使用REGEX库构建VC ++代码时链接器错误 [英] Linker errors while building VC++ code with REGEX library

问题描述

我正在尝试执行以下程序。它构建正常，但是我遇到了2个链接器错误：

请帮助我。

 ＃ include   <   iostream  >  
   #include   <   iterator  >  
   #include   <   regex  >  
   #include   <   string  > ;  
   //   #define BOOST_REGEX_DYN_LINK  
 
 使用 命名空间性病; 
 
  int  main（）
 {
 std :: string text =  快速棕狐; 
 std :: regex vowel_re1（  a | e | i | o | u） ; 
 
 
  //  将结果写入输出迭代器 
 std :: regex_replace（std :: ostreambuf_iterator< char>（std :: cout），
 text.begin（），text.end（），vowel_re1，   *）; 
 
  //  构造一个包含结果的字符串 
 std： ：cout<< '  \ n'<< std :: regex_replace（text，vowel_re1，  [$&]）<< '  \ n'; 
}

Hi,

I am trying to execute below program. It is building fine but am getting 2 linker errors:
Kindly help me.

#include <iostream>
#include <iterator>
#include <regex>
#include <string>
//#define BOOST_REGEX_DYN_LINK

using namespace std;
 
int main()
{
   std::string text = "Quick brown fox";
   std::regex vowel_re1("a|e|i|o|u");

 
   // write the results to an output iterator
   std::regex_replace(std::ostreambuf_iterator<char>(std::cout),
                      text.begin(), text.end(), vowel_re1, "*");
 
   // construct a string holding the results
   std::cout << '\n' << std::regex_replace(text, vowel_re1, "[$&]") << '\n';
}
