Thank you for the suggestion to upgrade ASDF, Stelian.

I upgraded my builtin SBCL asdf.fasl from 3.3.4 to 3.3.4.1 (git version) with a manual replacement of fasl.

This 

- fixes my toy test case on OSX+SBCL (no more unnecessary recompile)

- does not fix osicat on OSX+SBCL

- but both osicat and toy test case work in ccl64+OSX with no ASDF fixes needed.

- but osicat works without reloading in SBCL+Linux64, again without an ASDF upgrade.

So it looks like it could be some kind of glitch in asdf or OSX SBCL (up to 1.4.9).

Hello,

Sorry if this is the wrong place to ask ...

I’m using the ‘osicat’ package ( https://common-lisp.net/project/osicat/   and  https://github.com/osicat/osicat ) in SBCL on OSX.

whenever I do ‘(asdf:load-system “osicat”) it seems to recompile the cffi-grovel-files and their dependencies.

Is this normal, or is there some way to make it behave like asdf usually does, that it recompiles only when a file has changed?

This sounds very much like a bug in ASDF that was fixed a while ago. I suggest upgrading to the latest version and retrying.
