Hi Cygwin,
I’ve studied Cygwin.Com for 7 days and found several technical errors
affecting your primary keywords: Cygwin Linux tools, POSIX API Windows, GNU
utilities collection ranking, impacting The Cygwin Project’s online
presence in the post-pandemic market.

We're working on that. LLVM 21.x should be much better in that regard.
There has been no effort towards aarch64-pc-cygwin though

Yes, but as others have said it is too slow to really be practical.

Cygwin creates instead of on NTFS, but cmd.exe
cannot find the *.exe if they are linked as .
Two test cases:

ln -sf id_vers15.exe myid.exe ; cmd /C \'.\myid.exe\''

IMO someone at Microsoft engineering management should look at the
issue that Windows-11 does not work on qemu.
Right now there are no ARM64 builds

Hello,
I downloaded the ISO for Windows on ARM64 from Microsoft site and I
installed it with QEMU, but it is absolutely unusable. For example, if you
click on the start button, the menu start to open after 10 seconds. You can
go to tale a coffee if you try to open notepad for example. It happens al

Hello.
We have never considered QEMU as an option so I can't tell whether it's working.
We are testing the Cygwin runtime and the GCC toolchain linked with it built
with Linux->Windows cross-compiler on self-hosted GitHub Actions runner running
on Windows Arm64 VM with WSL leveraging WSL intero
Hello Sebastian.
AFAIK, LLVM has no *-pc-cygwin targets support and there is no-one trying to
change that.
The best take you can have for now is to build your own GCC Linux to Windows
cross-compiler using
https://github.com/Windows-on-ARM-Experiments/mingw-woarm64-build scripts or
download it
Does Cygwin /usr/bin/clang has Aarch64 support, to compile native
Windows Aarch64 binaries if Cygwin-x86-64 runs on Windows Aarch64?

Check the cygwin-patches mailing list, and the cygwin git log. Lots of
Aarch64 related patches.

Thanka for the head up - can you provide us with a pointer to Microsoft
work on Cygwin please?
On a Raspberry Pi 5 "botspot-VM" https://github.com/Botspot/bvm installed
a Win11 for me fairly happily and despite it not being the fastest machine
it is closer to viable than I might have expected
Now that Microsoft is porting Cygwin to Aarch64:
Do you know how to run Windows Aarch64 in qemu, so people can test
Cygwin Aarch64 changes?
