下载
1 boost_1_43_0.tar.gz
2 tar -zxvf boost_1_43_0.tar.gz
3 设置环境变量
export PATH=$PATH:/opt/timesys/toolchains/armv5l-linux/bin/
3. 进入目录执行./bootstrap.sh， 此时形成bjam文件和project-config.jam
4. 编辑project-config.jam， 仅修改using gcc这行。因为我使用的是arm-linux-gcc,所以将其改以下即可：
using gcc : : arm51v-linux-gcc ;
5. 执行./bjam stage，编译asio
./bjam --with-system --with-thread --with-date_time --with-regex --with-serialization stage
6. 形成的静态和动态库文件就在stage目录下.
如果全部编译会如下：
- chrono : building
- date_time : building
- exception : building
- filesystem : building
- graph : building
- graph_parallel : building
- iostreams : building
- locale : building
- math : building
- mpi : building
- program_options : building
- python : not building
- random : building
- regex : building
- serialization : building
- signals : building
- system : building
- test : building
- thread : building
- timer : building
- wave : building
7 使用：
vi boost_test.cpp 敲入串口代码
编译：
arm-linux-g++ -g boost_test.cpp -I/home/neo/tools/boost-1.4 -L/home/neo/tools/boost-1.4/stage/lib/ -lboost_system -lboost_thread -lboost_chrono -lboost_wserialization -lpthread
/home/neo/tools/boost-1.4
在PC Linux上执行命令：arm-linux-readelf -a "your binary" | grep "Shared"
