| # SYNOPSIS | ||
| # | ||
| # AX_BOOST_REGEX | ||
| # | ||
| # DESCRIPTION | ||
| # | ||
| # Test for Regex library from the Boost C++ libraries. The macro requires | ||
| # a preceding call to AX_BOOST_BASE. Further documentation is available at | ||
| # <http://randspringer.de/boost/index.html>. | ||
| # | ||
| # This macro calls: | ||
| # | ||
| # AC_SUBST(BOOST_REGEX_LIB) | ||
| # | ||
| # And sets: | ||
| # | ||
| # HAVE_BOOST_REGEX | ||
