I found this at the cygwin-ug:
http://cygwin.com/cygwin-ug-net/setup-dir.html
'You do not need to create /dev in order to set up mounts for devices
such as /dev/null as these are already automatically simulated inside
the Cygwin library.'
But i got always errors from dejagnu accessing dev/null:
# of unexpected failures 2
WARNING: find_version failed:
couldn't read file "/dev/null": no such file or directory
make[3]: *** [check-DEJAGNU] Error 1
I created a dev/null, but then i got this error:
# of unexpected failures 2
WARNING: find_version failed:
couldn't read file "/dev/null": permission denied
make[3]: *** [check-DEJAGNU] Error 1
How to set up dejagnu or cygwin to handle this?

How did you setup the /dev/null?
I can't get `mknod' to work. I always get 'function not supported'.
And the flags - are they BSD compatible?

Right. mknod is not implemented. That's what the error means.
/dev/null is intrinsic to cygwin1.dll. Cygwin programs can use it
automatically, just like they can use /dev/tty, /dev/mem, /dev/kmem,
etc.

It was just a try of me as i didn't get dejagnu to run. Normally,
/dev/null is emulated inside cygwin and you don't need to set it up.
I was a little blue-eyed, i made this as a directory, just with
windows-explorer, but it didn't solve my problems.
Try to ask again, with mknod as subject content.

Since /dev/null is not a directory that is hardly surprising.

Or, read the answer that I already provided.

One thing that I have not read anybody explain yet, in this thread: the
WinDOS system counterpart to UNI* 'dev/null' is simply 'nul' (or 'NUL'). If
you need a null file to redirect IN to a command I guess you'd use that. I
never try to redirect out to /dev/nul in Cygwin or otherwise, anyway --
although scripts generated by others need to be accomodated. But
manually, I just use 'nul'.

/dev/null in cygwin eventually translates to the Windows NUL device.
There is no reason to use 'NUL' rather than '/dev/null' since they are
both the same thing ... unless you enjoy using MS-DOS constructs rather
than UNIX ones. That's sort of anti-Cygwin, though.

I figured.

NO! NO! I am not anti-Cygwin ;-). I LUV Cygwin.
As a background general-knowledge sort of thing, I think its good to know
this. Allegory ... if you were stranded on a desert island with no way to buy
tiolet paper, would it be good to know how to make plant leaves very soft ..
? Someone might someday be working out a problem without Cygwin
around. I don't WISH it on them, but it could happen.
Cheers,

Hopefully these people are reading the appropriate mailing lists and
newsgroups for non-cygwin problems, then.
In general, I think it is a good idea to use cygwin constructs as much
as possible. Then, if/when we modify cygwin so that it can work around
the brain-dead, nul, com, aux, prn stupidity foisted on us by Windows'
MS-DOS roots, people won't be scratching their heads thinking "But I
read that 'NUL' should work fine in the cygwin mailing list."
