(usagi-users 02166) Bug: Fails to build - anycast and mobility

[Lionel Elie Mamane <lionel@xxxxxxxxx>]

Hi,

Kernel version: 2.4.20
Usagi patch used: ftp://ftp.linux-ipv6.org/pub/usagi/snap/split/usagi-linux24-s20030203-2.4.20.diff.bz2
Usagi version: Snapshot 3 Feb 2003

The patched kernel fails to build with a particular
configuration. Looks to me like Mobility Support depends on Anycast
Support, but this is not in the configuration system, neither
documented in the help texts. Indeed, adding anycast support in the
kernel solves the problem.

Here the error message:
