Ошибка в проекте C++ eclipse с использованием библиотек Boost

Question

У меня возникают некоторые проблемы при компиляции проекта C++ в Eclipse. Он работает хорошо, но когда я заголовочный файл подталкивание (алгоритм/string.hpp) он показывает мне theese ошибки:

И когда я использую другую библиотеку (iostream, вектор, строка, fstream ...), он говорит, что Eclipse не смог найти эту библиотеку, но если я скомпилирую ее без заголовка boost, это сработает. Это мой код:

//============================================================================ 
// Name  : Emulator.cpp 
// Author  : Manulaiko 
// Version  : 1.0 
// Description : SpaceBattles' emulator main file 
//============================================================================ 

#include <iostream> 
#include <fstream> 
#include <string> 
#include <vector> 
#include "/root/boost/boost/algorithm/string.hpp" 

using namespace std; 

void loadConfig() 
{ 
    ifstream file("settings"); 
    string s; 

    while(getline(file, s)) { 
     vector<string> line; 
     boost::split(line, s,"="); 

     //Test 
     cout << line[0] << " = " << line[1] << endl; 
    } 
} 

void connect() 
{ 

} 

int main() { 
    cout << "SpaceBattles C++ emulator 1.0 by Manulaiko" << endl; 
    cout << endl; 

    cout << "Reading settings file..." << endl; 
    loadConfig(); 

    cout << "Establishing connection to MySQL..." << endl; 
    connect(); 
}

Третьи пары в boost::split() должны быть функция (или «отозван»), а не строка. Попробуйте

boost::split(line, s, boost::is_any_of("=")); 

is_any_of() на самом деле конструктор, но он создает объект, который может быть назван как функция.

Существует, вероятно, что-то лучше, чем is_any_of (то есть что-то вроде is_equal), но я вытащил его прямо из документации: http://www.boost.org/doc/libs/1_56_0/doc/html/string_algo/usage.html#idp432343152
