A question on cygcheck

A question on cygcheck

[Angelo Graziosi]

I have noted that the command

    $ cygcheck -cv > check.out

creates the check.out file in DOS (CR+LF) style.

Is this correct?


Cheers,

    Angelo.

  Same reason as strace, I would assume: it's a DOS-based program, not a cygwin one.

I think you mean "it's a MSVCRT-based program" since DOS hasn't existed
in Windows in the last approx. 7 years.

(And now if I could only get people to stop incorrectly referring to a
NT/2k/XP/Vista command prompt a DOS prompt... and I also want a pony.)

I guess that's one way to describe them. I've heard them described as
"native Win32 console-mode" programs-- I do not know if any of those
exist which are /not/ based on msvcrt so, perhaps these descriptions
are synonymous.

>since DOS hasn't existed in Windows in the last approx. 7 years.

I don't know about the 7 years part (are you saying they no longer
support ME?), but DOS /support/ still exists in XP by way of ntvdm.exe,
the "NT Virtual DOS Machine." I still use a few DOS (full screen
curses-like) utilities that have regretably not been ported to Win32.

I've heard that DOS support is completely discontinued in Vista,
though-- only one of many reasons not to "upgrade."

You don't think big enough. :) I want a percheron-thoroughbred cross
like my last good buddy of that lineage-- 2,000 lbs. worth of quiet
friendship...

I should rephrase for him.  TRUE dos support is non-existant anymore.
This started with Windows XP.  ntvdm as you described is a virtual dos
machine which means it emulates dos.  Windows ME restricted access to it
(you couldn't actually get to a true dos mode).  The whole original
Windows NT line was without any dos support at all.  Not even emulated.
 Check cmd versus command sometime in XP.  You will note that even the
dir command is slower in the ntvdm than it is in a native prompt.

Gotcha, I think: "support"=="TRUE" support==native (not emulated)
support.

I recall reading about that, in the context of "here's how you work
around those annoying restrictions." I used to know how to make 9x both
boot and shut down to a DOS prompt. This was very handy, because even
DOS 7.1 (on which Win 98 was built) still supported many features of
DOS 6, including the config.sys syntax for defining custom boot menus.
There was also a way to disable the startup splash screen in Win 9x so
that you could actually see how your system was booting up... jeez,
listen to me getting all nostalgic... :D

I think I heard that, too. I might've liked to try it, but didn't know
where to get a copy. (I might've liked to try OS/2, for that matter.) I
was new to PC's, and doing well to learn my way around DOS/Win 3.1.

Sure, emulators are usually slower. But it's great to have the
capability to run old familiar comfortable apps for which no suitable
replacement seems available. If I ever decide to bite the bullet and
migrate to Linux/X11, I will definitely want dosemu, and perhaps even
WINE.

BWAHAHAHAHAHAAAHAAAHAAAA... Thanks, I needed that laugh. Sure, why not?
At this point in my life, a dragon seems to be about as much a virtual
creature as a horse. Dogs and cats are good company, until you've been
around horses...

Oh yes! only now I have realized:

$ cygcheck /bin/cygcheck.exe
C:\cygwin\bin/cygcheck.exe
   C:\WINDOWS\system32\msvcrt.dll
     C:\WINDOWS\system32\KERNEL32.dll

Thanks,

Re: A question on cygcheck

Angelo, think about. Of course it's native windows program without any 
dependency on cygwin1.dll. It's supposed to be able to inspect your 
cygwin installation even when it's so hosed that you can't even launch a 
bash shell. Thus, it's a pure windows program and generates line breaks 
the way all windows programs do.

I only use 'cygcheck' that comes with Cygwin!

Does this mean that the 'cygcheck' has used MSVCRT-based program
to build it?



Cheers,
