Hi,
I'm writing an application in C that's increasingly dependent on the POSIX
APIs and would like to use the Cygwin DLL to help port it to Windows. I
currently use MinGW-w64 but foresee that will stop being sufficient eventually.
I want to do this using only free software without a Windows installation. A
GNU/Linux to Cygwin cross compiler doesn't seem available, at least on Debian.
Cygwin also fails to run under Wine.
I'm not interested in the Cygwin userspace, I just need the POSIX layer. Aside
from booting up a ReactOS VM, is there a more clean way to do what I seek to
do?
Thanks,
John

Should work as there are fixes in each for the other.

There's a Fedora->Cygwin cross environment documented in:
https://cygwin.com/pipermail/cygwin/2020-July/245695.html
or your local copy from July 27-28.

I tried this a while back too, before I gave up and used a Windows VM.
Cygwin currently doesn't seem to work in wine, sadly. It does almost
work though, by the looks of it. I'm going to see if I can report some
bugs on WineHQ if any of the Wine developers are interested.

So I reported that it doesn't work on WineHQ, and there was a helpful comment that suggests recompiling WINE with a patch can get it working.
Here are the links, hopefully this isn't too late to be useful:
