Hello All,
I am trying to build ModemManager for ARM architecture. However during the compilation I have got the following problem:
/home/jgraczyk/var_som_mx6_debian/toolchain/gcc-linaro-4.9-2016.02-x86_64_arm-linux-gnueabihf/bin/../lib/gcc/arm-linux-gnueabihf/4.9.4/../../../../arm-linux-gnueabihf/bin/ld: cannot find -lgmodule-2.0

How can I resolve this problem? I appreciate your help very much.

Hello Dan,
Thank you for your response. The next question I have for you is how to cross compile ModemManager for ARM architecture. I am using ModemManager version 1.4.2 to build. Is that version stable enough to run on ARM based processor? The version of ModemManager on my target is 1.4.0 and it is working well.
Best Regards,
Jan Graczyk

The UC20 should be using QMI, not AT ports. qmi_wwan support for the
UC20 has been there since 2013. But to use it, you need to:
1) ensure qmi_wwan has been built for your kernel
2) ensure you build ModemManager with libqmi support (--with-qmi=yes)
This will solve both your problems, most likely.
