           Summary: running marble example code with Qt5: Size mismatch

           Product: marble
           Version: unspecified
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal

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):

    #include <QtWidgets/QApplication>
    #include <marble/MarbleWidget.h>

    int main(int argc, char** argv)
    {
        QApplication app(argc, argv);

        // Load Marble using OpenStreetMap in Mercator projection
        Marble::MarbleWidget *mapWidget = new Marble::MarbleWidget;
        mapWidget->setProjection(Marble::Mercator);
        mapWidget->setMapThemeId("earth/openstreetmap/openstreetmap.dgml");

        mapWidget->setWindowTitle("Hello Marble!");
        mapWidget->show();
        return app.exec();
    }

My cmake file to build is below:

    CMAKE_MINIMUM_REQUIRED (VERSION 2.8.11)
    SET (TARGET hello-marble)
    PROJECT (${TARGET})

    # Find includes in corresponding build directories
    set(CMAKE_INCLUDE_CURRENT_DIR ON)
    # Instruct CMake to run moc automatically when needed.
    set(CMAKE_AUTOMOC ON)

    # Find the Qt modules library
    find_package(Qt5Widgets REQUIRED)

    SET (QT_LIBRARIES ${QT_LIBRARIES} Qt5::Widgets)
    SET (MARBLE_LIBRARIES ${MARBLE_LIBRARIES} marblewidget)
    SET (LIBS ${LIBS} ${MARBLE_LIBRARIES} ${QT_LIBRARIES})

    ADD_EXECUTABLE (${TARGET} marble_test.cpp)
    TARGET_LINK_LIBRARIES (${TARGET} ${LIBS})

My gdb traceback of my code is:
