Hi there, I have moved your question the Arm Development Studio forum. Many thanks.

Hi Thanujvashan

My 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-downloads

Hope 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-downloads
