'to_string' is not a member of 'std'

Question

i compile the project with the mingw and the project is cool compiler . this is a part of my code

#include "astnodecodegenerator.hpp"
#include "utility.hpp"
#include "constants.hpp"
#include <string>
#include <cmath>
#include <sstream>
#include <stack>

. . . .

void AstNodeCodeGenerator::visit(StringConst& str) 
{ 
    emit_la("a0", (std::string("str_const") + std::to_string(stringtable().get_idx(str.token.get_val()))).c_str());
}

void AstNodeCodeGenerator::visit(IntConst& int_const) 
{
    emit_la("a0", (std::string("int_const") + std::to_string(inttable().get_idx(int_const.token.get_val()))).c_str());
}

the error is:

error :'to_string' is not a member of 'std' emit_la<"a0",<std::string(("str_const") + std::to_string(stringtable().get_idx(str.token.get_val()))).c_str());

`to_string` is a C++11 feature. You may have to turn that on. — Fred Foo, Mar 04 '14 at 13:56
this is part of makefile:----CFLAGS=-g -Wall -Wextra -std=c++11 -Wno-write-strings ../../include/boost — user3341263, Mar 04 '14 at 14:11

It's not supported on MinGW because of limitations in the MinGW runtime that need changes from MinGW developers.

Take a look at these:

If you can use Boost, a good alternative is boost::lexical_cast (been there, done that).
