Boost serialization: archive "unsupported version" exception

I've got the exception "unsupported version" when I try to deserialize through a text archive some data previously serialized with a upper version of Boost (1.46 to serialize and 1.38 to deserialize)...is there a way to downgrade (in the code) the serialization?

Something like "set_lib开发者_如何学Gorary_version"?


See the Error read binary archive, created by old Boost version mail archive post about the serialization error.

It says that the code below does the job:

void load_override(version_type & t, int version){

    library_version_type lvt = this->get_library_version();
    if (boost::archive::library_version_type(7) < lvt){
        this->detail_common_iarchive::load_override(t, version);
    }
    else
        if (boost::archive::library_version_type(6) < lvt){
            uint_least16_t x = 0;
            * this->This() >> x;
            t = boost::archive::version_type(x);
        }
        else
            if (boost::archive::library_version_type(3) == lvt ||
                boost::archive::library_version_type(5) == lvt){

                #pragma message("CTMS fix for serialization bug (lack of backwards compatibility) introduced by Boost 1.45.")
                // Up to 255 versions
                unsigned char x = 0;
                * this->This() >> x;
                t = version_type(x);
            }
            else{
                unsigned int x = 0;
                * this->This() >> x;
                t = boost::archive::version_type(x);
            }
}


Using text_archive ... I had a recent issue with this also. I recently upgraded boost from 1.67 to 1.72 on Windows, generated some data on Windows. When I ran the data on my Linux environment which is still on Boost 1.67, it throws not supported.

The header for 1.67 looked like this

22 serialization::archive 16

and 1.72 looked like

22 serialization::archive 17

I changed 17 to 16 and it was happy for my use case.
