[Boost-users] [Boost][Bind] How to bind template function member

Hi,

I would like to know how I can use boost::bind with template function
member? 

To explain my problem, you will find hereafter an example code that
demonstrates it. In this code, when we try to bind the function member
X::g the compiler failed with tons of error message. 

Am I doing something wrong?

Best regards,

#include <boost/bind.hpp>

struct X {
  template<typename A, typename B> 
    void g(A& a, B& b)
  { std::cout << a << " " << b << '\n' ; }

  void
    f(int& i) 
  { std::cout << i << '\n'; }
} ;

template<typename A, typename B> 
  void e(A& a, B& b)
{ std::cout << a << " " << b << '\n' ; }

int
main(int argc, char* argv[])
{
  int a = 10, b = 11 ;
  X x ;
  boost::function<void (void)> pe = boost::bind(&e<int,int>, a, b) ;
// <- OK
  pe() ;
  boost::function<void (void)> pg = boost::bind(&X::g<int,int>, &x, a,
b) ; // <- Don't compile?
  pg() ;
  boost::function<void (void)> pf = boost::bind(&X::f, &x, a) ;
// <- OK
  pf() ;
 }
