非同期を作成したい。サーバ。私はそれを成功させましたが、今は async_read/asyn_write 関数を呼び出し元オブジェクト関数にバインドしたいと考えています。だから私はboost::functionでそれをやろうとしましたここに私のコードがあります:

サーバー.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 および .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();
}

および Network.cpp および .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)));
}

それをコンパイルしたいとき、次のエラーがあります:

何時間もの「グーグル」と反射の後、なぜこれらのエラーが発生するのかわかりませんでした。誰でも私を助けてくれますか?

うーん..多分あなたはそれらを省略しましたが、ヘッダーを含めることができませんでした:

編集 2 これらの提案は、インクルード構造に関する完全な情報が提供されていないときに入力されたことに注意してください。問題は現在解決されていますが、これらのヒントは、コンパイラが宣言を「認識」しないという奇妙な問題が発生した場合の一般的なトラブルシューティングのアドバイスとして役立ちます。

  • プリコンパイル済みヘッダーの設定を確認します (無効にするなど)
  • ヘッダーにガードが含まれていることを確認してください(間違っている場合、たとえば

    #ifndef __NETWORK_H
    #define __NETWORK_H

  • 名前空間の問題を確認する

    • 名前空間で Network を誤って宣言しました
    • namespace { ... }ブロック内から Network.h をインクルード
  • プリプロセッサ#defineの問題をチェックします (大混乱を引き起こしていますか?)

サーバー.cpp

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

//....

クライアント.cpp

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

ネットワーク.cpp

include "Network.h"

そしておそらく(エラーを見てフォーム):

Client.h

include "Network.h"

Network.h では、Client.h をインクルードせず、代わりに前方宣言し class Clientます。
