android 编译boost动态库
有个android项目上需要使用到boost标准c++库,Boost库是一个可移植、提供源代码的C++库，作为标准库的后备，是C++标准化进程的发动机之一，所以想将其移植到android系统上进行编译。直接从网上下载 boost1.52版本，然后写makefile。。。进行编译，，碰到无数的编译错误。求助于google网络，终于发现一个好东东：
一个通过NDK编译boost代码的git项目：
https://github.com/MysticTreeGames/Boost-for-Android
这里是使用NDK进行编译boost的但肯定对我有用吧。。经过一番折腾终于编译成功，，高兴,呵呵！
下面将主要的过程记录下来：
1、下载boost 源码：
Boost for Android
Boost for android is a set of tools to compile the main part of the Boost C++ Libraries for the Android platform.
Currently supported boost versions are 1.45.0, 1.48.0 and 1.49.0.
因此下载最新的 1.49 版本，下载完成后进行打补丁
2、下载补丁代码
https://github.com/MysticTreeGames/Boost-for-Android/tree/master/patches/boost-1_49_0
3、打补丁代码
boost_1_49_0.tar.bz2 放在android的 external 下解压：
tar -xjvf external/boost_1_49_0.tar.bz2
将boost-1_49_0.patch放在external\boost_1_49_0下面根目录执行：
patch -Np1 -d external/boost_1_49_0 < external/boost_1_49_0/boost-1_49_0.patch
4、编写boost的makefile文件，即Android.mk

最后编译生成：
target thumb C++: libboost <= external/boost_1_49_0/libs/thread/src/pthread/thread.cpp
target thumb C++: libboost <= external/boost_1_49_0/libs/thread/src/pthread/once.cpp
