Revision as of 16:57, 9 March 2014
Ubuntu 12.04.4 LTS (Hard Float) is the default IGEPv5 base distribution (it's included in IGEPv5 Full and Lite). We will learn about install, use, generate packages, upgrade ...
Overview
What we learn in this chapter? Install, play and fun ...
Contents
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
Installing qemu-user-static for armhf-on-x86 support (natty or later) Reading package lists... Done Building dependency tree Reading state information... Done The following extra packages will be installed: binfmt-support The following NEW packages will be installed: binfmt-support qemu-user-static 0 upgraded, 2 newly installed, 0 to remove and 23 not upgraded. Need to get 12.9 MB of archives. After this operation, 33.9 MB of additional disk space will be used. 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 ...
