# 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 |
