Re: [BUG] New error: (void-function org-url-p) when exporting to LaTeX [9.4.6 (9.4.6-gc5573b @ /Users/stanton/.emacs.d/straight/build/org/)]

[Tim Cross <theophilusx@gmail.com>]

OK, think I've worked out what the problem is.

The function org-url-p is defined in org 9.5, but not org 9.4. Your
running org 9.4.6, which does not have that function. The fact something
in your install is trying to call org-url-p would indicate you have a
mixed or messed up installation of org (i.e. your setup is loading code
from 2 different versions).

It is very important when upgrading or installing org that no org
functionality is yet loaded to avoid this type of issue. Your best bet
is to remove all org related packages and then try installing org again.
If your using package.el to install org, make sure the call to install
it is early in your init file (before any functionality is loaded which
depends on org). I also find the use-pacakge macro very useful in this
regard as you can also setup things so that no org functionality is
loaded until you try to use something which depends on org. This means
you can typically start Emacs and immediately install/upgrade org
without any issues. Where people tend to come undone is when they have
been running Emacs for a while, have been using org and then to a
package update and the system tries to install a new version of org
(usually only an issue with new major versions rather than patch fix
version updates).
