    Welcome to Stack Overflow. Please post your full `g++` command and the full output from it as text, not as an image, so it's easier for people to copy it or search for it. I think you should also work on simplifying your code and provide it as a [mcve] so that others can easily see the error happening on their own systems. – David Grayson May 15 '22 at 18:39
  • You need to enable AVX512 when compiling. Related question: https://stackoverflow.com/questions/54654290/error-inlining-failed-to-call-always-inline – chtz May 15 '22 at 18:58
