安装

源代码

从github下载源代码，命令如下：

git clone https://github.com/bitshares/bitshares-core
git submodule update --init --recursive

环境

我机器上gcc版本还是4.0，先用brew安装最新版的各种工具再说

Chaim:bitshares-core Chaim$ brew install boost cmake git openssl autoconf automake

编译bitshares

Chaim:bitshares-core Chaim$ cmake .

此步报错，找不到boost库

CMake Error at libraries/fc/CMakeModules/FindBoost.cmake:1129 (message):
  Unable to find the requested Boost libraries.

  Boost version: 1.53.0

  Boost include path: /usr/local/include

  Detected version of Boost is too old.  Requested version was 1.57 (or
  newer).

下载Boost1.66版本，并编译安装，执行：

Chaim:bitshares-core Chaim$ cmake -DBOOST_ROOT=/usr/local/opt/boost -DOPENSSL_ROOT_DIR=/usr/local/opt/openssl .

编译还是出错，赶紧仔细看README，里面说明需要Boost和OpenSSL的版本需求，按它的版本下载安装

**NOTE:** BitShares requires an [OpenSSL](https://www.openssl.org/) version in the 1.0.x series. OpenSSL 1.1.0 and newer are NOT supported. If your system OpenSSL version is newer, then you will need to manually provide an older version of OpenSSL and specify it to CMake using `-DOPENSSL_INCLUDE_DIR`, `-DOPENSSL_SSL_LIBRARY`, and `-DOPENSSL_CRYPTO_LIBRARY`.

**NOTE:** BitShares requires a [Boost](http://www.boost.org/) version in the range [1.57, 1.63]. Versions earlier than
1.57 or newer than 1.63 are NOT supported. If your system Boost version is newer, then you will need to manually build
an older version of Boost and specify it to CMake using `DBOOST_ROOT`.

看下现有安装版本：

Chaim:bitshares-core Chaim$ brew list openssl
/usr/local/Cellar/openssl/1.0.2o_1/.bottle/etc/ (8 files)

openssl是1.0.x

但刚安装的boost是1.66.0，这个版本太 高了，下个1.63试试，官网下载编译，运行cmake指定位置

Chaim:bitshares-core Chaim$ cmake -DBOOST_ROOT=/Users/Chaim/Documents/workspace/boost_1_63_0

再执行make

Chaim:bitshares-core Chaim$ make
[  3%] Built target project_secp256k1
[  6%] Built target project_editline

到70%居然还出错了...

搜索到原因是mac的一些兼容问题，用develop版本已解决，试试：

Chaim:bitshares-core Chaim$ cd libraries/fc
Chaim:fc Chaim$ git checkout master
Chaim:fc Chaim$ git pull
Chaim:bitshares-core Chaim$ make clean
Chaim:bitshares-core Chaim$ make

执行，吃完中饭回来，结果如下：

运行

OK！开始同步了！

附一 mac下安装boost

电脑上装的boost还是2013年创业做手游时1.53的版本，后来很少做这方面的开发，一直没有更新，最近有需要使用，连安装都忘了，这次把安装过程记录下来。

Boost官网下载最新版本，现在是1.66

Chaim:boost_1_66_0 Chaim$ ./bootstrap.sh 
Building Boost.Build engine with toolset darwin... tools/build/src/engine/bin.macosxx86_64/b2
Detecting Python version... 2.7
Detecting Python root... /opt/local/Library/Frameworks/Python.framework/Versions/2.7
Unicode/ICU support for Boost.Regex?... not found.
Generating Boost.Build configuration in project-config.jam...

Bootstrapping is done. To build, run:

    ./b2
    
To adjust configuration, edit 'project-config.jam'.
Further information:

     ./b2 --help
     
   - Getting started guide:

   - Boost.Build documentation:

Chaim:boost_1_66_0 Chaim$ sudo ./b2 --buildtype=complete install
