Building on Windows 7 requires using proper toolchain, old CPython and old MSVC compilers

Hello, I like the new option. I am testing compatibility according to Windows version. I used the --onefile option, but there was an error in Windows 7.

Env

0.6.10 Python: 3.9.1 (tags/v3.9.1:1e5d33e, Dec 7 2020, 16:33:24) [MSC v.1928 32 bit (Intel)] Executable: C:\Python\python.exe OS: Windows Arch: x86

NUITKA v(0, 6, 10) on Python 3.9.1 (win32) is compiling 'C:/Users/MK/Desktop/Py_Project/test.py' with these options:
 --standalone
 --recurse-none
 --hinted-json-file=C:/Users/MK/Desktop/Py_Project/test-39-win32-32.json
 --plugin-enable=qt-plugins
 --include-qt-plugins=sensible,styles
 --remove-output
 --windows-product-version=1.0.0.0
 --windows-company-name=MK
 --windows-file-description=MK
 --output-dir=../Nuitka
 --onefile
 --windows-icon-from-ico=exe.ico

test.py

import pathlib
print(pathlib.Path(__file__))
input()

Result

Windows 10 x32 : OK Windows 10 x64 : OK Windows 7 x32 : Error

OK, after a few tests, the last working WinPython for Win7 is WinPython_3.6.3.0: https://github.com/winpython/winpython/releases/tag/1.9.20171031 Both pip and nuitka work without any problems. Unfortunately, we have a slightly older version of python and we have to be careful with the commands we use, but if someone really cares about the portable version for Win7, they have a hint ready.

Thanks for the tips.

@Pro100rus32 love you for that, I will add it to the docs, I knew it in theory, but it’s easy to not have it on your mind.

As for mingw, do not install it, let Nuitka download it for you. Just don’t have it in PATH.

And from the Executable: output, that is just plain sys.executable and indicative of your Python not feeling at home on that OS, or not with the installation path it is finding itself in. You might have to go back further. Or at least, you might have to install to something that doesn’t contain anything that is not ASCII.

Ah, and don’t use WinPython, it might be gargage or more aggressive about Windows 7 support, or… I considered checking out, if Nuitka supports it, but right now it does not. Use CPython or Anaconda, those I know work.
