#   error <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.
