.... this kind of error came

kuksa-databroker kuksa.val

need suggestion on it how to resolve

This error was thrown by linker, when you start a cross-compilation but not specify the linker for that. To solve this error, check this file:

~/.cargo/config.toml

and then add the specific linker for the target that you are trying to build for. For example:

[target.armv7-unknown-linux-gnueabihf]
linker = "arm-linux-gnueabihf-gcc"
