cpu requirements for `x86intrin.h`?

Hi there I thought the minimum CPU requirements to run x86intrin.h is an intel 3th gen processor.

however when i run this code

_rdseed64_step(&temp2);

i get the following error

error: inlining failed in call to always_inline 'int _rdseed64_step(long long unsigned int*)': target specific option mismatch

_rdseed64_step (unsigned long long *__p)

I have set the flag to march=native and it only occurs when i am using my desktop, when i run on my laptop that is running a 6th gen processor it works fine.
