From 3b50d9029809b60a5081d90c282aa04d438d3ea1 Mon Sep 17 00:00:00 2001 From: WANG Cong Date: Tue, 6 Jan 2015 15:45:31 -0800 Subject: ipv6: fix redefinition of in6_pktinfo and ip6_mtuinfo MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Both netinet/in.h and linux/ipv6.h define these two structs, if we include both of them, we got: /usr/include/linux/ipv6.h:19:8: error: redefinition of ‘struct in6_pktinfo’ struct in6_pktinfo { ^ In file included from /usr/include/arpa/inet.h:22:0, from txtimestamp.c:33: /usr/include/netinet/in.h:524:8: note: originally defined here struct in6_pktinfo ^ In file included from txtimestamp.c:40:0: /usr/include/linux/ipv6.h:24:8: error: redefinition of ‘struct ip6_mtuinfo’ struct ip6_mtuinfo { ^ In file included from /usr/include/arpa/inet.h:22:0, from txtimestamp.c:33: /usr/include/netinet/in.h:531:8: note: originally defined here struct ip6_mtuinfo ^ So similarly to what we did for in6_addr, we need to sync with libc header on their definitions.
