[GiNaC-list] Namespace error with is_ex_the_function

18 Oct 2015

      Hello,

The following program

#include <iostream>
#include <ginac/ginac.h>

int main() {
   GiNaC::symbol x("x");
   std::cout << GiNaC::is_ex_the_function(x, GiNaC::sin) << std::endl;
}

gives me a compilation error:

bug.cpp:6:24: error: unexpected parenthesis after '::'
   std::cout << GiNaC::is_ex_the_function(x, GiNaC::sin) << std::endl;
                       ^

This is with GiNaC 1.6.5 on Mac OS 10.11, with compiler Apple version 7.0.0. It seems there is an issue with the namespace. Removing `GiNaC::` from `is_ex_the_function` compiles fine. Anyone else have this?

Cheers,
