1. Requires packages

   sudo apt-get install libxaw7-dev libxpm-dev libpng12-dev libtiff5-dev libgif-dev libjpeg8-dev libgtk2.0-dev libncurses5-dev libdbus-1-dev libxft-dev texinfo libgnutls-dev libgnutls28-dev libjpeg62-turbo-dev
       

2. Install requirements for emacs xwidgets to work

   sudo apt-get install libwebkitgtk-3.0-0 libwebkitgtk-3.0-dev
       

3. Clone from git like so

   git clone --depth 1 https://github.com/emacs-mirror/emacs.git
       

4. Compile (Note xwidgets may not work on your machine)

   ./autogen.sh
   ./autogen.sh git
   ./configure --prefix=/opt/emacs --with-xft --with-xwidgets --with-imagemagick
   make -j32
       

5. Start

   src/emacs
       

6. Install

   sudo make install
       

7. Update alternatives to use the new emacs & set the priority to 100 so it’s automatically selected

   sudo update-alternatives --install /usr/bin/emacs emacs /opt/emacs/bin/emacs 100
   sudo update-alternatives --install /usr/bin/emacsclient emacsclient /opt/emacs/bin/emacsclient 100
       

8. Configure the alternatives

   sudo update-alternatives --config emacs
   sudo update-alternatives --config emacsclient
       

9. Manually check alternatives are correctly set

   ls -al /etc/alternatives | grep emacs
       

10. Manually check bin directory is correctly set

    ls -al /usr/bin | grep emacs
        

11. Start the new emacs

    emacs
        

12. Start package listing and accept certificates using ‘a’

    M-x package-listing
        

13. Start emacs & install use-package

    M-x package-install
    use-package
        

14. Restart emacs & install pdf-tools

    C-x b
    compile-pdftools (respond with Y) (also M-x pdf-tools-install then exit & restart emacs answer Y to reinstall prompt on restart)
        

15. Restart a number of times until everything is starting correctly.

(Optional fix) Create/update symlinks if they are pointing to an old emacs version

ln -s -f target symlink_name #update existing symlink
