  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.

 405 dnl Optimization hacks: compiling C++ is slow, especially with Boost.  What
 406 dnl we're trying to do here is guess the right combination of link flags
 407 dnl (LIBS / LDFLAGS) to use a given library.  This can take several
 408 dnl iterations before it succeeds and is thus *very* slow.  So what we do
 409 dnl instead is that we compile the code first (and thus get an object file,
 410 dnl typically conftest.o).  Then we try various combinations of link flags
 411 dnl until we succeed to link conftest.o in an executable.  The problem is
 412 dnl that the various TRY_LINK / COMPILE_IFELSE macros of Autoconf always
 413 dnl remove all the temporary files including conftest.o.  So the trick here
 414 dnl is to temporarily change the value of ac_objext so that conftest.o is
 415 dnl preserved accross tests.  This is obviously fragile and I will burn in
 416 dnl hell for not respecting Autoconf's documented interfaces, but in the
 417 dnl mean time, it optimizes the macro by a factor of 5 to 30.
 418 dnl Another small optimization: the first argument of AC_COMPILE_IFELSE left
 419 dnl empty because the test file is generated only once above (before we
 420 dnl start the for loops).
