where the headers are stable. There are still lots of incompatible changes
made and the libc headers have to follow.
Also, make sure you have a suitably recent kernel. As of the 970401
snapshot, according to Philip Blundell <Philip.Blundell@pobox.com>, the
required kernel version is at least 2.1.30.
{PB} The 2.1 release of GNU libc aims to comply with the current versions of
all the relevant standards. The IPv6 support libraries for older Linux
systems used a different naming convention and so code written to work with
them may need to be modified. If the standards make incompatible changes in
the future then the libc may need to change again.
IPv6 will not work with a 2.0.x kernel. When kernel 2.2 is released it
should contain all the necessary support; until then you should use the
latest 2.1.x release you can find. As of 98/11/26 the currently recommended
kernel for IPv6 is 2.1.129.
Also, as of the 2.1 release the IPv6 API provided by GNU libc is not
100% complete. In particular the getipnodebyname and getipnodebyaddr
functions are not implemented.
