Could I have the complete error message with line numbers, also what compiler are you using.

I am using GCC version gcc (Ubuntu 5.4.1-2ubuntu1~16.04) 5.4.1 20160904

. What changes to the make file needs to be done?

Gcc 5.4.1 may not support enough of C++11 you might need to upgrade to a newer version. See the README.
