You did not use the correct syntax.

The compiler told you that the problem was that you did not select one of the 
overloads. QTcpSocket::error points to multiple functions and you need to 
select one only.

To do that, you need to cast the identifier to a specific signature.

    void (QAbstractSocket:: *sig)(QAbstractSocket::SocketError) =
	&QAbstractSocket::error;
    connect(tcp_socket, sig, this, &MyClass::tcpSocketError);
