使用异步函数提升asio编译错误

我想创建一个异步。服务器。我成功地做到了这一点，但现在我想将async_read/asyn_write函数绑定到调用者对象函数。所以我试图做到这一点与升压::功能在这里你有我的代码：使用异步函数提升asio编译错误

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和.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(); 
}

和Network.cpp和.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))); 
}

当我想编译时，我有以下错误：

经过这么多小时的“googlings”和反思，我没有找到为什么我有这些错误。任何人都可以帮助我吗？

在Network.h，不包括Client.h，但而不是forward declareclass Client。

是的，它的工作，我删除了#include“Client.h”并添加了“客户端类”。我还有其他错误，但我会尽力单独解决这些问题。谢谢 –

没问题，很高兴我能帮到你。 –

嗯..也许你已经离开了出来，但你没有包括标题：

编辑这似乎是显而易见的。如果不是那么
编辑2请注意，这些建议是在没有给出有关包含结构的完整信息时输入的。该问题已经得到解决，但这些提示是好的一般故障排除建议每当奇怪的问题与编译器不“看到”你的声明出现：

检查编译头设置（禁用它们，例如）
检查你接头，包括警卫（如果它们不正确，如
```
#ifndef __NETWORK_H 
#define __NETWORK_H 

... 
#endif // __NETWORK_H 
```
在Client.h
...
检查的名称空间问题
- 在命名空间
- 包括Network.h从namespace { ... }块
检查预处理器的问题（#define小号肆虐？）

Server中意外宣布网络。 cpp

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

//....

Client.cpp

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

网络。CPP

include "Network.h"

，可能（形式看错误）：

Client.h

include "Network.h"

太

不，不，我删除它显示我的代码 –

现在增加了更多的想法。顺便说一下，既然你删除了它们，那么我们真的没有什么可以看到的。正如你可能知道的那样，编译器不知道关于这些标识符的任何信息。这是非常重要的。 – sehe

我在我的主题上添加了所有包含的内容 –
