debian wheezy install bitcoin

Install bitcoin 0.9.1 from sources on debian wheezy

The system
$ cat /etc/issue /etc/debian_version;uname -a
Debian GNU/Linux 7 \n \l

Linux testin 3.2.0-4-amd64 #1 SMP Debian 3.2.57-3 x86_64 GNU/Linux

Get bitcoin 0.9.1 or the latest version of bitcoin from or github
$ su
# cd /usr/local/src
# wget

Check, eg:
# chksum=`sha256sum bitcoin-0.9.1-linux.tar.gz | cut -d ' ' -f 1`;
# if [ $chksum == "3fabc1c629007b465a278525883663d41a2ba62699f2773536a8bf59ca210425" ]; then echo 'Checksum OK';fi
Checksum OK

Ungunzip and Untar
# tar xvzf bitcoin-0.9.1-linux.tar.gz

Install Prerequisites
# apt-get install build-essential libtool autotools-dev autoconf libssl-dev

Only db4.8-util from db4.8 (Berkley DB) is in stable wheezy now
We need to add an oldstable repository to /etc/apt/sources eg
# echo "deb oldstable main" >> /etc/apt/sources.list
Update the system sources
# apt-get update
Install db4.8
# apt-get install libdb4.8-dev libdb4.8++-dev

Install libboost, qt4 ,libqrencode and pkg-config
# apt-get install libboost-all-dev libqt4-dev libprotobuf-dev protobuf-compiler pkg-config libqrencode-dev libqrencode3 

Compile and install
# cd bitcoin-0.9.1-linux/src/
# tar xvzf bitcoin-0.9.1.tar.gz
# cd bitcoin-0.9.1
# ./configure --enable-hardening
# make
# cp src/bitcoind /usr/local/bin
# cp src/qt/bitcoin-qt /usr/local/bin/
# cp src/bitcoin-cli /usr/local/bin/
I think that enable-hardening is the default though ...

If you want to set up a wallet for first time
# exit
$ bitcoin-qt
This will take a while

If you want to move your keys aka wallet from another full node just copy your other ~/.bitcoin directory along with your wallet.dat to this system.

There is a good chance you will have to delete the logs,blocks,chainstate, and keys created when you tried to see if bitcoin-qt worked.

If so replace wallet.dat , blocks , and chainstate , remove the logs fireup bitcoin-qt and and wait a couple of hours for "Reindexing blocks on disk..."
$ rm ./bitcoin/blocks
$ rm ./bitcoin/chainstate
$ rm ./bitcoin/db.log
$ rm ./bitcoin/debug.log
$ mv dot-bitcoin-back/block ./bitcoin
$ mv dot-bitcoin-back/chainstate ./bitcoin
$ mv dot-bitcoin-back/wallet.dat ./bitcoin
$ bitcoin-qt
