1. Problems with the :feature feature. (asdf:defsystem foo :components ((:file "pkg") (:file "code") (:file "foo" :depends-on ((:feature :frob))))) If :frob is not on *features*, load-system gives me: Error: Bad dependency (FEATURE FROB). Dependencies must be (:version <version>), (:feature <feature>), or a name If :frob is a *feature* I get a different error: Error: Error component :FROB not found, required by #<CL-SOURCE-FILE "foo" #x8B7A3E6> Did I misunderstand something? 2. Suppose I would like some code to run at compile-time / load-time to determine where the fasls should live (e.g. hypothetically, in a subdirectory named after a timestamp, or according to what patches I have loaded). How do I express this? (I'm using version 1.363) Thanks. - nick
