# 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 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 |

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