build mingwpy with "posix" thread model?

[Cosimo Lupo]

Hello,

I need to cythonize a C++ library which uses C++11 threading (std::thread, std::async, etc.).

I can compile the DLL using the mingw-w64 gcc configured for "posix" thread model (as available from MSYS2). However, if I try to use mingwpy, it fails because the latter is compiled with "win32" thread and as such has no C++11 threading support.

Sorry if my question sounds naive questions. Could you please remind me why mingwpy is compiled with "win32" threads instead of "posix" by default? And what are the problems if I use the posix version of mingw gcc to compile my extension modules and supporting libraries?

Thank you,

I also found this https://github.com/meganz/mingw-std-threads

It's an implementation of the C++11 threading for MinGW GCC built with "win32" (not "posix") threads.

(though it doesn't seem to support std::async)

There is alo an even more ambitious project: mcfgthread, but right now also without C++0x thread interfaces. Hopefully at some point it is possible to overcome the conceptional thread implementation schism.

Right now I don't intend to change mingwpy to the so-called posix threads model, as it slows down windows threads handling. This may change in future, but needs more time for testing and benchmarking numpy/scipy and others.

Cheers
