undefined symbol: mm_gdbus_modem_voice_complete_transfer

[RealTehreal]

Hey, thanks again for all your effords.

I got it build and installed using the readme:
https://github.com/enzingerm/ModemManager/tree/xmm7360/plugins/xmm7360.

I load the driver as described here:
https://github.com/xmm7360/xmm7360-pci/

When I now try sudo ModemManager --debug I get:
ModemManager: symbol lookup error: ModemManager: undefined symbol: mm_gdbus_modem_voice_complete_transfer
I'm fine with helping debugging it. Just tell me what to do.

Thanks for trying! Which prefix did you specify during compiling? A user at the ModemManager mailing list had a similar problem (see [0]). Maybe it worked for me as I specified --prefix=/usr. And maybe it doesn't work for you as your ModemManager is dynamically linked to an older/newer variant of libmm-glib.so. Maybe you could try prefixing your command with LD_LIBRARY_PATH=/usr/local/lib as suggested in the mailing list (provided you used no custom prefix or used /usr/local explicitly.
