qextserialport crashes prigramm

M_Big

Hi, everybody!
I'm using qextserialport in my win app. It has 4 header and cpp files.

    3dparty/qextserialport/qextserialenumerator_unix.cpp \
    3dparty/qextserialport/qextserialenumerator_win.cpp \
    3dparty/qextserialport/qextserialport.cpp \
    3dparty/qextserialport/win_qextserialport.cpp

    3dparty/qextserialport/qextserialenumerator.h \
    3dparty/qextserialport/qextserialport.h \
    3dparty/qextserialport/qextserialport_global.h \
    3dparty/qextserialport/qwineventnotifier_p.h

When I include this lib to empty Qwidget project. Project doesn't run. It says "The program has unexpectedly finished." When I execute project without this lib, it's ok.
I found out, if I comment out some lines in moc_qwineventnotifier_p.cpp:

QT_INIT_METAOBJECT const QMetaObject QWinEventNotifier::staticMetaObject = { {
   /* &QObject::staticMetaObject,
    qt_meta_stringdata_QWinEventNotifier.data,
    qt_meta_data_QWinEventNotifier,
    qt_static_metacall,
    nullptr,
    nullptr */
} };

It would work. But I don't know why. Can someone explain what's going on? Why this lines affect on execution. Some theoretical help pls.

qwineventnotifier_p.h is a private header of Qt Core. Having a copy of it in your app is calling for problems, especially if the version of it doesn't match the exact version that Qt Core is built with.

I assume qextserialport needs access to this private header; in this case, make sure that private headers are installed, and try to include the header from Qt.
