# 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
