nghttp3_conv: fix call to undeclared functions 'ntohl' and 'htons' #49979

MatteoBax · 2023-09-30T12:27:16Z

I don't think it's the right method but this solves these errors when compiling for Android arm64:

I added -Wno-implicit-function-declaration option to cflags

This should be unnecessary as I believe this was already fixed upstream in v0.12.0. Our copy of nghttp3 just needs to be upgraded.

That's not a proper fix, it possibly doesn't even produce a functional build. Can you try this patch?

With this patch those problems no longer occur, but now the problems are:

Covered in #46952.

Ok. I revert the changes and applied the patch. Instead of using 'OS in "android linux"' I used 'OS=="linux" or OS=="android"' but I think it's the same thing.
