[Jeremy Korwin-Zmijowski]

Hey Guixters !

I am still building my dummy package definition. I restarted some steps
back and know I am facing something weird to me :

   $ echo \
   '(use-modules
    (guix packages)
    (guix build-system emacs)
    (guix licenses)
    (guix git-download))
   (package
    (name "")
    (version "")
    (source
     (origin
      (uri (git-reference (url "") (commit "")))
      (method git-fetch)
      (sha256 (base32 ""))))
    (build-system emacs-build-system)
    (synopsis "")
    (description "")
    (license bsd-3)
    (home-page ""))' > /tmp/dummy-package-definition.scm

   $ ./pre-inst-env guix build -f /tmp/dummy-package-definition.scm 
   ice-9/eval.scm:142:16: In procedure compile-top-call:
   error: git-reference: unbound variable
   hint: Did you forget `(use-modules (guix git-download))'?

Do you know why Guix doesn't see my import ?

Hi!

Actually I don't get this error.  I get

--8<---------------cut here---------------start------------->8---
guix build: error: derivation `/gnu/store/78dk4v22xwzxrvl7wrjl1g67qrf1yd37-git-checkout.drv' has incorrect output `/gnu/store/7ygy97wz9d1zcbz3k2kg1ga9g389bd7b-git-checkout', should be `/gnu/store/mnkrx2xpxnqaizmylyya8ilvmym7w0b7-git-checkout'
--8<---------------cut here---------------end--------------->8---

This is because the URL cannot be empty.
Beyond that, you must specify a name and a version if I'm not mistaken.

Hi Pierre !

Thank you for the feedback of your test. And the insight.

I did it with a recent guix built from sources.
But could be something wrong with my operating procedure...

Hi Jérémy,

I also get the same error as Pierre, and I copied your file precisely, on a recent guix. I don't think specifying a URL will help, but specifying a hash definetely does. To get a valid hash (but not necessarily the one you are looking for), you can use "guix hash <some-file>". This allows the baild process to start here, although it fails to download anything apart from build-system packages, of course.

Hello Guixters!

Hope you are doing well. 

Thank you, Pierre and Julien, for your answers.

I am still looking for a convenient (but almost clean) way to work on
my package definition. Maybe I push it too much, I don't know.

I freshly cloned and built Guix from sources this morning. And I still
encounter this strange behavior... Which I don't when I am in a pure
environment...

   $ guix environment --pure guix
   [dev]$ echo '(use-modules (guix packages) (guix build-system emacs)
   (guix licenses) (guix git-download)) (package (name "") (version "")
   (source (origin (uri (git-reference (url "") (commit ""))) (method
   git-fetch) (sha256 (base32 "")))) (build-system emacs-build-system)
   (synopsis "") (description "") (license bsd-3) (home-page ""))' >
   /tmp/dummy-package-definition.scm
   [dev]$ ./pre-inst-env guix build -f /tmp/dummy-package-
   definition.scm
   guix build: error: derivation
   `/gnu/store/fkr651kwnllq46550ml6qjavi015d21d-git-checkout.drv' has
   incorrect output `/gnu/store/7ygy97wz9d1zcbz3k2kg1ga9g389bd7b-git-
   checkout', should be `/gnu/store/0fd9p27axy1jdw7fv29fa8i3sa0vajbl-
   git-checkout'
   [dev]$ ^C
   [dev]$ exit
   $ echo '(use-modules (guix packages) (guix build-system emacs) (guix
   licenses) (guix git-download)) (package (name "") (version "")
   (source (origin (uri (git-reference (url "") (commit ""))) (method
   git-fetch) (sha256 (base32 "")))) (build-system emacs-build-system)
   (synopsis "") (description "") (license bsd-3) (home-page ""))' >
   /tmp/dummy-package-definition.scm
   $ ./pre-inst-env guix build -f /tmp/dummy-package-definition.scm
   ice-9/eval.scm:142:16: In procedure compile-top-call:

Here is the Guix version from source :

   $ ./pre-inst-env guix --version
   guix (GNU Guix) 1.0.1.12434-51f30-dirty

And the one on my system :

   $ guix --version
   guix (GNU Guix) 4f236f84a964c5d7071a08407f5b602dcb14c8ad

I am running on Ubuntu 18.04.4 LTS

Is their any reason, any bug in my process ?
