How do I compile a program that uses the libregex program? It seems that whenever I do this: $ gcc -o te1 te1.cc -lboost_regex I get: ---- /tmp/cc9r42Gv.o: In function `boost::reg_expression::fail(unsigned int)': /tmp/cc9r42Gv.o(.boost::reg_expression

::gnu.linkonce.t.fail(unsigned int)+0x4e): undefined reference to `boost::bad_expression::bad_expression(basic_string > const &)' /tmp/cc9r42Gv.o: In function `boost::reg_expression >, allocator<char> > &, boost::re_detail::jstack >, allocator<char> > &, boost::re_detail::jstack &, boost::re_detail::jstack >, allocator<char> > &, bool, boost::re_detail::_narrow_type const &)': . . .

Here is the source to te1.cc ---- #include <iostream> #include <string> #include using namespace boost; int main(int argc, char *argv[]) { cmatch what; string str = "XXyX"; regex expression("(\\S\\S){[Ayw]}(\\S)/"); if(regex_match(str,what,expression)) { cout << "what" << endl; } else { cout << "Shit\n"; } return 0; } -------- What am I doing wrong?
