Hi folks, Recently, in order to increase the modularity of our project's ASDF dependencies, I introduced a sub-class of MODULE called GROUP. We wanted to keep all of our main .lisp files in the toplevel, so the purpose of the class is simply to define a method for the COMPONENT-RELATIVE_PATHNAME generic function. The problem that I'm experiencing is that the dependencies at the MODULE (GROUP) level don't appear to be established (i.e. modifying one group does not cause its dependents to be re-compiled). Here is a snippet of the code: ;; a GROUP is an ASDF component whose files are located in its parent ;; component's directory. (defclass group (module) ()) (defmethod component-relative-pathname ((component group)) (make-pathname :host (pathname-host (component-pathname (component-parent component))))) (defsystem :foo :components ((:file "packages") (:group "x" :depends-on ("packages") :components ((:file "a") (:file "b" :depends-on ("a")) (:file "c" :depends-on ("b")) (:file "d" :depends-on ("a" "b")))) (:group "y" :depends-on ("packages" "x"") :serial t :components (...)))) Any thoughts? Regards, - Scott Bell
