error: CYGWIN_NT-10.0-x86_64 is not supported (yet?) on Windows 10

error: CYGWIN_NT-10.0-x86_64 is not supported (yet?) on Windows 10

[John Balkunas]

Hello,

I installed Cywin64 Terminal so that I can compile chrony-4.2 for use with Windows 10 Pro 64-bit. I used the Cygwin Setup program/installer named setup-x86_64.exe for 64 bit Windows.  The install appeared to go well.  After the install, from within the Cywin64 Terminal, I see the following 3 results:

Command: "cygcheck -V"
Result:
cygcheck (cygwin) 3.3.4
System Checker for Cygwin

Thus, this leads me to think everything is ready to go on my Win10 machine for compiling.  However, when I switch to the directory I unpacked the chrony-4.2 to and run the "./configure" command (I used no switches) from within the Cygwin64 Terminal I see the following:

Command: "./configure"
Result:
error: CYGWIN_NT-10.0-x86_64 is not supported (yet?)

I have tried searching for this error (was really hard trying to go through the Cygwin web archives) and haven't seen it discussed.  I am pretty computer literate, but at this juncture I'm not sure how to proceed.  I've compiled a few programs before (from within Linux), have done some programming in the past, but am in no way "comfortable" or that knowledgeable about it and am officially stuck.

ANY responses would likely be appreciated.  Thank you in advance for any help/suggestions/clues!

That message is from chrony, there's no apparent problem with Cygwin. 
The message is just telling you that the OS CYGWIN* is not one known to 
work, or the project being already ported if that is needed.

Perhaps its time to look into configure's options, there may be one to 
(force) build for Linux and, depending on how portable that project is, 
it usually works.

Another detail which is often overlooked, you need to install the 
pre-requisites (listed by the specific project) and its development 
libraries (as in <package>-devel in setup).

Hope this helps.

That is not the same as not supporting Cygwin.

I wouldn't give up, chrony probably works out of the box, it just needs 
to accept that the environment is Linux-like.

You are welcome.

Taken from chrony's FAQ:

"7.1. Does chrony support Windows?

No. The chronyc program (the command-line client used for configuring 
chronyd while it is running) has been successfully built and run under 
Cygwin in the past. chronyd is not portable, because part of it is very 
system-dependent. It needs adapting to work with Windows' equivalent of 
the adjtimex() call, and it needs to be made to work as a service."

Running as a service is not a problem in Cygwin, there's a helper 
program for that.

I'm not sure about the support for adjtimex()... Its not in any header 
so I guess its not supported.  There is an adjtime() in sys/time.h, but 
that is not the same.

BTDT, IIRC too many Linux dependencies.
Still running NTP from Meinberg:

https://www.meinbergglobal.com/english/sw/ntp.htm#ntp_stable
https://www.meinbergglobal.com/download/ntp/windows/ntp-4.2.8p15-v2-win32-setup.exe
https://www.meinbergglobal.com/english/sw/ntp-server-monitor.htm
https://www.meinbergglobal.com/download/ntp/windows/time-server-monitor/ntp-time-server-monitor-104.exe

You can download the sources and build the daemon and utilities with 
older VS releases, but Meinberg provides a service installer and monitor 
utility.

With serial driver and PPS DLL, service and other setup tweaking, you 
can run a serial GPS with PPS at Realtime priority and get microsecond 
stability.

Thank you!  This looks like it may help.
