BCH源码编译

BCH是BTC的硬分叉币，代码来源于BTC
还是新建一个虚拟机，ubuntu 很好使接着用这个,版本16

sudo apt-get update
sudo apt-get install git-core

下载源码，目前最新0.18.1

sudo git clone  https://github.com/Bitcoin-ABC/bitcoin-abc

在本地保存在bitcoin-abc目录下

parallels@parallels-vm:~/bitcoin-abc$ ls
arcanist        configure.ac     doc                        README.md
autogen.sh      contrib          Dockerfile-doxygen         share
build-aux       CONTRIBUTING.md  INSTALL.md                 src
cmake           COPYING          libbitcoinconsensus.pc.in  test
CMakeLists.txt  depends          Makefile.am

查看doc下的build-unix.md文档，因为我是装在ubuntu的
需要调整虚拟机内存到1.5G以上

C++ compilers are memory-hungry. It is recommended to have at least 1.5 GB of memory available when compiling Bitcoin ABC.

安装依赖

sudo apt-get install build-essential libtool autotools-dev automake pkg-config libssl-dev libevent-dev bsdmainutils
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 libdb-dev libdb++-dev//BerkeleyDB 5.3

需要GUI的话

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

安装

sudo ./autogen.sh
sudo ./configure --with-incompatible-bdb --enable-debug

执行后我的一些配置

Options used to compile and link:
  with wallet   = yes
  with gui / qt = yes
    qt version  = 5
    with qr     = auto
  with zmq      = no
  with test     = yes
  with bench    = yes
  with upnp     = auto
  use asm       = yes
  debug enabled = yes
  werror        = no

  sanitizers    
          asan  = no
          tsan  = no
          ubsan = no

  target os     = linux
  build os      = 

  CC            = gcc
  CFLAGS        = -g -O2 -g3 -O0
  CPPFLAGS      =  -DDEBUG -DDEBUG_LOCKORDER -DHAVE_BUILD_INFO -D__STDC_FORMAT_MACROS
  CXX           = g++ -std=c++11
  CXXFLAGS      = -g -O2 -g3 -O0 -Wall -Wextra -Wformat -Wvla -Wformat-security -Wno-unused-parameter
  LDFLAGS       =

接下来,这一步比较久

sudo make

然后

sudo make check 
sudo make install

就有如下的可执行命令吧

libtool: install: /usr/bin/install -c bitcoind /usr/local/bin/bitcoind
libtool: install: /usr/bin/install -c bitcoin-seeder /usr/local/bin/bitcoin-seeder
libtool: install: /usr/bin/install -c bitcoin-cli /usr/local/bin/bitcoin-cli
libtool: install: /usr/bin/install -c bitcoin-tx /usr/local/bin/bitcoin-tx
libtool: install: /usr/bin/install -c test/test_bitcoin /usr/local/bin/test_bitcoin
libtool: install: /usr/bin/install -c bench/bench_bitcoin /usr/local/bin/bench_bitcoin
libtool: install: /usr/bin/install -c qt/bitcoin-qt /usr/local/bin/bitcoin-qt
libtool: install: /usr/bin/install -c qt/test/test_bitcoin-qt /usr/local/bin/test_bitcoin-qt

按照比特币的配置，新建～/.bitcoin/bitcoin.conf

alertnotify=myemailscript.sh "Alert: %s"
maxconnections=15
prune=5000
minrelaytxfee=0.0001
maxmempool=200
maxreceivebuffer=2500
maxsendbuffer=500
rpcuser=bitcoinrpc
rpcpassword=CHANGE_THIS
testnet=1

启动

sudo bitcoind -printtoconsole

或者

sudo bitcoin-qt

这里写图片描述
比较奇怪的是，bitcoin-cli在bitcoin-qt开启期间是不能用的，得在bitcoind期间才能用，难道bitcoin-qt没注册rpc么？

安装sublime3,官网步骤，第一步失败了三次，多尝试几次就好

parallels@parallels-vm:~$ wget -qO - https://download.sublimetext.com/sublimehq-pub.gpg | sudo apt-key add -
[sudo] password for parallels: 
gpg: no valid OpenPGP data found.
parallels@parallels-vm:~$ wget -qO - https://download.sublimetext.com/sublimehq-pub.gpg | sudo apt-key add -
OK
parallels@parallels-vm:~$ sudo apt-get install apt-transport-https

然后按步骤

echo "deb https://download.sublimetext.com/ apt/stable/" | sudo tee /etc/apt/sources.list.d/sublime-text.list
sudo apt-get update
sudo apt-get install sublime-text

插件

总结
BCH的源码结构和BTC是基本一致的，应该会针对两者不同点来看，比如区块扩容，隔离见证部分的实现代码
