Extension of usage of Tsuna's boost.m4 macro.

  • boost.m4 from https://github.com/tsuna/boost.m4.git (serial 16 + updates).
  • LinearAlgebra does not depend on any boost libs only two headers and CodePatterns.
  • Presence and Usability of every boost header and lib is now checked.
  • Using updated ax_codepatterns.m4.
  • FIX: boost has not been possible to link with if not residing under some default path. This is now possible.
  • Property mode set to 100644

37# This file provides several macros to use the various Boost libraries.
38# The first macro is BOOST_REQUIRE. It will simply check if it's possible to
39# find the Boost headers of a given (optional) minimum version and it will
40# define BOOST_CPPFLAGS accordingly. It will add an option --with-boost to
41# your configure so that users can specify non standard locations.
42# If the user's environment contains BOOST_ROOT and --with-boost was not
43# specified, --with-boost=$BOOST_ROOT is implicitly used.
44# For more README and documentation, go to http://github.com/tsuna/boost.m4
45# Note: THESE MACROS ASSUME THAT YOU USE LIBTOOL. If you don't, don't worry,
46# simply read the README, it will show you what to do step by step.

340dnl Optimization hacks: compiling C++ is slow, especially with Boost. What
341dnl we're trying to do here is guess the right combination of link flags
342dnl (LIBS / LDFLAGS) to use a given library. This can take several
343dnl iterations before it succeeds and is thus *very* slow. So what we do
344dnl instead is that we compile the code first (and thus get an object file,
345dnl typically conftest.o). Then we try various combinations of link flags
346dnl until we succeed to link conftest.o in an executable. The problem is
347dnl that the various TRY_LINK / COMPILE_IFELSE macros of Autoconf always
348dnl remove all the temporary files including conftest.o. So the trick here
349dnl is to temporarily change the value of ac_objext so that conftest.o is
350dnl preserved accross tests. This is obviously fragile and I will burn in
351dnl hell for not respecting Autoconf's documented interfaces, but in the
352dnl mean time, it optimizes the macro by a factor of 5 to 30.
