EOS合約開發第二章-EOS開發環境建構

EOS開發環境建構

一、擷取代碼

從git下載下傳eos項目以及其依賴的子項目：

git clone https://github.com/EOSIO/eos --recursive
           

如果下載下傳時沒有添加--recursive，可以在下載下傳的eos項目目錄下運作以下指令來下載下傳依賴的子項目：

git submodule update --init --recursive
           

因為我們需要一個穩定可用的版本來進行開發和測試，截止目前最新的穩定版本是dawn4.0，我們編譯dawn4.0版本且後續開發以及測試都基于此版本進行。

git checkout dawn-v4.0.0
           

二、自動編譯EOSIO

這是編譯eosio的簡單方法，使用了自動編譯的腳本，自動編譯腳本會根據系統平台來建構項目。

目前支援的os平台有：

1.Amazon 2017.09 and higher.

2.Centos 7.

3.Fedora 25 and higher (Fedora 27 recommended).

4.Mint 18.

5.Ubuntu 16.04 (Ubuntu 16.10 recommended).

6.MacOS Darwin 10.12 and higher (MacOS 10.13.x recommended).

系統配置需求：

1.8GB RAM free required

2.20GB Disk free required

啟動自動編譯腳本執行編譯：

cd eos
./eosio_build.sh
           

安裝：

cd build
Sudo make install
           

三、手動編譯EOSIO

我們将在centos 7上進行手動編譯eosio項目。

1. 安裝development toolkit

sudo yum --enablerepo=extras install centos-release-scl
sudo yum update
sudo yum install -y devtoolset-7
scl enable devtoolset-7 bash
sudo yum install -y python33.x86_64
scl enable python33 bash
sudo yum install git autoconf automake libtool make bzip2 \
				 bzip2-devel.x86_64 openssl-devel.x86_64 gmp-devel.x86_64 \
				 ocaml.x86_64 doxygen libicu-devel.x86_64 python-devel.x86_64 \
				 gettext-devel.x86_64
           

2. 安裝cmake

cd ~
curl -L -O https://cmake.org/files/v3.10/cmake-3.10.2.tar.gz
tar xf cmake-3.10.2.tar.gzcd cmake-3.10.2
./bootstrap
make -j$( nproc )
sudo make install
           

3. 安裝boost

cd ~

./bootstrap.sh "--prefix=$BOOST_ROOT"
./b2 install
           

4. 安裝mongodb

mkdir ${HOME}/optcd ${HOME}/opt

mkdir ${HOME}/opt/mongodb/data
mkdir ${HOME}/opt/mongodb/log
touch ${HOME}/opt/mongodb/log/mongod.log
		
tee > /dev/null ${HOME}/opt/mongodb/mongod.conf <<mongodconfsystemLog: destination: file path: ${HOME}/opt/mongodb/log/mongod.log logAppend: true logRotate: reopennet: bindIp: 127.0.0.1,::1 ipv6: truestorage: dbPath: ${HOME}/opt/mongodb/datamongodconf
