Hello,

I am trying to write an asdf system definition that is dependent upon
other asdf systems being loaded.  The following works but I am wondering
if there isn't a better way of doing this.  I thought of using the #-
reader macro to evaluate the two asdf forms based on items in *features*
or maybe wrapping them in an eval-when.  I also thought that maybe the
:system keyword was what I needed but my understanding there is seriously
lacking.


(asdf:oos 'asdf:load-op :clsql)
(asdf:oos 'asdf:load-op :clsql-postgresql)

(defsystem "camc"
	:serial t
	:components ((:file "packages")
		     (:file "data-layer")
		     (:file "stemmer")))

Even though what I have works, it doesn't say that camc depends on clsql
and clsql-postgresql being already loaded.  Any help there will be
appreciated.

Thanks,

--dennis

ps.  I'm using sbcl 0.9.2 and its included asdf under Ubuntu Linux 5.10.
clsql was downloaded from b9.com.

How about something like:

  (defsystem camc
    :components
    ((:file "packages")
     (:file "data-layer" :depends-on "packages")
     (:file "stemmer"    :depends-on "packages"))
    :depends-on (:clsql :clsql-postgresql))

Thanks Peter, that has got to be one of the gentlest applications of the
cluestick in the history of Usenet. :)

Of course, that is exactly what I was looking for but couldn't find in
the manual.  I even looked at the "defsystem grammar" page but I never
recognized :depends-on.

Thanks for your help.
