problem with grep and exec-path

problem with grep and exec-path

[Javier Oviedo]

Hello all:

I am using emacs 21.2 WINXP.

I add the following line to my .emacs file in order to include the execution
path for grep:

;;; Set exec paths.
(setq exec-path (cons "T:/gen/gnu/99-11-01/cygwin-b20/H-i586-cygwin32/bin"
exec-path))
;;;

I evalutate this line and see that indeed the path was modified correctly. I
still get errors when using grep.

If I, however, move grep.exe under the emacs-21.2\bin driectory, everything
seems to work.

Does anyone have any ideas on this path issue? I'd prefer to not have a copy
sitting in emacs-21.2\bin.

Thanks in advance.

Javier.

I never tried exec-path but simply add the binary directories to the
Path environment variable and emacs finds them.

Although this form is probably the simpler and, therefore, more
portable form, I prefer to use:

(add-to-list 'exec-path 
             "T:/gen/gnu/99-11-01/cygwin-b20/H-i586-cygwin32/bin")

Hmmm.  I believe that M-x grep uses essentially the same mechanism as
M-x shell.  Therefore, after setting up exec-path, try M-x shell to
get to a shell buffer and then check the PATH of that shell from the
command line.  Perhaps there is something in your setup that is
resetting the PATH in a new shell.

Another option is to try setting "grep-command" to be the full path of
your grep command.  You may also want to adjust your find-grep-command
variable as well.
