подталкивания ошибки синхронного клиент

Question

Я новичок в повышении :: ASIO библиотеки, при попытке это основной синхронного клиента, его предоставлением этой ошибки

#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; 

int main() 
{ 

    io_service service; 
    ip::tcp::endpoint ep(ip::address::from_string("127.0.0.1"), 80); 
    ip::tcp::socket sock(service); 
    sock.connect(ep); 


} 

ошибки при компиляции,

обновление:

работает с

[root@kris server]# g++ -o test1 test1.cpp -lboost_system 

производит эту ошибку:

Answer 1

Вы должны добавить -lboost_system и -lpthread в командной строке g++, как это:

g++ -o test1 test1.cpp -lboost_system -lpthread 

Answer 2

Вы утверждаете, что используете все эти библиотеки, но ваша строка g++, похоже, не содержит их.

Вы должны сообщить компоновщику, какие файлы объектов и библиотеки он должен связывать вместе.
