<cstddef> tried including <stddef.h> but didn't find libc++'s <stddef.h> header. This usually means that your header search paths are not configured properly. The header search paths should contain the C++ Standard Library headers before any C Standard Library, and you are probably using compiler flags that make that not be the case.

no member named 'nullptr_t' in the global namespace

use of undeclared identifier 'nullptr_t'; did you mean 'nullptr'?

template argument for template type parameter must be a type
