boost是c++下的强大的library库，本文讲一下怎么安装boost的正则表达式模块。

1：下载boost源文件。

wget http://cdnetworks-kr-1.dl.sourceforge.net/project/boost/boost/1.42.0/boost_1_42_0.tar.gz

解包后进入到根目录。

2：./bootstrap.sh --with-libraries=regex --prefix=/usr/local/regex

./bjam install现在回在/usr/local/regex下生成动态和静态的链接库。3：实例验证

#include <iostream>#include <string>#include <boost/regex.hpp>  // Boost.Regex libusing namespace std;int main( ) {   std::string s, sre;   boost::regex re;   while(true)   {      cout << "expression_r: ";      cin >> sre;      if (sre == "quit")      {         break;      }      cout << "String:     ";      cin >> s;      try      {         // Set up the regular expression_r for case-insensitivity         re.assign(sre, boost::regex_constants::icase);      }      catch (boost::regex_error& e)      {         cout << sre << " is not a valid regular expression_r: \""              << e.what() << "\"" << endl;         continue;      }      if (boost::regex_match(s, re))      {         cout << re << " matches " << s << endl;      }   }}

4：编译g++  -I  boostlib/  rtest.cpp -o rtest /usr/local/regex/lib/libboost_regex.a建议用静态链接库，不然的话你还得再运行的机器上再单独安装boost的regex模块。参考：http://onlamp.com/pub/a/onlamp/2006/04/06/boostregex.html?page=1      http://www.boost.org/doc/libs/1_42_0/more/getting_started/unix-variants.html
