Modem manager dies with "undefined symbol: mm_gdbus_modem_signal_skeleton_get_type"

[Daniele Palmas]

Hello,

I cloned the project from the git repository, built master and run the binary
with root permissions.

After having properly recognized the modem, ModemManager dies with the
following message:

ModemManager_bak[6292]: <info>  [1425914691.997399]
[mm-device.c:520]mm_device_create_modem(): Creating modem with plugin
'Telit' and '6' ports
/usr/local/sbin/ModemManager_bak: symbol lookup error:
/usr/local/sbin/ModemManager_bak: undefined symbol:
mm_gdbus_modem_signal_skeleton_get_type

Any hint on what's happening?

Thanks,
Daniele
