| # 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 | ||
