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

Question

I try to use std::this_thread::sleep_for() function but got the error
error: 'std::this_thread' has not been declared.
The flag _GLIBCXX_USE_NANOSLEEP included.
What else is needed to force it to work?
MinGW ==> gcc version 4.7.2 (GCC)

SSCCE:

#include<thread>

int main() {
  std::this_thread::sleep_for(std::chrono::seconds(3));
}

command line:

g++ -D_GLIBCXX_USE_NANOSLEEP -std=gnu++0x ssce.cpp -o ssce.exe

result of compilation:

ssce.cpp: In function 'int main()':
ssce.cpp:4:8: error: 'std::this_thread' has not been declared

Please present a real testcase, so your ten-line example C++ program and your build command. — Lightness Races in Orbit, Dec 06 '12 at 10:35
@OlegG there probably is a way to make that work, just search around a bit and you will probably find quite a lot on this topic. — Stephan Dollberg, Dec 06 '12 at 11:18
Is boost::threads an option for you? The functionality should be similar enough. Otherwise you could write `sleep_for` on basis of e.g. pthreads. If you are interested I think I might still have the source for the later lying around somewhere from when I ran into the same problem. — Grizzly, Dec 06 '12 at 18:36
@Grizzly: Actually I've overcome this using boost. Right like you said. But I want to use std everywhere it is possible. Thanks for the suggestion. — OlegG, Dec 07 '12 at 06:52

Use MinGW with POSIX threads, Luke.

thank you! The compiler being MinGW made the difference. – asgs Nov 07 '15 at 18:49

I don't understand this answer at all. The asker is *already* using MinGW. It's MinGW that is causing this problem in the first place. Also, that is not the link to MinGW. It should be: https://sourceforge.net/projects/mingw/. – Boann Feb 26 '18 at 22:00

mingw w64 apparently has two modes: https://stackoverflow.com/questions/37358856/does-mingw-w64-support-stdthread-out-of-the-box-when-using-the-win32-threading – rogerdpack Feb 06 '19 at 05:37
