AUR built error

Question

While installing/building cadabra2-git from AUR (Antergos, with kernel 4.11.3-1-ARCH) I get the following makefile error

Any help will be greatly appreciated.

Answer 1

It looks like core/Functional.hh should have had a line

#include <functional>

at the top (below the #pragma once line). Can you add that and let me know?

My compiler is apparently not picky enough to bail out on this one.
