1.首先從github上clone最新的bitcoin源代碼
git clone https://github.com/bitcoin/bitcoin.git
2.進入clone下來的代碼目錄，查看當前版本(這里我切換到了v0.20.0版本)
cd ./bitcoin git tag -l git checkout v0.20.0
3.安裝autoconf，安裝成功之后運行代碼目錄下的./autogen.sh
sudo apt install autoconf ./autogen.sh
4.出現了錯誤信息，configure: error: PKG_PROG_PKG_CONFIG macro not found. Please install pkg-config and re-run autogen.sh，提示安裝libtool，如果沒有安裝gcc，g++還需要安裝這兩項，安裝完成之后再一次運行./autogen.sh應該就可以成功了，運行成功之后會在代碼目錄下生成./configure
sudo apt install libtool gcc g++ ./autogen.sh
5.運行./configure，出現錯誤，需要安裝pkg-config之后重新./autogen.sh(倒退回上面步驟了)
sudo apt install pkg-config ./autogen.sh
6.再次報錯，configure: error: libdb_cxx headers missing, Bitcoin Core requires this library for wallet functionality (--disable-wallet to disable wallet functionality)，安裝libdb++-dev可解決問題，安裝之后重新./configure
sudo apt install libdb++-dev
7.出現了一個警告和一個錯誤，
checking for QT5... no
configure: WARNING: Qt dependencies not found; bitcoin-qt frontend will not be built
checking whether to build Bitcoin Core GUI... no
checking for Berkeley DB C++ headers... default
configure: error: Found Berkeley DB other than 4.8, required for portable wallets (--with-incompatible-bdb to ignore or --disable-wallet to disable wallet functionality)
或者qt5安裝之后有警告
configure: WARNING: LRELEASE not found; bitcoin-qt frontend will not be built
需要安裝qt5-default和qttools5-dev-tools，以及從源代碼編譯Berkeley DB
sudo apt install qt5-default qttools5-dev-tools
編譯Berkeley DB
wget http://download.oracle.com/berkeley-db/db-4.8.30.NC.tar.gz tar -xzvf db-4.8.30.NC.tar.gz cd db-4.8.30.NC/build_unix ../dist/configure --enable-cxx make sudo make install
8.加入參數重新運行./configure
./configure CPPFLAGS="-I/usr/local/BerkeleyDB.4.8/include -O2" LDFLAGS="-L/usr/local/BerkeleyDB.4.8/lib"
報錯
checking for boostlib >= 1.47.0 (104700)... configure: We could not detect the boost libraries (version MINIMUM_REQUIRED_BOOST or higher). If you have a staged boost library (still not installed) please specify $BOOST_ROOT in your environment and do not give a PATH to --with-boost option. If you are sure you have boost installed, then check your version number looking in <boost/version.hpp>. See http://randspringer.de/boost for more documentation.

configure: error: libevent version 2.0.21 or greater not found.
把這些依賴一下裝齊了吧
sudo apt install libevent-dev libzmq5-dev doxygen libboost1.58-all-dev
然后重新
./configure CPPFLAGS="-I/usr/local/BerkeleyDB.4.8/include -O2" LDFLAGS="-L/usr/local/BerkeleyDB.4.8/lib"
這個時候依然還是有一個警告，目前暫未找到解決的方法，但是不影響編譯的功能
configure: WARNING: "xgettext is required to update qt translations"
9../configure沒有問題，之后就可以make了，bitcoin項目比較大編譯的時間可能需要半小時，耐心等待吧
