From 070e9ad8fe6380be3fe19924cd50619e540382d0 Mon Sep 17 00:00:00 2001 From: Jan Engelhardt Date: Sun, 2 Dec 2012 19:09:38 +0100 Subject: [PATCH] build: resolve link failure for ip6t_NETMAP Link stage of libip6t_NETMAP failed since recently. CCLD libip6t_NETMAP.so /usr/lib64/gcc/x86_64-suse-linux/4.7/../../../../x86_64-suse-linux/bin/ld: cannot find -lip6tc libip6t_NETMAP.c uses the "ipv6_prefix_length" function from libip6tc.so; "-lip6tc" is used in the Makefile, but, the directory to it is not specified. Why does the link succeed for some people? Because /usr/lib(64)/libip6tc.so satisfies -lip6tc, but not all environments, especially those without iptables development files, have that file, hence this link error can happen.
