bug#34323: reproducibility: absolute file names in ox-odt.elc

[Glenn Morris]

Package: emacs,org-mode
Version: 26.1.91
Severity: minor

The compiled file ox-odt.elc contains strings that refer to the
absolute location of the build directory, through
org-odt-schema-dir-list and org-odt-styles-dir-list.
For example, in the Emacs 26.1.91 pretest tarfile, it contains
"/home/nico/work/emacs-26/etc/schema/" and
"/home/nico/work/emacs-26/etc/styles/".
This means the generated elc file is non-reproducible (ie, the contents
change depending on the build directory).

(Like https://debbugs.gnu.org/34321, issued spotted in
https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/diffoscope-results/emacs.html

I'm Cc'ing the author of ox-odt.el as he might have more insight.

It's due to the eval-when-compile sections in org-odt-schema-dir-list
and org-odt-styles-dir-list. These don't make sense to me. All they do
is add the build directory. There is a comment "see make install", but I
cannot see what this refers to. No similar variable initializes itself
in this way AFAIK. If those sections are removed, does anything stop
working?

I don't know. I removed `the `eval-when-compile' calls. We'll see what
horrible things happen.

I'm closing this bug for now. Thank you for reporting it.
