Emacs 28 and Doom Emacs Setup Guide

Goal

Build Emacs 28 from source code and install Doom Emacs

Install Emacs

Checkout sourcecode

git clone https://github.com/emacs-mirror/emacs.git
cd emacs
git checkout emacs-28

Install dependency packages

On Pop!_OS 20.04

Library packages needed for a plain ./configure

• texinfo
• gnutls-dev
• libncurses-dev
• libtinfo-dev
• libwebkit2gtk-4.0-dev

In summary, the following two commands should do

sudo apt install libxpm-dev libgif-dev libjpeg-dev libpng-dev libtiff-dev libx11-dev libncurses5-dev automake autoconf texinfo libgtk2.0-dev
sudo add-apt-repository ppa:ubuntu-toolchain-r/ppa
sudo apt install gcc-10 g++-10 libgccjit0 libgccjit-10-dev libjansson4 libjansson-dev

Configure and Build

export CC=/usr/bin/gcc-10 CXX=/usr/bin/gcc-10
./autogen.sh
./configure --with-native-compilation --with-json --with-xwidgets
make -j$(nproc)

Install Doom Emacs

Checkout the official page first, the installation steps may change: https://github.com/hlissner/doom-emacs

I use the following two commands:

git clone --depth 1 https://github.com/hlissner/doom-emacs ~/.emacs.d
~/.emacs.d/bin/doom install

Install Private Config

If you have private configs in different repos like me, you should also check out that and put it under ~/.doom.d directory.

Remember to sync the private configure to doom first by ~/.emacs.d/bin/doom sync
