magit fails to locate emacsclient at /usr/local/bin/emacsclient

[zenny]

Hi,

I compiled emacs 26.2 in ubuntu (still in 14.04) to use with doom-emacs and it reports that it cannot locate emacsclient

Warning (with-editor): Cannot determine a suitable Emacsclient

Determining an Emacsclient executable suitable for the
current Emacs instance failed.  For more information
please see https://github.com/magit/magit/wiki/Emacsclient.
Warning (ox-pandoc): Pandoc version number can not be retrieved.

in spite of

$ which emacsclient
/usr/local/bin/emacsclient

$ emacsclient -v
emacsclient 26.2

I could not locate any reason why magit failed to locate the emacsclient which was installed on the default location. Any clues?

Cheers,

Did you do that and also follow the links at the bottom of that page?

@tarsius, /usr/local/bin where the emacsclient is located is defined in my $PATH as evident from:

$ echo $PATH
/home/zenny/.asdf/shims:/home/zenny/.asdf/bin:/home/zenny/.local/share/umake/bin:/home/zenny/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/usr/brlcad/bin:/usr/lib/jvm/java-8-oracle/bin:/usr/lib/jvm/java-8-oracle/db/bin:/usr/lib/jvm/java-8-oracle/jre/bin:/home/zenny/.fzf/bin

Fyi, the emacs is also in v26.2 as explained in 2 at the bottom of the link you sent.

Anything else that I missed to do? If so, what could be that?

The emacsclient binary is where it should be:

$ which emacsclient 
/usr/local/bin/emacsclient

Thanks.

[tarsius]

    /usr/local/bin (t)
      /usr/local/bin/emacsclient (nil)

Instead of nil this should show the version. That's weird--above you showed how you got the version of that. Do it very explicitly: /usr/local/bin/emacsclient --version.

[zenny]

$ /usr/local/bin/emacsclient --version
emacsclient 26.2

Even tried with explicitly appending

(add-to-list 'exec-path "/usr/local/bin")

to $HOME/.emacs.d/init.el ('bin/doom refresh' was also executed afterwards), but with the same message.

[tarsius]

This is how the version is determined:

(defun with-editor-emacsclient-version (exec)
  (let ((default-directory (file-name-directory exec)))
    (ignore-errors
      (cadr (split-string (car (process-lines exec "--version")))))))

(with-editor-emacsclient-version "/usr/local/bin/emacsclient")

In your case that apparently returns nil. Change the definition until you know what is going wrong. Start by removing the ignore-errors.
