Sadly, the same problem: works with msvc 7.1 put not intel 9.0:
error: more than one instance of overloaded function "mem_fn" matches the argument list: function template "boost::mem_fn(R (T::*)() const)" function template "boost::mem_fn(R (T::*)())" argument types are: (<unknown-type>)
This problem initially came up when I was using boost::bind in this way:
make_transform_iterator(v.begin(), bind(&array_type::at, _1, 0))
This is a bug in MSVC 7.1, I guess. You need to disambiguate:
array_type::reference (array_type::* pmf) (array_type::size_type) = &array_type::at;
make_transform_iterator( v.begin(), bind(pmf, _1, 0) );
Unfortunately, there is no way to tell from bind(&array_type::at, _1, 0) whether you need the const or non-const overload, and it is not possible to somehow store both overloads for later use.
Peter, thanks, you rock. I finally understand what is going on here.
Is this a more elegant way?
boost::make_transform_iterator(v.end(),
bind(static_cast
