Hello forumees.
I am running as root on an OrangePI Zero+ which uses a H2 processor running a CL version of arrmbian  3.4.113 which works fine.

I have recently obtained a SimCom SIM7600CE GSM/GPS module which has only a USB interface. I tracked down drivers for it but the Linux version must be compiled to a module which I have managed (with a number of warnings) after a couple of hiccups. Now trying to install the compiled module is resulting in error messages. I think the problem is compatability with armbian which is beyond my expertise, so I am asking for help.

Below is the CL dialog of my attempts to install the module.

I have attached the source of the module, the Makefile and a full log of the 'make all'

 

Makefile GobiSerial.c make.log

If it's really a Gobi, then consider libqmi/libmbim and modemmanger - they're in the upstream repos... and there's a PPA as well...

 

https://launchpad.net/~aleksander-m/+archive/ubuntu/modemmanager-bionic

 

Might work out of the box there - modemmanager is pretty cool, abstracts out a lot of the lower level stuff...

 

That should get Gobi working as a modem - for GNSS oriented stuff, better to go with a GPS module like the uBlox Neo-6/7/8 modules, they're great for navigation and timing stuff, and they typically will interface with UART rather than USB
