Issue with Network manager configuration in yocto

Embedded Devices Linux
1

I have a digi connectcore 8m nano SOM and I am trying to make a static eth0 configuration in yocto for the same. Following the instructions as specified in the official documentation
(https://www.digi.com/resources/documentation/digidocs/embedded/dey/3.0/cc8mnano/yocto_t_configure-ne…)

I have added the following lines in my local.conf

ETH0_MODE = “static”
ETHn_STATIC_IP = “192.168.0.2” ETHn_STATIC_NETMASK = “255.255.255.0” ETHn_STATIC_GATEWAY = “192.168.0.255”

During building the image, the following error shows up

| readelf: Error: ‘/usr/lib/libjansson.so’: No such file
| configure: error: Unable to locate the Jansson library
| WARNING: exit code 1 from a shell command.

Inspecting a few files, networkmanager_%.bb depends on the jansson package (libjansson.so), however, there was no such file found in the sysroot-native.
Am I missing something here in the setup? or do I need to do some additional setup during the build?
TIA.

What version of DEY are you using?

We are using dey 3.2 currently.

try sudo apt-get install libjansson-dev

just tried adding:
ETH0_MODE = “static”
ETH0_STATIC_IP = “192.168.0.2”
ETH0_STATIC_NETMASK = “255.255.255.0”
ETH0_STATIC_GATEWAY = “192.168.0.255”
to my local.conf and the build has completed succesfully

Okay. I’ll try this and let you know.
However, this should already be a part of the source files or part of the sysroot-native. Is this because of the older dey version we are using or am I missing something here??
