[GiNaC-devel] is_ex_the_function

1 Feb 2013

      Hi,

I can't understand why, when I try to use is_ex_the_function with the power 
function, I get a:
...
...
error: ‘power_SERIAL’ was not declared in this scope
My code is something like this:

  symbol x("x");
  ex expr = power(x, 2);
  std::cout << expr << std::endl;
  std::cout << is_ex_the_function(expr, power) << std::endl;

I get my error on line 4.

On the other hand, everything works fine with:

  symbol x("x");
  ex expr = sin(x);
  std::cout << expr << std::endl;
  std::cout << is_ex_the_function(expr, sin) << std::endl;

Could you please help me?

Thank you,

Luca-
