First of all, I just made a mistake to post the message in gun.gcc.help... So I re-post it here. I think it will not off-topic now:-)
Below is a description about the problem: Today, I downloaded the lastest version of boost. And compiled it with my minGW(the version of g++ is 3.4.2). The compile command I used is "bjam -sTOOLS=mingw --prefix=D:\3rd\boost install ". So all the compiled .libs and the header files are placed in D:\3rd\boost. And I set environment variant CPLUS_INCLUDE_PATH=d:\3rd\boost\include\boost-1_34. Then I wrote two short programs to test the new built boost. The first was to test boost::shared_ptr, because shared_ptr refer no .lib, so it passed the compilation. The second is to test boost::regex. it need a link of some boost .lib. But g++ report a link error when compiling. I used "g++ rx.cpp -L D:\3rd\boost\lib -o rx" to generate the .exe. The compile 's error message is: E:\DOCUME~1\ddh\LOCALS~1\Temp/ccCebaaa.o(.text$_ZN5boost11regex_matchIN9__gnu_cx x17__normal_iteratorIPKcSsEESaINS_9sub_matchIS5_EEEcNS_12regex_traitsIcNS_16cpp_ regex_traitsIcEEEEEEbT_SD_RNS_13match_resultsISD_T0_EERKNS_11basic_regexIT1_T2_E ENS_15regex_constants12_match_flagsE[bool boost::regex_match<__gnu_cxx::__normal _iterator<char const*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > >, std::allocator<boost::sub_match<__gnu_cxx::__normal_iterator<ch ar const*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > > > >, char, boost::regex_traits<char, boost::cpp_regex_traits<char> > > > > >>(__gnu_cxx::__normal_iterator<char const*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > >, __gnu_cxx::__normal_iterator<char const*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > >, boost::match_results<__gnu_cxx::__normal_iterator<char const*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > >, std::allocator<boost::sub_match<__gnu_cxx::__normal_iterator<char const*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > > > > >&, boost::basic_regex<char, boost::regex_traits<char, boost::cpp_regex_traits<char> > > const&, boost::regex_constants::_match_flags)]+0x9a):rx.cpp: undefined reference to `boost::re_detail::perl_matcher<__gnu_cxx::__normal_iterator<char const*, std::string>, std::allocator<boost::sub_match<__gnu_cxx::__normal_iterator<char const*, std::string> > >, boost::regex_traits<char, boost::cpp_regex_traits<char> > >::match()' E:\DOCUME~1\ddh\LOCALS~1\Temp/ccCebaaa.o(.text$_ZN5boost11basic_regexIcNS_12rege x_traitsIcNS_16cpp_regex_traitsIcEEEEE6assignEPKcS7_j[boost::basic_regex<char, boost::regex_traits<char, boost::cpp_regex_traits<char> > >::assign(char const*, char const*, unsigned int)]+0x22):rx.cpp: undefined >reference to `boost::basic_regex<char, boost::regex_traits<char, >boost::cpp_regex_traits<char> >>::do_assig n(char const*, char const*, unsigned int)' E:\DOCUME~1\ddh\LOCALS~1\Temp/ccCebaaa.o(.text$_ZN5boost9re_detail12perl_matcher IN9__gnu_cxx17__normal_iteratorIPKcSsEESaINS_9sub_matchIS6_EEENS_12regex_traitsI cNS_16cpp_regex_traitsIcEEEEEC1ES6_S6_RNS_13match_resultsIS6_S9_EERKNS_11basic_r egexIcSD_EENS_15regex_constants12_match_flagsES6_[boost::re_detail::perl_matcher <__gnu_cxx::__normal_iterator<char const*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > >, std::allocator<boost::sub_match<__gnu_cxx::__normal_iterator<char const*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > > > >, boost::regex_traits<char, boost::cpp_regex_traits<char> > >::perl_matcher(__gnu_cxx::__normal_iterator<char const*, >std::basic_string<char, std::char_traits<char>, std::allocator<char> > >, __gnu_cxx::__normal_iterator<char const*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > >, boost::match_results<__gnu_cxx::__normal_iterator<char const*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > >, std::allocator<boost::sub_match<__gnu_cxx::__normal_iterator<char const*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > > > > >&, boost::basic_regex<char, boost::regex_traits<char, boost::cpp_regex_traits<char> > > const&,boost::regex_constants::_match_flags, __gnu_cxx::__normal_iterator<char const*,std::basic_string<char, std::char_traits<char>, std::allocator<char> >>)]+0x110):rx.cpp: undefined reference to `boost::re_detail::perl_matcher<__gnu_cxx::__normal_iterator<char const*, std::string>, std::allocator<boost::sub_match<__gnu_cxx::__normal_iterator<char const*, std::string> > >,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_const >>ants::_match_flags)' collect2: ld returned 1 exit status I think the problem is that g++ didn't know which .lib it should used to generate the .exe file. But how to set it ? I don't want to add the proper .lib name in the compile command everytimes. Thank you very much for your help ! _______________________________________________ Help-gplusplus mailing list Help-gplusplus@gnu.org http://lists.gnu.org/mailman/listinfo/help-gplusplus
