org-export-get-reference: Symbol's function definition is void (fixed by commenting out)

[dctoedt]

When I installed org-reveal and tried it, the export process threw an error: "Symbol’s function definition is void: org-export-get-reference"

I searched for that function in ox-reveal.el and found it at line 381 --- commenting out that line seemed to solve the problem.

(preferred-id (or (org-element-property :CUSTOM_ID headline)
;; (org-export-get-reference headline info) ;; I COMMENTED OUT THIS LINE
(org-element-property :ID headline)))

I'll leave it to others more skilled than I to determine whether this is truly a fix or just dumb luck.

I had the same problem and updating org-mode solved it. I know have version 8.3.2 and it works well.

Yes, please update Org-mode to 8.3.

I'm using org-version 8.3.5(Emacs version 25.0.95.1) Still have this problem.

Thank you for me Org-mode 9.0 fixed the issue on my Windows and Linux maschines.

(And i am on org-mode 9.0.3 / elpa)

Now I have the same issue on my Macbook Pro. Trying to solve it with installing the latest version of org-mode (9.0.5-elpa org-20170210) from elpa at the end I get an error:
Symbol’s function definition is void: org-link-set-parameters
Even though I tried the org-reload , uninstall, install loop several times, as described here:

Any hints welcome.

Dear all, I had the same problem (on mac with emacs 25.1.1 and org-2017-05-15). I guess it is something with org installation:

Important: you need to do this in a session where no .org file has been visited, i.e., where no Org built-in function have been loaded. Otherwise autoload Org functions will mess up the installation.

This steps worked for me:

• delete all packages from ~/.emacs.d/elpa
• start vanilla emacs (i.e., like with empty init.el and do NOT call package-initialize)
• add org-mode packages archiveM-: (add-to-list 'package-archives '("org" . "http://orgmode.org/elpa/") t)
• call M-x package-list-packages
• install newest org (in my case it was org-2017-05-15)
• restart emacs as usual (all packages will be reinstalled automatically if you require it with use-package)

After this work around the error has gone. But I would still consider it a bug to fix.
