How to understand some macro only found in esp-idf's components folder?

[Gfast2]

Hi ESP-IDF,

For example, I encounter compiling time problem marked with "NI_NUMERICHOST undeclared". And I "grep" all things under "~/esp/". There is some call of this macro here (see screenshot).

If I didn't found its definition there, is that means, it is not supported by esp-idf?
But why there is still some thing call this macro?

Cheers

That's correct, it's not supported.

The references to it are in the nghttp2 submodule, which is the full upstream source of nghttp2 - we clone it unmodified so it contains a lot of code which is not compiled for ESP-IDF.
