| # 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 |
| # <https://www.randspringer.de/boost/index.html>. |
| # |
| # This macro calls: |
| # |
| # AC_SUBST(BOOST_REGEX_LIB) |
| # |
| # And sets: |
| # |
| # HAVE_BOOST_REGEX |
