一. 安装开发环境

sudo apt-get update
sudo apt-get install build-essential libtool autotools-dev autoconf pkg-config libssl-dev

sudo apt-get install libboost-all-dev

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

sudo apt-get install libqrencode-dev

sudo apt-get install libminiupnpc-dev

sudo apt-get install git

二.下载源码

mkdir btcoin

../dist/configure --enable-cxx --disable-shared --with-pic --prefix=/usr/local
sudo make install

网上的教程很乱，具体碰到问题，大家可以参考doc文件目录里面的build-XX说明文件，很详细。
