  1. We have the MinGW-W64 that is a fork of MinGW that supports those features and I was wondering, which one to use? Knowing that GCC is one of the most used C++ compilers. Or it's better to use the MSVC (VC++) on Windows and GCC on Linux and use CMake to handle with the independent compiler?

  2. Some software only supports MSVC on Windows (e.g. CPython, including native modules) so you may have to use it. The only advantage is that you get a statically-linked CRT — versus linking against an old msvcrt.dll per Mingw-w64 — though historically Microsoft's UCRT has been kind of buggy, and those bugs then get baked into your binaries.

  3. Initially I ran into some issues with x64 and certain functions (std::stoi, std::to_string) as well as support for certain exception models. If I understand correctly the mingw project is a bit slow and got forked and mingw-w64 has become the sensible choice, solving most of those problems.

  4. MSVC is doing the compilation job significantly faster than MinGW-w64. The DLL sizes are comparable, if optimization is set to "-O2" for MinGW-w64, with "-O3" the DLLs from MinGW-w64 are larger. Binary files compiled with MinGW-w64 are performing significantly better than those compiled with MSVC.

Binary files compiled with MinGW-w64 are performing significantly better than those compiled with MSVC.

  6. Some alternative compilers exist like MinGW, but incompatibilities may occur with a CPython official distribution that is built with Microsoft Visual C++. The compiler's architecture must be the same as Python's (for example: if you use Python 64bit, you have to use an x64 compiler).
