got a very odd problem that's driving me nuts.
in cygwin prompt, i can call one of imagemagick's command and get
result.
However, while in emacsw32 shell, identical call results Windows Vista
poppig up a window telling me some app crashed.
Anyone got some idea what's wrong?
-----------------------------------
here's more precise detail.
Here's how i call a program in cygwin terminal:
xah@xah-PC ~/web/dinju/i
$ convert Bazaar_zanjan.jpg Bazaar_zanjan.png
the above converts a jpg image to png, successfully.
Here's how i call it in emacsW32. In dired, cd to the dir, then Alt+x
shell, then “convert Bazaar_zanjan.jpg Bazaar_zanjan.png”.
Then, Windows pops up dialog about “convert.exe has stopped working”
with the following error:
Problem signature:
Problem Event Name: APPCRASH
Application Name: convert.exe
Application Version: 0.0.0.0
Application Timestamp: 4807a468
Fault Module Name: cygX11-6.dll

Additional Information 3: 9d13
Additional Information 4: 1abee00edb3fc1158f9ad6f44f0f6be8
this popup repeats 6 times.
Same thing happens if you simply call “identify” without running any
arguments, with about the exact same error message. e.g.
Problem signature:
Problem Event Name: APPCRASH
Application Name: identify.exe
Application Version: 0.0.0.0
Application Timestamp: 4807a46a
Fault Module Name: cygX11-6.dll

Additional Information 3: 9d13
Additional Information 4: 1abee00edb3fc1158f9ad6f44f0f6be8
“identify” is another command in imagemagick, it works fine if called
in cygwin terminal. Here's the log:
xah@xah-PC ~/web/dinju/i
$ identify Bazaar_zanjan.jpg
Bazaar_zanjan.jpg JPEG 450x445 450x445+0+0 DirectClass 8-bit
65.793kb
------------
Cygwin has been re-installed many times in the past 2 weeks. I was
able to run imagemagick commands within emacsW32 before without a
problem. The problem happened with my last reinstall of cygwin.
the odd thing is that it runs fine within cygwin terminal. I thought
maybe i'm missing some component in cygwin, but don't know which X11
related package corresponds to cygX11-6.dll. I thought maybe i had
some bad path setup in emacsW32, but went thru all my emacs init files
couldn't identify it. Same problem happens if i run emacs with -q,
then manually set-variable w32shell-cygwin-bin to “"C:\\cygwin\\bin"”
and w32shell-shell to “cygwin”, then run my command.
any suggestions?
Thanks.

Different paths. At the cygwin prompt you have imagemagick's
convert.exe first in path.
At a cmd prompt you by default have windows convert.exe in the path.
(There is a which utility you can get from gnuwin32.)
So I do not think this is related to EmacsW32. If it is then please
give me more information.

Hi Len,
Thanks! You solved my problem.
I'm aware of Window's convert.exe ... my path problem is a bit
subtle... but from youp reply, i compared my $PATH in cygwin terminal
and $PATH in emacsW32's cygwin-shell, seeing that they are different,
then i set emacsW32's cygwin-shell's $PATH to the same as the $PATH
shown in cygwin terminal, then the problem is solved.
For the record, here's the value of $PATH in cygwin terminal
(reformatted for readibility):
/usr/local/bin
/usr/bin
/bin
/usr/X11R6/bin
/cygdrive/c/Windows/system32
/cygdrive/c/Windows
/cygdrive/c/Windows/System32/Wbem
/cygdrive/c/hp/bin/Python
/cygdrive/c/Program Files (x86)/ATI Technologies/ATI.ACE/Core-Static
/cygdrive/c/Program Files (x86)/QuickTime/QTSystem/
Here's the value of $PATH in emacsW32 cygwin-shell:
/usr/bin
/cygdrive/c/Program Files (x86)/Emacs/emacs/bin/
/cygdrive/c/Program Files/Microsoft IntelliType Pro/
/cygdrive/c/Windows/system32
/cygdrive/c/Windows
/cygdrive/c/Windows/System32/Wbem
/cygdrive/c/hp/bin/Python
/cygdrive/c/Program Files (x86)/ATI Technologies/ATI.ACE/Core-Static
/cygdrive/c/Program Files (x86)/QuickTime/QTSystem/
The interesting thing is that imagemagick's convert is in /usr/bin,
so, while in emacsW32's cygwin-shell, i can do “which convert” and it
reports the right program. So, apparantly, subsequent paths much have
fucked things up. This probably also mean that /usr/bin/convert relies
on other pieces to work. (same goes for imagemagick's “identify”
command.)
Thanks again Lennart. I owe you one.
Xah

Good. Now perhaps you could help me solve mine ... ;-)
The path in cygwin was not setup correctly cygwin-shell (which I ought
to rename). I have tried to fix that, but could not get it entirely
correct (probably a cygwin bug, I have asked them right now).
Could you please try the attached version of w32shell.el and see if
that works for you without you having to change the paths yourself?

;;; Commentary:
;;
;; On w32 you sometimes need an inferior shell like GNU bash for
;; installations and other purposes. (Note: An "inferior" process in
;; Emacs is a subprocess.) You may also need to have the Emacs bin
;; directory in path at the same time. The main purpose of this
;; package is to make this easier. There are however also some helper
;; functions for manipulating paths on w32.
;;
;; To choose shell customize group the `w32shell'.
;;
;; To run interactive shells you can use `cygwin-shell', `msys-shell'
;; and `cmd-shell'.
;;
;; Notice that you can get the paths to cygwin and MSYS automatically
;; if you use EmacsW32. From the menu bar choose Options - Customize
;; EmacsW32... and then let Emacs search for those paths.
;;
;; Put this in your .emacs:
;;
;; (require 'w32shell)
;;
;;
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;;
;;; Change log:

;; 2005-12-15 More careful check of shell exec.
;; 2005-12-21 (w32shell-delayed-customize): No dialog box.
;; 2005-12-22 (w32shell-set-shell): Call cygwin-mount-activate later.
;; 2006-12-13 Added support for gnuwin32 progs that comes with EmacsW32
