Org Mode is borked

Hi Guix,

Our Org Mode package (emacs-org) seems to be broken in a funny way.

Here's how to reproduce this bug (on commit dac7928):

1) Install ‘emacs’ and ‘emacs-org’.

2) Start Emacs and work around https://debbugs.gnu.org/38399by adding

the directory containing org to the front of ‘load-path’:

--8<---------------cut here---------------start------------->8---

(push "/path/to/org-9.2.6" load-path)

--8<---------------cut here---------------end--------------->8---

3) Open a new org file:

--8<---------------cut here---------------start------------->8---

C-x C-f foo.org RET

--8<---------------cut here---------------end--------------->8---

4) Enter the following text into the buffer:

--8<---------------cut here---------------start------------->8---

#+STARTUP: indent

--8<---------------cut here---------------end--------------->8---

5) Verify you're running Org Mode version 9.2.6 by running:

--8<---------------cut here---------------start------------->8---

M-x org-version RET

--8<---------------cut here---------------end--------------->8---

6) Here comes the fun part: Hit C-c C-c. This will produce the

following error message:

--8<---------------cut here---------------start------------->8---

Symbol’s function definition is void: org-outline-overlay-data

--8<---------------cut here---------------end--------------->8---

7) Now reload Org from source (instead of the .elc files):

--8<---------------cut here---------------start------------->8---

C-u C-c C-x !

--8<---------------cut here---------------end--------------->8---

6) Repeat step 6. This time it succeeds!

--8<---------------cut here---------------start------------->8---

Local setup has been refreshed

--8<---------------cut here---------------end--------------->8---

The function ‘org-outline-overlay-data’ isn't defined anywhere in the

org-9.2.6 source, but it is defined in the org bundled with Emacs.

Because of this I suspect that the new emacs-build-system generates a

weird chimera containing parts of both org-9.2.6 and org-9.1.9.

To my untrained eye this looks like it’s probably a consequence of the

aforementioned bug #38399. So I'd expect this issue to disappear as

soon as that one is fixed.

Regards,

Diego

Hello Diego!

I could reproduce (and fix :-)) this problem.

The solution was to *prepend* instead of appending the source directory of the software being

compiled to EMACSLOADPATH, in the 'add-source-to-load-path phase of the

Emacs build system.

Pushed to master with commit add773c37a10e2c900fcfaff745e095b7fe96fbb.

Thank you for the report and reproduction steps.
