Building python from source for MSI installer

Python Help
1

I’m able to build whole project with Visual Studio 2022 but cannot with command line, buildrelease.bat. Also tried with retarget solution but no hope.

I’m trying to build python-3.12 NOGIL version

Here is the error message you are getting.

Use the Visual Studio installer to install the current version of MSVC, or else set PlatformToolset environment variable to whatever version you have installed (e.g. like v142 if you have 14.2 installed).

Oh, it’s probably because there’s no 3.12 nogil version. Try building from the main branch of the repository, or using a 3.13 release tarball instead.

I download the source from here GitHub - colesbury/nogil-3.12-final: Multithreaded Python without the GIL (experimental rebase on 3.12 final)
i thought it’s official nogil. I success build it. thanks in advance

Official releases come from python.org, nowhere else. Sam’s fork probably never updated the installer code.

Get the source tarball from Python Release Python 3.13.0b3 | Python.org or follow the link to instructions on how to get the free-threaded (formerly known as “nogil”) build from the installers.
