[Swan] Compiling on Ubuntu 16.04

[Whit Blauvelt]

Paul,

Thanks for instant response. That page refers to old versions of 3 things.
"The workaround #1 is very specific to Wheezy (libc < 2.19 and kernel <
3.12). Later distributions fixed issues #1 and #2. #3 is because libunbound
is too old."

The Ubuntu 16.04 box in question has:

  libc = 2.23-0ubuntu10 
  kernel = 4.4.0-93-generic
  libunbound2 = 1.5.8-1ubuntu1.1 

All of these are new enough, according to that page, to not be a problem.

At the bottom of that page there's an apparently unrelated section about
"Kernel 4.16 got a fix that could cause error". Make all does throw some
nonfatal errors before what I quoted before. The first does look related to
that:

In file included from /usr/src/libreswan-3.25/programs/pluto/linux-copy/linux/xfrm.h:5:0,
                 from /usr/src/libreswan-3.25/programs/pluto/kernel_netlink.c:56:
/usr/include/netinet/in.h:101:5: error: expected identifier before numeric constant
     IPPROTO_HOPOPTS = 0,   /* IPv6 Hop-by-Hop options.  */

Is it the patch for that bug, in the linked email, that's pertinent here?
The emails say that patch is already applied though. Was there a regression
in libreswan 3.25? 

Sorry if I'm being dense. But I'm not sure what that page is suggesting I
need to do. Following the Executive Summary with its Makefile.inc.local
creating, then "make deb," is not it, and fails in same way I reported
before:

...
dpkg-source: warning: unknown information field 'Rules-Requires-Root' in input data in general section of control info file
dpkg-source: error: cannot read libreswan-3.25/debian/patches/0003-update-README.nss-to-match-debian-defaults-for-IPSEC.patch: No such file or directory
