org-drill doesn't load with spacemacs configuration

Question

I am trying to load org-drill in Emacs with spacemacs configuration.

I have added the module into .spacemacs file as:

(custom-set-variable
 ;; ...
 '(org-modules
   (quote
    (org-bbdb org-bibtex org-docview org-gnus org-info org-irc org-mhe org-rmail org-w3m org-drill)))
  ;; ...
)

Now when I am opening spanish.org (as in instruction), I see an error in *Messages* buffer:

Problems while trying to load feature org-drill

Does anyone know how can I fix this?

Thanks

Answer 1

See this issue https://github.com/syl20bnr/spacemacs/issues/1218.

Basically org-drill.el is not included in the original emacs distribution, so one way you can include the file is to now add org-plus-contrib under dotspacemacs-additional-packages, which will download all org-contrib files, including org-drill.el

This would look as follows :

dotspacemacs-additional-packages '(org-plus-contrib)

Answer 2

I would try with

(custom-set-variable
...
 '(org-modules
   (org-bbdb org-bibtex org-docview org-gnus org-info org-irc org-mhe org-rmail org-w3m org-drill))
...
)

The quote in the '(org....) sounds redundant.
