Recently, attempting to build these packages in a 'pbuilder' chroot showed several problems. First, some dependencies were missing (e.g., rtai-modules-2.6.12-magma for emc2, and python2.4-tk and emc2 for emc2-axis). Additionally, the linux-image-2.6.12-magma package won't install in the pbuilder chroot unless the hook [D99kernel-img.conf] is used, and the actual running kernel must also be linux-image-2.6.12-magma. Patches to fix any of these problems are happily accepted.

These instructions are mostly of historical interest. They describe building emc 2.0.x on the old version of ubuntu.

Rebuilding emc2 and emc2-axis debs

 $ sudo apt-get install emc2
[reboot to the 2.6.12-magma kernel if you're not running it already]
 $ sudo apt-get build-dep emc2 emc2-axis
 $ fakeroot apt-get -b source emc2 emc2-axis

Rebuilding emc2 and emc2-axis debs in pbuilder

Recently, attempting to build these packages in a 'pbuilder' chroot showed several problems.

Create the chroot like this (split across two lines for clarity):

 $ sudo pbuilder create --mirror http://us.archive.ubuntu.com/ubuntu --distribution breezy \
--othermirror "deb http://www.linuxcnc.org/emc2/ breezy emc2"

Get the emc2 and emc2-axis source like this:

 $ apt-get source emc2 emc2-axis

Run pbuilder:

 $  sudo pbuilder build --hookdir /home/jepler/pbuild-hook/ emc2_2.0.0.dsc 
(you'll need to modify the --hookdir value to match your system)

Rebuilding linux-image-2.6.12-magma and rtai-modules-2.6.12-magma

From: Chris Radek <chris@timeguy.com>
Subject: instructions for kernel/rtai build

I started these instructions a while back; I think they still reflect what I did to build kernel and rtai. I have no idea whether they're the "right" debian way. I think any hacked scripts make it into the src debs, but I haven't tested extensively. Especially suspicious are changes I've made to /usr/share/kernel-package, but those are mostly to silence scary warnings during kernel updates that I determined were not necessary (because I didn't change the list of modules). For the make-kpkg invocations --revision might not be necessary (I think it can get it from the changelog).

It's impossible to build a kernel right the first time. It's worth your time to install and configure ccache right now.

install and untar linux-source, patch it as required install and untar rtai-source (/usr/src/modules/rtai-3.3)

set in your environment:

 export CC=gcc-3.4
 export CXX=g++-3.4
 export CPP='gcc-3.4 -E'
 export CXXCPP='g++-3.4 -E'
 export MAKEFLAGS='CC=gcc-3.4 CXX=g++-3.4'
 export CONCURRENCY_LEVEL=3

check /etc/kernel-pkg.conf

use dch to edit /usr/share/kernel-package/changelog if necessary

check /usr/share/kernel-package/image.[post|pre]inst

 cd /usr/src/linux-source-2.6.12-magma
 cp /boot/config-2.6.12-magma .config
edit EXTRAVERSION in the Makefile
 make oldconfig
 make-kpkg clean
 make-kpkg --initrd --revision=xxxxx --stem=linux binary

install the resulting linux-headers package; rtai modules are built using it. this is important because we want users to be able to build realtime modules (emc) without requiring the full kernel source.

 cd /usr/src/modules/rtai-3.3
use dch to edit debian/changelog if necessary
 cp /usr/realtime-2.6.12-magma/share/rtai/config-rtai-3.3 .rtai_config
 make clean
 cd /usr/src/linux-headers-2.6.12-magma
 make-kpkg --initrd --revision=xxxxx --stem=linux modules_image

Preparing pbuilder on hardy

 $ sudo pbuilder --create --othermirror 'deb http://linuxcnc.org/hardy hardy base emc2.2' --components "main universe"
