[Claudio Lorini]

Hello everybody,

i'm trying to rebuild machinekit from scratches on a Zedboard (http://zedboard.org/product/zedboard)  platform 

from a pristine Debian image:

Distributor ID: Debian
Description: Debian GNU/Linux 7.8 (wheezy)
Release: 7.8
Codename: wheezy

with a 3.8.0  kernel: 

Linux zedebian 3.8.0-xilinx #8 SMP PREEMPT Thu Jan 29 15:03:04 CET 2015 armv7l GNU/Linux

xenomai patched:

I-pipe: head domain Xenomai registered.
Xenomai: hal/arm started.
Xenomai: scheduling class idle registered.
Xenomai: scheduling class rt registered.
Xenomai: real-time nucleus v2.6.4 (Jumpin' Out) loaded.
Xenomai: debug mode enabled.
Xenomai: starting native API services.
Xenomai: starting POSIX services.
Xenomai: starting RTDM services.

i added the repositories to the sources list:

root@zedebian:~/machinekit# cat /etc/apt/sources.list.d/*
deb http://deb.dovetail-automata.com wheezy main
deb http://ftp.it.debian.org/debian wheezy-backports main

apt-get update seems to complete without errors:

..shouldn't they come from http://deb.dovetail-automata.com?

I'know i can build from sources, i've already tried with a Linaro(Ubuntu) environment but got stuck later on in 

the build process so i tried a more traveled path...

any suggestion where to get the pre-built packages?

These packages are not in the standard Debian Wheezy repositories. You
can find them in John's repository. Take a look at
http://www.machinekit.io/docs/packages-debian/

You may be able to reuse packages for another platform (BeagleBone). If
not you need to rebuild the necessary packages.

...John's repository is deb.dovetail.automata.com? 

maybe yesterday i was experiencing the same connection problem signaled today...

I'll retry as soon as the repository is up again

thank you, C.

[Claudio Lorini]

...ok, I think I found the problem i was having, I'll put it here if anyone will experience the same in the future:

http://deb.dovetail-automata.com contains only 'armhf' (arm with hardware floating-point) packages and I 

have installed from scratch a Debian image using 'armel' packages, so apt-get was looking for 'armel' packages. 

I'll try to restart from a 'armhf' netinstall to see what happens, but i think it'll work... 

C.

[Claudio Lorini]

confirmed.

works like charm!
