How resolve problem of use of deleted function std basic_stringstream

[ysf007]

I've written the following in windows on Qt IDE and when I run it, it works well,
however where I tried to run on centOS with

g++ -std=gnu++11 main.cpp -o main

I get these errors

  #include <string>   // for strings
  #include <iomanip>  // for controlling float print precision
  #include <sstream>  // string to number conversion

  #include <future>
  #include <fstream>
  #include <string>

Streams are not copyable. C++11 made them moveable and this is what makes it possible to return a local stringstream object from a function. Unfortunately GCC 4.8 had not yet added the move constructor that was necessary for this to work.

Consider solving your problem some other way, perhaps by making the function return the result as a string, or upgrade to a later version of GCC.
