i am trying to compile my program which uses regex on linux. I built the boost library in the
libs/regex/build
by typing
make -fgcc.mak
which created a directory gcc which contains the following four files
boost_regex-gcc-1_35
boost_regex-gcc-d-1_35
libboost_regex-gcc-1_35.a
libboost_regex-gcc-d-1_35.a
Now I want to use regex from my program which is in some arbitrary directory.
I #included boost/regex.hpp
I got the error which stated that regex.hpp is not found. Then I gave the -I option in the g++ compiler. I didn't get that error.
But I get the following error
undefined reference to `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> > >::construct_init(boost::basic_regex<char, boost::regex_traits<char, boost::cpp_regex_traits<char> > > const&, boost::regex_constants::_match_flags)'
I googled and found that I need to somehow link one of the above 4 libraries to my program. How can I do it. Which one should I link and why?
