Hello,

I am new to C++ and thus new to Boost. My goal is to serialize a class containing multiple std::valarrays with primitives as content.

The code I wrote to achieve that(minimal example to reproduce):

    #include <iostream>
    #include <boost/archive/text_oarchive.hpp>

    class A {
        valarray<int> member_one;
        valarray<float> member_two;
        friend class boost::serialization::access;
       
        template<class Archive>
        void serialize(Archive &ar, const unsigned int version){
                ar & member_one;
                ar & member_two
        }
    }
    int main(int argc, char* argv[]) {
        boost::archive::text_oarchive oarchive(cout);
        oarchive << p;
        return 0;
    }

When compiling this, the following error is given:

error: class std::valarray<int> has no member names serialize

I'd appreciate if you could let me know how to correctly serialize said std::valarray.

Kind regards,
Meik S.
