ModemManager: symbol lookup error: ModemManager: undefined symbol: mm_kernel_event_properties_get_type

[Jan Graczyk]

Hello Aleksander,

I have used ./configure --with-qmi=yes than make and make install and I have run ModemManager with a command ModemManager --debug. Am I missing any other option in ./configure? Thank you for your help.

Since ModemManager is using by default baud rate set to 57600 I have decided to move to the latest version of ModemManager (1.7.0) since there is a possibility to set udev rule for baud rate ENV{ID_MM_TTY_BAUDRATE}="115200". However after rebuilding ModemManager version 1.7.0 for ARM architecture and running it on my development board I have got the following error:

I would like to take advantage of ModemManager version 1.7.0 but unfortunately I am getting the above error while running it.

Looks like you didn't install the newly compiled version properly.
You're running the ModemManager daemon from git master, and looks like it's linking to "libmm-glib" from an older version.

How did you configure ModemManager to build, and how are you running it?
