Overview

What we learn in this chapter? Install, play and fun ...

Host Enviroment

We suggest use Ubuntu 12.04.4 LTS (32 bits) in your host, you can download it from our server using this link or directly from Ubuntu (Canonical) website. You can install it in a Virtual Machine enviroment using any Virtualization software or directly in your PC.

After install is recommended update the package list with:

sudo apt-get update

Install Development packages

Now is time to install some packages.

GCC, G++, libc Cross Compiler

You can install the cross compiler if you want to build u-boot, linux kernel or applications using your host PC and compile for IGEPv5 as target.

sudo apt-get install gcc-arm-linux-gnueabihf g++-arm-linux-gnueabihf libc6-dev-armhf-armel-cross libc6-armel-armhf-cross

Pbuilder

A pbuilder environment is a chrooted environment which can have a different distroseries or architecture than your host system.

sudo apt-get install pbuilder pbuilder-scripts

What can I do?

pbuilder is used for create your own ubuntu/debian based distribution or build your own debian/ubuntu packages.

Setup, the basic setup is create in your home base directory a new file called .pbuilderrc inside you should copy this content:

BINDMOUNTS="${BINDMOUNTS} /home/<your_user>/Projects"

EXTRAPACKAGES="${EXTRAPACKAGES} pbuilder devscripts gnupg patchutils vim-tiny openssh-client"

And just remember create the directory Projects before start. Now if you want to create a new rootfs, you can try to build with

cd ~/Projects
pcreate -a armhf -d precise precise-armhf

The first time the program will ask you about install some dependencies

Do you want to continue [Y/n]? 

You should say, Y (yes) After build (it can take some time) you will get your rootfs (ARM Hard float) in /var/cache/pbuilder/ directory

Now it time to test your new rootfs

First create a new directory in your home:

$ mkdir -p rootfs/armhf_12.04.4

Now untar the generated file:

$ cd ~/rootfs/armhf_12.04.4

$ sudo tar xvfz /var/cache/pbuilder/precise-armhf.tgz

Now copy the qemu-arm-static file into usr/bin directory

$ sudo cp /usr/bin/qemu-arm-static usr/bin

And now chroot it as

$ cd ..

$ sudo chroot armhf_12.04.4

Check if all is ok with:

$ arch

armv7l

Now you've in a chroot armhf emulation your rootfs ...
