 | |
| # 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.
 | |
| # For more README and documentation, go to http://repo.or.cz/w/boost.m4.git

| # 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 Optimization hacks: compiling C++ is slow, especially with Boost.  What
 | |
| dnl we're trying to do here is guess the right combination of link flags
 | |
| dnl (LIBS / LDFLAGS) to use a given library.  This can take several
 | |
| dnl iterations before it succeeds and is thus *very* slow.  So what we do
 | |
| dnl instead is that we compile the code first (and thus get an object file,
 | |
| 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
