5 # SYNOPSIS

7 # AX_BOOST_BASE([MINIMUM-VERSION], [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])
8 #
9 # DESCRIPTION
10 #
11 # Test for the Boost C++ libraries of a particular version (or newer)
12 #
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>.
17 #
18 # This macro calls:
19 #
20 # AC_SUBST(BOOST_CPPFLAGS) / AC_SUBST(BOOST_LDFLAGS)
21 #
22 # And sets:
23 #
24 # HAVE_BOOST
