Does MinGW-w64 with the Win32 threading model support std::thread natively?

Does MinGW-w64 natively support std::thread with Win32 threading model?

When using the MinGW-w64 toolchain, selecting the Win32 threading model may raise concerns about the availability of C 11 thread support.

Initially, it was believed that std::thread could be used regardless of the threading model based on previous statements. However, that assumption proved incorrect.

Despite invoking g with -std=c 11, std::thread remains unsupported. The options to reconcile this discrepancy are:

• Misinformation: The initial assumption that C 11 threads would work with the Win32 threading model was incorrect.
• Misunderstanding: Despite inquiries, it's still unclear whether std::thread support exists in this scenario.
• Support but with unexpected implementation: std::thread may be supported but not in an intuitive manner.

However, the "out of the box" qualification in the question excludes third-party options like mingw-std-threads.

Native std::thread Support

As of May 2016, native std::thread support in MinGW-w64 with the Win32 threading model is achieved by installing the mingw-std-threads headers.

This is because MinGW-w64 lacks native thread support like other GCC installations that implement threading via gthreads or pthreads. MinGW-w64 also lacks a glibc port but uses MSVC runtime and its own code to fill in missing components.

Recent versions of MinGW-w64 include a Win32 port of pthreads ("winpthreads"), which explains why selecting the "pthread" model during installation enables threads.
