windows下使用boost编译levelBD小记。

使用boost编译leveldb的好处是xp下能用，本博客上一篇文章编译出来的因为不是使用google官方代码，编译出来不支持xp。

本次使用官方源，windows分支，xp运行通过。

一）。下载boost ：

http://iweb.dl.sourceforge.net/project/boost/boost/1.52.0/boost_1_52_0.tar.bz2

50多M，解压后先运行一个bootstrap.bat, 再按提示运行b2.exe, 不想全编译的可以看b2.exe的帮助

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，编译了20分钟左右。

以上命令是编译并安装好，默认安装目录是 C:\Boost

threading=multi 是必需的，好像默认使用单线程，vs不能链接过。

msvc-9.0是使用vs2008编译， 注意把vs2008的tools目录加到环境变量中。

然后再按提示把相关头文件目录与静态库目录加到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\lib

二）然后 就是去levelDB下载 源码，具体的编译流程，官网的windows分支有说明：

https://code.google.com/p/leveldb/source/browse/WINDOWS?name=windows

下载选择windows分支，一开始没留意到这个分支选择，下载了几次都没有port_win.h等相关文件,

此分支主要是有以下几个文件：

port/port_win.h
port/port_win.cc
util/env_boost.h
util/win_logger.cc
util/win_logger.h

然后 修改port/port.h文件。这步是上面那个说明没提到的：

#ifndef STORAGE_LEVELDB_PORT_PORT_H_
#define STORAGE_LEVELDB_PORT_PORT_H_

#include <string.h>

// Include the appropriate platform specific file below.  If you are
// porting to a new platform, see "port_example.h" for documentation
// of what the new port_<platform>.h file must provide.
#if defined(LEVELDB_PLATFORM_POSIX)
#  include "port/port_posix.h"
#elif defined(LEVELDB_PLATFORM_CHROMIUM)
#  include "port/port_chromium.h"
#elif defined(LEVELDB_PLATFORM_ANDROID)
#  include "port/port_android.h"
#elif defined(LEVELDB_PLATFORM_WINDOWS)  // 主要添加此宏与
#  include "port/port_win.h"   // 幷包含此头文件
#endif#endif // STORAGE_LEVELDB_PORT_PORT_H_

最后比较重要的一步，把port/win/stdint.h文件删除 或改名。

原因在：http://www.ogre3d.org/forums/viewtopic.php?f=2&t=70414 拉到最后看发帖者的回答。

其实就boost包含stdin.h文件，而工程中又有一个同名的，被先包含了，造成以下错：
