An interesting update: If you try to make sure that Emacs is rebult, even using the same/current package definition, then the result works as expected.
In my case, I made a local package definition for Emacs, and changed the phases or snippet enough to modify the source files a little, like so: Before: --8<---------------cut here---------------start------------->8--- (with-output-to-file (string-append lisp-dir "/site-start.el") (lambda () (display (string-append "(when (require 'guix-emacs nil t)\n" " (guix-emacs-autoload-packages))\n")))) --8<---------------cut here---------------end--------------->8--- After: --8<---------------cut here---------------start------------->8--- (with-output-to-file (string-append lisp-dir "/adfeno-dummy.el") (lambda () (display (string-append "(print \"adfeno\")\n")))) (with-output-to-file (string-append lisp-dir "/site-start.el") (lambda () (display (string-append "(when (require 'guix-emacs nil t)\n" " (guix-emacs-autoload-packages))\n")))) --8<---------------cut here---------------end--------------->8--- Notice that I didn't change the "before" part, I just added a code that simply creates a file called "adfeno-dummy.el". Now, I wonder how to tell `guix package' to install what was just built? At any case, I hope this helps. ;) 2017-11-12T11:56:43-0800 Mason Hock wrote: > I have installed emacs with Guix.
