Hi, basically, you need to add "#include ", and correct some other bugs... #include <iostream> #include <valarray> #include #include class A { std::valarray<int> member_one; std::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() { A p; { boost::archive::text_oarchive oarchive(std::cout); oarchive << p; } return 0; } Regards, Mirko On Sun, Dec 22, 2019 at 3:13 AM Meik via Boost-users < boost-users@lists.boost.org> wrote:

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

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.
