I'm a newbie to Phoenix, just exploring, but I guess my intent in this code is

obvious. Can anyone tell me what I'm doing wrong?

Thx

#include <iostream>

#include <boost/spirit/include/phoenix_core.hpp>

#include <boost/spirit/home/phoenix/operator.hpp>

#include <boost/spirit/home/phoenix/statement.hpp>

#include <boost/function.hpp>

using namespace boost::phoenix;

using namespace boost::phoenix::arg_names;

using namespace std;

int main()

{

boost::function<unsigned( unsigned )> factorial;

factorial = if_else( _1 == 0, 1, _1 * factorial( _1 - 1 ) );

cout << factorial( 3 ) << endl;

return 0;

}
