Compiling Bitcoin Core Source Code : Ubuntu 16.04 LTS

1.   Bitcoin Core is the reference implementation of bitcoin and anyone ON with any projects around bitcoin would need to compile the bitcoin source code to create the bitcoind for his/her own node. Ubuntu is usually the operating system recommended to run Bitcoin Core.This post will build upon with screenshots as done and terminal commands as executed to compile the same vide GIT.

2.  The machine I have used here is a Ubuntu 64 bit running on a virtual box platform with the following details as seen in the screenshot :

Now on I will just share the terminal commands as i executed in the terminal :

sudo apt-get update

sudo apt-get upgrade

sudo apt-get install git

Search for Bitcoin github and click the first link as seen below :

Goto the link as seen below at https://github.com/bitcoin/bitcoin/blob/master/doc/build-unix.md

sudo git clone https://github.com/bitcoin/bitcoin.git

sudo apt-get install build-essential libtool autotools-dev automake pkg-config libssl-dev libevent-dev bsdmainutils python3

 

sudo apt-get install libboost-system-dev libboost-filesystem-dev libboost-chrono-dev libboost-program-options-dev libboost-test-dev libboost-thread-dev

 

sudo apt-get install libboost-all-dev

sudo apt-get install software-properties-common

sudo add-apt-repository ppa:bitcoin/bitcoin

sudo apt-get update

sudo apt-get install libdb4.8-dev libdb4.8++-dev

sudo apt-get install libminiupnpc-dev

 

sudo apt-get install libzmq3-dev

sudo apt-get install libqt5gui5 libqt5core5a libqt5dbus5 qttools5-dev qttools5-dev-tools libprotobuf-dev protobuf-compiler

sudo apt-get install libqrencode-dev

sudo ./autogen.sh

sudo ./configure --disable-wallet #

sudo make

and the last command

sudo make install

....and you r ready to go.....

Installing Broadcom drivers : Kali Linux

1.     This post will show the installation of Broadcom's official Linux hybrid wireless driver. Using a Broadcom wireless USB adapter gives us the greatest possibility of success in terms of getting our wireless USB access point to work on Kali.

2.    Open a terminal window and download the appropriate Broadcom driver from http://www.broadcom.com/support/802.11/linux_sta.php

cd /tmp/

wget http://www.broadcom.com/docs/linux_sta/hybrid-portsrc_
x86_64-v5_100_82_112.tar.gz

3.     Extract the downloaded driver using the following script:

mkdir broadcom

tar xvfz hybrid-portsrc_x86_64-v5_100_82_112.tar.gz –C /tmp/broadcom

4.     Modify the wl_cfg80211.c file since there's a bug in version 5.100.82.112 that prevents compiling the code under kernel version 2.6.39

vim /tmp/broadcom/src/wl/sys/wl_cfg80211.c

Look at the following piece of code at line number 1814:

#if LINUX_VERSION_CODE > KERNEL_VERSION(2, 6, 39)

Replace it with the following:

#if LINUX_VERSION_CODE >= KERNEL_VERSION(2, 6, 39)

Save the changes.

5.     Compile the code:

make clean
make
make install

6.     Update the dependencies:

depmod -a

7.     Find loaded modules by issuing the following:

lsmod | grep b43\|ssb\|bcma

8.     Remove the modules found by executing the following command:

rmmod b43

Where could be b43 or ssb or bcma.

9.     Blacklist the modules to prevent them from loading at system startup:

echo "blacklist " >> /etc/modprobe.d/blacklist.conf

Where could be b43 or ssb or bcma or wl.

10.     Finally, add the new module to the Linux Kernel to make it a part of the boot process:

modprobe wl
