Hi everybody. I'm a new user of boost c++. I tried to install it on my Mac. I followed "Getting Started on Unix variant" guide which I found on boost.org site. The first part is ok, I tried to compile and execute the simple example and i had no problem, it runs. After it I tried to build and install the separately-compiled Boost libraries, I copied the example in my editor and I typed on terminal: c++ -I /Users/Simone/Documents/workspace/boost_1_49_0 main.cpp -o main\ ~/boost/stage/lib/libboost_regex-darwin-mt-d-1_49_0.a but the result was: Undefined symbols: "boost::re_detail::get_mem_block()", referenced from: 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> > >::extend_stack()in ccmv1in1.o "boost::match_results<__gnu_cxx::__normal_iterator<char const*, std::basic_string<char, std::char_traits<char>, std::allocator<char> >

Even if I used the other way to compile, ("separately specify a directory to search (with -Ldirectory)"), the result is always the same. What can I do?? Thank You Simone
