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

[Jan Graczyk]

Hello All,

I am using Quectel UC20 mini PCIe modem on my development board and running ModemManager on it. 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:

ModemManager[1624]: <debug> [1491504870.296599] [mm-plugin-manager.c:1609] load_plugins(): [plugin manager] successfully loaded 32 plugins
ModemManager[1624]: <debug> [1491504870.304070] [main.c:106] name_acquired_cb(): Service name 'org.freedesktop.ModemManager1' was acquired

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

[1]+  Exit 127                ModemManager -debug

The only stable version of ModemManager which runs on my development board is 1.4.0. But when using that version I need to set Quectel UC20 modem baud rate to 57600 using AT+IPR=57600 command. I would like to take advantage of ModemManager version 1.7.0 but unfortunately I am getting the above error while running it.

Best Regards,
