Hello all,

I'm still having this problem but I'm beginning to narrow it down.
 
Here's an example of the error I get:

"J:\trunk\svn\apl\win\bin\mk_cc:
/cygdrive/j/trunk/svn/apl/allos/bin/verbose: /usr/bin/sh: bad interpreter:
Permission denied"

I've upgraded to cygwin 1.7, and I'm running this on Windows 7 x64. Cygwin
is installed on the local C drive. I've removed all anti-virus software.

It seems that I only get this sporadic (and incorrect) "bad interpreter"
message if my scripts are located on a mounted SAMBA drive. If I move all
the scripts to my local drive the access problem goes away, but I want to
keep them on the remove drive. If I run my make task with a single job (-j1)
the problem goes away.

Here's my mount output

C:/cygwin/bin on /usr/bin type ntfs (binary,auto)
C:/cygwin/lib on /usr/lib type ntfs (binary,auto)
C:/cygwin on / type ntfs (binary,auto)
C: on /cygdrive/c type ntfs (binary,posix=0,user,noumount,auto)
D: on /cygdrive/d type ntfs (binary,posix=0,user,noumount,auto)
I: on /cygdrive/i type smbfs (binary,posix=0,user,noumount,auto)
J: on /cygdrive/j type smbfs (binary,posix=0,user,noumount,auto)
M: on /cygdrive/m type smbfs (binary,posix=0,user,noumount,auto)
U: on /cygdrive/u type smbfs (binary,posix=0,user,noumount,auto)
Z: on /cygdrive/z type ntfs (binary,posix=0,user,noumount,auto)

My scripts are located on /cygdrive/j which cygwin has auto-mounted from my
J: drive, which I'd previously (using Windows) mapped from our SAMBA server.
I've experimented with acl/noacl but that seems to make no difference, and
to be honest, I'm sort of guessing a bit. 

I also thought I try mapping the relevant drive directly (ie //devt/files on
/cygdrive/j) to remove the intermediate use of "J:", but I can't find out
how to prevent cygwin from automatically mounting all my drives.

I've also been trying to build a local cygwin so I can try to debug the
problem, but I can't get the build process to complete (see
http://article.gmane.org/gmane.os.cygwin/111950) 


Does anyone have any tips, or things I can try in order to get this to work?


Thanks,
John.

Hi Jurriaan,

I've tried that, completely removed my Sophos anti-virus. I'm still getting
the same problem.

You're not running something like a virus scanner, are you? I know my
scripts throw some strange errors when McAfee is running. Why these
errors mostly happen at night while I'm in bed, I'm not sure. However, I
do know that since I've disabled McAfee, I sleep a lot better since work
never calls in the middle of the night.

HTH,
Jurriaan
