Use a newer boost.m4 to fix detection of boost_major_version. Now we need to specify the boost LIBS to link against.

# 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 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.
|

dnl Another small optimization: the first argument of AC_COMPILE_IFELSE left

dnl empty because the test file is generated only once above (before we
