# 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 |
