CYGWIN UNIX FILE PATH LEAVES FILES UNDELETABLE THROUGH WIN7

CYGWIN UNIX FILE PATH LEAVES FILES UNDELETABLE THROUGH WIN7

[Richard Stern]

I'm a new user and just recently tried to install 
cygwin 1.7.5, after installing JAVA NetBeans.

I wanted to install the C++ packages along with 
Python. Below is a sample of what occurred. copied 
from
the output of... cygcheck -s -v -r > cygcheck.out
                    -----------------------------
2010/08/08 06:44:15 running: 
D:\Cplus\bin\bash.exe --norc --noprofile 
/etc/postinstall/gcc4-core.sh
2010/08/08 06:44:19 abnormal exit: exit code=126
2010/08/08 06:48:34 running: 
D:\Cplus\bin\bash.exe --norc --noprofile 
/etc/postinstall/gtk2.0.sh
2010/08/08 06:48:44 abnormal exit: exit code=127
2010/08/08 07:11:53 running: 
D:\Cplus\bin\bash.exe --norc --noprofile 
/etc/postinstall/post-texmf.sh
2010/08/08 07:40:39 can't run 
/etc/postinstall/post-texmf.sh: No such file
2010/08/08 07:41:00 running: 
D:\Cplus\bin\bash.exe --norc --noprofile 
/etc/postinstall/gcc4-core.sh
2010/08/08 07:41:03 abnormal exit: exit code=126
2010/08/08 07:41:03 running:

/etc/postinstall/gtk2.0.sh
2010/08/08 07:41:12 abnormal exit: exit code=127
2010/08/08 07:41:12 Changing gid to Administrators
2010/08/08 08:25:10 note: Installation Complete
2010/08/08 08:25:10 Ending cygwin install
                -----------------------------
I had uninstalled the total cygwin package by 
deleting all the directories made for this software, 
because cygwin did not show in the list of installed 
programs
in the "Control Panel" utility "Programs & Features" 
in Windows 7 OS. After the deletions, only one 
directory and file were unable to be deleted,
the file named " nul " in the directory " dev ". A 
popup window notified me of the problem but was not 
specific.
After much brainstorming, I booted up into a LINUX 
environment, located the /my Cplus dir/dev/nul 
directory
and file. Using the file manager, I was able to 
delete the items.

I have read & browsed much of the documentation, at 
the moment, that's possible and tried to be sure 
this issue hasn't been covered.
I believe that is the case. I'm a retired NASA 
contractor. UNIX System Administrator for Real-Time 
Systems being one of my task, I hope
this has given me enough knowledge to know when I 
need further assistance.

I tried to subscribe to the cygwin.com mailing list. 
But the email returned with an unknown address 
error. I have recheck this address
cygwin-subscribe@cygwin.com and still returns a 
failure notice.

Thank You for your time for reading this and any 
assistance you may offer.

See http://www.cygwin.com/ml/cygwin/2010-04/msg01047.html for
suggestions on why you are getting the abnormal exit codes.  Also,
this http://www.google.com/search?q=site%3Acygwin.com%20inurl%3Aml%2F%20abnormal%20exit

I don't know why are having problems subscribing to the list.

I don't know why you had the problem with /dev/nul

This is well known (if you're an old timer - think cp/m, then DOS)  as
it's a reserved word. CON: NUL: LPT!: are all examples of this. The
solution is easy:

:: for files
del \\.\c:\cygwin\dev\nul
:: for dirs
rd \\.\c:\cygwin\dev\con
