I would like to compile my c++11 project (recently moved to c++11) with MinGW. And I have compiling errors about c++11 code like "std::thread not found".
I used the last MinGW with gcc 5.3.0 (December 2015). A the end, I would like only to compile this example before to compile my big project :
#include <iostream>
#include <thread>
#include <chrono>
void foo()
{
    // simulate expensive operation
    std::this_thread::sleep_for(std::chrono::seconds(1));
}
void bar()
{
    // simulate expensive operation
    std::this_thread::sleep_for(std::chrono::seconds(1));
}
int main()
{
    std::cout << "starting first helper...\n";
    std::thread helper1(foo);
    std::cout << "starting second helper...\n";
    std::thread helper2(bar);
    std::cout << "waiting for helpers to finish..." << std::endl;
    helper1.join();
    helper2.join();
    std::cout << "done!\n";
}

I tried "g++ -std=c++11 main.cpp" and "g++ main.cpp -std=c++0x" but I have always those following errors :
main.cpp: In function 'void foo()':
main.cpp:8:10: error: 'std::this_thread' has not been declared
     std::this_thread::sleep_for(std::chrono::seconds(1));
