Seems like the compiler wants to use the boost:: placeholders instead of the std:: ones despite you using std::bind. You could change _1, ... with std::placeholders::_1, ... or, maybe a little less verbose, use a local using declaration for the correct namespace i.e. using namespace std::placeholders; to import the names for resolution.

Maybe a lambda instead of std::bind altogether if you're using at least C++11, but here I might be wrong.
