Thanks for the hint. If I add a "const std::string getA () const {return a_;}" to the SearchForMe class then I have to change

bind (&SearchForMe::getA, _1) == "apple");

to

bind (static_cast<string (SearchForMe::*)()> (&SearchForMe::getA), _1) == "apple");

or to

bind (static_cast<string (SearchForMe::*const)()> (&SearchForMe::getA), _1) == "apple");

and everthings works fine. However, if I do the same with the tuple-code

bind (static_cast<int (boost::tuple<int, double>::*)()> (&boost::tuple<int, double>::get<0>), _1) == 15);

I still get compile errors:

Get returns a reference. So try: bind (static_cast<int& (boost::tuple<int, double>::*)()> ... instead. Best, Jaakko
