[Boost-users] Cannot compile with multiprecision :: eval_*() functions

Hi folks,

I am trying to use eval_pow() and eval_powm()

My code is like this and I am using Visual Studio 12:

#include <boost/multiprecision/cpp_int.hpp>
...
boost::multiprecision::cpp_int pow("1234567");
boost::multiprecision::cpp_int base(3);
boost::multiprecision::cpp_int result = 0;

boost::multiprecision::default_ops::eval_pow(result, base, pow);

I cannot figure out what's going on wrong when I compile it, the error
message is like the following, Can anyone shed some light please?
