I'm not an expert on Guile or the new `guix pull`. However, I think that
`guix pull` takes its Guile from the environment, because `guix pull -l`
doesn't work for me when there is no Guile in PATH.

Those errors look like a mismatch between Guile versions 2.0 and 2.2.
Which Guile do you have available in the environment where you see that
error?

As root user, it's guile <at> 2.0.14. Indeed, installing guile <at> 2.2.4 from Guix fixes
the problem. Thanks for your insight. :)

I thought Guix is self-contained, so are you implying that Guix itself is not
reproducible?  Is it reasonable to request making Guix self-contained?

Thanks.

Great!

By the way, Guix *does* work with Guile 2.0. The messages you saw should
not prevent using Guix. Guix was using Guile 2.0, which was finding some
pre-compiled Guile 2.2 objects. Guile 2.0 printed those messages to say
that it did not recognize the precompiled objects and had to recompile
them.

Guix is not self-contained. Its dependencies are listed in the manual:

https://www.gnu.org/software/guix/manual/en/html_node/Requirements.html

As for whether or not it could or should be self-contained, answering
that is outside of my expertise.

I think there is no bug to fix here, right? Please re-open the bug if I
am wrong.

What command did you run to get the errors about?  Could you also show:

  which guix
  echo $GUILE_LOAD_PATH
  echo $GUILE_LOAD_COMPILED_PATH

?

The new ‘guix pull’ provides a “self-contained Guix” in the sense that
it brings all its dependencies, including Guile.  If you look at the top
of the ‘guix’ file, you’ll see that it specifies exactly the Guile
version that it needs:

--8<---------------cut here---------------start------------->8---
$ head -1 ~/.config/guix/current/bin/guix
#!/gnu/store/p9wm67w3rfw3hlb9iljgvsfn84mz4w9d-guile-2.2.4/bin/guile --no-auto-compile
--8<---------------cut here---------------end--------------->8---

Thus, Guile version mismatches like you experienced should normally not
happen.

Thanks for your report,
Ludo’.

I tried the following commands after switching back the package profile to
previous state.

$ which guix
/root/.config/guix/current/bin/guix

$ echo $GUILE_LOAD_PATH
/root/.guix-profile/share/guile/site/2.2

$ echo $GUILE_LOAD_COMPILED_PATH
/root/.guix-profile/lib/guile/2.2/site-ccache:/root/.guix-profile/share/guile/site/2.2

But I can't reproduce the bug now since I cleaned up all profiles in pull.

Alright.  Probably you were using a different ‘guix’ command back then.
Closing!
