I wasn't able to include the <sys/stat.h> in the IDE , i was able to override this error by adding the "/usr/include" and $PATH variables under the " project->properties-->path and symbols-> add " , but it lead to other miscellaneous errors as below , How to add system header files under this environment

This usually means that your header search paths are not configured properly.

Hi ThanujvashanMy name is Stephen and I work at Arm.Arm Compiler 6.19 (as provided in Arm DS 2022.2) is a C/C++ compiler intended for bare-metal and embedded applications.By contrast, <sys/stat.h> is POSIX. Arm Compiler 6.19 does not provide sys/stat.h, which explains why your build is failing.Are you trying to build a Linux application? If so, you need to use GCC rather than Arm Compiler 6.You can download GCC for AArch64 GNU/Linux target (aarch64-none-linux-gnu) and other variants from https://developer.arm.com/downloads/-/arm-gnu-toolchain-downloadsHope this helps,Stephen
Thanks for the answer , currently am working on baremetal applications over Neoverse N2 model , Could you confirm me if these headers will be working in linux application over N2 FVP models
Yes, GCC 12.2.Rel1 for AArch64 GNU/Linux target (aarch64-none-linux-gnu) contains <sys/stat.h>.You can download it from https://developer.arm.com/downloads/-/arm-gnu-toolchain-downloadsStephen
