boost::binary_wiarchive gives linking error

Question

I'm using:

Visual studio 2013 Update 5;
Boost 1.57.0; built using boost site documentation except that for address-model=64 flag (I need to create 64bit applications).

I've created a new project for testing serialization. This code compile just fine:

#include <boost/archive/binary_iarchive.hpp>
#include <boost/serialization/nvp.hpp>
#include <fstream>

struct MyStruct {
  double data;

private:

  friend class boost::serialization::access;

private:

  template<class Archive>
  void serialize(Archive & archive, const unsigned int version) {
    archive & BOOST_SERIALIZATION_NVP(data);
  };
};

int main() {
  std::ifstream fileStream("myfile.xml");
  boost::archive::binary_iarchive archive(fileStream);
  MyStruct myStruct;
  archive >> BOOST_SERIALIZATION_NVP(myStruct);
  return 0;
}

But if I pass to wide char I obtain linking errors.

This code:

#include <boost/archive/binary_wiarchive.hpp>
#include <boost/serialization/nvp.hpp>
#include <fstream>

struct MyStruct {
  double data;

private:

  friend class boost::serialization::access;

private:

  template<class Archive>
  void serialize(Archive & archive, const unsigned int version) {
    archive & BOOST_SERIALIZATION_NVP(data);
  };
};

int main() {
  std::wifstream fileStream(L"myfile.xml");
  boost::archive::binary_wiarchive archive(fileStream);
  MyStruct myStruct;
  archive >> BOOST_SERIALIZATION_NVP(myStruct);
  return 0;
}

Gives me these linking errors:

I've seen in another reply that I can use binary_iarchive in order to save also wide char strings, but I'd like to use wifstream in order to maintain uniformity across the code for other reasons.

Is there a way to use binary_wiarchive correctly?

There are two serialization libraries -- `boost_serialization` and `boost_wserialization`. In the second example, you're probably still linking with the former, rather than the latter. — Dan Mašek, May 13 '16 at 08:18
I'm not linking anything. I'm using the auto linking option of boost. It should be able to select the right library, correct? — Jepessen, May 13 '16 at 08:37
I can't vouch for that, I have auto linking disabled in my project. However, looking at the [source](https://github.com/boostorg/serialization/blob/boost-1.57.0/include/boost/serialization/config.hpp#L71) it seems to me the automatic linking is only implemented for the non-wide variant. -- Never mind, [found it](https://github.com/boostorg/serialization/blob/boost-1.57.0/include/boost/archive/detail/auto_link_warchive.hpp#L34). Odd, dunno. — Dan Mašek, May 13 '16 at 08:41
