Building Emacs from Source

I suppose it was bound to happen sooner or later, the following is a simple script for building Emacs from source and installing it under ${HOME}/.local

#!/bin/bash
set -eux

SRC="${HOME}/Projects/gnu/emacs/master"
PREFIX="${HOME}/.local"

pushd "$SRC"

# Install build dependencies...
sudo dnf builddep -y emacs

./configure \
    --prefix="${PREFIX}" \
    --disable-gc-mark-trace \
    --with-pgtk \
    --with-native-compilation=aot \
    --without-x

read -p "Continue? [y/N] " -n 1 -r

if [[ $REPLY =~ ^[Yy]$ ]]
then
    make -j $(nproc)
fi

Using Aurora as my OS poses a few challenges, so in order to make the above work

• The build itself was executed in a fedora distrobox

• I still have the fedora emacs package layered:

  $ rpm-ostree status
  State: idle
  AutomaticUpdates: stage; rpm-ostreed-automatic.timer: no runs since boot
  Deployments:

  I have not un-layered the package to test it, but my assumption is that this enables the version of Emacs I compile to work by ensuring all the runtime dependencies are present.
