Hello,

Could someone please explain the following behavior:

#include #include

struct Functor {        void operator()() const        {}        template<class T> void func(T t)        {} };

int main() {        Functor f;        boost::lambda::bind(&Functor::func<Functor>, &f, f); // doesn't compile        boost::bind(&Functor::func<Functor>, &f, f); // compiles well }

Does it work with Boost.Phoenix? Boost.Phoenix includes the functionality of both and a great deal more. I have not tried this, but curious if it works for you: #include #include #include struct Functor { void operator()() const {} template<class T> void func(T t) {} }; int main() { Functor f; boost::phoenix::bind(&Functor::func<Functor>, &f, f); // Does this compile? boost::lambda::bind(&Functor::func<Functor>, &f, f); // doesn't compile boost::bind(&Functor::func<Functor>, &f, f); // compiles well }

Another strange behavior: struct Functor { void func1() const {} }; int main() { boost::shared_ptr<Functor> pf1; Functor *pf2; boost::function f1 = boost::bind(&Functor::func1, pf1); // boost.bind with shared_ptr and store in function - OK boost::lambda::bind(&Functor::func1, pf1); // labmda bind with shared_ptr - OK boost::function f2 = boost::lambda::bind(&Functor::func1, pf2); // lambda bind with regular ptr and store in function - OK boost::function f3 = boost::lambda::bind(&Functor::func1, pf1); // lambda bind with shared_ptr and store in function - FAILS } Phoenix behaves the same way.
