Hello,

ludo <at> gnu.org (Ludovic Courtès) skribis:

> Indeed, on closer inspection, (guix config) is miscompiled and looks for

It turns out the ‘define-module’ form has to be spliced in 2.0.

Fixed in commit eb72cdf087fe51d85e0c1514ec8e669047b5d6e1.

Thanks Ricardo & Alex,
Ludo’.

Hello Guix,

Commit eaae07ec2878707744fed76029a28ab9a494fc2e breaks 'guix pull' for
guile 2.0 users. More precisely, it fails with:

================================================================================


The relevant error is:

================================================================================
./guix/self.scm:80:4: Throw to key `match-error' with args `("match" "no matching pattern" "guile <at> 2.0")'.
================================================================================

I think the error is caused by the pattern matching code not taking into
account the version suffix. Also, I have used 'guix pull --commit ...'
to make sure it is really eaae07ec2 causing the problem.

Cheers,
Alex
