Compile win64 filesys kernel module only with Cygwin tools?

Compile win64 filesys kernel module only with Cygwin tools?

[Wendy Lin]

How can I compile
https://github.com/microsoft/Windows-driver-samples/tree/main/filesys/cdfs
with Cygwin gcc?

Compiling the individual *.c files might be easy, but how do I LINK
this to a *.sys module which can be loaded into the Windows 10 64bit
kernel?

You should not be trying to do that.

That's deeply system-specific Windows code.  It has nothing to with 
POSIX, Cygwin or anything like that.

For that you need a native Windows toolchain, and quite possibly some 
extra SDK packages from Microsoft to enable building them.  MinGW64 
(wether stand-alone, or the MSYS(2) hosted one, or the one hosted in 
Cygwin) might be able to do it.

I really don't care. I really want to RUN AWAY (CRYING!!) from having
to depend on Visual Studio 2019 or later. I can't even find C:\WinDDK\
with Visual Studio 2019 anymore, after updating from Windows 8. I'm
almost crying about it.

Also, we want CI, and that is not going to happen with the Visual
Studio Community edition.

So, MinGW64 would work? Which compiler and linker options do I have to
use, which libraries do I link against etc?

I'd be very interested in this idea to (build *.sys kernel module with
minGW64). Has anyone ever tried to do that? Just from Googling PDB
(Windows Debug File Format) files will be absent, but that is all,
right?

Thanks,
