OK, it looks like loading dbus.el is where it fails when following
the instructions given in this URL:
http://cygwin.com/ml/cygwin/2010-08/msg00892.html
I guess this step is not necessary but emacs shouldn't hang.
Here's the steps I followed:
$ eval `dbus-launch --auto-syntax`
$ echo $DBUS_SESSION_BUS_ADDRESS
unix:path=/tmp/dbus-dlr0QTU52y,guid=2ed2e65c8040f348d71319f94cc36ca0
$ xterm& # This gives me a new xterm with "DBUS_SESSION_BUS_ADDRESS"
set.
In new xterm:
$ dbus-monitor
signal sender=org.freedesktop.DBus -> dest=:1.0 serial=2 path=/org/freedesktop/DBus; interface=org.freedesktop.DBus; member=NameAcquired
string ":1.0"
method call sender=:1.0 -> dest=org.freedesktop.DBus serial=3 path=/org/freedesktop/DBus; interface=org.freedesktop.DBus; member=AddMatch
string "type='method_call'"
method call sender=:1.0 -> dest=org.freedesktop.DBus serial=4 path=/org/freedesktop/DBus; interface=org.freedesktop.DBus; member=AddMatch
string "type='method_return'"
method call sender=:1.0 -> dest=org.freedesktop.DBus serial=5 path=/org/freedesktop/DBus; interface=org.freedesktop.DBus; member=AddMatch
string "type='error'"
In first xterm:
$ emacs&
In that emacs:
(dbus-get-unique-name :session)
":1.0"
load-file /usr/share/emacs/23.2/lisp/net/dbus.el.gz
Hangs emacs after the "done" message...
Likely, you didn't start the system bus (the scenario is only about the
session bus).
I've committed a patch to the Emacs-23 branch which ought to handle this
situation:
2010-10-08 Michael Albinus<michael.albinus@gmx.de>
* dbusbind.c (xd_get_dispatch_status): Return a Lisp_Object.
(xd_pending_messages): Catch xd_get_dispatch_status calls.
I don't know, whether this has reached already in Cygwin's Emacs
package. However, if you are using D-Bus you shall ensure that both the
system and session buses are running.
