That is an interesting and surprisingly difficult to debug error you
have there.  On Guix System, we have
--8<---------------cut here---------------start------------->8---
$ ldd $GUIX_ENVIRONMENT/bin/.emacs-27.2-real | grep lzma
	liblzma.so.5 => /gnu/store/c8isj4jq6knv0icfgr43di6q3nvdzkx7-xz-5.2.5/lib/liblzma.so.5 (0x00007f7919fee000)
--8<---------------cut here---------------end--------------->8---
where xz is one of those magic libraries you'd expect to exist in any
distro.  However,

--8<---------------cut here---------------start------------->8---
$ guix show emacs | recsel -p dependencies

If at all, xz is included as implicit input to unpack Emacs!  We should
probably add it as explicit input instead.

--8<---------------cut here---------------start------------->8---
$ guix graph --path emacs xz
emacs <at> 27.2
libxml2 <at> 2.9.12
xz <at> 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.

Using bec806e from yesterday, I cannot reproduce on Ubuntu.  The invokation

    guix shell -C -E DSISPLAy -E TERM emacs --  emacs -nw

works for me.  I suspect something wrong with your environment
variables.  Maybe you could run "guix shell --check".

Thanks for investigating, I did not consider ‘guix graph’.

IIRC, it'd be quite deep in the unpack chain, but maybe I'm mixing
things up as well.

I think that's what you'd observe on other distros as well.  IIRC the
linker ought to correctly resolve/"propagate" such dependencies, so it
shouldn't be a problem.

Vicente, could you check the output of ldd for your Emacs, as well as
libxml2 and also check whether your xz package is perhaps broken and
ought to be repaired?

I did it just after guix pull. I cannot check the revision as I did it in my work computer, I will check it tomorrow.

I am not Vicente but mine looks like with Guix ff093f5 on Debian.

--8<---------------cut here---------------start------------->8---
$ guix shell libxml2
[env]$ ldd $GUIX_ENVIRONMENT/lib/libxml2.so | grep lzma
	liblzma.so.5 => /gnu/store/aggsb6j1svxp70xlll4rqnx5f2pzz794-xz-5.2.5/lib/liblzma.so.5 (0x00007fee6026e000)
--8<---------------cut here---------------end--------------->8---

and

--8<---------------cut here---------------start------------->8---
$ guix shell emacs
[env]$ ldd $GUIX_ENVIRONMENT/bin/.emacs-27.2-real | grep lzma
	liblzma.so.5 => /gnu/store/c8isj4jq6knv0icfgr43di6q3nvdzkx7-xz-5.2.5/lib/liblzma.so.5 (0x00007f134d7e3000)
--8<---------------cut here---------------end--------------->8---

Ah!  It is not the “same“ xz. :-) Well, it probably does not come from
libxml2 (except if there is a graft).

Anyway, I suspect something wrong with Vicente’s ’env’.

simon

Looking at the derivations,
/gnu/store/c8isj4jq6knv0icfgr43di6q3nvdzkx7-xz-5.2.5/ is built with all
our mesboot stuff, whereas /gnu/store/aggsb6j1svxp70xlll4rqnx5f2pzz794-
xz-5.2.5 is not.  In other words, I suspect that it is indeed
Schrödinger's missing dependency :P

Could you check whether the ‘LD_LIBRARY_PATH’ environment variable is
defined, for instance by running:

  env | grep LD_LIBRARY_PATH

If it is, please unset it:

  unset LD_LIBRARY_PATH

Does it help?

Since we haven't heard back from Vicente, I presume their problem has
been resolved somehow.

Closing.
