Hi,
I'm new to Arch, but I have used Ubuntu so far.
My Task: setup arch with ntpd and a DCF clock at /dev/ttyUSB0 as stratum 0 input.
Problem: ntpd does not recognize the hardware specific format in /etc/ntp.conf
# Expert mouseCLOCK USB II
server 127.127.8.0 mode 19
fudge 127.127.8.0 refid DCF
It seems in ubuntu ntpd is compiled with --enable-parse-clocks, but the binary packets from arch are not ?
a) How can I verify this? Which options are used to compile the binary arch ntpd package?
b) What is the preferred solution in arch? Download ntpd from source? From ntp.org? From arch package sever? Compile it manually?
Thanks very much

a) You can read the PKGBUILD for any package: https://projects.archlinux.org/svntogit … es/ntp#n32
b) Build it with that option enabled: https://wiki.archlinux.org/index.php/Abs

I have no idea about your ntp problem. But you can retrieve the source of a package with the ABS. You can also install yaourt from the AUR and simply say: yaourt -G ntp
You end up in a directory where you say makepkg. If you want to modify the build options just edit the PKGBUID. It is mostly a standard shell script. It is much easier to understand than .deb or .rpm packages; the only things you have to know is bash scripting.

Hi, thanks for both answers!
PKGBUILD confirms my problem with ntp package: many important configure options are missing --enable-NMEA --enable-GPSD --enable-SHM --enable-LOCAL-CLOCK --enable-parse-clocks
Abs sound nice - I will do some reading and testing.
Thanks very much!
