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:

Quote:

---

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):

Code:

---

#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:

Code:

---

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:

Code:

---

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

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
