How to connect to tcp server via raw sockets in Linux using Qt?

Question

Qt

Hello! You need to write a client to communicate with a tcp server. I use raw sockets, because the standard qt's sockets did not want to start on the computer where the program will be used.
The whole project is written in Qt, only networking is in raw sockets.
I use this page as an example of working with raw sockets :
everything would be fine, but Qt swears at this line:

//Connect to remote server
        if (  connect(socket_desc , (struct sockaddr *)&server , sizeof(server)) < 0)

Qt uses connect to connect slots and signals... The
question is how to connect in Linux via raw sockets to a tcp server using Qt?

Answer 1

if (  ::connect(socket_desc , (struct sockaddr *)&server , sizeof(server)) < 0)
