Re: Emacs fails to bootstrap, gnus / mh-e related

Miles,

Sorry for the long hiatus, but work (kepler.nasa.gov) has been keeping
me way busy.

Yes, as Andreas said, it should contain all of the autoloads.

Look for mh-autoloads in lisp/Makefile to see how it should be
created. In particular, the missing bits are created with the
following command:

        $(EMACS) $(EMACSOPT) \
           -l autoload \
           --eval "(setq generate-autoload-cookie \";;;###mh-autoload\")" \
           --eval "(setq generated-autoload-file 
\"$(lisp)/mh-e/mh-loaddefs.el\")" \
           --eval "(setq make-backup-files nil)" \
           -f batch-update-autoloads $(lisp)/mh-e

I pretty much copied the command that builds loaddefs.el.

The mh-autoloads depends on $(lisp)/mh-e/mh-loaddefs.el, so if that
file existed, it wouldn't be rebuilt. If you remove it, and run "make
mh-autoloads" in the lisp directory, you should be set.

I just did an update after eons, and a make bootstrap (after a make
maintainer-clean) and the build proceeded without error.

Note that as you observed, we haven't touched MH-E (except for a few
minor bug fixes) since Emacs was frozen, nearly a year ago. I guess the
Makefiles aren't conducive to parallelism.
