[Pdns-dev] pdns IPv6 compilation failure on OSX (svn head)

[Justin Clift]

Hi guys,

Just tried to compile pdns auth server from svn head on OSX 10.7,
but it's barfing with IPv6 stuff:

Configuration was done using:

  ./configure --prefix=/tmp/foo --with-modules=gsqlite3 --with-lua --with-sqlite3 --with-sqlite=/usr/local

Those defines themselves do seem to be on OSX:

  $ egrep -r "IPV6_RECVPKTINFO|IPV6_PKTINFO|IPV6_PKTINFO" /usr/include/*
  /usr/include/netinet6/in6.h: *   IPV6_PKTINFO
  /usr/include/netinet6/in6.h:#define IPV6_PKTINFO        IPV6_2292PKTINFO
  /usr/include/netinet6/in6.h:#define IPV6_RECVPKTINFO	61 /* bool; recv if, dst addr 
  /usr/include/netinet6/in6.h:#define IPV6_PKTINFO        IPV6_3542PKTINFO

Tried adding "#include <netinet/in.h>" to pdns/nameserver.cc, but that
make no difference. :(

Guessing it's a scoping problem of some sort?  Anyone have suggestions
for a quick fix to test with? (note that I'm not a c++ guy at all)

Regards and best wishes,
