Searching for program: no such file or directory, diff

Searching for program: no such file or directory, diff

[pp]

hi all,
I installed emacs under WindowsXp half a year ago, and it worked well.
However, When I use ediff command to compare two buffer, it doesnot
work and says "Searching for program: no such file or directory, diff"
Then I tried to install diff or ediff, but it seems not a right way to
fix the problem.
So, What should i do if I wanna use ediff command on WindowsXp?

              -by cp

Perhaps `M-x customize-option ediff-diff-program'.

[Note: I didn't bother to check the code, so this is a guess. I just did `C-h o
ediff M-SPC -diff' in Icicles to show me all user options with substrings
`ediff' and `-diff'. The help text for this option suggests it might help. `C-h
o' is defined in library help-fns+.el.

I use Cygwin, so the option value I use is just "diff". But you might need some
other value - perhaps an absolute file name. The value should point to the
`diff' program that you have on your machine. If the program is in your path,
then the name can be relative.

Hi,

I found your mails while searching the same issue in google, my problem is now solved.

Just inform you that there is a more easy way to do this.

Install kdiff3 for windows and put its bin path to PATH variable, and restart emacs, than it's done :D .
