[Boost-users] Linker errors with boost::regex with boost_1_33_1, STLport-4.6.2 and VS7.1

Hi All,
Is there a known issue of linker errors with using boost::regex library
with STLport.

If I don't install STLport I am able to build regex however I am getting
linker error while trying to build after installing STLPort.
 

Operating System:Win-XP
IDE: Visual Studio .NET(version 7.1.3088)
STLPort version: STLport-4.6.2
Boost versio:boost_1_33_1

The code which I have used in sample project:

#include "stdafx.h"
#include <boost/regex.hpp>
#include <iostream>
#include <string>

int _tmain(int argc, _TCHAR* argv[])
{
  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];
  }
  return 0;
}

I got following linker errors:
ConsoleApp1.obj : error LNK2019: unresolved external symbol "void
__cdecl boost::re_detail::raise_runtime_error(class _STL::runtime_error
const &)"
(?raise_runtime_error_at_re_detail_at_boost@@YAXABVruntime_error@_STL@@@Z)

Debug/ConsoleApp1.exe : fatal error LNK1120: 2 unresolved externals

However if I comment call to function boost::regex_match() in sample
code , then I am able to build it.
