# This file provides several macros to use the various Boost libraries.
# The first macro is BOOST_REQUIRE. It will simply check if it's possible to
# find the Boost headers of a given (optional) minimum version and it will
# define BOOST_CPPFLAGS accordingly. It will add an option --with-boost to
# your configure so that users can specify non standard locations.
# If the user's environment contains BOOST_ROOT and --with-boost was not
# specified, --with-boost=$BOOST_ROOT is implicitly used.
# For more README and documentation, go to http://github.com/tsuna/boost.m4
# Note: THESE MACROS ASSUME THAT YOU USE LIBTOOL. If you don't, don't worry,
# simply read the README, it will show you what to do step by step.

dnl we're trying to do here is guess the right combination of link flags
dnl (LIBS / LDFLAGS) to use a given library. This can take several
dnl iterations before it succeeds and is thus *very* slow. So what we do
dnl instead is that we compile the code first (and thus get an object file,
dnl typically conftest.o). Then we try various combinations of link flags
dnl until we succeed to link conftest.o in an executable. The problem is
dnl that the various TRY_LINK / COMPILE_IFELSE macros of Autoconf always
dnl remove all the temporary files including conftest.o. So the trick here
dnl is to temporarily change the value of ac_objext so that conftest.o is
dnl preserved accross tests. This is obviously fragile and I will burn in
dnl hell for not respecting Autoconf's documented interfaces, but in the
dnl mean time, it optimizes the macro by a factor of 5 to 30.
