boost多索引插入编译错误

Question

我正在尝试在共享内存中创建一个多索引容器，例如 http://www.boost.org/doc/libs/1_55_0/doc/html/interprocess/allocators_containers.html#interprocess.allocators_containers.containers_explained

在我的示例中，我有几个键 IMSI、IMEI、... 我在以下行出现错误

m_pGlobalHash->insert(key);

这里是代码

#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);
    }
};

我得到的错误很长，所以这里只是其中的一部分：

如果答案是获取特定索引，然后插入。我应该得到哪个索引，为什么？

Answer 1

这是 Boost.MultiIndex 的 Boost 1.55 版本中的一个错误，已在即将发布的 Boost 1.56 中修复。您可以在
