Access to nongnu channel

Access to nongnu channel

[Timothy Washington]

I have created this guix system configuration (minimal working example)
with an "operating-system" declaration in *system.scm*.

(use-modules (gnu)
             (nongnu packages linux))

(operating-system
  (kernel linux)
  (firmware (list linux-firmware))
  (host-name "guix")
  (timezone "America/New_York")
  (locale "en_US.utf8")
  (bootloader (bootloader-configuration
                (bootloader grub-efi-bootloader)
                (targets '("/boot/efi"))))
  (file-systems %base-file-systems)
  (users (cons* (user-account
                 (name "user")
                 (group "users"))
               %base-user-accounts))
  (packages %base-packages)
  (services %base-services))


Note that there's an accompanying *channels.scm* file that provides the
"nongnu" packages.

(list (channel
        (name 'guix)
        (url "https://git.savannah.gnu.org/git/guix.git")
        (introduction
          (make-channel-introduction
            "9edb3f66fd807b096b48283debdcddccfea34bad"
            (openpgp-fingerprint
              "BBB0 2DDF 2CEA F6A8 0D1D  E643 A2A0 6DF2 A33A 54FA"))))
      (channel
        (name 'nonguix)
        (url "https://gitlab.com/nonguix/nonguix")
        (introduction
          (make-channel-introduction
            "897c1a470da759236cc11798f4e0a5f7d4d59fbc"
            (openpgp-fingerprint
              "2A39 3FFF 68F4 EF7A 3D29  12AF 6F51 20A0 22FB B2D5")))))


But trying to reconfigure my guix system with this command, gives the
following error.

$ sudo guix system reconfigure system.scm
guix system: error: failed to load 'system.scm':
ice-9/boot-9.scm:3330:6: In procedure resolve-interface:
no code for module (nongnu packages linux)


I took this approach from David Wilson's guide
<https://systemcrafters.net/craft-your-system-with-guix/full-system-install/>
when
first installing the system. And other's have come across the same issue...
But the `(nongnu packages linux)` module is definitely there (ref
<https://gitlab.com/nonguix/nonguix/-/blob/master/nongnu/packages/linux.scm?ref_type=heads>).
And I have pulled the nonguix channel before using it.

guix pull --channels=channels.scm


But the `guix system recofigure` command doesn't see it. And it's not clear
to me where all the "nongnu" packages agot installed. They are not in
`/gnu/store/`.
What am I missing here? What is the root cause of the error? And how do I
make those external channels available?

Hi Timothy,

Is the 'guix' being invoked with 'sudo' the one created by 'guix pull' (~/.config/guix/current/bin/guix)?  I suspect it isn't.

You can verify with

  $ sudo guix describe

and

  $ sudo which guix

('which' is often not the best answer to 'which binary will run?', but here it is.)

If 'sudo' is invoking a different 'guix' than the one in your user's PATH, you need to configure it to do so or explicitly use

  $ sudo -E guix system reconfigure …

IIRC.  YMMV.  CYA.  IANAL.

Kind regards,

T G-R

Sent on the go.  Excuse or enjoy my brevity.

Re: Access to nongnu channel

[Timothy Washington]

That's interesting. Thanks for your feedback. Using sudo in both
invocations, does a successful "guix pull". But has the same failure on
"guix system reconfigure".

$ sudo guix pull
...

$ sudo guix system reconfigure system.scm
guix system: error: failed to load 'system.scm':
ice-9/boot-9.scm:3330:6: In procedure resolve-interface:
no code for module (nongnu packages linux)


But then calling "guix pull" without sudo, fails

$ guix pull
...

$ guix system reconfigure system.scm
guix system: error: failed to load 'system.scm':
ice-9/boot-9.scm:3330:6: In procedure resolve-interface:
no code for module (nongnu packages linux)


=> However, I seem to get further along when I specify "channels.scm".
After adding "(guix profiles)" to the "use-modules" in system.scm...

(use-modules (gnu)
             (nongnu packages linux)
             (guix profiles))


I get a bit further, where guix can't find another form... *Which package
has "manifest->packages" ?*

$ guix pull --channels=channels.scm
...

$ guix system reconfigure system.scm

You have to learn to recognize this class of error.  It means you failed to 
specify the module containing the definition of (manifest->packages) function.  

I do not use it myself, so I don’t know where it is defined.

Also, your package list construction is clunky and round-about.  I recommend 
taking a look at specification->package+output, if I recall correctly, at 
least.  I have had no issues with listing package variables directly.

I am still in the process of refactoring my module collection, but take a look 
at this file in particular to see a very different style of programming Guix.  

You are free to browse the other files for more inspiration, but be warned not 
to replicate the (@ (module) variable) syntax — it ended up backfiring in a 
most subtle of ways, and now I am undoing weeks of work to remove it.

Re: Access to nongnu channel

[Timothy Washington]

Hey Marek,

I should have updated this earlier. But I did solve this problem with a
cleaner `packages` declaration.

(packages
 (append
  (map specification->package
       '("nss-certs"
         "gcc-toolchain"
         ...))
  (list my-package)
  %base-packages))

Thanks for the feedback. Indeed, for me this is an exercise in learning
Guix and developing my understanding of its modules.

Cheers
Tim
