Hey Guix,
Org-mode seems to still have some byte compilation issues when used as a dependency for other packages. The specific symptom is extremely similar to the one reported and fixed at [http://issues.guix.info/issue/38479]. To reproduce: 1) Install emacs-org-jira in your profile, and set it up (lots of annoying steps with API tokens, authinfo etc etc) 2) Run `M-x org-jira-get-boards': --8<---------------cut here---------------start------------->8--- org-jira--render-board: Symbol’s function definition is void: org-outline-overlay-data --8<---------------cut here---------------end--------------->8--- To see the issue without reproducing it (using bash): --8<---------------cut here---------------start------------->8--- $ grep -rni 'org-outline-overlay-data' $(guix build emacs-org-jira) --8<---------------cut here---------------end--------------->8--- This gives: --8<---------------cut here---------------start------------->8--- Binary file org-jira.elc matches --8<---------------cut here---------------end--------------->8--- Byte-compiling the org-jira.el file manually gives an .elc file without a reference to `org-outline-overlay-data'. This leads me to believe that the previously posted fix for #38479 could be extended to make sure Emacs' built-in packages are at the trailing end of EMACSLOADPATH, so after any other packages.
