Hi,
I'm trying to run geoclue 0.12 just on the system bus, but non of the
examples work. Has anybody configured it with "--enable-system-bus" and
was able to run any of the examples? Do I still have to provide a
session bus?
e.g.
/geoclue-0.12.0/example/.libs]$ ./position-example Gypsy
Using provider 'Gypsy'
Failed to open connection to bus: dbus-launch *failed to autolaunch D-Bus
session*: Autolaunch error: X11 initialization failed.
** (process:1142): CRITICAL **: dbus_g_proxy_add_signal: assertion
`DBUS_IS_G_PROXY (proxy)' failed
** (process:1142): CRITICAL **: dbus_g_proxy_connect_signal: assertion
`DBUS_IS_G_PROXY (proxy)' failed
** (process:1142): CRITICAL **: dbus_g_proxy_call: assertion `DBUS_IS_G_PROXY
(proxy)' failed
Latitude and longitude not available.
I also tried the master-pos-example.
./master-pos-example
(process:1159): GLib-GObject-WARNING **: invalid (NULL) pointer instance
(process:1159): GLib-GObject-CRITICAL **: g_signal_connect_data:
assertion `G_TYPE_CHECK_INSTANCE (instance)' failed
(process:1159): GLib-GObject-CRITICAL **: g_type_instance_get_private:
assertion `instance != NULL && instance->g_class != NULL' failed
Segmentation fault
Geoclue service files are located in share/dbus-1/services. Gypsy also
runs on the system bus (with working gypsy examples), but its service
files are in system-services, including a "User=root" line. So I moved
the service files to system-services and also added a user.
Futhermore I put a Geoclue.conf file in etc/dbus-1/system.d:
...
<busconfig>
<policy user="root">
<allow own="org.freedesktop.Geoclue.Master"/>
<allow own="org.freedesktop.Geoclue.Providers.Gypsy"/>
<allow own="org.freedesktop.Geoclue.Providers.Gpsd"/>
</policy>
<policy context="default">
<allow send_destination="org.freedesktop.Geoclue.Master"/>
<allow send_destination="org.freedesktop.Geoclue.Providers.Gypsy"/>
<allow send_destination="org.freedesktop.Geoclue.Providers.Gpsd"/>
</policy>
</busconfig>
...
The --enable-system-bus option creates a macro in config.h
#define GEOCLUE_DBUS_BUS DBUS_BUS_SYSTEM
But in geoclue-provider.c => constructor () => connection =
dbus_g_bus_get (DBUS_BUS_SESSION, &error);
DBUS_BUS_SESSION is hard coded (instead of GEOCLUE_DBUS_BUS ?).
Besides, in master.c => gc_master_init()
g_warning ("Could not get %s: %s", GEOCLUE_DBUS_BUS, error->message);
the first %s leads to a Segmentation fault.
With these changes the necessary providers start on its own (master,
gypsy, gpsd) and also gypsy.
