Comment (by shaohua199@…):

 Hi,

 This problem is resolved.

 After I use "nm -gC libboost_regex.so" command to check my library, I find
 the
 0000000000051370 W
 boost::re_detail_106000::perl_matcher<boost::re_detail_106000::mapfile_iterator,
 '''stl'''::allocator<boost::sub_match<boost::re_detail_106000::mapfile_iterator>
 >, boost::regex_traits<char, boost::cpp_regex_traits<char> >
 >::construct_init(boost::basic_regex<char, boost::regex_traits<char,
 boost::cpp_regex_traits<char> > > const&,
 boost::regex_constants::_match_flags)

 And my link error is:
 error: undefined reference to 'boost::re_detail_106000::perl_matcher<char
 const*, '''stlp_std'''::allocator<boost::sub_match<char const*> >,
 boost::regex_traits<char, boost::cpp_regex_traits<char> >
 >::construct_init(boost::basic_regex<char, boost::regex_traits<char,
 boost::cpp_regex_traits<char> > > const&,
 boost::regex_constants::_match_flags)'

 So it is caused by my application use stlport library. After I re-compile
 boost library with "stdlib=stlport" option and specified "using stlport"
 in  project-config.jam file, the link process is OK now.

 Thanks very much for your help.

 Thanks,
 Shaohua
