What version of visual studio are you using?

Visual Studio 2022, aka 17.6.2.

What version of python?

python 3.10.11 or 3.11.4

I’ve had success with using the cython package in python and cl from visual studio, but I haven’t tried visual studio alone.

Same problem at the same place: directory "../modules/..." not found, Renaming it from "Modules" to "modules" it is found, but then fails to find "Modules". Looks like it awaits, compiling in Windows an filesystem only case aware, not case sensitive -- I'm assuming this a bug now. Building within cygwin (or MSYS, Ubuntu) this works as expected. But there it does not search for "modules" once and "Modules" at an other place.

I just did this build the other day for the first time even from a git checkout (so VS22, and not a versioned release but top of main branch), and there was no such problem - did you follow the instructions at https://devguide.python.org/getting-started/setup-building/index.html?

Yes.

Had git installed (2.41.0.windows.1), did "git clone https://github.com/python/cpython.git";, then checked out the branch I wanted: "git checkout 3.10.12" (or 3.11.4, 3.12.0b2).

Python was already installed and in path:
"python --version" gives back: "Python 3.11.4"





"fsutil.exe file SetCaseSensitiveInfo <path> enable"

You may query this with:

"fsutil.exe file queryCaseSensitiveInfo <path>"

In my case:
~/Documents/Projekte/cpython> fsutil.exe file queryCaseSensitiveInfo .

Changed into cpython directory, then called: ".\PCbuild\build.bat" (".\pcbuild\build.bat" will, within cmd.exe, throw an error: File not found -- remember directory cpython and all beyond are case sensitive, not only case aware -- git sets case sensitiveness for checked out directories). It compiles until it does not find "modules", because the directory is named "Modules" (all posix file systems behave this way and NTFS can be forced to behave this way too. It is easy and any user can do it: Or: the directory we're in is case sensitive and distinguishes between "Modules", "modules" and "MODULES" and you can have them all: Since case sensitivity is necessary for a variety of projects normally only used with *nix-OS I've configured git to create directories with case sensitivity set enabled (its default meanwhile if git is installed on windows).
