Boost 1.39使用笔记
Boost大部分还是以code的形势提供给用户使用的，但是涉及的三个库ICU、EXPAT、MPI是分别在实现regex、graph和mpi的时候所依赖的。先介绍Linux环境下的编译过程。
Easy Build and Install
在官方的帮助手册里会给你写着这么一段安装的介绍：Easy Build and Install
Issue the following commands in the shell (don't type $; that represents the shell's prompt):
$ cd path/to/boost_1_39_0
$ ./bootstrap.sh --help
Select your configuration options and invoke ./bootstrap.sh again without the --help option. Unless you have write permission in your system's /usr/local/ directory, you'll probably want to at least use
$ ./bootstrap.sh --prefix=path/to/installation/prefix
to install somewhere else. Also, consider using the --show-libraries and --with-libraries= options to limit the long wait you'll experience if you build everything. Finally,
$ ./bjam install
will leave Boost binaries in the lib/ subdirectory of your installation prefix. You will also find a copy of the Boost headers in the include/ subdirectory of the installation prefix, so you can henceforth use that directory as an #include path in place of the Boost root directory.
看到了么，生成了一个bjam，你可以把这个bjam拷贝到boost的解压目录里。是相当简单的Easy Build and install。
更为完备的编译参数配置
显然这样的编译设置我们是不能满足的，如果你希望能够拥有一个功能完备boost库来使用的参数的话，你就需要做一下参数的调整。
在解压目录中存在tools/build/v2/user-config.jam文件，该文件是专门配置变异参数的用户定义的配置文件。我们的编译器用的是gcc然后就把using gcc ;参数打开，在最后增加一个参数using mpi ;。增加此参数是为了生成MPI模块使用的。
第三方类库的准备
mpic++的支持
由于要生成MPI模块这里要依赖OpenMPI,可以参考一下下边连接中的一段内容：（http://www.nabble.com/MPI-auto-detection-failed:-unknown-wrapper-compiler-mpic%2B%2B-td23090203.html）
First, you need to install the package "openmpi-devel". Do this as root:
# yum install openmpi-devel
This should bring in a number of dependencies, including a package named
"mpi-selector". Once the installation has finished, done, use the MPI selector
tool to choose the MPI toolset you've just installed. You can get a list
of available MPI implementations using the command "mpi-selector". As an
example, here's how it looks on my 64-bit CentOS 5.3 system:
# mpi-selector --list
openmpi-1.2.7-gcc-i386
openmpi-1.2.7-gcc-x86_64
Then, while still logged in as root, set the system-wide default by
# mpi-selector --system openmpi-1.2.7-gcc-x86_64
Log out, then open a new terminal window (as your normal user) and try
$ which mpic++
/usr/lib64/openmpi/1.2.7-gcc/bin/mpic++
安装expat
yum install expat*
安装ICU
可编译安装也可以用yum安装
设置环境变量，编译安装
export ICU_PATH=/usr/include<icu_include_path>
export EXPAT_INCLUDE=/usr/include<expat_include_path>
export EXPAT_LIBPATH=/usr/lib<expat_lib_path>
./bjam install
至此，结束
