branch feature/native-comp

[AW]

Hi!

OS: Linux, Tumbleweed by openSUSE

1) Is there somewhere a description of the git branches of emacs at http://
git.savannah.gnu.org/cgit/emacs.git ?

2) Linux on desktop is moving towards wayland. As far as I understand it 
(probably completely wrong), this is done with a kind of GTK-Emacs. 

There is a pure gtk feature branch, "feature/pgtk". I compiled it and it works 
under "pure" wayland. 

By the way, "./configure --with-native-comp" didn't work (no surprise). 

But there is also a branch feature/native-comp, which doesn't work under 
wayland. I checked this branch out as well, compiled it, installed it, but no 
fun: At least I always get the GTK error "cannot open display: 1". But in 
a x11 environment (KDE Plasma) in a short test there were no issues. 

As far as I understand it, sense of the latter branch is to speed up Emacs. 
And that makes me curious...

Is there a way to get this native-compiled feature into an Emacs working under 
wayland?

Regards,

Alexander

AFAIK, no.

It is --with-nativecomp, but see below.

The native-comp branch is not merged with into pgtk branch (nor into
master, so --with-nativecomp only works on the native-comp branch (and
that option is required to enable the feature)), so right now neither
branch contains those two features.

You can try creating a new branch that merges those two.

Somebody already did that. I got the hint here: 

https://deathwish.info/2020/08/01/pgtk-nativecomp/

and the source is here: https://github.com/fejfighter/emacs

Cloned with 

git clone -b pgtk-nativecomp https://github.com/fejfighter/emacs

and compiled, works! Got lots (354) of *.eln files in ~/.emacs.d/eln-chache 

@Óscar: Thank you very much, because the option for configuring was, as you 
mentioned, --with-nativecomp !

For the impatient: the main work was to get libgccjit onto my system.
