I copied this code from codechef:
But when i press F9 vterm buffer gets activated and the error saying
Usr/bin/time: no such file or directory
Pops up
Help please

(defun er-switch-to-previous-buffer ()
  "Switch to previously open buffer.
Repeated invocations toggle between the two most recently open
buffers."
  (interactive)
  (switch-to-buffer-other-frame (other-buffer (current-buffer) 1)))

(defun runc()
  "Build and runc .cpp files"
  (interactive)
  (if (or (string= major-mode "c++-mode") (boundp 'file))
      (let ((a 10))
        (if (string= major-mode "c++-mode")
            (setq file (buffer-file-name (window-buffer (minibuffer-
selected-window)))))
        (evil-write-all nil)

        (setq code-buf-default-directory default-directory)
        (if (boundp 'buf)
             (pop-to-buffer buf)
          (setq buf (+vterm/toggle nil)))
        (vterm-send-string (concat "cd " code-buf-default-directory ";
") )
        (vterm-send-string (concat "g++ '" file "' -o ~/dDg && echo
'Compiled.'; /usr/bin/time -f \"Executed in %esec. Used %KKB.\" ~/dDg;
rm ~/dDg;") )
        (vterm-send-return)
        (with-current-buffer buf
          (evil-normal-state))
        (er-switch-to-previous-buffer))))

(map! :desc "Run c++ code" "<f9>" #'runc)

Well, is the `time` executable available in `/usr/bin/` on your
system?

----------------------------------------------------------------------

No
When i do
Which usr/bin/time on terminal
It says not found

----------------------------------------------------------------------

Okay, so assuming the executable isn't available at another location,
you either need to install it, or change the ELisp to not call
`/usr/bin/time`.

Yeah
I fixed it by reinstalling the time
sudo apt-get install --reinstall time
And now i run whereis time it clearly shows /usr/bin/time
Thanks
But there is another problem now
when i run the code the vterm shows up the previous error doesn't show
up but a message pops up saying
cmdand quote>
and nothing is shown after this
Help me with this plz

That means there are unbalanced quotes somewhere in the command
string(s) being passed to vterm.

Maybe project-compile will be better solution?

----------------------------------------------------------------------
tanishk56bisht · 2022-06-17 13:42

Yesss
I found that
Now everything is running fine
Thanks
