When compiling with -std=c++17 this should compile without change. For earlier
versions of the standard, you will have to define a serialization function for
your type explicitly:
template <typename Archive>
void serialize(Archive& ar, point& pt, unsigned)
{
ar & pt.ig & pt.set;
}
That should do the trick.
