# SYNOPSIS
|
|
#
|
|
# AX_BOOST_BASE([MINIMUM-VERSION])
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# Test for the Boost C++ libraries of a particular version (or newer)
|
|
#
|
|
# If no path to the installed boost library is given the macro searchs
|
|
# under /usr, /usr/local, /opt and /opt/local and evaluates the
|
|
# $BOOST_ROOT environment variable. Further documentation is available at
|
|
# <http://randspringer.de/boost/index.html>.
|
|
#
|
|
# This macro calls:
|
|
#
|
|
# AC_SUBST(BOOST_CPPFLAGS) / AC_SUBST(BOOST_LDFLAGS)
|
|
#
|
|
# And sets:
|
|
#
|
|
# HAVE_BOOST
|
|
