Hi,
I would like to use the Guix.el from the Git repository of Guix, but I
fail at configuring it. I use Guix 0.9.0 built from source ontop of
Debian and installed with standard the “/usr/local” prefix.
It works perfectly with Guix.el from “/usr/local/share/emacs/site-lisp”
with the configuration describe in the manual:
(add-to-list 'load-path "/usr/local/share/emacs/site-lisp")
(require 'guix-init)
But when I try to replace this with the “Hacking” configuration from the
manual:
(let ((dir "~/src/gnu/guix/emacs"))
(add-to-list 'load-path dir)
(setq guix-load-path dir))
(require 'guix-init nil t)
I get this error when launching ‘M-x guix’:

Hm, all I can say: this configuration works for me.

So Guix REPL is dead after this, right? It looks like your
"~/src/gnu/guix/emacs" is not appended to guile %load-path (it is done
in `guix-start-repl' by cons-ing `guix-load-path' to
`geiser-guile-load-path').
Could you check "C-h v guix-load-path" to be sure that its value is
really "~/src/gnu/guix/emacs". Also just in case, show the value of
`guix-helper-file' variable.

It is.

guix-load-path is a variable defined in `guix-backend.el'.
Its value is "~/src/gnu/guix/emacs"
--8<---------------cut here---------------end--------------->8---

guix-helper-file is a variable defined in `guix-backend.el'.
Its value is "/home/mthl/src/gnu/guix/emacs/guix-helper.scm"
--8<---------------cut here---------------end--------------->8---
These two variables helped me figure out that the problem was the use of
“~” in:
(let ((dir "~/src/gnu/guix/emacs"))
...
When changing it with “/home/mthl” it works! To avoid this kind of
mistake in the future, a simple fix would be to change the example in
the documentation, with:
(let ((dir "/absolute/path/to/your-guix-git-tree/emacs"))
...
But is there a way to change the implementation to let users use
relative path?
Thanks,

Ouch, my bad, sorry. Yes, IIUC Guile %load-path should contain absolute
directories, and as Geiser does not expand the contents of
`geiser-guile-load-path', this "~/..." string literally goes to
%load-path.

Yes, the fix is easy. The patch is attached, could you confirm that it
works?
Thank you for finding the root of this bug!
