Question on updating to 29.1

Question on updating to 29.1

[PierGianLuca]

Hi everyone!

I have version 28.1 that I "make install"ed on a Ubuntu machine, for the first time. I'd like to update to 29.1 and my question is: do I need to do anything about the old version? it will simply be replaced? I can't find anything about this in the official documentation, say at

https://git.savannah.gnu.org/cgit/emacs.git/tree/INSTALL

Sorry if the question is silly or my terminology is not correct – I'm quite unfamiliar with compilation and versioning.

Cheers,
Luca

Did you install version 28.1 from a Git checkout or from a tarball?  If
you have used Git to fetch the source, you should be able to update to
the most recent version of Emacs using a "git pull" or "git checkout
emacs-29" (or whatever other branch, tag, commit).  If you have
installed it from a tarball, you will need to download a new release.
This link should redirect you to a close-by FTP mirror: 

  http://ftpmirror.gnu.org/emacs/emacs/emacs-29.1.tar.xz

The installation procedure should be similar or even analogous to the
installation for Emacs 28, with the possible exception of additional
./configure flags that you might be interested in, which have been added
in Emacs 29.

Thank you Philip and Basile (who gave me advice off-list).

Sorry for not being clear:

> Did you install version 28.1 from a Git checkout or from a tarball?

Tarball. I first *un*installed the Ubuntu pre-packaged Emacs.

I considered fetching from git, but it would add a layer of things that I don't fully understand.

So I can simply re-do what I with 28.1 (with minor changes as Philip warned about), and the new Emacs version will simply replace the old.

Maybe just a short sentence about this can be added to the INSTALL/README files?

Cheers!
Luca

Don't replace but do have both.

Keep Ubuntu emacs on /usr/bin/emacs. Perhaps reinstall that package.

Kepp your compiled emacs on /usr/local/bin/emacs or 
/usr/local/bin/my-emacs or $HOME/bin/emacs


You need to run the configure script appropriately.

I did configure my emacs-30 from source code using:

'./configure'  'CFLAGS=-O2 -g' 'CC=/usr/bin/gcc-13' 
'--with-native-compilation' '--with-json' 
'--enable-link-time-optimization' '--with-x-toolkit=gtk3' 
'--program-suffix=-trunk'

adapt that command to your tastes and settings.

On Linux, choosing between old emacs and youre new one is mostly a 
matter of

configuring your window manager

defining appropriate GNU bash (or Unix shell) functions or aliases to 
run your emacs or Ubuntu emacs

setting a correct $PATH ; mine (set in  ~/.zshrc since my shell is 
zsh.org) 
$HOME/.opam/default/bin:$HOME/bin:$HOME/scripts:/usr/local/bin:$HOME/.opam/default/bin:/usr/bin:/bin:/sbin:/usr/sbin

Does it optimize compilation or the executable?

Anyway I built Emacs with that with gcc 10, and no complains.

Re: Question on updating to 29.1

[PierGianLuca]

Hi everyone,

I'm finally getting around to installing Emacs 29.1 (from the tarball, on Ubuntu 20.04), and was looking at the options listed by Basile. I have some questions or curiosities:

>> '--program-suffix=-trunk'

– I don't have gcc-13, so I'll skip that.

– "--with-native-compilation" what does this do? I imagine it's something not specifically related to Emacs.

– "--with-json" ditto?

– "with-x-toolkit=gtk3" is this option already chosen by default? I see that the Emacs install instructions say

"If you use exclusively X, do not use the PGTK port.  There are a number of respects in which the regular --with-x-toolkit=gtk build works better"

which sounds like "=gtk" is the default


Thank you for any info you can share, and for your patience with someone inexperienced with these kinds of installations!

This feature, added with Emacs 28, enables using libgccjit to compile
"platform native" versions of byte-compiled elisp on the fly.  Many
people find it improves Emacs performance, especially for computation
heavy work.

This compiles Emacs with libjansson, which provides JSON parsing

This build Emacs for use with GTK3, and should be used only if you

Re: Question on updating to 29.1

[PierGianLuca]

Hi Corwin,

Thank you so much for the kind answer!! I've now successfully compiled and installed Emacs 29.1 – and enjoying it! :)

Had never used "--with-native-compilation" before, and I can really see it's faster (or it's just a psychological effect).

I've written down all the help and explanations received here for next time :)

Cheers,
Luca

In recent GNU emacs (30) there is a possibility to compile the Elisp 
code to machine code, using libgccjit.

