Can't Get Org-Drill to Work

Can't Get Org-Drill to Work

[M. P.]

I am trying to install org-drip. I have org and org-contrib installed through Elpa. The Problem has something to do with the line (require `org-drill. When I try to run this config I get

Warning (initialization): An error occurred while loading ‘/Users/m.r.p/.emacs’:

Symbol's function definition is void: copy-list

The documentation tells me to You will also need to make sure that Org's "contrib/lisp" directory is in the emacs load-path. How do I do this? 


                             Here is my config file.
;; Added by Package.el.  This must come before configurations of
;; installed packages.  Don't delete this line.  If you don't want it,
;; just comment it out by adding a semicolon to the start of the line.
;; You may delete these explanatory comments.
(package-initialize)
(require 'org-drill)
(require 'package)
(add-to-list 'package-archives '("org" . "http://orgmode.org/elpa/") t)

Any Ideas would be most appreciated.

From a quick look, this appears to be a bug in `org-drill', but luckily
it's easy to work around in your config.

To do so, add (require 'cl) to your config, before (require 'org-drill).

The problem is that `copy-list' is a function defined in `cl' (as an
alias to `cl-copy-list' in `cl-lib'), but `org-drill' only requires `cl'
at compilation time. `org-drill' should use `cl-copy-list' instead, or
else require `cl' unconditionally (i.e., without `eval-when-compile').

I don't think you'll need to do this, ELPA will have handled it.

Hope that helps

What is your emacs version?

Not that that could be causing the issue you are seeing, but there is no
point installing both org and org-plus-contrib. org-plus-contrib is a
super-set of org.

copy-list is in the cl-lib library. So the order of your package
initialization is probably the issue.

You do not need to do anything like that if you are installing
org-plus-contrib. org-plus-contrib includes files from Org and contrib/
directories under one single flat directory hierarchy.

You need to update the load-path as suggested if you are cloning the Org
repo and *not* building Org as it's supposed to (by customizing the local.mk
).

I would rearrange the above as:

(require 'package) ;You need this require so that the `package-archives'
var is declared
(add-to-list 'package-archives '("org" . "http://orgmode.org/elpa/")
:append)
(package-initialize)               ;MANDATORY (before you require *any*
package)
;; Now do all the package requires as needed (I would rather let the
packages be
;; auto-loaded instead.)
(require 'org-drill) ;Assumes that you have already installed
`org-plus-contrib' first

You can step through the above in an emacs -Q session as follows (tested on
emacs 25.2):

1. Start emacs -Q
2. Evaluate the below:

(progn
  (require 'package) ;You need this require so that the `package-archives'
var is declared
  (add-to-list 'package-archives '("org" . "http://orgmode.org/elpa/")
:append)
  (package-initialize)
  (package-refresh-contents)
  (package-install 'org-plus-contrib)
  (require 'org-drill))

Then when I do M-: (featurep 'org-drill), I get "t" in the echo area. That
means that that package got loaded fine.
