Emacs 28.2

One-minute read
debian • linux • bookworm • emacs

Now that I have Debian bookworm up to date, I can install Emacs 28.2!

sudo apt build-dep emacs
sudo apt install libgccjit-12-dev
sudo apt install libjansson-dev

cd ~/Downloads
gpg --verify emacs-28.2.tar.xz.sig
cd
tar xf ~/Downloads/emacs-28.2.tar.xz
cd emacs-28.2
./autogen.sh
./configure --with-native-compilation
make -j16
make check
sudo make install

Okay, I think all is well!

❯ which emacs
/usr/local/bin/emacs

❯ emacs --version

Let's try it! I don't want to mess up my .emacs.d directory, so I'll start it plain

❯ emacs -Q

Now, let's double-check the native compilation

M-x describe-variable RET system-configuration-features RET

Keen! Now I think I'll back up the .emacs.d directory and make a new one for Emacs 28. I want to be able to still run Emacs 27 if I have to and I don't think they play nice together.
