Hello, Emacs.

I've just updated a master repo here, and tried a make bootstrap.

I get the error message:

    cedet/semantic/bovine/c.el:35:1: Error: Loading file
    /home/acm/emacs/emacs.git/sub-master-a/lisp/cedet/semantic/bovine/c-by.elc
    failed to provide feature `semantic/bovine/c-by'

.  There is a perfectly good line at the end of this file:

    (provide 'c-by)

.  So what is expecting the compound symbol `semantic/bovine/c-by' to be
provided, and why?

I tried a "make bootstrap" on the current trunk now (on
Debian/bullseye), and I did not get that error message...

Thanks for looking at it.

I got the error message again this morning (it wasn't just a bad dream),
and I'm trying to think how it could have happened.

The way of calling require

    (require 'semantic/bovine/c-by)

with the path included in the required symbol is totally new to me.  It
just seems like a wrong thing to do.  But it's been working for many
years, obviously, for some value of "working".

I do a git status, and notice amongs my untracked files list:

        lisp/cedet/semantic/wisent/java-tags-wy.el
	lisp/cedet/srecode/srecode-template-wy.el

, so I've deleted these.  It hasn't helped.

I've inserted a

    (provide 'semantic/bovine/c-by)

into c-by.el.  Now I get other errors:

.  The word SEMICOLON doesn't appear anywhere in the git log.  I really
don't want to start burrowing through the internals of the cedet things.

I don't understand how Emacs is building for everybody else but not me.
I've tried reconfiguring my Emacs with no options to ./configure.  This
hasn't helped either.

Perhaps this conversation would be better on emacs-devel.  Anyhow thanks
for your patience in reading this miserable post!

I'd suggest pulling down a clean Emacs tree to see whether the problem
is present there, too...  or perhaps use a "make extraclean" (I think
that's the target that'll remove everything, even more than "bootstrap")
and see whether that helps.

I tried the extraclean first.  It worked!  Phew!

There must have been something hanging over from cedet in files not
removed by bootstrap.  I hadn't actually used the repo for, perhaps, a
year.  I'll remember the recipe.

Have a good Saturday!

Whoops, forgot about the actual bug.  It feels like there was an actual
bug in make bootstrap here, but it's not obvious what.

Clearly the bug needs to be closed.  What do you think it is?  a
notabug, a wontfix, or what?

It is somewhat surprising that "make bootstrap" removes less stuff than
"extraclean", I think?  People understandably get a bit confused about
all these "clean" levels, but I'm not sure what to do about it...

Just a "close" with no other status, I think.  :-)

OK.  This post is closing the bug.

Thanks again for the help.
