Emacs 27 and Doom Emacs Setup Guide

Goal

Build Emacs 27 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-27

Install dependency packages

On Pop!_OS 20.04

Library packages needed for a plain ./configure

• texinfo
• build-dep inkscape (for gtk+)
• libxpm-dev
• libgif-dev
• gnutls-dev
• libncurses-dev
• libtinfo-dev
• libwebkit2gtk-4.0-dev

In summary, the following two commands should do

sudo apt install autoconf texinfo libxpm-dev libgif-dev gnutls-dev libncurses-dev libtinfo-dev libtiff-dev libjpeg-dev libgtk-3-dev libwebkit2gtk-4.0-dev
# sudo apt build-dep inkscape

Configure and Build

./autogen.sh
./configure --with-xwidgets
make -j48

To make building quicker, I use make -j48 for a 16-core system. Roughly 1.5 times of the total cores available (including hyper threads).

Install DoomEmacs

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
