boost 1_43_0 在arm-linux下编译

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"
