find-dired does not work on emacs24 + win + mingw

Hi,

My env. is Window 7 64bit + MinGW.
I find that find-dired of emacs24 does not work on this env. (I got emacs24
from http://alpha.gnu.org/gnu/**emacs/windows/<http://alpha.gnu.org/gnu/emacs/windows/>
)

The output of find-dired is like below:

*  c:/emacs/lisp/:*
*  find . "(" -name "*find-dired*" ")" -ls*
*  227084    7 -rw-r--r--   1 sthfrnth Administrators    12792 Jan  19:38
find-dired.el*
*  956351    6 -rw-r--r--   1 sthfrnth Administrators    11411 Jan  05:35
find-dired.el.ok*
*  227085    5 -rw-r--r--   1 sthfrnth Administrators     8669 Jan  19:38
find-dired.elc*
*  3731074    4 -rw-r--r--   1 sthfrnth Administrators     7530 Jan  13:35
find-dired.elc.ok*
*  *
*  find finished at Fri Jan 27 13:09:23*

When enter pressed on file line, it prompted "Unrecognized line!  Check
directory-listing-before-filename-regexp".

I replaced find-dired.el with emacs23's version, it works ok. The output is
like below:

*  c:/emacs/lisp/:*
*  find . "(" -name "*find-dired*" ")" -exec ls -ld "{}" ";"*
*  -rw-r--r--   1 sthfrnth Administrators    11411 Jan 11 05:35
find-dired.el*
*  -rw-r--r--   1 sthfrnth Administrators    12792 Jan 16 19:38
find-dired.el.bak*
*  -rw-r--r--   1 sthfrnth Administrators     7530 Jan 22 13:35
find-dired.elc*
*  -rw-r--r--   1 sthfrnth Administrators     8669 Jan 16 19:38
find-dired.elc.bak*
*  *
*  find finished at Fri Jan 27 13:17:44*

I think the output of "*find . "(" -name "*find-dired*" ")" -ls*" is not
matching some parsing functions in find-dired.el.
I tried to modify it but did not succeed.

Can anyone fix this?

And where did you get the port of GNU Find?

This output is wrong: it doesn't show the date after the month, only
the hour.  "Jan  13:35" etc. is not a valid date-time format.

With the port of GNU Findutils I have, I don't see that problem.

With my find.exe, this error doesn't happen.  I'm quite sure you see
the error message because of the invalid date format.

As you see, Emacs 23 instructed find.exe to invoke ls, instead of
using the built-in -ls option.  Your ls.exe produces valid date
format, so the command works.

See above: you need to "fix" your Findutils.  E.g., try this port:

  http://sourceforge.net/projects/ezwinports/files/findutils-4.2.30-w32-bin.zip/download

Hi Eli,

You are right. It is because the invalid date format in the output of my
find with -ls option. My find comes from MinGW msys 1.0.

I tried the port you suggested. It works, but not quite convenient. It can
not run in this way: "find . -name *foo*".

The find port in this package works better for me:
http://unxutils.sourceforge.net/

Thank you very much.

What do you mean "can not run"?  You need to quote the *foo* part, but
otherwise it works for me.  If you quote it, what do you see?

The "find.exe" in this package
http://sourceforge.net/projects/ezwinports/files/findutils-4.2.30-w32-bin.zip/download

produces:
*
*
*C:\emacs\lisp>find . -name *find**
*find: paths must precede expression*
*Usage: find [-H] [-L] [-P] [path...] [expression]*
*
*
*C:\emacs\lisp>find . -name "*find*"*
*find: paths must precede expression*
*Usage: find [-H] [-L] [-P] [path...] [expression]*

whether or not name quoted.

The "find.exe" in this package
http://unxutils.sourceforge.net/
produces:

C:\emacs\lisp>find . -name *find*
.\cedet\semantic\db-find.el
.\cedet\semantic\db-find.elc
.\cedet\semantic\find.el
.\cedet\semantic\find.elc
.\cedet\srecode\find.el
...
C:\emacs\lisp>find . -name "*find*"
.\cedet\semantic\db-find.el
.\cedet\semantic\db-find.elc
.\cedet\semantic\find.el
.\cedet\semantic\find.elc
.\cedet\srecode\find.el
...

I don't know why.
I think the second "find.exe" is more powerful in my env..
