I started the emacs server with:

$ emacs --daemon

I started gforth and tried to locate locate:

$ gforth
Gforth 0.7.9_20160616, Copyright (C) 1995-2015 Free Software Foundation, Inc.
Gforth comes with ABSOLUTELY NO WARRANTY; for details type `license'
Type `bye' to exit
locate locate *ERROR*: Symbol's function definition is void: forth-find-tag
ok

Gforth experts - where do I go from here? I've been searching on the error message but find the answers to be too confusing to follow.

Thanks in advance!

That's an emacs error message, and it means that you have not loaded
gforth.elc (or gforth.el).

Does not work for me. Must I do this:
emacs --daemon
gforth gforth.el
or
emacs --daemon gforth.el
gforth
or
something else?

No difference with cygwin or native linux.

The usual way is to described in

https://www.complang.tuwien.ac.at/forth/gforth/Docs-html/Installing-gforth_002eel.html#Installing-gforth_002eel

It would be better to have the Gforth installer include this stuff in
the site-lisp directory or something. When I last looked (many years
ago), there was no reliable way to do this, so I didn't. Maybe there
is in the meantime. Or we approach the Emacs people to include at
least the first four commands.

Guys, this worked for me...

(setq load-path (cons "~/src/gforth-0.7.9_20160616" load-path))
(load "gforth")

1. I use Mint Linux 17.3.

2. Downloaded and built emacs 24.5 using "./configure --with-x-toolkit=lucid".

3. I started an instance of emacs and ran "M-x server-start".

4. When I ran gforth in a xterm, I typed "locate locate".

5. The Emacs instance reacted by asking me where the TAGS file is.

6. I replied with "~/src/gforth-0.7.9_20160616/", and up popped the source for the locate word.

(Thanks again, Anton.)

Ooops ... #6 should be...

6. I replied with "~/src/gforth-0.7.9_20160616/TAGS", and up popped the source for the locate word.

(I left the TAGS off of the previous message.)
