変換 'のstd :: __ cxx11 :: <char>をのbasic_string' 'のstd :: ostream_iterator <char>'

Question

にI次の簡単なコードを持っている：私は使用してgccでコンパイルしよう

#include <boost/program_options.hpp> 
#include <iostream> 
#include <iterator> 
#include <string> 
#include <vector> 
#include <algorithm> 

using namespace std; 
namespace po = boost::program_options; 

int main(int argc, char *argv[]) 
{ 

    po::options_description config("Configuration"); 
    config.add_options() 
     ("optimization", po::value<int>()->default_value(10), 
       "optimization level") 
     ("include-path,I", 
      po::value< vector<string> >()->composing(), 
      "include path") 
     ; 


    po::variables_map vm; 
    po::store(po::parse_command_line(argc, argv, config), vm); 

    auto popts = po::parse_config_file<char>("config.ini",config,true); 
    po::store(popts,vm); 
    po::notify(vm); 

    for(auto o:popts.options) { 
      cout << o.string_key << "=" << "\n"; 
      std::copy(o.value.begin(), o.value.end(), std::ostream_iterator<char>(std::cout, " ")); 
    } 

    return 0; 
} 

：

g++ -std=c++11 test.cpp 

これは私に次のエラー与える：

は、私が何をしないのですか？これはABIの非互換性ですか？

私はgcc 6.2.1を使用し、1.61をブーストしています。

（注：はい、私は、同様のブーストライブラリをリンクする必要がありますが、ここでの問題は、コンパイラのエラーである）

Answer 1

はエラーを自分自身を発見しました。

代わりの

std::copy(o.value.begin(), o.value.end(), std::ostream_iterator<char>(std::cout, " ")); 

それは

std::copy(o.value.begin(), o.value.end(), std::ostream_iterator<string>(std::cout, " ")); 

（代わりにstringの間違ったテンプレートパラメータchar）されている必要があります。
