linux下编译boost_1_46_1

操作系统：centos-5.6

如果要使用boost的graph库，必须先安装icu库（icu4c-4_0-src.gz）

1、解压 tar zxvf boost_1_46_1.tar.gz

（我的当前目录为/root）

2、编译和安装，先切换到目录boost_1_46_1

./bootstrap.sh
./bjam
./bjam install

3、设置环境变量：

BOOST_ROOT=/root/boost_1_46_1
BOOST_INCLUDE=/usr/local/include/boost
BOOST_LIB=/usr/local/lib
export BOOST_ROOT BOOST_INCLUDE BOOST_LIB

4、测试：

//regex.cpp

#include <boost/regex.hpp>
#include <iostream>
#include <string>

int main()
{
    std::string line;
    boost::regex pat( "^Subject: (Re: |Aw: )*(.*)" );

    while (std::cin)
    {
        std::getline(std::cin, line);
        boost::smatch matches;
        if (boost::regex_match(line, matches, pat))
            std::cout << matches[2] << std::endl;
    }
}

编译：g++ -g -I$BOOST_INCLUDE -L$BOOST_LIB -o regex regex.cpp -lboost_regex

执行：./regex

5、如果执行./regex时报错

./regex: error while loading shared libraries: libboost_regex.so.1.46.1: cannot open shared object file: No such file or directory

编辑/etc/ld.so.conf

加入库路径 /usr/local/lib
