After downloading boost_1_33_1, I succeeded in building regex lib with both VC8 and GCC 3.4.2(mingw special) 1st: The following code, which is compiled ok using VC8 (cl a.cpp/I"F:\boost_1_33_1" /EHsc), gives out wrong answer. Well I think the answer is wrong. Do I misunderstand the regular expression? It says"no match" while it is supposed to match twice. 01234 and 56972. If I changes the regex expr to ".*", the code functions well and gives out: The (0) match is:01234abcd56972 //==================CODE================ #include <string> #include #include <iostream> using namespace std; using namespace boost; regex expr("([0-9]+)"); const char *src = "01234abcd56972"; int main(int argc, char *argv[]) { cmatch m; if(regex_match(src, m, expr)) { for(int i = 0; i < m.size(); ++i) { string msg; msg.assign(m[i].first, m[i].second); cout<<"The ("<< i <<") match is:"< g++ a.cpp -I"F:\boost_1_33_1" -o a.exe C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp/cccPaaaa.o(.text$_ZN5boost11regex_matchIPKcSa INS_9sub_matchIS2_EEEcNS_12regex_traitsIcNS_16cpp_regex_traitsIcEEEEEEbT_SA_RNS_ 13match_resultsISA_T0_EERKNS_11basic_regexIT1_T2_EENS_15regex_constants12_match_ flagsE[bool boost::regex_match >, char, boost::regex_traits

Can some help me? Although I know the question above may seem stupid and easy to solve. //Thanks -- This is my Very Signature. Ha, pretty good?
