我在ubuntu 10.04上安装了boost

sudo apt-get install libboost-dev

我想在那之后我不需要设置任何-I和-L标志,所以我编译我的代码

g++ test.cpp

这是我的test.cpp

#include <iostream>
#include <string>
#include <set>
#include <sstream>

#include <boost/config.hpp>
#include <boost/program_options/detail/config_file.hpp>
#include <boost/program_options/parsers.hpp>

namespace pod = boost::program_options::detail;

int main() 
{  
    //contents
    std::stringstream s(
            "a = 1\n"
            "b = 2\n"
            "c = test option\n");
    //parameters
    std::set<std::string> options;
    options.insert("a");
    options.insert("b");
    options.insert("c");

    //parser
    for (pod::config_file_iterator i(s, options), e ; i != e; ++i)
    {
        std::cout << i->value[0] << std::endl;
    }
}

我认为情况会顺利,但实际上有一些错误:

/tmp/ccNQEbJM.o: In function `boost::program_options::detail::basic_config_file_iterator<char>::basic_config_file_iterator(std::basic_istream<char, std::char_traits<char> >&, std::set<std::basic_string<char, std::char_traits<char>, std::allocator<char> >, …
