Building the current emacs-24 branch fails for me.

[Message part 1 (text/plain, inline)]

I cannot reproduce the problem; the same checkout (emacs-24 bzr 117169) 
works for me with that recipe on my host (Fedora 20 x86-64, GCC 4.9.0). 
 See attached build transcript and config.log.

Looking at your build snippet I'm suspicious of lines like this:

Loading emacs-lisp/byte-run (compiled; note, source file is newer)...

At this point during the bootstrap process there shouldn't be a compiled 
file byte-run.elc, because it hasn't been built yet.  In my log I see:

Loading emacs-lisp/byte-run (source)...

which is what I'd expect.  Perhaps you were doing a 'make -j' and ran 
into a parallelization problem?  Or maybe you did two 'make's, one 
interrupted?  Neither should cause this problem, but still, we need an 
explanation for why byte-run.elc was present when it should have been 
absent.

This doesn't seem to be a clean tree:

Did you switch to the emacs-24 branch in the same git repository, and
then typed the command above?  If so, either "make bootstrap" or clone
a separate repository, switch to emacs-24 there, and then your
commands should work.

In Emacs development, the trunk and the release branch diverge very
quickly, so "make clean" is not enough to give you a "clean tree".

The main point is that `make clean' does not delete the compiled lisp
files (and cannot, since they are prebuilt in lisp tarfiles).
`make maintainer-clean', or `make bootstrap' does.
Always use `make bootstrap' if CPU time is not a factor, even when
building the same branch.

(Presumably this issue is going to occur more in the git-era, since it
doesn't have shared repos.)

Indeed, this was a simple user error. Sorry for the noise.

I did a git reset --hard and make distclean, but not a make bootstrap.
git st told me the repo was clean, but that obviously does not check
files in .gitignore. I should have used git clean. Meh.

Thanks for the quick response.

This make me think, should this from src/Makefile.in:

  $(RUN_TEMACS) --batch --load loadup bootstrap || exit 1; \

use (setq load-suffixes '(".el"))
to try and avoid this kind of problem?

Wouldn't load-prefer-newer be a better choice?

I guess it wouldn't do any harm to have a bootstrap-emacs that was
formed from a mix of compiled and uncompiled files...

The easiest (and IMO sanest) way to do this is to make load-prefer-newer
non-nil by default.
Fancy opening that can of worms...?

Try it on trunk?
