錯誤地圖shared_memory提高

Question

我試圖創建一個進程間共享內存，我有一個編譯錯誤

這裏駐留的問題是代碼：

typedef bip::basic_string< char,std::char_traits<char>, 
bip::allocator<char,bip::managed_mapped_file::segment_manager> > shared_string; 

typedef  shared_string MappedType; 
typedef  shared_string MappedType; 
typedef  const int KeyType; 

typedef std::pair<const int, shared_string> ValueType; 

//Alias a map of ints that uses the previous STL-like allocator. 
//Note that the third parameter argument is the ordering function 
//of the map, just like with std::map, used to compare the keys. 
typedef bip::map<KeyType, MappedType, std::less<KeyType>, ShmemAllocator> MyMap; 

mymap = 
      seg->find_or_construct<MyMap>("MyMap")  //object name 
      (std::less<int>() //first constructor parameter 
      ,*alloc_inst); 

，我有問題，創建地圖。錯誤是：

c:\GQSDevEnv\3rdParty\boost\boost_1_36_0\boost\interprocess\containers\map.hpp(437) : error C2535: 'std::pair<_Ty1,_Ty2> boost::interprocess::map<Key,T,Pred,Alloc>::insert(const boost::interprocess::map<Key,T,Pred,Alloc>::value_type &)' : member function already defined or declared 
     with 
     [ 
      _Ty1=boost::interprocess::detail::rbtree<const Testing::KeyType,std::pair<const int,Testing::shared_string>,boost::interprocess::detail::select1st<std::pair<const int,Testing::shared_string>>,std::less<const Testing::KeyType>,Testing::ShmemAllocator>::iterator, 
      _Ty2=bool, 
      Key=const Testing::KeyType, 
      T=Testing::MappedType, 
      Pred=std::less<const Testing::KeyType>, 
      Alloc=Testing::ShmemAllocator 
     ] 

我必須聲明不同嗎？我工作的時候，當我在std :: pair中輸入一個Template的類型名稱，但是現在我想嘗試只輸入一個int ...我不知道爲什麼會出現這個錯誤...

感謝致歉

由於您使用的是爲什麼你不使用boost shared_memory_object？
