Bug 277366 – net-firewall/iptables-1.4.3.2 fails to build against uclibc with disabled IPv6 support

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Christian Affolter 2009-07-10 22:39:35 UTC]

net-firewall/iptables-1.4.3.2 fails to build against sys-libs/uclibc-0.9.30.1-r1  if it lacks IPv6 support:

ip6tables_static-ip6tables.o: In function `print_firewall':
ip6tables.c:(.text+0x7dc): undefined reference to `in6addr_any'
ip6tables.c:(.text+0x8d5): undefined reference to `in6addr_any'
collect2: ld returned 1 exit status
make[2]: *** [ip6tables-static] Error 1


Please find attached a patch against net-firewall/iptables-1.4.3.2 which provides an ipv6 USE-flag. If the flag isn't set, iptables will be compiled with '--disable-ipv6' and no ip6tables* related files will be merged.

Patch against iptables-1.4.3.2.ebuild with ipv6 enable/disable functionality.

this patch is a regression.  declaring flags in a local var rather than passing straight to econf is wrong.

presumably the only econf change needed is to add a line like:
$(use_enable ipv6)

Ok, I modified the ebuild and created a new patch, according to http://devmanual.gentoo.org/ebuild-writing/functions/src_compile/configuring/index.html
