<h1>Build Environment Ubuntu 9.10 (Karmic Koala)</h1>

Despite the assertion on [[Build_Environment_Ubuntu_9.04]], I was unable to
build the basic gumstix image using the svn trunk. It seems the trunk uses
some deprecated features of gcc. I would suggest trying to change symbolic
links for gcc, g++, etc to point to version 4.1 instead of 4.4. If that works,
then all is good. As an alternative, what you can do is install an older
version of Ubuntu that is known to work in a
[http://en.wikipedia.org/wiki/Chroot chroot]. Any program that
is run in the chroot cannot "see" the real root file system, so all of the
build tools it find will be the ones installed in that chroot directory. This
HOWTO describes how to setup the build system with such a method.

<h2>Install debootstrap chroot</h2>

The first thing we need to do is install the chroot program that we'll be using.
You can install these programs with the following two commands

sudo apt-get install dchroot
sudo apt-get install debootstrap

<h2>Create a Chroot Directory for Older Distro</h2>

Now we need to create a new directory that will act as the root for the older
distribution's file system. Do this with the following command

sudo mkdir /var/chroot

<h2>Edit Configuration</h2>

We now edit the configuration file for the chroot program. The file is found
in /etc/schroot/schroot.conf, so open it with the following commands

cd /etc/schroot
sudo gedit schroot.conf

Since the build tools from the Gutsy distribution are known to work, I opted
to install that distribution in my chroot. So add the following lines to the
end of schroot.conf, replacing "YourUserName" with your actual user name

[gutsy]
description=Ubuntu 7.10 (Gutsy Gibbon)
location=/var/chroot
priority=3
users=YourUserName
groups=sbuild
root-groups=root

<h2> Install Gutsy </h2>

Now we need to install the older distribution into this chroot. Do this with
the following command

sudo debootstrap --variant=buildd --arch i386 gutsy /var/chroot/ http://old-releases.ubuntu.com/ubuntu

If you would like to use a different distribution, just change "gutsy" to
whichever distribution you want. Note you may have to use archives.ubuntu.com
if the distribution isn't that old.

<h2> Login to Gutsy </h2>

No login to the chroot-ed distribution with

sudo chroot /var/chroot

<h2> Install Dependencies </h2>

Below is a list of all the dependencies I had to install in order to get
bitbake to make the gumstix-basic-image. wget and groff weren't reported
by bitbake as required packages but I encountered build errors if they weren't
present.

apt-get install help2man
apt-get install diffstat
apt-get install texi2html
apt-get install cvs
apt-get install subversion
apt-get install bzip2
apt-get install gawk
apt-get install texinfo # makeinfo command
apt-get install wget
apt-get install groff # nroff command (item 1059)

<h2> Download Build Files </h2>

Now we can download the build environment from gumstix. First create a
directory to download them into. Note that we're still in the chroot-ed
environment so when we say "/home/YourUserName" it will actually be installed
in "/var/chroot/home/YourUserName". As always, replace "YourUserName" with
your actual user name.

mkdir /home/YourUserName
cd /home/YourUserName
mkdir gumstix
cd gumstix

Then we can download the environment from subversion

svn co https://gumstix.svn.sourceforge.net/svnroot/gumstix/trunk gumstix-oe

<h2> Make a "new" user </h2>

We can't run bitbake as root so we need to create a user in this chroot. I
suggest using the same user name that you use in your "real" system.

useradd YourUserName
passwd YourUserName

<h2> Edit extras/profile </h2>

If you installed into a directory other than ~/gumstix/gumstix-oe then you'll
need to edit a line in extras/profile to point to the right directory

gedit gumstix-oe

<h2> Setup the Environment </h2>

To setup the environment so that the bitbake install script can find everything
correctly we need to execute the profile script

. /home/YourUserName/gumstix/gumstix-oe/extras/profile
or
source /home/YourUserName/gumstix/gumstix-oe/extras/profile

<h2> Install the Included Bitbake </h2>

Now we can install bitbake with the setup script.

cd /home/YourUserName/gumstix/gumstix-oe/bitbake
./setup.py install

<h2> Create Source Code Cache </h2>

We need to create the "global" source code cache for the chroot system. Start
by creating a group called "oe"

sudo groupadd oe

Then add yourself to it

sudo usermod -a -G oe YourUserName

Then create the directory for caching source code

sudo mkdir /usr/share/sources
sudo chgrp oe /usr/share/sources
sudo chmod 0775 /usr/share/sources
sudo chmod ug+s /usr/share/sources

<h2> Login </h2>

We can't run bitbake as root so let's login

su - YourUserName

<h2> Setup Build Environment </h2>

We need to setup the build environment again by executing the profile script.

cd gumstix/gumstix-oe
. extras/profile

<h2> Edit auto.conf </h2>

If building for something older than verdex, we need to edit the auto.conf
file.

gedit conf/auto.conf

<h2> Build Basic Image </h2>

And now we're ready to build the basic image.
