Hi all, I'm a newbie in c++ and in boost too, but i want to learn ;) I've installed boost via apt and also with "hand-compile" but it doesn't run anyway.. here my code: -------------------- #include <iostream> #include <boost/regex.hpp> using namespace boost; using namespace std; int main() { const boost::regex e("PING\\s:\\S+"); cmatch match; if(boost::regex_match("PING :jgWEjg",match,e)) { cout << "PONG :" << match[1]; } return 0; } -------------------- then i want to compile it with ""g++ main.cc -o test" and these errors appeared: -------------------- /tmp/ccb8hTb3.o(.gnu.linkonce.t._ZN5boost11basic_regexIcNS_12regex_traitsIcEESaIcEED1Ev+0xd): In function `boost::basic_regex<char, boost::regex_traits<char>, std::allocator<char> >::~basic_regex [in-charge]()': : undefined reference to `boost::reg_expression<char, boost::regex_traits<char>, std::allocator<char> >::~reg_expression [not-in-charge]()' /tmp/ccb8hTb3.o(.gnu.linkonce.t._ZN5boost11basic_regexIcNS_12regex_traitsIcEESaIcEEC1EPKcjRKS3_+0x22): In function `boost::basic_regex<char, boost::regex_traits<char>, std::allocator<char> >::basic_regex[in-charge](char const*, unsigned, std::allocator<char> const&)': : undefined reference to `boost::reg_expression<char, boost::regex_traits<char>, std::allocator<char>
