Building Emacs

Building Emacs

[Nick Roberts]

In the past I would use "make recompile" in the lisp directory followed by
"make" in the emacs directory because it was much faster than doing a
bootstrap, and because I have my own experimental versions of files in the lisp
directory that I don't want autoloading.

Now I'm not sure what "make" does.  It outputs "nil" so many times that any
meaningful message flashes by and it insists on generating autoloads for all
files in the lisp directory.

Is there a way to get the old behaviour.  It left problems from time to time
but I could generally see how to fix them.

It does pretty much what you did.

I don't see that.  Could you post some example session?

That was also the case in the past, except that your recipe simply never
updated the loaddefs.el file.

How 'bout adding "no-autoloads" annotations to the files you don't
want autoloaded?

I think maybe Nick applied an early version of the window-group patch,
which contains some debug statements I forgot.

Could you try removing those, Nick?

Yes, you're right.  Thanks.  However, it doesn't explain why it tries to
bootstrap when I just do make:

   nickrob@kahikatea:~/emacs/build$ make
   boot=bootstrap-emacs;                         \
   ...

I don't recall this happening before.  I had presumed that this is due to this
change:

2008-06-22  Stefan Monnier  <monnier@iro.umontreal.ca>

	* Makefile.in (${lisp} ${SOME_MACHINE_LISP}, ../lisp/loaddefs.el):
	Use $(BOOTSTRAPEMACS) rather than witness-emacs.

Maybe it has something to do with using a separate build directory
(~/emacs/build/) to the source (~/emacs/src)

I'm not sure what you're saying but I'm saying the behaviour appears to have
changed.

I could do but it's more inconvenient than my previous method.

It could very well be: I never used a separate build directory, so
I don't know what goes where and what can be assumed to be where, so
whenever I touch the Makefiles, I tend to introduce problems in
this area.
The fact that the Makefiles seem to contain somewhere around 0 bytes of
comments about this doesn't help, of course.

No doubt, it has changed.

What can i say: the Makefile is designed to build Emacs, not some local
derivative.  This said, I have my own local derivative with about
1MB's worth of changes, and I never needed to silence autoloads, so
I find your situation rather odd.  Of course, you can also hack your
local derivative to use different Makefile rules ;-)

Building Emacs

Hi,

I've just cloned Emacs from git ant tried to build Emacs on GNU Linux
(Debian 9), but the configure script is missing.

So, I tried to generate via autoconf, but I got the following error:

configure.ac:54: error: possibly undefined macro: AS_ECHO
      If this token and others are legitimate, please use m4_pattern_allow.
      See the Autoconf documentation.
configure.ac:1695: error: possibly undefined macro: m4_default

Am I missing something?

Have you tried ./configure ?

Try ./autogen.sh instead, as described in INSTALL.REPO.

As I said there is no configure script.

Ok, using ./autogen.sh the ./configure was generated, I didn't notice
INSTALL.REPO, only the INSTALL.

BTW, sorry my ignorance, but why are there 2 files about installation?

Thanks

Sorry for that, I misunderstood your original message.

The first one looks like it talks about installing from the git repo, the other one probably from a source package in your distribution ?

But it's confusing and they probably should be merged.

INSTALL is for installation from a release tarball (which includes
./configure pre-generated), INSTALL.REPO has extra info about
installation from the git repository.

One is for install from a release (e.g. 26.3), and the other is for
install from git repo.   There are different instructions, such as `make
bootstrap' when building from the git repo.

The first paragraph of INSTALL says, "For information about building from a 
repository checkout (rather than a release), also read the file INSTALL.REPO."

Indeed.

From time to time, I always download Emacs sources and build Emacs from
scratch, so I  followed a script that was based on INSTALL file from some
years ago when INSTALL.REPO didn't exist.

It crashes when started:

$ emacs

But do not crash when:

$ emacs -q
M-x load-file
~/.emacs

Please run that under a debugger, produce a backtrace when it crashes,
and use report-emacs-bug to report the details.

Thanks.
