I tried a later version (3.2 or 3.3, I forget which) and adg fails to load. I think I'll stick w/ the last known working version until I sort out getting it to run ...
It loads perfectly for me: sbcl --eval "'(#.(require :asdf) #.(in-package :asdf) #.(upgrade-asdf) #.(load-system :asdf-dependency-grovel))" --quit No error.
If that still fails, rather than the asdf plumbing itself, can you identify if the dependency instrumentation is still working on the latest SBCL?
How would I determine if the dependency instrumentation is working? It is not working in the sense that the known dependencies are not detected -- do you mean something else?
See if fine-grain-instrumented-load works with the expected side-effects, emitting the suitable signal-user, signal-provider, and other signal-* events. At this point, you have to read the source code. I don't believe anyone is left to help you. But if you have specific questions, I can read the source code too and maybe remember more context. (NB: I didn't write that code, but I oversaw an intern who used it, and tweaked it a little bit to package it better.)
Okay, there is a warning about an internal SB-something function -- I'll look at whether the relevant code can be updated.
Again, good luck, and happy holidays! —♯ƒ • François-René Rideau • Co-Founder and President, MuKn.io “If all values are relative, then cannibalism is a matter of taste.” — Leo Strauss
