[slime-devel] [CMUCL] Problem: Binding socket to port 0
Hi, I try to install slime (HEAD at Thu Jun 24 12:26:02 MDT 2004) on my SGI box. I am running cmucl 18e (see the log below) and it complains about a binding to port 0. As far as I know, the problem comes from swank.lisp where we read: (defun start-server (port-file &optional (style *communication-style*) dont-close) (setup-server 0 (lambda (port) (announce-server-port port-file port)) style dont-close)) \!/ Notice the (setup-server 0 ... \!/ and: (defun setup-server (port announce-fn style dont-close) (declare (type function announce-fn)) (let* ((socket (create-socket *loopback-interface* port)) (port (local-port socket))) \!/ Notice the 'port' use on the first ligne of the let* which here is 0.\!/ ... and as far as 'create-socket' uses ext:create-inet-listener, i guess that this is the problem. here goes the log. hope this helps ----------------------< LOG >----------------------- CMU Common Lisp 18e, running on batou With core: /local/lib/cmucl/lib/lisp.core Dumped on: Thu, 2003-04-10 03:01:10+02:00 on Neptune See <http://www.cons.org/cmucl/> for support information.

Hi,
I try to install slime (HEAD at Thu Jun 24 12:26:02 MDT 2004) on my SGI box. I am running cmucl 18e (see the log below) and it complains about a binding to port 0. As far as I know, the problem comes from swank.lisp where we read:
(defun start-server (port-file &optional (style *communication-style*) dont-close) (setup-server 0 (lambda (port) (announce-server-port port-file port)) style dont-close))
\!/ Notice the (setup-server 0 ... \!/
and:
(defun setup-server (port announce-fn style dont-close) (declare (type function announce-fn)) (let* ((socket (create-socket *loopback-interface* port)) (port (local-port socket)))
\!/ Notice the 'port' use on the first ligne of the let* which here is 0.\!/
Giving zero for the port is intended to mean "use any available port." I thought that was POSIX or the like but maybe it's not portable. As a temporary workaround I suggest changing '0' to 'default-server-port'. The downside is that if you try to start a second SLIME on the same machine with `C-u M-x slime' then it won't be able to bind the listen socket. See also the thread started by Stefan Reichör just a now about a similar issue with CMUCL on FreeBSD. -Luke

I apologize, the problem was on the :host key side, not on the port 0 side. You previous assumption was right, giving port zero means "use any available poer". So now everything is good for me too. thanks a lot. c.
