Hello,
I'm experiencing troubles with functional/hash
#include #include
typedef boost::mp_math::integer<> big_integer;
class A {
friend A operator*( const big_integer& lhs, const A& rhs ) {}
};
gives the following madness. What surprises me is that I am not making
any use of functional/hash (in the actual code, it gets included from
boost/unordered_map.hpp), as the error messages don't indicate any line
of my code. I think mp_math is not playing a big role here, once I had
the same problem with a homemade class (but unfortunately I can't now
replicate the same conditions).
Can anyone explain me what is going on here ?
Thanks you all in advice, Andrea
