iptables fails to compile if IPv6 is not selected. Instead of adding this dependency, this patch modifies iptables to compile ip6tables only when IPv6 is enabled in buildroot.
Created attachment 197 [details] make use of new --enable-ipv6 flag in iptables.mk
Created attachment 199 [details] add --enable-ipv6 flag to iptables source
It looks like a buildroot bug. Please set "Product:" field correctly.
Is this patch sent upstream? Could you please provide a pointer to the mailing list archive / bugtracker ID? Other than that it looks fine.
I just filed a bugreport here: http://bugzilla.netfilter.org/show_bug.cgi?id=588
Created attachment 201 [details] add --enable-ipv6 flag to iptables source (updated for iptables version in BR trunk)
