The test in configure is:
dnl>
dnl> check for ip6 address used by sFlow...
dnl>
AC_MSG_CHECKING(if in6_addr is defined)
AC_CACHE_VAL(ac_cv_in6_addr_has_ea,
LBL_SAVE_CFLAGS="$CFLAGS"
CFLAGS="$CFLAGS $V_INCLS"
AC_TRY_COMPILE([
# include <sys/types.h>
#include <netinet/in_systm.h>
# include <sys/socket.h>
# include <netinet/ip.h>
# include <netinet/in.h>],
[struct in6_addr tmp;],
ac_cv_in6_addr_has_ea=yes,
ac_cv_in6_addr_has_ea=no)
CFLAGS="$LBL_SAVE_CFLAGS")
AC_MSG_RESULT($ac_cv_in6_addr_has_ea)
if test $ac_cv_in6_addr_has_ea = yes ; then
AC_DEFINE(HAVE_IN6_ADDR)
fi
I.e. can it compile "struct in6_addr tmp;" from that list of includes.
It looks like it's finding it in netinet6/in6.h...
Which must be included from something in the sflow program, but not in the test
program, so it's not setting HAVE_IN6_ADDR. Without that set, it's duplicating the
struct define.
I don't have access to a FreeBSD system - I need you to figure out where in the
FreeBSD includes it's including netinet6/in6.h
Then we can update the test...