And libgccjit is a "pseudo"' just in time compiler in recent GCC 
compiler. Documented in https://gcc.gnu.org/onlinedocs/jit/ and existing 
in GCC 12.

(Those wanting a real just in time compiler should consider using the 
GNU lightning library, see https://www.gnu.org/software/lightning/ ; it 
is not GCC related, smaller, but generates slower machine code than 
libgccjit).

>
> – "--with-json" ditto?


  I think it is related to understanding JSON. Using the jansson library 
see http://www.digip.org/jansson/ and https://github.com/akheron/jansson 
and https://www.json.org/json-en.html

Does that happen automatically or do I need to somehow configure
something for this?  I followed this guide:
https://github.com/NapoleonWils0n/cerberus/blob/master/fedora/emacs-build-fedora.org

I'm wondering why Fedora still has only the X11 version of emacs which
doesn't even work right.  Wayland is the default since a while, so
Fedora needs a wayland version.

If you build Emacs with native-compilation enabled (it is not the
default for now), then the compilation itself happens autiomatically,
yes.

You can always invoke ./configure --help to get a list of all the
possible options along with short descriptions to understand the point.

FWIW usually you don't need to pass configure any flags.  Often enough
it will figure out what it can enabled, depending on what dependencies
are available on your system.  I believe --with-native-compilation is an
exception, though I am not certain...

Others have gone into what this is, but the background might be
interesting: While Emacs has had JSON parsing for a while, it was
written in Emacs Lisp and that turns out to have been too low if you are
interested in using packages like Eglot, the built-in LSP client, that
send around a lot of JSON-formatted data.

Whenever I am on an X system, I even prefer using
--with-x-toolkit=lucid, especially if you are the kind of Emacs user
that hides the GUI toolkit (things like the menu, tool or scroll-bar).

Pop-up font size with lucid toolkit (was: Question on updating to 29.1)

[PierGianLuca]

Hi Philip,

Thank you so much for the extra info and explanations! Especially this:

> Whenever I am on an X system, I even prefer using
> --with-x-toolkit=lucid, especially if you are the kind of Emacs user
> that hides the GUI toolkit (things like the menu, tool or scroll-bar).

Indeed I only use a vertical scroll bar, and hide the rest. So now I recompiled and reinstalled with --with-x-toolkit=lucid. It's working nicely so far!

I see that some pop-ups (for example when you hover over some buttons in a customize window) look different. I'd like to decrease their font, which is too big, but I'm not managing to find the appropriate customization item or variable. Does anyone know its name, or if decreasing this font is at all possible?

Cheers,
Luca

Solved: Pop-up font size with lucid toolkit (was: Question on updating to 29.1)

[PierGianLuca]

Hi everyone, found the face: Tooltip (I was looking for "pop" keywords). Rescaling the height parameter solved the problem.

Thanks again everyone for the help with compilation!

It is possible.  You can either use the customize interface:

M-x customize-face RET tooltip RET

and change the height attribute there, or add a line to your init file:

(set-face-attribute 'tooltip nil :height 100)

Sorry, I didn't know this was the policy here. I'm on other mailing lists where this is discouraged instead, to avoid double emails.

AFAIU GNU Mailman can check if a person will have received a response
anyway, and not send you a copy of the message in that case.

But here, on emacs-devel and the bug tracker, wide replies are normal.

A short sentence that basically says there's nothing special to do
when you already have an older version installed?  Why is this needed?
In general, if there's no problem, we don't say in the instructions
that there's no problem ;-)

Now that's interesting: Suppose we have file foobar.el(c) from Emacs 28
installed by "make install" somewhere below, say, /usr/local/...

Suppose further foobar.el got removed in Emacs 29.  Will it be actively
removed from /usr/local/... by a "make install" of Emacs 29?

Not sure whether this is what is worrying the OP, but that (and, more 
generally, version consistency issues) would worry me if used "make
install" to "upgrade" a local installation.

Or have I missed something here?

No.  And there's no need to, see below.

I think you have missed that Lisp files are installed into a
version-specific subdirectory of /usr/local/share/ (as in
/usr/local/share/emacs/29.1/lisp/).  So files installed with some
version of Emacs are in the directory not searched by another version.

The Emacs installation method is designed in a way that allows you to
have several Emacs versions installed on the same system.  Only one of

Thank you, this is very useful information. Wouldn't this be useful in the INSTALL files? or maybe it's already there. I might want to keep one previous version just in case, but no other.

Should I do "make uninstall" for the previous version after I install the new version, or before, or it doesn't matter?

