MAC本地安装EOS及问题

本地安装EOS

EOS是bm(比特股创始人)最新研发的第三代区块链技术,每秒交易可达到百万级,以太坊每秒也只能达到几十笔。更适合高并发场景。

EOS的代码在github上开源,本文主要内容是如何在本地部署EOS。

  • 系统:Mac最新版

  • 依赖:Boost

  • OpenSSL

  • secp256k1-zkp


依赖环境安装

因为eos是由c++编写,所以我们需要安装cmake等编译工具。如果是linux无需安装,mac需要安装xcode后才可

brew install automake autoconf libtool cmake

这里我们用homebrew包管理工具,更加简单方便些。

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Boost

brew install Boost

OpenSSL

brew install OpenSSL

注意⚠️:因为新版mac已经移除openssl,这里我们安装完需要配置下环境变量

export OPENSSL_ROOT_DIR=/usr/local/Cellar/openssl/1.0.2k

export OPENSSL_INCLUDE_DIR=/usr/local/Cellar/openssl/1.0.2k/includes

secp256k1-zkp

git clone https://github.com/cryptonomex/secp256k1-zkp.git

Cd secp256k1-zkp

./autogen.sh

./configure

make

sudo make install

获取eos代码

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

cd eos

cmake .

make

我们跑一下测试代码

在tests/目录下,双击chain_test即可运行

运行eos

找到programs目录下eosd中,双击执行eosd

这时候会报错,需要我们修改下config.ini文件,全局搜索下此文件

加入

# Load the testnet genesis state, which creates some initial block producers with the default key

genesis-json = /path/to/eos/source/genesis.json

# Enable production on a stale chain, since a single-node test chain is pretty much always stale

enable-stale-production = true

# Enable block production with the testnet producers

producer-id = {"_id":0}

producer-id = {"_id":1}

producer-id = {"_id":2}

producer-id = {"_id":3}

producer-id = {"_id":4}

producer-id = {"_id":5}

producer-id = {"_id":6}

producer-id = {"_id":7}

producer-id = {"_id":8}

producer-id = {"_id":9}

producer-id = {"_id":10}

# Load the block producer plugin, so we can produce blocks

plugin = eos::producer_plugin

当然可以以Docker方式安装

问题集


1  cmake .时,EOSIO/chainbase 下,没有发现CMakeLists.txt文件

=》

git未完成递归下载,手动下载https://github.com/EOSIO/chainbase 分支的,覆盖chainbase文件夹内容

   同样情况的还有appbase binaryen


##############

2  cmake .时,发现找不到 OPENSSL_ROOT_DIR   OPENSSL_INCLUDE_DIR

=》

《1 进入当前用户的home目录
    输入cd ~


《2 编辑.bash_profile   

    输入 vim  .bash_profile


《3在末尾插入  


export OPENSSL_ROOT_DIR=/usr/local/Cellar/openssl/1.0.2k

export OPENSSL_INCLUDE_DIR=/usr/local/Cellar/openssl/1.0.2k/includes

  《4 重新开一个命令行执行命令即可


####################

3 cmake . 时,发现


Could not find a package configuration file provided by "LLVM" (requested

  version 4.0) with any of the following names:

    LLVMConfig.cmake

    llvm-config.cmake

  Add the installation prefix of "LLVM" to CMAKE_PREFIX_PATH or set

  "LLVM_DIR" to a directory containing one of the above files.  If "LLVM"

  provides a separate development package or SDK, be sure it has been

  installed.

=》

《1 下载llvm.....xz

http://releases.llvm.org/download.html#4.0.0    =》Pre-Built Binaries:

mac下的链接为  http://releases.llvm.org/4.0.0/c ... apple-darwin.tar.xz

《2 解压

xz -d clang+llvm-4.0.0-x86_64-apple-darwin.tar.xz   生成tar文件

tar xvf xxx.tar            来解包到目标目录

《3 修改 .bash_profile,在后面追加

export LLVM_DIR = /Users/liyihang/Downloads/clang+llvm-4.0.0-x86_64-apple-darwin/lib/cmake/llvm/LLVMConfig.cmake
