I've done some more digging, and I have a better idea of why this is failing.
Running `(asdf:operate 'asdf:compile-bundle-op :foo)` on a `package-inferred-system` produces several `.fasl` files -- one for each sub-package instead of the usual `foo--system.fasl` file. The `cleanup-files` phase then deletes[1] any `.fasl` files which do not have a `--system.fasl` suffix. I tried working around this by manually concatenating all the `.fasl` files together using `uiop:combine-fasls` which I believe works. I also had to add a new build phase to take place after the `create-asd-file` phase to do a string replace to change dependencies back to the `foo/bar` style instead of `foo-bar`. I still believe the build system should handle `package-inferred-system` style CL packages properly so that maintainers don't have to do this kind of tweaking for every package (the number of which I believe will steadily increase). I'm trying to confirm that this whole things works, but I believe I may be hitting another bug with CL being able to find dependencies. It seems as though even if the dependenices are listed in the generated `.asd` file, and my Guix SBCL can find that `.asd` and attempt to load its system, SBCL cannot find the dependencies. I'm trying to determine why this might be, but it's currently blocking me from proposing a patch which adds 44 CL packages. My current theory is that we perform a `setf` on the `*source-registry-parameter*` variable, but the ASDF manual specifically, and strongly, says[2] that this is meant to be a read-only variable. Maybe this is not working as intended? I'm also going through some steps to establish a clean-room to make sure it's nothing with my setup. If anyone feels they can point me in helpful directions, that would be very much appreciated :) [1] - http://git.savannah.gnu.org/cgit/guix.git/tree/guix/build/asdf-build-system.scm#n193 [2] - https://www.common-lisp.net/project/asdf/asdf.html#g_t_002asource_002dregistry_002dparameter_002a-variable -- Katherine