Thanks everyone for your help!
Luca

This is standard GNU structure of Make targets, every GNU project
follows that.  You can find the list of standard targets in the node
"Standard Targets" of the "GNU Coding Standards" document.

I find no reason to duplicate that information in Emacs, as that would
waste space for no good reason, and will not be discoverable enough to
make the difference anyway.  Stuff that "just works" doesn't need any
prominent documentation in the first place.

> Should I do "make uninstall" for the previous version after I install the new version, or before, or it doesn't matter?

It's up to you.  I personally never uninstall old Emacs versions, but
that's because having them makes it easy for me, as an Emacs
developer, to check how old versions behaved in specific situations
and when did a specific bug start to happen.  Another consideration is
that if you upgrade your system, some old versions might not run
anymore, at which time they are just using up disk space, and should
probably be removed.  (In this regard my hat off to Microsoft, because
I still have a Windows port of Emacs 21.4, built 17 years ago, running
just fine on my current MS-Windows system, after several OS
migrations, whereas Trisquel GNU/Linux, for example, tends to break
binaries compiled with older OS versions upon every significant OS
upgrade.)

I was not aware of this feature.  It sounds very useful indeed.  Over the
years, I have routinely done "make uninstall" before upgrading to new Emacs.

Sorry for late.

In my case, i did upgrade from bookworm to sid (Debian distro). Now i
have GNU Emacs 29.1 version.

Like me, you do contact to Ubuntu team with Emacs update.

And i like this emacs 29.1 very much!

Sid is the development version of Debian while Bookworm AKA
Debian 12 is the most recent, stable version of Debian.

I don't know what the reason was for you to use Sid, but if it
is to get a more recent Emacs version it is better to keep the
distribution stable, and install Emacs manually. Then you get
the most recent version of Emacs - i.e. even more recent than
what you get from the Sid repos - while still having the
stable Linux distro beneath it.

Especially since it is so easy ot build Emacs manually.

> Like me, you do contact to Ubuntu team with Emacs update.

What do you mean?

> And i like this emacs 29.1 very much!

If you build Emacs yourself you can get

  GNU Emacs 30.0.50 (build 1, x86_64-pc-linux-gnu, cairo version 1.16.0)
  of 2023-09-08 [commit a2f977d94e0356c7414876e988adedd2ab7b52f2]

and you can configure with --with-native-compilation to make
it much faster. Just try - and you will fly :P

I think that manaual building is not easy. Maybe there is a package
for emacs 29.1 of Ubuntu?

There’s this PPA that hosts the package backported from Debian Sid:

Re: Question on updating to 29.1 (on Ubuntu)

[PierGianLuca]

Hi Byung-Hee,

I actually managed to compile the stable version without any problems on Ubuntu 20.04. Quite happy with the result. I list here some links that have been useful in understanding different aspects of the installation, and then the sequence of commands I used. Many people on this list have been very helpful in understanding several aspects of this.

Cheers,
Luca

# save it in some directory, then open a terminal in that directory


$ sudo apt build-dep -y emacs # to install dependencies needed

$ gcc --version # to check CC version, called [VERSION] below

$ sudo apt install libgccjit0 libgccjit-[VERSION]-dev

$ sudo apt install libjansson4 libjansson-dev gnutls-bin

$ tar -xf emacs-29.1.tar.xz

I am building the latest GNU emacs snapshot everyt day on my Ubuntu 
desktop using the following script. My /usr/src/Editors/emacs contain a 
git clone of GNU emacs. I did install the dependencies (they don't 
change often) e.g. with aptitude build-dep emacs

Thanks for mentioning this, I just now upgraded Debian 11
(bullseye) to Debian 12 (bookworm) now!

After doing that, I had to do

  $ sudo apt-get install build-essential debian-goodies libgccjit-10-dev

before upgrading Emacs.

The distro should do that automatically but, for whatever
reason, in the case of libgccjit-10-dev, it didn't.

if i want latest versions in stable_
* stable is installed on your device
* add backports sources.list
deb http://deb.debian.org/debian bookworm-backports main
* check for package versions available
in tracker [ 1 ]
* emacs 29.1 is available in
bookworm-backports [ stable-bpo aka
debian 12 backports], trixie [ testing aka debian 13 ],
sid [ 2 ]
* if package is not available in stable or
stable-bpo but only in testing or sid
   * i would first install on my spare device
or vm, use it for weeks and ok with it,
i would do dist-upgrade my stable
* as a last resort, or feel confident, or
simply bravely, install sid
