qobject_cast fails across dynamic library boundaries

[wysota]

Could you show us how exactly did you try to use qobject_cast? What does this return when called in both DLLs?

qDebug() << "I am a " << MatrixReal::staticMetaObject().className();
const QMetaObject *mo = MatrixReal::staticMetaObject().superClass();
while(mo){
  qDebug() << "It's superClass is" << mo->className();
  mo = mo->superClass();
}

qDebug() << "I am a " << MatrixReal::staticMetaObject().className();
const QMetaObject *mo = MatrixReal::staticMetaObject().superClass();
while(mo){
  qDebug() << "It's superClass is" << mo->className();
  mo = mo->superClass();
}

I didn't see your question thread, so I've described the reason and solution of your (my ) problem in separate thread..
