From 20db952fc211b3444d83049f2d127da4f3ca6989 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Tue, 15 Jul 2008 13:20:01 -0400 Subject: [PATCH] We want to continue to support building nfs-utils on systems that do not have IPv6-enabled RPC libraries and headers installed, so add a ./configure switch that allows distros to disable IPv6 functionality. This patch introduces the nfs-utils autotools configuration to the library and header dependencies that will be required in subsequent patches. Later patches can then be reordered more easily if these new dependencies are added in one heap. For now, --enable-ipv6 defaults to "no", so this patch should not result in any behavioral changes to the nfs-utils build process, by default.
