boost :: serialization :: shared_ptr_helper出错 [英] Error with boost::serialization::shared_ptr_helper

问题描述

通过，我得到了错误:

/usr/local/include/boost/serialization/shared_ptr_helper.hpp:182:20: error: no matching function for
call to 'std::map<const void*, std::shared_ptr<void>, std::less<const void*>, std::allocator<std::
pair<const void* const, std::shared_ptr<void> > > >::insert(std::pair<const void*, std::
shared_ptr<const bagel::Atom> >)'
             result = m_o_sp->insert(std::make_pair(oid, s));

怎么了? std和boost的版本都是最新的.

What's wrong?? The version of std and boost are both the newest.

推荐答案

您当然不会通过包含"获得该内容.我知道这一点，因为bagel::Atom不是提升的一部分.

You certainly do not get that "by including". I know this, because bagel::Atom is not a part of boost.

您根本无法期望在没有显式强制转换(static_pointer_cast?)的情况下将shared_ptr<const bagel::Atom> >存储到std::shared_ptr<void>中.

You simply cannot expect to store a shared_ptr<const bagel::Atom> > into a std::shared_ptr<void> without an explicit cast (static_pointer_cast?).

使用

std::map<void*, std::shared_ptr<void> >

是一种巨大的设计气味.您绝对不能期望其中任何一个会自动序列化(因为void如何被有效地序列化?)

is a huge design smell though. You can definitely not expect any of that to be automatically serialized anyway (because, how would void be usefully serialized?)
