Re: [Boost-users] function object wrapper problem

Thanks,

But also without any other constructor (for both some_class and
some_other_class) I get the compiler error.

I did another test.
I created a function with exactly the same signature as the some_class constructor;

template <class T>
some_func(const boost::function1<T*, short*>& some_member)
{
}

and now the compiler says;

error C2784: 'int some_func(const boost::function1<T*,short*> &)' : could not
deduce template argument for 'const boost::function1<R*,short*> &' from
'boost::_bi::bind_t<R,F,L>'
        with
        [
            R=short *,
            F=boost::_mfi::mf1<short *,some_other_class,short *>,
            L=boost::_bi::list2<boost::_bi::list_av_2<some_other_class *__w64
,boost::arg<1>>::B1,boost::_bi::list_av_2<some_other_class *__w64
,boost::arg<1>>::B2>
        ]
        c:\Temp\com\com.cpp(14) : see declaration of 'some_func'

Somehow the compiler does not instantiate the function properly when a templated
argument is only fed into the function wrapper.

Any ideas?
