Hi, In ubuntu we applied the upstream's fix at https://github.com/radvd-project/radvd/pull/196. I adapted it to a pair of patches that I attach here for fixing this FTBFS.
I am sending this for your consideration, and I hope it helps. Best, Miriam -- [image: Canonical-20th-anniversary] Miriam España Acebal Software Engineer II - Ubuntu Public Cloud/Server Email: miriam.esp...@canonical.com Location: Spain (GMT+2) canonical.com ubuntu.com

Clang 16 makes -Wimplicit-function-declaration error by default (and it's planned that GCC 14 will do the same) so we need to fix the real problem. This is papering over it. 2. It's not true that there's nothing we can do about it. Fix in a follow-up commit.
