C++ Threads not working, "error: 'thread' is not a member of 'std'"

I'm going to keep it fast and simple.

Here's the code I've written:

#include <iostream>#include <thread>void myFunc(){    std::cout << "Hello!"<< std::endl;}int main(){    std::thread myThread(myFunc);    myThread.join();    return 0;}

This is the command I've used to compile the program:

g++ threads.cc -o threads.exe -std=c++11

This is the error I'm getting:

threads.cc: In function 'int main()':threads.cc:11:6: error: 'thread' is not a member of 'std'      std::thread myThread(myFunc);      ^threads.cc:13:6: error: 'myThread' was not declared in this scope      myThread.join();      ^

I'm running Windows 10 and as you can see I'm trying to compile the program with GCC.

Can anyone help me with this? I've tried a few different ways to do multi-threading in C++, but none have worked.

The day after tomorrow I'll attend to a programming competition at my school and to make things go faster (the programs may only take up to 5 seconds to process data, which can be a lot) I'm thinking multi-threading could really help. You might think I should know this if I learn programming at school, but I haven't started that course yet and I'm just interested in the competition because it seems fun.

EDIT:

I have now installed the packages "mingw32-libpthreadgc" and "mingw32-libpthreadgce" (both the dev and dll classes). I also installed the "mingw32-pthreads-w32" (dev, doc and lic classes).

I have tried a few different includes <thread>, <pthread>, <pthread.h>. I have also tried adding the flag "-pthread" and "-lpthread". Also, I don't think we'll be allowed to use those flags anyways.

Nothing has worked so far.

I would be awesome if anyone could give a concrete example of which package / packages must be installed, which file / files to include and a short example code (in case mine won't work). We're not allowed to use any libraries except for the standard ones, but running a linux vm is probably fine, so any linux-only example works too.

I haven't found an example like that anywhere yet, so that would be awesome! Thanks!
