1. 源代码地址：https://github.com/google/snappy
   
   下载 git clone https://github.com/google/snappy
2. 编译
   
   • 进入snappy源代码文件夹，运行命令： ./autogen.sh
     
     报错 “./autogen.sh: line 3: aclocal: command not found”
     
     通过http://superuser.com/questions/657925/cygwin-rtorrent-installing-libtorrent-autogen-sh-aclocal-not-found这篇文章得知，系统没有安装automake，
     
     运行命令： breaw install automake
     
     报错“-bash: brew: command not found”
     
     安装 brew
     
     运行 命令：ruby -e "$(curl -f sSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
     
     
     
     然后 安装 automake，运行命令： brew install automake
     
     运行命令：./autogen.sh
     
     报错：“./autogen.sh: line 5: libtoolize: command not found”
     
     安装 libtool。运行命令：brew install libtool
     
     继续运行命令：./autogen.sh
     
     报错“./autogen.sh: line 5: libtoolize: command not found”
     
     通过这篇文章：http://*.com/questions/15448582/installed-libtool-but-libtoolize-not-found
     
     我是在改动./autogen.sh 把第五行改成 glibtoolize --copy
     
     网上也有这样改得（我没试）:

case `uname` in Darwin*) glibtoolize --copy ;;

  *) libtoolize --copy ;; esac 

运行命令：./autogen.sh

报错：“configure.ac:42: error: possibly undefined macro: AC_DEFINE

If this token and others are legitimate, please use m4_pattern_allow.

See the Autoconf documentation.

configure.ac:44: error: possibly undefined macro: AC_MSG_FAILURE”

通过这篇文章http://*.com/questions/8811381/possibly-undefined-macro-ac-msg-error

我安装了pkgconfig，运行命令：brew install pkgconfig

报错“rm: autom4te.cache/output.0: Permission denied

rm: autom4te.cache/output.1: Permission denied

rm: autom4te.cache/requests: Permission denied

rm: autom4te.cache/traces.0: Permission denied

rm: autom4te.cache/traces.1: Permission denied

rm: autom4te.cache: Directory not empty

”

改成sudo ,运行命令：sudo ./autogen.sh

- 运行configure ,运行命令：./configure

- 运行make。运行命令：make

- 运行make install，运行命令：make install
