Hi,
Boost.Serialization has support for non-default classes using save_construct_data and load_construct_data overloads. These are called before serialization to save and load information that's important for the construction of the object. Unfortunately, multi_index doesn't call these functions when serializing, so serialization of non-default-constructible classes is impossible with multi_index.
Hi, seems you spotted a bug here. load_construct_data_adl is actually used (see boost/multi_index/detail/archive_constructed.hpp ), but this is not the case for save_construct_data_adl, which is also necessary. I'll fix this. I'd appreciate if you can file a ticket in the Trac system. Meanwhile you can try your hand patching boost/multi_index_container.hpp: lines 646-647 (in 1.41, some offset might occur in 1.38) look like for(iterator it=super::begin(),it_end=super::end();it!=it_end;++it){ ar<<serialization::make_nvp("item",*it); save_construct_data_adl should be called before "ar<<..." with *it. Please report back about your success or lack of it. Thank you for using Boost.MultiIndex. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo
