Beckhoff ethercat 64 with bit linuxcnc, How to install.

Hi.
Doing:
4. configure for debian
Terminal :cd debian
Terminal : ./configure uspace
(should run without errors)............jejejejejej

I obtain:
Package libxenomai-dev exists, but information about its source package
is not available. This most likely means that you do not have the
right deb-src lines in /etc/apt, or that you need to "apt-get update".

I dont find the repositories.

have you already tryed:

sudo apt-get update, after this
sudo apt-get upgrade

if this fails again, skip this step. And do the next step and obeye the output from the other configure step.

Yes for sure.

if this fails again, skip this step. And do the next step and obeye the output from the other configure script.

Hi
Skiping:
Terminal: ./configure uspace
All whent well

okay, that means linuxcnc is running as rip install now ?
