5 # SYNOPSIS
7 #   AX_BOOST_BASE([MINIMUM-VERSION], [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])
9 # DESCRIPTION
11 #   Test for the Boost C++ libraries of a particular version (or newer)
13 #   If no path to the installed boost library is given the macro searchs
14 #   under /usr, /usr/local, /opt and /opt/local and evaluates the
15 #   $BOOST_ROOT environment variable. Further documentation is available at
16 #   <http://randspringer.de/boost/index.html>.
18 #   This macro calls:
20 #     AC_SUBST(BOOST_CPPFLAGS) / AC_SUBST(BOOST_LDFLAGS)
22 #   And sets:
24 #     HAVE_BOOST
