Introduction:
Since I know how is difficult if for the begginers to start working with crossbuild, I'm going to show what I did to set up the crossbuild environment in practice. The crossbuild environment is just a chroot enabled to build packages for a different architecture then the native one. In this project, the target architecture is the armhf and the native architecture is the amd64.


############## Building the Crossbuild toolchain

In order to build the crossbuild toolchain, we are going to use the following versions of files

Steps: (You should be root or use sudo instead)
1) Setup the chroot to build the crosscompiler
debootstrap unstable debian_chroot_buildcrosstoolchain

2) Entering in the chroot environment
cd debian_chroot_buildcrosstoolchain
mount -t proc none ./proc
mount -o bind /dev ./dev
mount -o bind /dev/pts ./dev/pts
cp /etc/resolv.conf ./etc/resolv.conf
chroot ./ /bin/bash

3) 

############## Installing the Crossbuild toolchain

Steps: (You should be root or use sudo instead)
1) First you need to copy the .deb files builded in the last step and the binutils-

2) Setup the chroot to install the crosscompiler
debootstrap --variant=minbase unstable debian_unstable_native_minimal

3) Entering in the chroot environment
cd debian_unstable_native_minimal
mount -t proc none ./proc
mount -o bind /dev ./dev
mount -o bind /dev/pts ./dev/pts
cp /etc/resolv.conf ./etc/resolv.conf
chroot ./ /bin/bash

4) Install the perl-modules packages
apt-get --no-install-recommends install perl-modules

5) Upgrade the chroot environment to experimental packages

6) Install the packages built in
