Enabling capture information has an impact on performance, so you must
define BOOST_REGEX_MATCH_EXTRA *both* in your code, and when you are
building the regex library. If you just want to build the example program
then the easiest way is to use bjam to do so: cd into libs/regex/example
Alternatively add #define BOOST_REGEX_MATCH_EXTRA to boost/regex/user.hpp
and rebuild the library.
This is all documented here:
