Same error on my Ubuntu 16.04. Does anyone has solution for it?

Add #define OPENCV_TRAITS_ENABLE_DEPRECATED in fastfusion/src/auxiliary/plywriter.h before #include<opencv2/opencv.hpp> should work.

If similar error happens afterwards in another file, do the same thing in the corresponding header file.
