EOS合约开发第二章-EOS开发环境构建

EOS开发环境构建

一、获取代码

从git下载eos项目以及其依赖的子项目：

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

如果下载时没有添加--recursive，可以在下载的eos项目目录下运行以下命令来下载依赖的子项目：

git submodule update --init --recursive

因为我们需要一个稳定可用的版本来进行开发和测试，截止目前最新的稳定版本是dawn4.0，我们编译dawn4.0版本且后续开发以及测试都基于此版本进行。

git checkout dawn-v4.0.0

二、自动编译EOSIO

这是编译eosio的简单方法，使用了自动编译的脚本，自动编译脚本会根据系统平台来构建项目。

目前支持的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).

系统配置需求：

1.8GB RAM free required

2.20GB Disk free required

启动自动编译脚本执行编译：

cd eos
./eosio_build.sh

安装：

cd build
Sudo make install

三、手动编译EOSIO

我们将在centos 7上进行手动编译eosio项目。

1. 安装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. 安装cmake

cd ~

./bootstrap
make -j$( nproc )
sudo make install

3. 安装boost
