Thread Module in c++11

C++11 supports Thread library (http://en.cppreference.com/w/cpp/thread). If you are using it in your application you have to pass -pthread to g++ linker to inform it which sort of backend should be used for linking Thread library. If -pthread is not passed your application will end up with following execution error:

terminate called after throwing an instance of 'std::system_error'
 what(): Enable multithreading to use std::thread: Operation not permitted
Aborted (core dumped)
