I'm stuck. So I would appreciate any pointers where to learn
more on the topic or even reading success stories and how to do
it / repeat it. TIA!
Although my problem is with compiling usr.sbin/ntp/ntpd source I
do speak about the other steps, too. This could result in a
record for later reference just in case there's something simple
I've missed (which is really easy:).
Trying to use a "Conrad parallel port radio clock" (refclock type
#35 as I have read in /usr/share/doc/ntp/{refclock,driver35}.htm)
I added the following options to my kernel config file:
--- sys/i386/conf/STEIN 2001/01/26 16:09:36 1.2
+++ sys/i386/conf/STEIN 2001/02/02 17:50:04

After building and installing the kernel dmesg(8) output proves
the hardware gets detected and is working. I don't care much
that I added too many options or at least more than I had to. :>

Doing another
cd /dev && sh MAKEDEV pcfclock0
I can even 'cat /dev/pcfclock0' (no matter how funny the output
looks). And I noticed /var/log/messages to grow:

`uname -sr` tells me "FreeBSD 4.2-STABLE", last cvsup + cvs up
was done on January 24th. Although this shouldn't matter since
there's no problem in this stage yet.
Next step was to setup ntpd(8) to use this source. So I tried
something as simple as the following /etc/ntp.conf:
# ----- /etc/ntp.conf ---------------------------------
server 127.127.35.0
driftfile /etc/ntp.drift
logfile /var/log/ntp
logconfig =all
statsdir /tmp/
filegen loopstats file loopstats type day enable
filegen clockstats file clockstats type day enable
# ----- E O F -----------------------------------------
So let's start the daemon without rebooting:
# grep -C ntpd /etc/rc.*
# grep ntpd /etc/defaults/rc.conf /etc/rc.conf
# ntpd -p /var/run/ntpd.pid
This is where I find myself welcomed with a message stating
...
refclock_newpeer: clock type 35 invalid
configuration of 127.127.35.0 failed
...
Looking at the "strings `which ntpd`" output I notice there's no
"pcfclock" word in the executable. There's no "pcf" at all in
there. After some digging around I applied the following
modification:
# cvs diff usr.sbin/ntp

This results in compilation errors. :( Not only did I do "make
clean; make depend; make obj; make all" in the usr.sbin/ntp
directory, I even went back to a "make buildworld" and after some
nine hours got the same error as in the above short "make all"

Since I understand that the contrib/ntp dir is a source container
only while usr.sbin/ntp is the actual working area, fail to see
any other reference to "PCF" in the tree, and haven't seen any
knobs in the Makefile - my only possible conclusion is that
modifying the config.h file really is the thing to do when adding
new sources. What did I miss? The "#define REFCLOCK 1" setting
already is in config.h. Do I have to run ./configure anew? If
so, where do I do it? In the contrib dir? And do I need tools
FreeBSD doesn't have by default? And why do I fail to see the
configure options FreeBSD's usr.sbin/ntp/config.h file was
generated with? I'm really puzzled ...
So where do I have to enable additional sources / refclocks for
compiling them into ntpd?
