Q: deserialize after updating dealii

[Najwa Alshehri]

Dear developers and group members,

I was using an old version of Dealii where I was serializing some solutions and deserializing them where needed. In the code where I deserialize the solution I used to use the following headers:

#include <boost/archive/text_iarchive.hpp>

#include <boost/archive/text_oarchive.hpp>

#include <boost/serialization/vector.hpp>

#include <fstream>

#include <iostream>

and I used 

std::ifstream iss("serialized_ex2");

boost::archive::text_iarchive ia(iss);

It used to work fine. However, after updating Dealii, the code breaks and I get the following error:

Exception on processing:
unregistered class
Aborting!

Do you have an idea of what could be the missing header or class?

Your help is highly appreciated,

Najwa

Najwa,

Are you serializing/deserializing the solution using the same version of deal.II and Boost? If you serialized the solution using the old version of deal.II, I don't think you can deserialize it using a newer version of deal.II

Hello Bruno,

I have the solution serialized with the old version. Do you think this is the issue? I will do everything with the new version today and update you if it works.

Best,

Dear Bruno,

I appreciate your observation. I reprocessed the solution by serializing it with the updated version of Dealii, and subsequently, when I deserialized it in a different code, it functioned as expected. 

I appreciate your help.

Best,

Najwa
