>Did you run ./autogen.sh before ./configure?

I did, yes, I attached the output in case you're interested. It seems

like it starts failing after the following line:

checking for install-info... /usr/bin/install-info

The problem is I end up with an empty Makefile, so make fails

afterwards.

I think what was missing were the following lines from the

AUCTeX-documentation:

(load "auctex.el" nil t t)

(load "preview-latex.el" nil t t)

When I added those, it worked. I guess these lines are not necessary

when installing via ELPA?

I think I've changed this based off of this post:

https://emacs.stackexchange.com/questions/41321/when-to-specify-a-package-name-in-use-packages-ensure-tag/41324#41324

I wanted to load LaTeX-mode, not TeX-mode, which is in latex.el. I also

load reftex using the following snippet:

(use-package reftex-mode

  :ensure auctex

  :hook LaTeX-mode)

Anyway, the patch was still working with the properly installed auctex.
