bind(&map::insert,
insert is overloaded and the compiler doesn't know which one you mean.
You'll need to cast it to the right type.

Based on your answer and the Boost lambda docs
(http://www.boost.org/doc/libs/1_42_0/doc/html/lambda/le_in_details.html#lamb...) 
I changed the code to:
...
template< typename Predicate >
map getObjectsFromMap( const Predicate& aPredicate)
{
  pair< map< string, string >::iterator, bool > (*InsertFn)(const map::value_type&) = &map::insert;
Try pair<...> (map::* InsertFn)(const 
map<...>::value_type&) = ...;
...
map matchedObjects;
  for_each(	objectsMap.begin(),
           	objectsMap.end(),
           	if_then(
           		bind(aPredicate, _1) ,
           		bind(InsertFn,
           		     &matchedObjects ,
           		     make_pair(bind(&map::value_type::first, _1),bind(&map::value_type::second,_1)))));
  return matchedObjects;
}
But that gives me more errors than I could imagine. Could you give me a
bit more info as I am really lost here.
