Re: ASDF Builder (Common Lisp) & "package-inferred-system" Packages

[Pierre Neidhardt]

Hi!

It's been a while, and now that I'm on the verge of releasing Next 1.3
and a dependency is a package-inferred-system, I thought it would be the
perfect time to dig out this issue! :)

So I'm trying to package cl-dbus (https://github.com/death/dbus).
You'll find the recipes here: 
https://gitlab.com/atlas-engineer/next-guix-channel

I can package it in several ways, but the result does not work for the
reasons mentioned in this topic.

I thought of the following trick: what about just dumping the full source
into "/lib/sbcl"?  Wouldn't that work?
Do we really need the .fasl files?

When I try to build Next with dbus packaged using this last trick, it
actually gets quite far, until it complains about circular dependencies:

I've asked for help on ASDF issue tracker:

https://gitlab.common-lisp.net/asdf/asdf/issues/10


By the way, there they confirmed that using `*source-registry*` is the
right way to go.  Note that this is _not_ the same variable as
`*source-registry-parameter*` that Katherine mentioned.

So we are good on that front.

Thoughts?
