boost同步服务器客户端编译错误

标签: c++ linux

我正在尝试编译此代码,这是一个在boost :: asio库上编写的简单同步服务器..

#include <iostream>
#include <boost/asio.hpp>
#include <boost/bind.hpp>
#include <boost/thread.hpp>
#include <boost/shared_ptr.hpp>

using namespace std;


using namespace boost::asio;

typedef boost::shared_ptr<ip::tcp::socket> socket_ptr;

int main()
{

    io_service service;
    void client_session(socket_ptr sock);
    ip::tcp::endpoint ep( ip::address::from_string("127.0.0.1"), 2001);
    ip::tcp::acceptor acc(service, ep);
    while (true) {
        socket_ptr sock(new ip::tcp::socket(service));
        acc.accept(*sock);
        boost::thread(boost::bind(client_session,sock));
    }

}

void client_session(socket_ptr sock)
{
    while(true) {
        char data[512];
        size_t len = sock->read_some(buffer(data));
        if (len > 0)
            write(*sock, buffer("ok", 2));
    }
}
编译时出现

错误...

任何想法?

FIXED:

使用

    g ++ -o test2 test2.cpp -lboost_system -lpthread -lboost_thread-mt

答案 0 :(得分:0)

您应该链接到Boost.Thread库。添加-lboost_thread

注意:您可能有多线程版本。然后尝试-lboost_thread-mt
