help setting up guix from source

Hi,

I've been following Guix from it's initial release and finally found
some time to play with it (actually, second time). I believe both Guix
and GuixSD are fantastic and exciting projects. Kudos to Ludovic and
the rest of the team!

I was trying to make Guix run from the source code, but have found some issues.

First one was this step:

https://www.gnu.org/software/guix/manual/guix.html#Locales-1

When I run "guix package -i glibc-locales" after setting up the daemon I get:

substitute: updating list of substitutes from 'http://hydra.gnu.org'... 100.0%

over and over. If I make it verbose, I can see things like:

substitute: updating list of substitutes from 'http://hydra.gnu.org'... 100.0%
|   |   substitution of
`/gnu/store/2w1n3ary5sy2z4m094lmw8gjli962l87-patch-2.7.5.tar.xz':
trying next substituter
|   |   path `/gnu/store/2w1n3ary5sy2z4m094lmw8gjli962l87-patch-2.7.5.tar.xz'
is required, but there is no substituter that can build it
|   |   substitution of
`/gnu/store/2w1n3ary5sy2z4m094lmw8gjli962l87-patch-2.7.5.tar.xz': done
|   |   building of
`/gnu/store/viqpy1k0sc8az90z2df1rln9598z613x-patch-2.7.5.tar.xz.drv':
waitee `substitution of
`/gnu/store/2w1n3ary5sy2z4m094lmw8gjli962l87-patch-2.7.5.tar.xz''
done; 0 left

It ends up with a big error (log file attached). I have also tried to
install other packages without luck.

Another thing that I tried to do was "guix package -l", but it gives me:

guix package: error: profile
'/usr/var/guix/profiles/per-user/aleix/guix-profile' does not exist

rekado on the IRC says this will be created as soon as I install a
package. May be it should be more explicit in the documentation:

https://www.gnu.org/software/guix/manual/guix.html#Package-Management

Or may be it could be created when trying to list the generations even
if no package has been installed?

My apologies if I missed something obvious. I believe I read
everything in the manual until getting stuck in these steps.

Thanks!

Aleix

In case anyone wonders, all my problems went away after authorizing
hydra's public key and binary substitute were available. See:

For the record, the fact that this line is displayed several times in a
row is a side effect of the recent introduction of grafts¹.

I’m thinking of improving parallelism and/or increasing caching to
mitigate that.

HTH,

About parallelism, I believe (may be I'm wrong) downloads occur
sequentially right now, I think running them in parallel would speed
up things as well.

It’s not entirely clear to me, but you could try by increasing the
number of jobs, as in:

  guix build libreoffice --max-jobs=4

The default is one job at a time (but each job can use all the cores.)

Thanks,
Ludo’.
