	      Building and Installing Emacs from Bazaar

If this is the first time you go through it, you'll need to configure
before bootstrapping:

  $ ./configure

Some of the files that are included in the Emacs tarball, such as
byte-compiled Lisp files, are not stored in Bazaar.  Therefore, to
build from Bazaar you must run "make bootstrap" instead of just "make":

  $ bzr pull
  $ make bootstrap

Normally, it is not necessary to use "make bootstrap" after every
update from Bazaar.  "make" should work in 90% of the cases and be
much quicker.

  $ make

(If you want to install the Emacs binary, type "make install" instead
of "make" in the last command.)

Occasionally the file "lisp/loaddefs.el" (and similar automatically
generated files, such as esh-groups.el, and *-loaddefs.el in some
subdirectories of lisp/, e.g. mh-e/ and calendar/) will need to be
updated to reflect new autoloaded functions.  If you see errors (rather
than warnings) about undefined lisp functions during compilation, that
may be the reason.  Another symptom may be an error saying that
"loaddefs.el" could not be found; this is due to a change in the way
loaddefs.el was handled in version control, and should only happen
once, for users that are updating old sources.  Finally, sometimes
there can be build failures related to *loaddefs.el (e.g. "required
feature `esh-groups' was not provided").  In that case, follow the
instructions below.

To update loaddefs.el (and similar files), do:

  $ cd lisp
  $ make autoloads

If either of the above partial procedures fails, try "make bootstrap".
If CPU time is not an issue, the most thorough way to rebuild, and
avoid any spurious problems, is always to use this method.

Users of non-Posix systems (MS-Windows etc.) should run the
platform-specific configuration scripts (nt/configure.bat, config.bat,
etc.) before "make bootstrap" or "make"; the rest of the procedure is
applicable to those systems as well.

Questions, requests, and bug reports about the Bazaar versions of Emacs
should be sent to emacs-pretest-bug@gnu.org rather than gnu.emacs.help
or gnu.emacs.bug.  Ideally, use M-x report-emacs-bug RET which will
send it to the proper place.

Because the Bazaar version of Emacs is a work in progress, it will
sometimes fail to build.  Please wait a day or so (and check the bug
and development mailing list archives) before reporting such problems.
In most cases, the problem is known about and is just waiting for
someone to fix it.


Note on accessing the Bazaar repository
---------------------------------------

Write access to the Bazaar repository is currently done via Bazaar's
sftp:// protocol; see http://www.emacswiki.org/emacs/BzrForEmacsDevs.
We plan to offer bzr+ssh:// access later.  More discussion about that
is at https://savannah.gnu.org/support/?107077.
