从零到壹学习EOS 第一讲：搭建EOS开发环境

支持的操作系统

Amazon 2017.09 and higher

Centos 7

Fedora 25 and higher (Fedora 27 recommended)

Mint 18

Ubuntu 16.04 (Ubuntu 16.10 recommended)

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

mac 基础环境

# 安装 xcodexcode-select --install# 安装 Homebrewruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

获取并编译 EOS

下载 eos

$ git clone https://github.com/eosio/eos --recursive$ cd eos$ git checkout dawn-v3.0.0

如果克隆代码时未带 参数，那么可切换到项目路径下面执行如下命令，更新子模块。

$ git submodule update --init --recursive

编译源码生成可执行文件

$ ./eosio_build.sh

编译时间比较长，需要耐心等待，大约30分钟～50分钟，编译成功：

附带的可执行程序:

： 区块链服务器节点生成组建

： 和区块链交互的接口命令

： EOS 钱包

：节点网络组成和部署的应用

所有这些程序都存在于这个文件夹

mac 下遇到的问题

CMake Error at /usr/local/Cellar/cmake/3.11.1/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:137 (message):Failed to find Gettext libintl (missing: Intl_INCLUDE_DIR)Call Stack (most recent call first):/usr/local/Cellar/cmake/3.11.1/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:378 (_FPHSA_FAILURE_MESSAGE)/usr/local/Cellar/cmake/3.11.1/share/cmake/Modules/FindIntl.cmake:47 (FIND_PACKAGE_HANDLE_STANDARD_ARGS)programs/cleos/CMakeLists.txt:29 (find_package)

解决方法：brew unlink gettext && brew link --force gettext

运行一个单节点网络

$ cd build/programs/nodeos$ ./nodeos

如下图所示，执行完./nodeos程序后会抱错

出现上面错误，我们需要配置一下config.ini

Mac OS: ~/Library/Application Support/eosio/nodeos/config

Linux: ~/.local/share/eosio/nodeos/config

$ cd ~/Library/Application\ Support/eosio/nodeos/config$ lsconfig.inigenesis.jsonvi config.ini

修改内容，如下图所示：

修改完 ，然后重新进入 执行 ``

$ cd /Users/fujinliang/workspace/eos/build/programs/nodeos/$ ./nodeos

运行成功，结果如下：

查看区块信息

进入 目录，执行 可以查询区块的信息

$ cd /Users/fujinliang/workspace/eos/build/programs/cleos$ ./cleos get info{ "server_version": "d9ad8eec", "head_block_num": 104, "last_irreversible_block_num": 103, "head_block_id": "0000006820981a892839ba2789e50e18d10acef786cf7b561d3a0c681275008a", "head_block_time": "2018-04-28T08:59:05", "head_block_producer": "eosio"}
