提高多指數插入編譯錯誤

Question

我試圖做多指數容器共享內存就像http://www.boost.org/doc/libs/1_55_0/doc/html/interprocess/allocators_containers.html#interprocess.allocators_containers.containers_explained

在我的例子，我有幾個鍵IMSI，IMEI，... 我得到一個錯誤在下一行

m_pGlobalHash->insert(key); 

下面是代碼

#include <boost/interprocess/managed_shared_memory.hpp> 
#include <boost/multi_index_container.hpp> 
#include <boost/multi_index/hashed_index.hpp> 
#include <boost/multi_index/member.hpp> 
#include <boost/multi_index/indexed_by.hpp> 

namespace bmi = boost::multi_index; 
namespace bip = boost::interprocess; 

typedef uint32_t RU32; 
typedef uint64_t RU64; 

struct SrValue{ 
    RU32 nVal1; 
}; 

struct UsersKey{ 
    RU64 IMSI; 
    RU64 IMEI; 
    SrValue value; 
}; 


struct IMSI_tag{}; 
struct IMEI_tag{}; 

typedef bmi::hashed_unique<bmi::tag<IMSI_tag>, 
    bmi::member<UsersKey, RU64 , &UsersKey::IMSI>,boost::hash<RU64>, std::equal_to<RU64> 
    > hashed_by_IMSI; 
typedef bmi::hashed_unique<bmi::tag<IMEI_tag>, 
    bmi::member<UsersKey, RU64 , &UsersKey::IMEI>,boost::hash<RU64>, std::equal_to<RU64> 
    > hashed_by_IMEI; 

//index struc definition 
struct UsersKey_hash_indices: 
    bmi::indexed_by< 
    hashed_by_IMSI, 
     hashed_by_IMEI>{}; 


class CrMultiParameterMultiIndex 
{ 
    typedef boost::multi_index::multi_index_container< 
     UsersKey, 
     UsersKey_hash_indices, 
     bip::allocator<UsersKey,bip::managed_shared_memory::segment_manager> 
    > GlobalHash; 

    boost::interprocess::offset_ptr<GlobalHash> m_pGlobalHash; 
public: 

    void Insert(const UsersKey & key) 
    { 
     m_pGlobalHash->insert(key); 
    } 
}; 

我得到的錯誤是非常非常長，所以這裏只是它的一部分：

如果答案是獲得一個特定的指數，然後再插入。我應該得到哪個索引，爲什麼？

Answer 1

這是Boost.MultiIndex的Boost 1.55版本中的一個錯誤，在即將到來的Boost 1.56中已經修復。你可以看到這個問題有更全面的說明（補丁一起，你可以下載，直到升壓1.56不在本地應用）在
