybe you are accidentally linking against an incompatible version of Marble, e.g. its Qt4 version.

    Cheers,

    Thanks anda

    I compiled marble with Qt4 instead and it worked. Maybe the marble now does not support Qt5.

    I am pretty sure it can be built with both Qt versions.
    Its CMakeList.txt file has sections for each version
