tree.hh doesn't compile on Ubuntu 14.04

Question

I am using the latest tree.hh from http://tree.phi-sci.com/download.html. It produces the errors (please see below). How can I fix it? How can this class produce so many errors? Thanks in advance for your suggesstions?

How did you compile it? Did you compile it with c++11 support? — Xiaotian Pei, Nov 08 '15 at 19:25
It's good that you showed the code and the error message. You should also show the command-line used for compilation. — Brent Bradburn, Nov 08 '15 at 19:28

&& is C++ 11 feature. You should use --std=c++11 or --std=gnu++11 command line option when making g++ call.
