@Alex108306 Hello, I am having the same problem. Could you share how you solved the problem?

[nanaminh]

For anyone looking for the solution later, here's how I solved the problem:

In additional_topic_subscriber.h, line 63,
change
class _AdditionalTopicSubscriber: QObject
to
class _AdditionalTopicSubscriber: public QObject
