Cross-Packaging On Debian

Debian/Emdebian already has tons of packages. But sometimes you have a need to package or repackage a piece of software yourself. The following may be helpful if a platform you build for is not the platform you build on.

Use the following command to build a package from a repository of apt:

emsource --arch armel -b memtester

If you need to install a package for target on your host:

dpkg-cross -a armel -i zlib1g-dev_1.2.3.3.dfsg-13em1_armel.deb

The command dpkg -l | grep zlib1g will show you:

ii  zlib1g-dev-armel-cross                1:1.2.3.3.dfsg-13em1

(dpkg-cross automatically converts package names and moves content under the /usr/arm-linux-gnueabi (for armel target))

You need to configure ~/.apt-cross/emsource to use emsource without privileges of root. The content of the file may look like:

workingdir: /home/akshaal/.apt-cross-working-dir

In a case you need to build a package from sources that have already been downloaded, use the following command:

dpkg-buildpackage -aarmel

Install emdebian on ARM device

Here is how I've successfully installed emdebian on my Fujitsu-Siemens Loox N560. I assume there is an already installed emdebian-tools package and cross-compilers. Next thing is to run the following commands:

cd /tmp;
mkdir grip/
sudo debootstrap --arch=arm --foreign lenny grip/ http://www.emdebian.org/grip/
cd grip/
sudo tar -czf /tmp/emdebian-grip-arm-debootstrap.tgz .

Then SD card is to be partitioned with fdisk. For example it could be:

cfdisk /dev/sdX
mkfs.ext3 /dev/sdXy

where sdX - is a device for an SD card. And sdXy is a partition that is supposed to be used for linux on the SD card. Then mount the linux partition and untar the emdebian-grip-arm-debootstrap.tgz:

mount /dev/sdXy /mnt
cd /mnt
tar zxpvf /tmp/emdebian-grip-arm-debootstrap.tgz
ln -s bin/sh init
cd /tmp
umount /mnt

Now we can boot linux from the partition. When linux has booted and a command line appeared, run the following commands step by step:

cd /debootstrap
export PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
run ./debootstrap --second-stage
dpkg --configure -a
rm /init
cd /
ln -s sbin/init init

Now it is time to reboot linux again. This time a login prompt should work. Use root login and no password. Then configure basic settings:

echo 'nameserver 1.1.1.1' > /etc/resolv.conf
echo '127.0.0.1 localhost' > /etc/hosts
echo '172.16.0.2 myhost 172.16.0.2' >> /etc/hosts
echo 'myhost' > /etc/hostname

use actual nameserver IP instead of 1.1.1.1. Reboot PDA one more time. Then configure network:

ifconfig usb0 172.16.0.1 netmask 255.255.255.0
route add default gw 172.16.0.1

Make sure network is up and running. Then upgrade your installation:

echo 'deb http://www.emdebian.org/grip/ sid main' > /etc/apt/sources.list
apt-get update
apt-get dist-upgrade
apt-get install ...whateveryoulike...

And configure network properly.

cat > /etc/network/interfaces
auto lo
iface lo inet loopback
allow-hotplug usb0
iface usb0 inet static
    address 172.16.0.2
    netmask 255.255.255.0
    network 127.16.0.0
    broadcast 172.16.0.255
    gateway 172.16.0.1
    dns-nameservers 1.1.1.1
