c++ - Boost 突然进入我的命名空间，声称缺少函数的错误

Question

在“Me vs Boost、libconfig、protocol buffers 和 glog”传奇的这一新情节中，我们发现我们的主角(我)正在为命名空间的所有权而与 Boost 进行殊死的战斗!

好吧，我一直在使用这个漂亮的代码:

服务器.h

#ifndef SERVER_H
#define SERVER_H 1

#include "configuration.h"
#include "client.h"
#include "client_manager.h"
#include <string>
#include <boost/noncopyable.hpp>
#include <boost/asio.hpp>
#include <boost/thread.hpp>
#include <boost/shared_ptr.hpp>
#include <boost/bind.hpp>

namespace BBCP {
    namespace Server {

class Server : private boost::noncopyable {
public:
    Server(BBCP::App::Config const &wrapper) :
        acceptor(io_service),
        wrapper(wrapper)
        //signals(io_service),
        { }
    void run();
protected:
    void acceptHandler(boost::system::error_code const &error);
    void startAccept();
    void stopServer();
private:
    boost::asio::io_service io_service;
    boost::asio::ip::tcp::acceptor acceptor;
    boost::asio::ip::tcp::endpoint endpoint;
    //boost::asio::signal_set signals;

    BBCP::Server::client_ptr newClient;
    BBCP::Server::ClientManager manager;

    boost::thread_group client_pool;
    BBCP::App::Config wrapper;
};

    }
}

#endif

对于现在的几个构建，它运行良好，直到之后......好吧，什么都没有，它开始出错:

In file included from /usr/include/boost/type_traits/has_nothrow_constructor.hpp:12:0,
                 from /usr/include/boost/optional/optional.hpp:25,
                 from /usr/include/boost/optional.hpp:15,
                 from /usr/include/boost/thread/pthread/thread_data.hpp:13,
                 from /usr/include/boost/thread/thread.hpp:17,
                 from /usr/include/boost/thread.hpp:13,
                 from ../include/server.h:10,
                 from main.cpp:17:
/usr/include/boost/type_traits/has_trivial_constructor.hpp:36:1: error: ‘has_trivial_ctor_impl’ is not a member of ‘boost::detail’
/usr/include/boost/type_traits/has_trivial_constructor.hpp:36:1: note: suggested alternative:
/usr/include/boost/type_traits/has_trivial_constructor.hpp:25:8: note:   ‘BBCP::Server::boost::detail::has_trivial_ctor_impl’

(...) This goes on and on with a lot of dependencies.

现在，据我所知，BBCP::Server::boost::detail::has_trivial_ctor_impl 指的是 boost::detail 中定义的某个方法。重点是，boost::detail 不应该进入我的命名空间，BBCP::Server!

老实说，我看不出这个错误是从哪里来的，所以...

任何帮助将不胜感激!

可能是您之前包含的其中一个 header 中的一个错误，它没有正确关闭命名空间。
