connect(m_pUdpSockRecv, &QAbstractSocket::error, this, &Udp::fnSocketError);get error:
error: no matching member function for call to 'connect'Do I need to add anything?

@w-tkm what version of Qt do you use ?
the error signal was deprecated and errorOccured was introduced.
This was made due to the fact that error is not only a signal but also a regular function of QAbstractSocket.to use an overload in the new connect syntax requires the use of complicated casting, or the use of the qOverload macro
