erreur de compilation asio async avec les fonctions asynchrones

Question

Je veux créer un asynchrone. serveur. Je réussis à le faire, mais maintenant je veux lier les fonctions async_read/asyn_write à la fonction d'objet appelant. Donc, j'ai essayé de le faire avec la fonction boost :: ici vous avez mon 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 et 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(); 
} 

et Network.cpp et .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))); 
}

Après tant d'heures de "googlings" et de réflexion, je n'ai pas trouvé pourquoi j'ai ces erreurs. Tout le monde peut m'aider plz?

Answer 1

En Network.h, ne comprennent pas Client.h, mais à la place forward declareclass Client.

Answer 2

Mmm .. Peut-être que vous les avez laissés, mais vous pas inclure les en-têtes:

Modifier Cela semble évident. Si ce n'est pas le cas
Editer 2 Notez que ces suggestions ont été tapées lorsque des informations complètes sur la structure include n'ont pas été fournies. Les problèmes ont été résolus maintenant, mais ces conseils sont bons conseils de dépannage général chaque fois que des problèmes étranges surgissent avec le compilateur ne « voir » vos déclarations:

• contrôle précompilés paramètres d'en-tête (les désactiver, par exemple)

• contrôle vous-tête pour les inclusions (si elles sont incorrectes, par exemple

  #ifndef __NETWORK_H 
  #define __NETWORK_H 
  
  ... 
  #endif // __NETWORK_H 
  

  dans votre Client.h ...

• vérifier que les problèmes namespace

  • accidentellement déclaré réseau dans un espace de noms
  • inclus Network.h à partir d'un namespace { ... } bloc

• vérifier les questions de préprocesseur (#define s de ravages semant?)

Server. cpp

include "Network.h" 
include "Server.h" 

//.... 

Client.cpp

include "Network.h" 
include "Server.h" 

réseau.cpp

include "Network.h" 

Et probablement (forme regardant les erreurs):

Client.h

include "Network.h"
