(answering the mail from Thomas Lemaire)

I've attached to this mail the .m4 macros that I made to configure boost
automatically in my autoconf/automake projects. It's not complete, nor
optimal, but suit my needs.

Put it in your /usr/share/aclocal directory and in your configure.ac
put:

RS_BOOST([1.32.0],[],[AC_MSG_ERROR([Package requires the Boost C++ 
                       libraries!])])
RS_BOOST_REGEX
RS_BOOST_THREAD
RS_BOOST_DATE_TIME
RS_BOOST_PROGRAM_OPTIONS

it'll create acsubst'ed BOOST_CPPFLAGS, BOOST_LIBS and BOOST_LIBS_R
Since I use it to compile for ming32 (win32) and gcc (linux) targets,
it's good to have AC_CANONICAL_TARGET right before AM_INIT_AUTOMAKE if
you want the m4 to choose between mgw and gcc libraries according to the
target you're building for. And if you define something like
AC_ARG_ENABLE(debug,....), thus defining enable_debug variable, the m4
will select the debug/release libraries whether enable_debug is yes or no.

Then you should put AM_CPPFLAGS=@BOOST_CPPFLAGS@, LIBS=@BOOST_LIBS@ (or
@BOOST_LIBS_R@ if you want the recurrent (thread-safe) version of the
libraries) somewhere in a Makefile.am

That's it... I hope it'll be as useful to you as it is being to me.
