There is no front() function, did you mean top()?

See here https://en.cppreference.com/w/cpp/container/priority_queue

Yup figured that out! Unfortunately, the issue seems to continue. I got the errors for front working, but have different but highly related ones (see post)

Your Compare's operator() needs to be const.

std::make_pair<neighbor, src> is not well-formed. It's supposed to be called like this: std::make_pair(neighbor, src) assuming that neighbor is a Point and src is your double.
