Setting g++ options in root


I am trying to run a c++ script in root where I use “std::to_string(Value)” to convert numerical value to a string.

To my knowledge, this function works if we have C++11 support and to enable it we have to use “g++ -std=c++11”.

My question is, how do I enable this “-std=c++11” option of g++ in root. Or in general, how do we enable any of the gcc/g++ command options in root?

I am working on Ubuntu 14.04, ROOT v5.34 and I have g++ v4.8.2.

Best Regards
