### CHANGES BY VINCE FOR LSMGENGEO

34

# (copied from Cihan's changes to ESyS-Particle: (grep/search for LSMGENGEO)

35

# * changed order of search directories for libraries - /usr/lib is now first

36

# * always link boost_system with boost_filesystem for newer boost versions,

37

# not only when linking static libraries.

43

# This file provides several macros to use the various Boost libraries.

44

# The first macro is BOOST_REQUIRE. It will simply check if it's possible to

45

# find the Boost headers of a given (optional) minimum version and it will

46

# define BOOST_CPPFLAGS accordingly. It will add an option --with-boost to

47

# your configure so that users can specify non standard locations.

48

# If the user's environment contains BOOST_ROOT and --with-boost was not

49

# specified, --with-boost=$BOOST_ROOT is implicitly used.

50

# For more README and documentation, go to http://github.com/tsuna/boost.m4

51

# Note: THESE MACROS ASSUME THAT YOU USE LIBTOOL. If you don't, don't worry,

52

# simply read the README, it will show you what to do step by step.

dnl Optimization hacks: compiling C++ is slow, especially with Boost. What

347

dnl we're trying to do here is guess the right combination of link flags

348

dnl (LIBS / LDFLAGS) to use a given library. This can take several

349

dnl iterations before it succeeds and is thus *very* slow. So what we do

350

dnl instead is that we compile the code first (and thus get an object file,

351

dnl typically conftest.o). Then we try various combinations of link flags

352

dnl until we succeed to link conftest.o in an executable. The problem is

353

dnl that the various TRY_LINK / COMPILE_IFELSE macros of Autoconf always

354

dnl remove all the temporary files including conftest.o. So the trick here

355

dnl is to temporarily change the value of ac_objext so that conftest.o is

356

dnl preserved accross tests. This is obviously fragile and I will burn in

357

dnl hell for not respecting Autoconf's documented interfaces, but in the

358

dnl mean time, it optimizes the macro by a factor of 5 to 30.

359

dnl Another small optimization: the first argument of AC_COMPILE_IFELSE left
