使用boost編譯leveldb的好處是xp下能用，本博客上一篇文章編譯出來的因爲不是使用google官方代碼，編譯出來不支持xp。
本次使用官方源，windows分支，xp運行通過。
一）。下載boost ：
http://iweb.dl.sourceforge.net/project/boost/boost/1.52.0/boost_1_52_0.tar.bz2
50多M，解壓後先運行一個bootstrap.bat, 再按提示運行b2.exe, 不想全編譯的可以看b2.exe的幫助
bootstrap.bat
D:\src\boost_1_52_0>bjam install --toolset=msvc-9.0 link=static runtime-link=static threading=multi release address-model=32 --with-date_time --with-filesystem --with-thread --with-chrono
我I5上，編譯了20分鐘左右。
以上命令是編譯並安裝好，默認安裝目錄是 C:\Boost
threading=multi 是必需的，好像默認使用單線程，vs不能鏈接過。
msvc-9.0是使用vs2008編譯， 注意把vs2008的tools目錄加到環境變量中。
然後再按提示把相關頭文件目錄與靜態庫目錄加到vs中：
The Boost C++ Libraries were successfully built!
The following directory should be added to compiler include paths:
C:\Boost\include\boost-1_52
The following directory should be added to linker library paths:
C:\Boost\libhttps://code.google.com/p/leveldb/source/browse/WINDOWS?name=windows
下載選擇windows分支，一開始沒留意到這個分支選擇，下載了幾次都沒有port_win.h等相關文件,
此分支主要是有以下幾個文件：
port/port_win.h
port/port_win.cc
util/env_boost.h
util/win_logger.cc
util/win_logger.h然後 修改port/port.h文件。這步是上面那個說明沒提到的：

其實就boost包含stdin.h文件，而工程中又有一個同名的，被先包含了，造成以下錯：
