Dear all,
I found out that the program
#include <iostream>
#include <ginac/ginac.h>
using namespace std;
using namespace GiNaC;
int main(int argc, char** argv)
{ symbol x("x");
ex_to<power>(x*x).dbgprint();
return 0;
}
gives the output
[power object]
This is because in basic::dbgprint a print_context is constructed from
std::cerr and not a print_dflt. Changing, in basic::dbgprint, the line
this->print(std::cerr);
into
this->print(print_dflt(std::cerr));
solves this problem.
Now the output is
x^2
as expected.
Best,
Chris
