[Boost-users] [bind] bind and static tables

Hi there, for whatever reason the following code doesn't compile:

#include <string>
#include <algorithm>
#include <functional>
#include <vector>

#include <boost/any.hpp>
#include <boost/bind.hpp>

using namespace std;
using namespace boost;

struct A {};
struct B {};

struct field
{
   const any a;
   const string s;
};

static field table[] =
{
   { any( A() ), "Hello" },
   { any( B() ), "Moin" }
};

template<class T>
const T& get( field* p )
{
   return p->s;
}

int _tmain(int argc, _TCHAR* argv[])
{
   string s( "Hello" );

   size_t size = sizeof(table) / sizeof(field);

   field* p = find_if( &table[0], &table[0] + size, boost::bind(
equal_to<string>()
                                                   , bind( get<string>, _1 )
                                                   , s   ));
}

The problem is that bind doesn't like it when _1 is a pointer. I
believe. So, what is wrong? On some other threads I could see that
slightly different example worked.

Thanks ahead,
Christian
