恆圖初始化在C++

Question

可能重複：
Initializing a static std::map<int, int> in C++

我本善良地圖：

{'V', 'O'} 
{'v', 'о'} 
{'H', 'В'} 
{'h', 'в'} 
{'W', 'Ш'} 
{'w', 'ш'} 

但在VS 2005中，當我運行

const static std::map<char, wchar_t> mapDimLetters = 
{ 
    {'V', 'O'}, 
    {'v', 'о'}, 
    {'H', 'В'}, 
    {'h', 'в'}, 
    {'W', 'Ш'}, 
    {'w', 'ш'}, 
} 

測試

error C2552: 'mapDimLetters' : non-aggregates cannot be initialized with initializer list 
1>  'std::map<_Kty,_Ty>' : Types with a base are not aggregate 
1>  with 
1>  [ 
1>   _Kty=char, 
1>   _Ty=wchar_t 
1>  ] 
error C2078: too many initializers 

我怎樣才能解決這個問題？或者以最有效的方式定義具有常量已知值的映射的最佳方法是什麼？

爲什麼不使用boost assign？

#include <map> 
#include "boost/assign.hpp" 
using namespace boost::assign; 


const std::map<char, wchar_t> mapDimLetters = map_list_of 
     ('V','O') 
     ('v','o') 
     ('H','B') 
     ('h','b');
