Running from source: `Component "swank/exts" not found`

[Soham Chowdhury]

Describe the bug
Following the recipe in the developer manual produces the following error in *Nyxt Guix shell compilation* after some time at the C-u - M-x sly RET nyxt-sbcl RET step:

debugger invoked on a ASDF/FIND-COMPONENT:MISSING-COMPONENT in thread

Doing guix shell -D -f build-scripts/nyxt.scm -- sbcl and then (asdf:load-system :nyxt/gi-gtk) has the same effect, so it's not an Emacs-specific issue.

Information

• OS name+version: NixOS unstable
• How you installed Nyxt (Guix pack, package manager, build from source): source
• Information from show-system-information:
  • Nyxt version (from the nyxt-version command or nyxt --version from a shell): 655588b4981e2dd9ea0c736be980e75defd61261
  • Lisp implementation/version (if built from source): SBCL 2.4.0
  • Kernel name+version: Linux 6.7.12 #1-NixOS SMP PREEMPT_DYNAMIC

@evertedsphere it seems that the issue is related to the fact that Guix isn't up-to-date. Can you run guix pull and then try again?

[Soham Chowdhury]

@aadcg tried it a few times since then, git pull --recurse-submodules and guix pull followed by running (asdf:load-system :nyxt/gi-gtk) in the REPL consistently produces the same error.

Could it have to do with my Guix setup? I installed it so I could use Nyxt, but I don't know much about it otherwise. I do have the PATH set up correctly, as far as I know:

$ which guix
/home/s/.config/guix/current/bin/guix

and my ~/.config/guix/channels.scm contains (only) the snippet in the Nonguix readme.

The git submodules are irrelevant when the development environment is done via Guix. In other words, the swank/exts system is coming from Guix, not from the git submodules. That's why I maintain that your Guix instance isn't up-to-date. What's the output of guix install emacs-slime --dry-run? It should output emacs-slime 2.29.1.

and my ~/.config/guix/channels.scm contains (only) the snippet in the Nonguix readme.

Assuming you're using the default channel and nonguix, the channel file (at ~/.config/guix/channels.scm) should look along the lines below:

(use-modules (guix ci))

(list (channel
       (name 'nonguix)
       (url "https://gitlab.com/nonguix/nonguix")
       (introduction
        (make-channel-introduction
