的boost :: multi_index错误“模板参数‘X’是无效的”

Question

所以我做了某种数据库，像这样boost_multi_index：

#include <boost\multi_index_container.hpp> 
#include <boost\multi_index\ordered_index.hpp> 
#include <boost\multi_index\member.hpp> 
using namespace boost::multi_index; 
using namespace std; 

struct list_entry{ 
    int id; 
    string name; 
    string* data; 
}; 

typedef multi_index_container<list_entry, 
    indexed_by< 
     ordered_unique< tag<int>, member<list_entry, int, &list_entry::id>>,    // unique id 
     ordered_unique< tag<string>, member<list_entry, string, &list_entry::name>>,  // unique name 
     ordered_non_unique< tag<string*>, member<list_entry, string*, &list_entry::data>> // some data associated with the id/name 
    > 
>table; 

class Database 
{ 
    private:  
     table music, names; 
     typedef table::index<int>::type list_id; 
     typedef table::index<string>::type list_string; 

    //some more code here 
}; 

，并与Visual Studio编译罚款2010

然而我想在与MinGW的代码:: Blocks的转换我的项目，好像他不是那么满意了，这是编译日志：

我完全一无所知，因为错误是没有任何更多SPE比这个更重要，我也找不到任何相关的问题。

所以我希望有人可以在这里给我一个答案，如果需要更多信息，我会在之后进行编辑。

Answer 1

我能够通过使用BOOST_MULTI_INDEX_MEMBER这样来解决这个问题：

typedef multi_index_container<list_entry, 
    indexed_by< 
     ordered_unique< tag<int>, BOOST_MULTI_INDEX_MEMBER(list_entry, int, id)>, 
     ordered_unique< tag<string>, BOOST_MULTI_INDEX_MEMBER(list_entry, string, name)>, 
     ordered_non_unique< tag<string*>, BOOST_MULTI_INDEX_MEMBER(list_entry, string*, data)> 
    > 
>table;
