mingw 5 std :: this_thread未定义

Question

Hi any body try to use header support mingw w64?

main.cpp: In function 'int main()':
main.cpp:9:10: error: 'std::this_thread' has not been declared
std::this_thread::sleep_for( dura );
      ^

I got above error with following simple test

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

int main()
{ 
 std::cout << "Hello waiter" << std::endl;
 std::chrono::milliseconds dura( 2000 );
 std::this_thread::sleep_for( dura );
 std::cout << "Waited 2000 ms\n";
}

I want to use lastest N3653 and N3651 as spesified here https://gcc.gnu.org/projects/cxx1y.html and of course threading support header , using someone builds found here http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win64/Personal%20Builds/dongsheng-daily/5.0/ and my c++config.h _GLIBCXX_USE_NANOSLEEP is not defined , any idea?

[EDIT] I realize that my thread model was: win32 and not posix one. How to enable posix support?

You can use update-alternatives for i686-w64-mingw-g++ and set it to i686-w64-mingw-g++-posix from i686-w64-mingw-g++-win32 .

Or you can just use i686-w64-mingw-g++-posix to compile. There are other versions so in this case you'd use the 64 bit compiler instead and append the -posix to it.
