So why did it fix it for Emacs?

Upgrading did the trick.

If I get it right, updating glibc or the locales does not trigger an
upgrade of all packages that were built with older versions, hence the
issue.

Should Guix packages depend on glibc so that an upgrade of glibc
upgrades all glibc-dependent packages?

Duh!  That was so obvious, I completely forgot I wasn't "installing" :p

The problem is gone for Emacs (hurray!) but not for stow.

What does it mean?  That glibc _must_ be installed on all user profiles?

That’s expected.  “guix build” doesn’t install anything and so the
executables of built packages don’t automatically end up in PATH.
That’s by design.

Glibc was not installed, but installing it pulls 3 packages:

This looks good.  Let's rewind for a bit.  The original error message
was:


> stow .
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LANGUAGE = (unset),
LC_ALL = (unset),
LANG = "en_US.utf8"
are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").

Using the fallback 'C' locale.

Can you post the output of these commands in a terminal:

$ locale
$ env | grep LOCPATH
$ ls -l /run/current-system/locale/

This is too bad, I believe it's an important feature for any package
manager.
As far as I can tell, `portage` and `pacman` can both do it.

Any plan regarding guix?

Running `guix package -u emacs` does nothing special, possibly because
it's already up to date.  Can I force a rebuild?

"ldd" is in "glibc" :-)

You can also use `guix gc -R /gnu/store/...-emacs-25.3 | grep glibc`.

Guix does not currently know anything about the files inside each
package, I typically do a web search...

This situation can occur when you've installed emacs built against glibc
2.25 (which was the glibc in Guix until ~February), and then later
updated "glibc-utf8-locales" to 2.26 which has incompatible locale data.

Updating emacs would fix it in that case, since it would be built
against the new glibc.

On GuixSD, you can use the 'locale-libc' operating-system parameter to
install locale data for multiple glibc versions to ease transition
between glibc updates.

On GuixSD this should work fine out of the box.  On other distros,
please take a look at

HTH!
