Compiling Bitcoind on Raspberry Pi

bitcoin-logo-plain

A short step-by-step on how to compile Bitcoind on Raspberry Pi.

First thing you need to do is to increase the RPi’s Swap Size

$ sudo vim /etc/dphys-swapfile

Modify the line to change the setting from 100Mb to 500Mb.
CONF_SWAPSIZE=100
to
CONF_SWAPSIZE=500

Apply the changes
$ sudo dphys-swapfile setup
$ sudo dphys-swapfile swapoff
$ sudo dphys-swapfile swapon

Check the new swap size using free command
$ free

Update your Raspberry Pi’s packages
$ sudo apt-get update
$ sudo apt-get upgrade

Install all dependencies needed to compile the bitcoind
$ sudo apt-get install checkinstall subversion git git-core build-essential

$ sudo apt-get install libtool autotools-dev autoconf

$ sudo apt-get install libssl-dev libdb++-dev libminiupnpc-dev

$ sudo apt-get install libboost-dev libboost-system-dev libboost-filesystem-dev libboost-program-options-dev libboost-thread-dev libboost-all-dev

After successfully installing the packages, go to your preferred directory for downloading the bitcoind source code to compile.
$ cd ~
$ mkdir source
$ cd source
$ git clone git://github.com/bitcoin/bitcoin.git
$ cd ~/source/bitcoin/src

Prepare the bitcoin source code from github
$ ./autogen.sh
$ ./configure --without-gui

Now… grab something to eat or to watch while compiling. It’s gonna take a long while to compile.

After a few (maybe hours)…  you may now configure your bitcoin.conf and run
$  ~/source/bitcoin/src/bitcoind -daemon

 

Watch out for my next post on setting-up bitcoind (bitcoin.conf settings)

Update:

For minimal configuration… create this file in ~/.bitcoin/bitcoin.conf


server=1
rpcuser={insert your preferred username}
rpcpassword={insert your preferred long hash password for security}
rpctimeout=30
rpcport=8332
gen=0
allowreceivebyip=1

Raspberry Pi Wireless Access Point using Tenda Wireless USB Adapter

Tenda W311U+ Wireless N150 High Gain USB Adapter
Tenda W311U+ Wireless N150 High Gain USB Adapter

You can make your own Wireless Access Point with Raspberry Pi using Tenda Wireless USB Adapter (W311U+).    It won’t give you the same performance like the commercial one… but it will allow you to connect at least 5 devices and install network security packages to play with 🙂  neat!

Bought from Octagon Megamall with PhP600 price tag.  You can also try other Wireless USB adapters like CDR-King’s… but check if it can operate on “Software AP” mode.

Samsung just released version 1.33 firmware for their NX300, and now ready for download.  You may install it through i-Launcher program or by copying the firmware directly to SD memory card.  The recent update highlights five major items:

1.  Remote View Finder – add touch AF function
2.  Remote View Finder – add streaming quality option
3.  Improve connection speed to Android
4.  Improve Movie Recording
5.  Improve full time manual focus for 60mm and 85mm lenses

Impressive update… but still hoping that they’ll include a very basic function like time-lapse on their next release.
