I am trying to compile a code taken from std::this_thread::sleep_for()

#include <iostream>
#include <chrono>
#include <thread>

int main()
{
    using namespace std::chrono_literals;
    std::cout << "Hello waiter" << std::endl; // flush is intentional
    auto start = std::chrono::high_resolution_clock::now();
    std::this_thread::sleep_for(2s);
    auto end = std::chrono::high_resolution_clock::now();
    std::chrono::duration<double, std::milli> elapsed = end-start;
    std::cout << "Waited " << elapsed.count() << " ms\n";
}

When I try to compile the code I get the following error

error: 'std::this_thread' has not been declared

My GCC version is 6.3.0.

How can I compile? Any idea?

Please post a [mcve] (don't forget the *minimal* part), including your compiler invocation command line. Are you including the necessary header(s)? – Angew is no longer proud of SO Dec 29 '17 at 13:18

Did you compile with -std=c++11 or 14? – Incomputable Dec 29 '17 at 13:30
What platform are you compiling on? – TriskalJM Dec 29 '17 at 14:17
