Sorry. I didn't sere the comments the first time.

This code is basically defining a class that has the same name as a function
(record_predecessors) that is already defined in the BGL. Change the name of
the class (and constructor) and it should work fine. It did for me.

Or you could just use the predecessor_recorder class, which is created by
the record_predecessor function :)
