Exception while creating a socket

Question

I am using glibmm v2.42 on linux.

I want to create a client / server using native linux socket.

When trying to create a socket, an exception is always thrown with code 15 (not supported).

On the code below I looped over socket family enum, type enum and protocol enum but it always fails.

#include <iostream>
#include <glibmm.h>
#include <giomm.h>

int main(){
  Glib::init();
  Gio::init();

  std::vector<Gio::SocketFamily> fams = {Gio::SOCKET_FAMILY_UNIX , Gio::SOCKET_FAMILY_IPV4 , Gio::SOCKET_FAMILY_IPV6};
  std::vector<Gio::SocketType> types = {Gio::SOCKET_TYPE_STREAM, Gio::SOCKET_TYPE_DATAGRAM, Gio::SOCKET_TYPE_SEQPACKET };
  std::vector<Gio::SocketProtocol> protocols = {Gio::SOCKET_PROTOCOL_DEFAULT , Gio::SOCKET_PROTOCOL_TCP, Gio::SOCKET_PROTOCOL_UDP, Gio::SOCKET_PROTOCOL_SCTP };
   Glib::RefPtr<Gio::Cancellable> cancellable = Gio::Cancellable::create();

 for(int i = 0; i  < fams.size(); i++){
    for(int j = 0; j < types.size(); j++){
        for(int k= 0; k < protocols.size(); k++){

            Gio::SocketFamily fam = fams[i];
            Gio::SocketType type= types[j];
            Gio::SocketProtocol protocol = protocols[k];

            try {
               Glib::RefPtr<Gio::Socket> socket = Gio::Socket::create(fam , type, protocol , cancellable);
            } catch(const Gio::Error& e){
                std::cout << e.code() << std::endl;
            }
        }
     }
 }

 return 0;
}

Any ideas ? Does anyone have a working example of client/server with native linux socket using glibmm ?

Thanks for your help.

EDIT : In the code I removed the XXX and wrote the loops. This code returns 15 for all parameters configurations
