Linux 编译安装Boost

linux平台下要编译安装除gcc和gcc-c++之外，还需要两个开发库：bzip2-devel 和python-devel，因此在安装前应该先保证这两个库已经安装：

#yum install gcc gcc-c++ bzip2 bzip2-devel bzip2-libs python-devel -y

然后是去官网下载源码包，地址
下载，解压，按照如下步骤：

#tar xvzf boost_1_50_0.tar.gz

进入boost_1_50_0目录：

#cd boost_1_50_0

然后是编译安装，boost源码包中有配置脚本，直接用就可以：

#sh ./bootstrap.sh

Building Boost.Build engine with toolset gcc... tools/build/v2/engine/bin.linuxx86_64/b2
Detecting Python version... 2.6
Detecting Python root... /usr
Unicode/ICU support for Boost.Regex?... not found.
Generating Boost.Build configuration in project-config.jam...

Bootstrapping is done. To build, run:

./b2
   
To adjust
configuration, edit 'project-config.jam'.
Further information:

- Command line help:
     ./b2 --help
    
   - Getting started guide:
     http://www.boost.org/more/getting_started/unix-variants.html
    
   - Boost.Build documentation:
     http://www.boost.org/boost-build2/doc/html/index.html

接下来就是编译，重点关注是否编译成功：

#./b2

然后就是漫长的等待，如果最后出现：

The Boost C++ Libraries were
successfully built!
         
The following
directory should be added to compiler include paths:
          
    /home/gang/BAK/boost_1_50_0
     
The following
directory should be added to linker library paths:
     
    /home/gang/BAK/boost_1_50_0/stage/lib

表示编译成功，如果没有成功，就需要回查看哪里出现error，再安装相应的库，
最后就是安装：

#./b2 install --prefix=/usr/local

安装后的头文件在/usr/local/include/boost里面，而相应的库在/usr/local/lib/libboost_*
