compiler and stoi()

[pavik]

I'm using CodeBlocks, with GNU GCC compiler (ver. (tdm-1) 4.9.2). In Global Compiler settings the "Have a g++ follow the C++ ISO C++ language standard [-std=c++11]" flag is ticked.

I'd like using function stoi() (header <string> is included). Compiling is unsuccessful with error message "error 'stoi'was not declared in this scope"

How could I get rid of this issue?
