Hi, I just made NIO asdf-installable. The only change I made to what's in the current code was: Index: nio.asd =================================================================== --- nio.asd (revision 3) +++ nio.asd (working copy) @@ -9,5 +9,5 @@ (:file "async-socket" :depends-on ("async-fd")) ) - :depends-on (:cffi)) + :depends-on (:cffi :event-notification)) Hope that looks ok to you. If not, just let me know and I'll change it. Cheers, Bill. -- William Bland: http://www.abstractnonsense.org/ Lisp documentation: http://www.lispdoc.com/
