Compilation Error - Missing 'fabricIndex' in ChipDeviceEvent

[sanjaykishor]

I am encountering a compilation error while building the CHIP (Connected Home over IP) SDK for an ARM-based Linux target (specifically, arm-poky-linux-gnueabi). The error occurs during the compilation of ../../src/app/FailSafeContext.cpp. The compiler reports that an unnamed union within chip::DeviceLayer::ChipDeviceEvent does not have a non-static data member named fabricIndex.

Error Message:

Any insights or guidance on how to resolve this issue for the arm-poky-linux-gnueabi target would be greatly appreciated.
