Здравствуйте, Stanislav V. Zudin, Вы писали:

# ifdef BOOST_ERROR_CODE_HEADER_ONLY
#   define BOOST_SYSTEM_LINKAGE inline
# else
#   define BOOST_SYSTEM_LINKAGE BOOST_SYSTEM_DECL
# endif

    BOOST_SYSTEM_LINKAGE const error_category & system_category() BOOST_SYSTEM_NOEXCEPT
    {
      static const system_error_category  system_category_const;
      return system_category_const;
    }

Проще собрать с BOOST_ERROR_CODE_HEADER_ONLY.
