[Boost-users] optional + serialize

Hi Jeff, All! thanks a lot for the reply. I assume the bug fix is in 1.33? I'm still having issues with boost.optinal and boost.serialize working together (in 1.32). Is for deserialization of boost::optional<T> T required to have default ctor?. This prevents boost::optionalboost::posix_time::time_period from being serialized. The extraction code fails to compile. I would an ugly way around this (please see my last email). Does anybody have ideas for better solutions? I've attached a modified version of #include to this email, that contains code changes to make to work with types w/o T having a default ctor. But I'm really unhappy with that solution and I don't know what I broke with this change... thanks in advance Alex

... Another thing is that I'm unable to serialize not_a_date_time ptimes. The extractions fails here. I'm using the binary archive. Is that supported? The documentation of date time only states compatibility with text and XML archive...

There was a recent (jun 21) bug-fix in date-time that was preventing correct serialization of special values -- even with text archives -- so it's likely that's what you are seeing. I haven't tried the binary archive, but there's no reason it shouldn't work. I believe you should be able to just pickup the latest version of gregorian/greg_serialize.hpp and posix_time/time_serialize.hpp to try it out.
