[Boost-users] Boost regex does't work

Hi, I'm a new user of boost. I have a trouble to use boost. I downloaded boost_1_36_0 and put it on directory where I prefer. To use with eclipse, I set the path. Property->c/c++build->settings->GCC C++ compiler->directories Some functions like boost/tokenizer or boost/lexical_cast is working well, but only the function boost/regex doesn't work. Compile is finished safely, but once I tried to run, an error is appear ,and the process stops. Undefined symbols: "boost::basic_regex >::do_assign(char const*, char const*, unsigned int)", referenced from: boost::basic_regex >::assign(char const*, char const*, unsigned int)in main.o ld: symbol(s) not found collect2: ld returned 1 exit status Would someone have ideas to use boost/regex on eclipse? My plattform is Mac OSX Leopard. Thanks,
