Using Guix API in a foreign distribution

Using Guix API in a foreign distribution

[sirgazil]

Hi,

I'm using Guix 20170415.01 (binary installation) on Debian 8, and I was
hoping to use the Guix API by installing the guix package as a normal
user, but it seems Guile can't find guix modules:

----------------------------------------------------------------------

$ guile
GNU Guile 2.2.0
Copyright (C) 1995-2017 Free Software Foundation, Inc.

Guile comes with ABSOLUTELY NO WARRANTY; for details type `,show w'.
This program is free software, and you are welcome to redistribute it
under certain conditions; type `,show c' for details.

Enter `,help' for help.
scheme@(guile-user)> (use-modules (guix packages))
While compiling expression:
ERROR: no code for module (guix packages)

----------------------------------------------------------------------

I'm using Guile from Guix, and I have all the environment variables set
as suggested by "guix package --search-paths". Also, I can install Guile
libraries from Guix and Guile finds them without problems.

So, is anyone able to use the Guix API in this way, or do you have to
clone the Guix repository for that?


Thanks,

It works for me on a foreign distro.  This is what I see:

--8<---------------cut here---------------start------------->8---
marusich@odin:~$ guix package --list-installed | grep guix
guix	0.12.0-6.73a4	out	/gnu/store/3xwb1alcv5xd2zgcxp1d1bqqgv0afxj2-guix-0.12.0-6.73a4

Can you share the output of similar commands on your system?

By the way, I see you're using Guile 2.2.  Does this same problem occur
when using Guile 2.0?  I think Guix is still compiled using Guile 2.0,
so I get warnings when trying to import (guix packages) using Guile 2.2.

Here it is:

$ guix package --list-installed | grep guix
guix    0.12.0-7.aabe    out   
/gnu/store/24fa9898h2aa7k7fcbp67kwrwgrxlgi5-guix-0.12.0-7.aabe
$ env | grep GUILE
GUILE_LOAD_PATH=/home/sirgazil/.guix-profile/share/guile/site/2.2
GUILE_LOAD_COMPILED_PATH=/home/sirgazil/.guix-profile/lib/guile/2.2/site-ccache:/home/sirgazil/.guix-profile/share/guile/site/2.2
$ find -L $(env | grep GUILE | cut -d = -f 2 | tr : '\n' | sort | uniq)
-name packages.scm
$

So, guix modules are available in ".guix-profile/share/guile/site/2.0"
but not in ".guix-profile/share/guile/site/2.2".

No. If I install guile 2.0.14, I can load guix modules just fine.

Hi sirgazil!

sirgazil <sirgazil@zoho.com> skribis:

This is because the ‘guix’ package in Guix currently builds against
Guile 2.0, not 2.2.

The reason for this is that one of its dependencies, Guile-SSH, is not
2.2-ready yet; I’ve submitted patches to fix that a few days ago so
hopefully that’ll be resolved very soon!

HTH,
Ludo’.

Good. No problem then :)
