# =========================================================================== # https://www.gnu.org/software/autoconf-archive/ax_boost_base.html # =========================================================================== # # SYNOPSIS # # AX_BOOST_BASE([MINIMUM-VERSION], [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND]) # # 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 # # LICENSE # # Copyright (c) 2008 Thomas Porschberg <thomas@randspringer.de> # Copyright (c) 2009 Peter Adolphs # # Copying and distribution of this file, with or without modification, are # permitted in any medium without royalty provided the copyright notice # and this notice are preserved.
