I was trying to compile the modem drivers of Quectel EM05-G as described in the documentation for Linux PC, but i end up with these error.
any suggestions ?

Use standard Linux drivers.
Thank you for the response.
Can you elaborate what you mean by standard Linux drivers? do you mean qmi_wan and usb to serial driver?
When I plug in modem eval board to Ubuntu PC (5.4.0-150-generic #167~18.04.1-Ubuntu) I see following dmessages, basically i was expecting some kind of ttyACMx dev nodes.

Basically, my idea to use libqmi-glib to interact with modem(for getting modem stats/diagnostics instead of AT commands) and use qmi interface for data connection.

Standard means cdc_mbim or qmi_wwan or cdc_ether for data and option for serial.
Note that this particular submodel is not supported in the kernel you use, you need to update it or add the IDs manually using new_id.
Please use proper formatting for code.
thanks, will check on latest kernel.
