I don't think Windows has its own package management for Python packages. I'd be totally surprised. The python packages found at https://www.python.org/downloads/ come with pip and pip installed out of the box.

Possibly you have a setting configured that affects the behavior of Git via the MinGW-w64 runtime, such that calling mkdir() ends up calling NtSetInformationFile() to set the FileCaseSensitiveInformation for the directory. It is a mount option for MSYS or cygwin controlled parts of the file system. posix=1 switches case sensitivity on, posix=0 switches it off. MSYS or cygwin are then make caseSensitiveInfo "inheritated" by setting this flag for all newly created directories. This is a feature of the latest cygwin-dll. It might not be seen on older variants. Does the mkdir command in Git bash create a case-sensitive directory? It doesn't for me. I have to manually enable case sensitivity via `chattr +C`. What do you get for `which git` and `git --version`? $ which git /mingw64/bin/git $ git --version git version 2.41.0.windows.1 the same: $ which git /mingw64/bin/git $ git --version git version 2.41.0.windows.1 And in cmd.exe: +>where git C:\Program Files\Git\bin\git.exe +>git --version git version 2.41.0.windows.1 $ fsutil file queryCaseSensitiveInfo . The MSYS2 environment includes lsattr and chattr commands, with the case-sensitive flag mapped to "C". It's probably more convenient than typing `fsutil file queryCaseSensitiveInfo` or `fsutil file setCaseSensitiveInfo`. $ lsattr -d test test $ chattr +C test $ lsattr -d test ---C test True. But if you frequently change between environments fsutil is the command working in cmd.exe as in git-shell. core.ignorecase is not regarded in any way. It does not mater if it is set or not. Git tests the case-sensitivity of the target directory to configure core.ignorecase when cloning a repo. If it's case insensitive, then core.ignorecase is enabled. This overrides the global value. AFAIK, the ignorecase setting is unrelated to actually setting the case sensitivity of created directories; it just affects how Git behaves on a case-insensitive filesystem. -- Thomas OpenPGP_signature Description: OpenPGP digital signature -- https://mail.python.org/mailman/listinfo/python-list

And Windows enabled case sensitivity for all new directories under the directory. No. This flag is not inherited. Someone has to set it for created directories. It is easy to confirm: take a directory not under MSYS or cygwin control (because it is mounted by MSYS or cygwin), set the flag, then create directories. They all will have caseSensitivInfo disabled. Since it is not default and minor setting, it is not a bug that current Python doesn't support building on case sensitive directory. But I think it is a nice improvement if next Python supports it. Python itself isn't the problem here. It is MSBuild.exe. For some reason this tool lowercases sometimes whole paths to files included. This does not matter if case sensitivity is disabled. It matters if case sensitivity is enabled! There is no reason MSBUild.exe does it. But it is done for some paths (as someone else pointed out).

As far as I know, `git config core.ignorecase` doesn't mean NTFS case
sensitive.
If a repo is cloned into a case-insensitive directory, then
core.ignorecase should be enabled automatically. If a repo is cloned
into a case-sensitive directory, then core.ignorecase should not be
enabled automatically.
I searched through relevant issues on the Git for Windows repo on
GitHub, and I found nothing to indicate that a capability to
automatically enable NTFS case sensitivity has been added. I searched
through the source of Git and Git for Windows, and I didn't find any
references to WinAPI SetFileInformationByHandle: FileCaseSensitiveInfo
or NTAPI NtSetInformationFile: FileCaseSensitiveInformation, nor the
use of fsutil file setCaseSensitiveInfo.
In this case: not sure what is going on. In a git-shell on Windows:
If caseSensitiveInfo is disabled:
user@host MINGW64 ~/K
$ fsutil file queryCaseSensitiveInfo .
Das Attribut für Groß-/Kleinschreibung für das Verzeichnis
"C:\Users\user\K" ist deaktiviert.

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"
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:
"fsutil.exe file SetCaseSensitiveInfo enable"
You may query this with:
"fsutil.exe file queryCaseSensitiveInfo "
In my case:
~/Documents/Projekte/cpython> fsutil.exe file queryCaseSensitiveInfo .
Das Attribut für Groß-/Kleinschreibung für das Verzeichnis ^
"C:\Users\user\Documents\Projekte\cpython" ist aktiviert.
Or: the directory we're in is case sensitive and distinguishes between
"Modules", "modules" and "MODULES" and you can have them all:
C:\Users\user\Documents\Projekte\cpython>dir
Datenträger in Laufwerk C: ist Windows
Volumeseriennummer: BC5E-F466
Verzeichnis von C:\Users\user\Documents\Projekte\cpython

Mo, 12.Jun.2023 22:13 Modules

[...]
16 Datei(en), 1.320.340 Bytes
21 Verzeichnis(se), 134.699.622.400 Bytes frei
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).
