Why it doesn't work?

--- boost_bind.cc ---

#include 
#include 
#include 

void func1 (const int& i)
{ }

void func2 (const ::asio::error_code& e)
{ }

int main ()
{
    ::boost::function f1 = ::boost::bind (&func1, 1);

    // it doesn't work!
    ::boost::function f2 = ::boost::bind (&func2, ::asio::placeholders::error);

    return 0;
}

This is the error:
