Failing to load, showing this 'Symbol's function definition is void: defvar-1'

Failing to load, showing this 'Symbol's function definition is void: defvar-1'

[Sharon Kimble]

I unfortunately upgraded this morning to emacs-30.0.50, and since then I can't get into my usual emacs of 29.0.50. 

When I'm loading emacs-29.0.50 from /usr/local/bin/ it is consistently failing to load saying "Symbol's function definition is void: defvar-1".

My init.el is this -
====
;;; init.el --- sharon's config -*- eval: (read-only-mode 1) -*-
;; Make sure that Git version of Org mode is being loaded instead of the built-in version.
(add-to-list 'load-path (expand-file-name "/home/boudiccas/.emacs.d/elpa/org-9.5.5"))
;;;(add-to-list 'load-path (expand-file-name "/home/boudiccas/.emacs.d/elpa/org-9.6"))
(add-to-list 'load-path (expand-file-name "/home/boudiccas/git/org-contrib/lisp"))

(require 'package)
(setq package-enable-at-startup nil)
(package-initialize)


(require 'ob-tangle)
(org-babel-load-file "/home/boudiccas/.emacs.d/config22-2.org")
====

It seems to be baulking at the last 2 lines, can somebody help please?

Thanks
   Sharon.

Emacs 30.0.50 is the bleeding edge of the development tree. It will be
unstable by definition. The error you are getting looks like an internal
Emacs error unrelated to org mode.

I would wait a day or so and pull new sources and re-build to see if the
issue is fixed. If not, log a bug report.

If a working Emacs is critical to your activities, I would revert back
to 28.2 or maybe 29, which is in pre-release state, so a little more
stable than the bleeding edge dev code. Note that there is an Emacs 29
branch, so you can checkout emacs-29 to get the most recent release
candidate for Emacs 29.

In general, org mode won't attempt to fix issues introduced in the HEAD
soruces of Emacs as these sources tend to be in flux and issues will
often be resolved by other non-org specific changes. Issues at this
level tend to be a 'wait and see'.

Thanks for replying Tim, and as you can see I'm back in emacs.

I know that building emacs isn't part of org-modes mailing list setup, but it looked like '(require 'ob-tangle)' was causing the problem, hence I asked the org-mode mailing list.
  
For the benefit of the archives these are the steps I took -
  
  ====
make clean
make distclean
sudo make clean
sudo make distclean
delete /home/foo/git/emacs
git clone -b master git://git.sv.gnu.org/emacs.git    
cd git/emacs
git checkout origin
git checkout emacs-29
/autogen.sh
configure
make
src/emacs -Q ;;; if this works, then try loading emacs, and if that works, then bobs your uncle!
sudo make install
  ====

This is because I'd got a failed build and install, so it all needed clearing out before I could delete the failed emacs git download, so it needed a fresh download.

Anyway, I've learnt from my mistake and have documented it all just in case I do it again.

Thanks    
  Sharon.
