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

341dnl Optimization hacks: compiling C++ is slow, especially with Boost. What
342dnl we're trying to do here is guess the right combination of link flags
343dnl (LIBS / LDFLAGS) to use a given library. This can take several
344dnl iterations before it succeeds and is thus *very* slow. So what we do
345dnl instead is that we compile the code first (and thus get an object file,
346dnl typically conftest.o). Then we try various combinations of link flags
347dnl until we succeed to link conftest.o in an executable. The problem is
348dnl that the various TRY_LINK / COMPILE_IFELSE macros of Autoconf always
349dnl remove all the temporary files including conftest.o. So the trick here
350dnl is to temporarily change the value of ac_objext so that conftest.o is
351dnl preserved accross tests. This is obviously fragile and I will burn in
352dnl hell for not respecting Autoconf's documented interfaces, but in the
353dnl mean time, it optimizes the macro by a factor of 5 to 30.
