Hi, I'm new to C++, working on an old project using the vs2008 toolset. I need to add some networking and so I started with the docs tutorial "An asynchronous TCP daytime server".
Boost 1.68

Error    C2027    use of undefined type 'boost::_bi::add_cref<Pm,I>'    BoostAsio    d:\downloads\boost_1_68_0\boost\bind\bind.hpp    2323        


namespace _bi
{template< class Pm, int I > struct add_cref;
...

template<class Pm, class A1> struct dm_result
{
    typedef typename add_cref< Pm, 1 >::type type;    <<< 2323
};
Do I need to provide more details?
Thanks
