After compilation completes it’s time to give the new Emacs a shot:
It starts up successfully, and makes a valiant attempt to load my existing Emacs configuration.
I notice some warnings about missing Gtk3 modules in the output:
Gtk-Message: Failed to load module "canberra-gtk-module" Gtk-Message: Failed to load module "globalmenu-plugin"
The first is easy to fix:
$ sudo apt-get install libcanberra-gtk3-dev
The second I can’t find an immediate solution for so I defer it to later. The global menu is still relatively young in GNOME/GTK, so this may be something that resolves itself in the next release of Ubuntu.
The whole point of this reboot exercise is to rebuild my configuration from scratch, so I don’t want Emacs24 loading my existing configuration. I’ll put a switch in my .emacs file to redirect Emacs 24 to a different init file:
(if (< emacs-major-version 24) (load "~/share/.emacs23") (load "~/.emacs24"))
With that change (and the creation of a blank ~/.emacs24), I’ve got a vanilla Emacs 24:
Everything looks good, so I’ll install it to /usr/local:
$ sudo make install
