Hi rde community,

Any idea why my channel fails to find the meow module?

I get the following error:

(repl-version 0 1 1)
(exception misc-error (value #f) (value "no code for module ~S") (value ((confetti features meow))) (value #f))

https://git.sr.ht/~whereiseveryone/confetti

I'm completely stumped on why this is. 

I'm able to build and use the modules locally but when I push my config to the channel repo and pull it fails with the above error.

It was not able to find the chatgpt module either with the same/similar error when imported into my conf.scm.

Any help is much appreciated.

all best,

jgart

Provide a command/instruction to reproduce, please.

Hi Andrew,

Add the confetti channel to your channels.scm and do a guix pull.

That will reproduce the error and give you a failing build log similar to the following for inspection:

|builder for `/gnu/store/ij76gfks9z1gn6rci1y7wqp1w3anrhjx-confetti.drv' failed to produce output path `/gnu/store/s0mqamz60r3h0dcharafdrrgqr72m2dz-confetti'
build of /gnu/store/ij76gfks9z1gn6rci1y7wqp1w3anrhjx-confetti.drv failed
View build log at '/var/log/guix/drvs/ij/76gfks9z1gn6rci1y7wqp1w3anrhjx-confetti.drv.gz'.
cannot build derivation `/gnu/store/ii8ccwg5xj6psc94g0rkf985zal2il5r-profile.drv': 1 dependencies couldn't be built

Here's the channel record to reproduce that:

(channel
    (name 'confetti)
    (url "https://git.sr.ht/~whereiseveryone/confetti")
    (branch "s")
    (introduction
     (make-channel-introduction
      "e037ffa3a40bcd7807a97a0415ef588b411277c3"
      (openpgp-fingerprint
       "3B1D 7F19 E36B B60C 0F5B  2CA9 A52A A2B4 77B6 DD35"))))

The commit that is failing is the following:

This is because you have `(directory "confetti")` in your channel
declaration:
https://git.sr.ht/~whereiseveryone/confetti/tree/s/item/.guix-channel#L3

It tries to find confetti/features/meow.scm in confetti/ directory.

Either put confetti/ under src/ and set directory to "src" or
set directory to "." (which I don't recommend).

Hi Andrew, can you explain why you don't recommend "."? I'm not sure why to avoid it.

Sure.  Using "." makes it impossible to have a few subdirectories, which
can be conditionally used (included in the %load-path) for different use
cases, for example "src/" "tests/" "dev/", last two useful for
development, but not need in resulting build/channel or whatever guile
artifact you want to provide.

Also "." will capture some auxiliary files like channels.scm or
something else, which usually is not a desired behaviour as well.
