[Matlab-emacs-discuss] problems with the actual (and earlier Makefiles) for emacs 29.2

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

Hi

I am currently running Emacs 29.2 and I had problems with 
commit a78b368387c8
because of 
autoload-insert-section-header

More precisely 
--8<---------------cut here---------------start------------->8---
Debugger entered--Lisp error: (error "cedet-matlab.el:0:0: error: void-function: (autolo...")
  signal(error ("cedet-matlab.el:0:0: error: void-function: (autolo..."))
  error("%s:0:0: error: %s: %s" "cedet-matlab.el" void-function (autoload-insert-section-header))
  autoload-generate-file-autoloads("cedet-matlab.el" nil "/home/oub/ALLES/emacs/site-lisp/packages/src/Matla...")
  make-directory-autoloads(("/home/oub/ALLES/emacs/site-lisp/packages/src/Matla...") "/home/oub/ALLES/emacs/site-lisp/packages/src/Matla...")
  batch-update-autoloads()
  command-line-1(("--eval" "(setq debug-on-error t)" "-L" "./" "--eval" "(setq generated-autoload-file \"/home/oub/ALLES/ema..." "-f" "batch-update-autoloads" "/home/oub/ALLES/emacs/site-lisp/packages/src/Matla..."))
  command-line()
  normal-top-level()

make: *** [Makefile:34: autoloads] Error 255
--8<---------------cut here---------------end--------------->8---

Another  problem was (void-function batch-update-autoloads) that
function is now obsolete, that problem needs to be addressed since we
want to cater for various Emacs version

So it was suggested to me by Arash Esbati
to have a look at the Auctex makefile, which looks like

AUTOLOAD=--eval '\
(let* ((autoload-file (expand-file-name "$@")) \
       (autoload-file-dir (file-name-directory autoload-file))) \
  (if (fboundp (quote loaddefs-generate)) \
      (loaddefs-generate autoload-file-dir autoload-file) \
    (setq generated-autoload-file autoload-file) \
    (update-directory-autoloads autoload-file-dir)) \
  (save-buffers-kill-emacs t)'

auctex-autoloads.el:
        $(EMACS) $(AUTOLOAD)

However, I realized that recently the Makefile was changed quite a bit
(and I don't hope this will cause problems with ELPA since now, it seems
that the makefile run tests with matlab itself, and it is not clear to
me what happens if matlab is not installed on a machine that just want
to generate a ELPA package)

So in the new Makefile the autoloads part is gone, but I am running into
a different sort of problem with 29.2
--8<---------------cut here---------------start------------->8---

--8<---------------cut here---------------end--------------->8---

In the first run but in the second run, after make clean, I obtain the
old:

But at least with 28.2 I  can compile commit 
a78b368387c8!

So we here at least 2 problems that need to be addressed.

@John introduced these changes, what do you say?
I was trying to modify the Makefile in commit a78b368387c8
following Arash advice, till I realized, that this is not the last
commit! 😳.

The reason was, that  I was in my local repository that
corresponds to Sourceforge, till I realized that changes you made.

So I think we need to address the latest commit. John?
