比特币编译（Ubuntu 16.04）

• 安装比特币需要的所有库

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

sudo apt-get install libboost-all-dev

• GUI：关于QT的各种库

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

　　出现了错误，有些包无法下载：

　　解决方法：参考 https://blog.csdn.net/tiny_lxf/article/details/75027865

sudo vim /etc/resolv.conf 
修改 nameserver 8.8.8.8

　　再次运行上面的GUI安装，成功

• git源码

sudo apt-get install git
git clone https://github.com/bitcoin/bitcoin.git

• 安装Berkeley DB：推荐使用Berkeley DB 4.8

cd bitcoin
./contrib/install_db4.sh `pwd`

• 配置

./autogen.sh
./configure

　　出现报错：原因是找不到berkeleyDB的相关头文件导致的（参考 https://blog.csdn.net/xocoder/article/details/78914576）

报错：libdb_cxx headers missing, Bitcoin Core requires this library for wallet functionality (–disable-wallet to disable wallet functionality)

 　　上面安装db的脚本执行后其实会提示：

When compiling bitcoind, run `./configure` in the following way:

export BDB_PREFIX='/home/zhang/bitcoin/db4'
./configure BDB_LIBS="-L${BDB_PREFIX}/lib -ldb_cxx-4.8" BDB_CFLAGS="-I${BDB_PREFIX}/include" ...

所以，应当设置bash环境变量BDB_PREFIX为刚才指定的安装目录，并在configure时，提供这个环境变量

解决步骤：

vim ~/.bashrc
export BDB_PREFIX='/home/zhang/bitcoin/db4'

source ~/.bashrc
./configure BDB_LIBS="-L${BDB_PREFIX}/lib -ldb_cxx-4.8" BDB_CFLAGS="-I${BDB_PREFIX}/include"

• 编译

make
make install 

出现错误：

[install-libLTLIBRARIES] Error 1

[install-recursive] Error 1

解决方法：

sudo make install

• 测试

$ which bitcoind
/usr/local/bin/bitcoind
$ which bitcoin-cli
/usr/local/bin/bitcoin-cli

　　

bitcoind
bitcoin-qt
bitcoin-cli

or
./src/bitcoind 
./src/qt/bitcoin-qt 
./src/bitcoin-cli
