比特幣BTC原始碼分析(0):環境搭建

一、Bitcoin編譯執行啟動過程
1、從Github上clone bitcoin原始碼 至本地
~/go/src/github.com/bitcoin$git clone https://github.com/bitcoin/bitcoin.git
Cloning into 'bitcoin'...
remote: Enumerating objects: 16, done.
remote: Counting objects: 100% (16/16), done.

Resolving deltas: 100% (88524/88524), done.
~/go/src/github.com/bitcoin
2、根據官方文件指導進行編譯安裝
各系統版本安裝方法:
Mac -osx
Linux
Window
主要命令:
~/go/src/github.com/bitcoin/bitcoin$./autogen.sh
#開啟debug進行configure配置
~/go/src/github.com/bitcoin/bitcoin$./configure -with-gui --enable-debug
#成功配置結果如下
Options used to compile and link:
with wallet = yes
with gui / qt = yes
with bip70 = yes
with qr = yes
with zmq = no
with test = yes
with bench = yes
with upnp = yes
use asm = yes
sanitizers =
debug enabled = yes
gprof enabled = no
werror = no
target os = darwin
build os = darwin
CC = gcc
CFLAGS = -g -O2
CPPFLAGS = -DDEBUG -DDEBUG_LOCKORDER -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=2 -DHAVE_BUILD_INFO -D__STDC_FORMAT_MACROS -I/usr/local/opt/[email protected]/include -DMAC_OSX
CXX = g++ -std=c++11
CXXFLAGS = -Og -g3 -ftrapv -Wstack-protector -fstack-protector-all -Wall -Wextra -Wformat -Wvla -Wformat-security -Wthread-safety-analysis -Wrange-loop-analysis -Wredundant-decls -Wno-unused-parameter -Wno-self-assign -Wno-unused-local-typedef -Wno-deprecated-register -Wno-implicit-fallthrough
LDFLAGS = -pthread -Wl,-headerpad_max_install_names -Wl,-dead_strip
ARFLAGS = cr
~/go/src/github.com/bitcoin/bitcoin$make check
3、編譯結果目錄結構
(1)./src/為整個比特幣核心的程式碼,由C++編寫;
(2)./src/bitcoind為比特幣核心啟動程式;
(3)./src/bitcoin-cli為客戶端控制程式,命令列中會用到;
(4)./qt/為qt專案目錄,qt的客戶端其實就是呼叫了bitcoind和bitcoin-cli的介面。
4、安裝目錄(包含輸出日誌、區塊鏈等等)
預設在其他目錄下:
Linux在~/.bitcoin中;
Mac在/User/YOURNAME/Library/Application Support/Bitcoin中,不太好找,用前往或者終端;
windows在C盤下的Bitcoin。
如果想在程式碼裡改改預設路徑可以去./src/utils.h第455行左右,找GetDefaultDataDir函式。
可用命令列跟蹤日誌檔案,日誌檔案在上面說的bitcoin資料夾裡面(mac上直接點開檔案就行)
5、命令列啟動
(1)命令列啟動客戶端
~/go/src/github.com/bitcoin/bitcoin$./src/bitcoind
~/go/src/github.com/bitcoin/bitcoin$./src/bitcoind -daemon #後臺啟動,一般都要加,然後在debug.log裡看輸出就行
~/go/src/github.com/bitcoin/bitcoin$./src/bitcoind -gen=1 #自動挖礦
~/go/src/github.com/bitcoin/bitcoin$./src/bitcoind help #其他的自己看去吧
(2)操作客戶端
~/go/src/github.com/bitcoin/bitcoin$./src/bitcoin-cli stop
~/go/src/github.com/bitcoin/bitcoin$./src/bitcoin-cli getinfo #檢視當前資訊
~/go/src/github.com/bitcoin/bitcoin$./src/bitcoin-cli getpeerinfo #檢視其他節點
~/go/src/github.com/bitcoin/bitcoin$./src/bitcoin-cli help #其他的自己看去吧
