iio-sensor-proxy does nothing and just exits

[aroig]

I'm testing iio-sensor-proxy on a Thinkpad Yoga. I get the following output, and then it just exits.

$ sudo G_MESSAGES_DEBUG=all iio-sensor-proxy

It looks like the sensors are recognized, but any_sensors_left (data) returns FALSE in main(). Any clue of what is going on?

Oh, by the way, I run this with kernel 4.0.7 on arch linux.

Thanks!

Do you still need help, or you think you can figure it out? :)

It is definitely not running. I did read the logs I posted! The systemd service triggered from udev also just exits.

This message is printed from name_lost_handler, but not at the time g_bus_own_name is called, since the bulk of the debug messages I posted happen after dbus is setup.

From a quick look at the code, my guess was that any_sensors_left (data)) returned FALSE for some reason, and dbus called the handler before releasing the bus name. I could have spent more time debugging this, but I preferred to ask first!

Did you install the dbus service file in the correct location?

[aroig]

Ah! that was it! I used ./configure --prefix=/usr, and make install had put the file in /usr/etc.

Thanks a lot!
