How to install bitcoin 0.8.0 on debian squeeze amd64

Thank GNUtransfer the loan us a VPS and other resources to write this article.
While it is a bit tedious to install bitcoind 0.8.0 on Debian Squeeze, improvements in this version make it worth the work, performance is far superior to previous versions and I/O disk have been significantly reduced.
Now let’s start with the installation.

We must ensure we have the backports repositories, and the updated system.
Our sources.list should look like this.

root@vps146167:/# cat /etc/apt/sources.list
#
deb http://ftp.us.debian.org/debian/ squeeze main non-free contrib
deb-src http://ftp.us.debian.org/debian/ squeeze main non-free contrib

deb http://security.debian.org/ squeeze/updates main contrib non-free
deb-src http://security.debian.org/ squeeze/updates main contrib non-free

# squeeze-updates, previously known as 'volatile'
deb http://ftp.us.debian.org/debian/ squeeze-updates main contrib non-free
deb-src http://ftp.us.debian.org/debian/ squeeze-updates main contrib non-free

deb http://backports.debian.org/debian-backports squeeze-backports main contrib non-free
deb-src http://backports.debian.org/debian-backports squeeze-backports main contrib non-free

Then add the repository sources of bitcoin for Ubuntu Precise Pangolin.

Create the file /etc/apt/sources.list.d/bitcoin.list with the following content

root@vps146167:/# cat /etc/apt/sources.list.d/bitcoin.list

deb-src http://ppa.launchpad.net/bitcoin/bitcoin/ubuntu precise main

root@vps146167:/# 

Then add the key in apt

root@vps146167:/# gpg --keyserver hkp://subkeys.pgp.net --recv-keys D46F45428842CE5E
gpg: directory `/root/.gnupg' created
gpg: new configuration file `/root/.gnupg/gpg.conf' created

root@vps146167:/# gpg --export --armor D46F45428842CE5E | apt-key add --
OK
root@vps146167:/# 

We update the repositories

apt-get update

Then install the following packages (from backports) dpkg-dev, qt4-qmake, libdb4.7++-dev, libqt4-dev, libqrencode-dev, libminiupnpc-dev, libboost-test1.42-dev, zlib1g, lib32z1, libc6-i386, bash-completion

apt-get -t squeeze-backports install dpkg-dev qt4-qmake libdb4.7++-dev libqt4-dev libqrencode-dev libminiupnpc-dev libboost-test1.42-dev zlib1g lib32z1 libc6-i386 bash-completion

Then install the build-dep also from backports

apt-get -t squeeze-backports build-dep bitcoind

Then we create the directory /usr/src/bitcoin and enter in, from there proceed to download the source package of bitcoin

mkdir -p /usr/src/bitcoin
cd /usr/src/bitcoin
apt-get source bitcoin

We entered the bitcoin-0.8.0 directory

cd bitcoin-0.8.0

Then edit the file «debian/changelog» and add these 6 lines (this is not really necessary is for the files .deb take the squeeze chain name instead of precise)

bitcoin (0.8.0-squeeze1) squeeze; urgency=low

  * Mark for squeeze.

Then proceed to the compilation with the following command (this may take some time, between 10 and 30 minutes, even more in some cases)

./debian/rules clean
./debian/rules binary

Once we have finished compiling, two packages in top directory. bitcoind and bitcoin-qt, we will use the bitcoind.
We proceed to install

cd ..
root@vps146167:/usr/src/bitcoin# dpkg -i bitcoind_0.8.0-squeeze1_amd64.deb 
Selecting previously deselected package bitcoind.

Usually we have it installed in a future article we will see how to configure it to start automatically in the background at startup.
