Installing emacs 26.3 from source on Ubuntu v18.04

These appear to be the minimum number of libraries which need to be installed to get Emacs running:

sudo apt-get install libgtk-3-dev \
     libxpm-dev \
     gnutls-dev \
     libncurses5-dev \
     libx11-dev \
     libxpm-dev \
     libjpeg-dev \
     libpng-dev \
     libgif-dev \
     libtiff-dev \
     libgtk2.0-dev

The apt-get build-dep emacs25/emacs24/emacs command(s) did not seem to work without adding a particular source.

The next step is to download the latest emacs source. As such v26.3 is a reasonable version to have for the foreseeable future.

mkdir ~/source/
cd ~/source
wget "http://ftp.gnu.org/gnu/emacs/emacs-26.3.tar.gz"
tar xf emacs-26.3.tar.gz
cd emacs-26.3
./configure
make 
sudo make install
