1225736 - Turn on MDNS service on Linux

Status: NEW

(Core :: Networking, defect, P5)

Description

[Shih-Chiang Chien [:schien] (UTC+8) (use ni? plz)]

Need to provide an implementation of MDNS service on Linux to support Presentation API. I plan to integrate mDNSResponder into m-c.

The common MDNS library available on Linux is Avahi. Avahi has a dns_sd.h compliant library (libavahi-compat-libdns_sd) but is no longer maintained. Therefore we need to use Avahi client library directly but not reuse the current mDNSResponder implementation.

remove myself from assignee since I'm not actively working on it at this moment.

WIP, early-stage implementation of Avahi operator.

However, this encounters the following link error:
  ../../build/unix/gold/ld: error: Unified_cpp_dns_mdns_libmdns0.o: requires dynamic R_X86_64_PC32 reloc against 'avahi_service_browser_new' which may overflow at runtime; recompile with -fPIC
  ../../build/unix/gold/ld: error: Unified_cpp_dns_mdns_libmdns0.o: requires dynamic R_X86_64_PC32 reloc against 'avahi_client_errno' which may overflow at runtime; recompile with -fPIC
  ../../build/unix/gold/ld: error: Unified_cpp_dns_mdns_libmdns0.o: requires dynamic R_X86_64_PC32 reloc against 'avahi_threaded_poll_stop' which may overflow at runtime; recompile with -fPIC

I once made it work, but it just doesn't work anymore. Currently I have no idea how to solve this.

I'm not actively handling this issue, and it is okay if anyone wanna take this bug.
