Hi Guix,

Reporting as instructed. I stripped down this line

   error: #{\x0;\x0;\x0;\x0}#: unbound variable

In reality, “\x0;” inside the braces is repeated maaaaaaaany times.

The error persists after disabling my “guix-wz” channel.

Using Guix 00ff6f7 and running,

--8<---------------cut here---------------start------------->8---
$ guix time-machine --commit=86ec52f66735b122b9035eba56516fd16f3be958 \
     -- time-machine --commit=c07b55eb94f8cfa9d0f56cfd97a16f2f7d842652 \
     -- help
--8<---------------cut here---------------end--------------->8---

then it works for me.


Cheers,

Hi simon,

This doesn’t work for me, of course.

This

   guix time-machine --commit=67a204920285adaf5603da1bc5cc13726cbef191 -- help

works.

One commit later

   guix time-machine --commit=08f2a06d261ad7a91b3f4df83a5093b8a28f15ed -- help

fails.

The commit is “gnu: Add guile-dns.” Kind of makes sense that it is
guile-related.

It means it is on your side and not on Guix side, of course. :-)

Are you sure the error is not coming from your local channel named
guix-wz?

From you initial bug report, the error seems because some Perl package.
And it would appear to me weird that the error would be from the
addition of the package guile-dns.

simon

I’m not sure. However, I did

   sudo su -
   # guix pull

and ran into the same issue, even though root does not use guix-wz.

I reverted the above commit in a local clone and tried pointing
guix to the clone

   guix pull --url=… --commit=… --disable-authentication

Same problem.

I also build guix from the source and tried, in vain

   ./pre-inst-env guix pull

There was one package with perl as a native-input. I removed it, and
nothing changed. Moreover, from the bug report:

   222:17 10 (map1 (((gnu packages perl)) ((gnu packages python)) ((gnu packages m4)) ((gnu packages man)) ((# ?)) ?))

I don’t use m4 and man modules anywhere. However, the sequence
perl-python-m4-man occurs in gnu/packages/autotools.scm of Guix proper.

Yes, I agree.
