C++11 Chrono not working netbeans

I'm trying to use chrono to create my own clocks, but first i'm developing a basic example:

#include <cstdlib>
#include <iostream>
#include <chrono>
#include <ctime>
using namespace std;


int fibonacci(int n)
{
    if (n < 3) return 1;
    return fibonacci(n-1) + fibonacci(n-2);
}


int main(int argc, char** argv) {
   std::chrono::time_point<std::chrono::system_clock> start, end;
   start = std::chrono::system_clock::now();
   int result = fibonacci(42);
   end = std::chrono::system_clock::now();

   int elapsed_seconds = std::chrono::duration_cast<std::chrono::seconds>
                         (end-start).count();
   std::time_t end_time = std::chrono::system_clock::to_time_t(end);

   std::cout << "finished computation at " << std::ctime(&end_time)
          << "elapsed time: " << elapsed_seconds << "s\n";
   return 0;
}

But this simple example doesn't work, I add at Project->Properties->Build-> C++ Compiles and Linker in Aditional Options ' -std=c++11' and still not working

When I running i get:

 RUN FAILED (exit value -1.073.741.511, total time: 2s)
