[tuple, lambda] predicate does not compile
Hello Newsgroup, in the following code the call bind (&boost::tuple<int, double>::get<0>, _1) does not compile whereas an analogous call with a non-template parameter compiles fine. What am I doing wrong? I'm using boost 1.33.1 and Visual Studio 7.1 Thanks in advance, Christian #include <vector> #include <algorithm> #include <string> #include <boost/lambda/lambda.hpp> #include <boost/lambda/bind.hpp>

If I remember correctly, get has two overloads (one const, one without const). One cannot take the address of an overloaded (member) function without specifying its type. (This is without looking at the tuple code, so comes with a caveat) Best, Jaakko Järvi

Best, Jaakko Järvi
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: error C2440: 'static_cast' : cannot convert from 'overloaded-function' to 'int (__thiscall boost::tuples::tuple<T0,T1>::* )(void)' with [ T0=int, T1=double ] None of the functions with this name in scope match the target type The entire error message is attached. Thanks, Christian

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
