--8<---------------cut here---------------start------------->8---
$ guix graph --path emacs xz
emacs@27.2
libxml2@2.9.12
xz@5.2.5
--8<---------------cut here---------------end--------------->8---
Note that
--8<---------------cut here---------------start------------->8---
(source (origin
(method url-fetch)
(uri (string-append "mirror://gnu/emacs/emacs-"
version ".tar.xz"))
--8<---------------cut here---------------end--------------->8---
but I do not see ’xz’ in the implicit inputs; only emacs-minimal. Quick
look, maybe I miss it.
Well, indeed, something seems unexpected if the Emacs binary is linked
to liblzma and this liblzma is not an explicit inputs but instead comes
from a reference to another inputs.
Cheers,
