The file is backend/openmcl.lisp. I don't think this can work reliably. It seems to work, but I don't think Common Lisp guarantees it.<br>
<br>
The code is<br>
<br>
(eval-when (:compile-toplevel :load-toplevel :execute)<br>
(when (find-class 'ccl::ip6-socket-address nil)<br>
(pushnew :ccl-1.11-sockets *features*)))<br>
<br>
I think a much more robust solution would be for this to go in an earlier file that is guaranteed to be loaded before backend/openmcl.lisp is compiled.<br>
<br>
Can one of the developers review this?<br>
<br>
Also, any word on when this will propagate to Quicklisp?<br>
<br>
Thanks,<br>
