boost asio compilation error with async functions - c++

Question

I want to create an async. server.
i succeed to do that, but now i want to bind async_read/asyn_write functions to caller object function. So i tried to do that with boost::function
here you have my code :
Server.cpp
#include "Server.h"
#include "Client.h"
#include "Network.h"
void Server::accept(void)
{
Network::ptr connection = Network::create(this->my_acceptor.get_io_service());
this->my_acceptor.async_accept(connection->getSocket(), bind(&Server::endCmd, this, connection, placeholders::error));
}
void Server::endCmd(Network::ptr connection, const boost::system::error_code& error)
{
if (!error)
{
std::cout << "Recu un client!" << std::endl;
this->client.push_back(new Client(connection));
this->client[client.size() - 1]->checkAuthentification();
std::cout << "Envoie du message de securisation" << std::endl;
std::cout << "Nouvelle ecoute" << std::endl;
this->accept();
}
}
Client.h and .cpp
#include "Network.h"
class Client
{
private:
Network::ptr connection;
public:
Client(Network::ptr);
~Client();
void checkAuthentification(void);
void endRead(const error_code& error, size_t nbytes);
void endWrite(const error_code &error);
};
#include "Client.h"
Client::Client(Network::ptr connect)
{
this->connection = connect;
this->connection->assignFunction(this);
}
Client::~Client()
{
this->connection->close();
}
void Client::checkAuthentification(void)
{
this->connection->Swrite("BIENVENUE", this);
}
void Client::endRead(const error_code& error, size_t nbytes)
{
if (!error && nbytes != 0)
{
std::cout << this->connection->getRcvMsg() << std::endl;
this->connection->Sread(this);
}
else
this->connection->close();
}
void Client::endWrite(const error_code &error)
{
if (!error)
this->connection->Sread(this);
else
this->connection->close();
}
and Network.cpp and .h
#include "Client.h"
class Network : public boost::enable_shared_from_this<Network>
{
private:
tcp::socket socket;
std::string rcv_msg;
std::string msg;
boost::array<char, 6> rbuffer;
boost::function<void (Client *, const error_code &, size_t)> fread;
boost::function<void (Client *, const error_code &)> fwrite;
public:
typedef boost::shared_ptr<Network> ptr;
Network(io_service &);
~Network();
void assignFunction(void);
void close(void);
void Sread(Client *cli);
void Swrite(std::string msg, Client *cli);
tcp::socket& getSocket(void);
std::string getRcvMsg(void);
static ptr create(io_service &);
};
#include "Client.h"
#include "Network.h"
Network::Network(io_service &ios) : socket(ios)
{
}
Network::~Network()
{
this->close();
}
void Network::assignFunction(void)
{
this->fread = &Client::endRead;
this->fwrite = &Client::endWrite;
}
void Network::close(void)
{
if (this->socket.is_open())
{
std::cout << "Connection closed" << std::endl;
this->socket.close();
}
}
void Network::Sread(Client *cli)
{
async_read(this->socket, buffer(this->rbuffer), bind(&Network::fread, cli, placeholders::error, placeholders::bytes_transferred));
}
void Network::Swrite(std::string msg, Client *cli)
{
this->msg = msg;
async_write(this->socket, buffer(this->msg, (int)this->msg.size()), bind(&Network::fwrite, cli, placeholders::error));
}
std::string Network::getRcvMsg(void)
{
return (std::string(this->rbuffer.c_array(), this->rbuffer.size()));
}
tcp::socket& Network::getSocket(void)
{
return (this->socket);
}
Network::ptr Network::create(io_service &ios)
{
return (ptr(new Network(ios)));
}
When i want to compile that, i have the following errors :

After so many hours of "googlings" and reflexion, i didn't found why i have these errors.
Anyone can help me plz ?

Answer 1

Mmm.. Maybe you have left them out but you failed to include the headers:
Edit That seems to obvious. If it's not that then
Edit 2 Note that these suggestions have been typed when full information about the include structure wasn't given. The problems has been resolved now, but these hints are good general troubleshooting advice whenever strange issues arise with the compiler not 'seeing' your declarations:
check precompiled header settings (disable them, e.g.)
check you header include guards (if they are incorrect, e.g.
#ifndef __NETWORK_H
#define __NETWORK_H
...
#endif // __NETWORK_H
in your Client.h...
check namespace issues
accidentally declared Network in a namespace
included Network.h from within a namespace { ... } block
check preprocessor issues (#defines wreaking havoc?)
Server.cpp
include "Network.h"
include "Server.h"
//....
Client.cpp
include "Network.h"
include "Server.h"
Network.cpp
include "Network.h"
And probably (form looking at the errors):
Client.h
include "Network.h"
too

Answer 2

In Network.h, do not include Client.h, but instead forward declare class Client.
