| 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. |

| 341 | dnl Optimization hacks: compiling C++ is slow, especially with Boost.  What | 
|---|
| 342 | dnl we're trying to do here is guess the right combination of link flags | 
|---|
| 343 | dnl (LIBS / LDFLAGS) to use a given library.  This can take several | 
|---|
| 344 | dnl iterations before it succeeds and is thus *very* slow.  So what we do | 
|---|
| 345 | dnl instead is that we compile the code first (and thus get an object file, | 
|---|
| 346 | dnl typically conftest.o).  Then we try various combinations of link flags | 
|---|
| 347 | dnl until we succeed to link conftest.o in an executable.  The problem is | 
|---|
| 348 | dnl that the various TRY_LINK / COMPILE_IFELSE macros of Autoconf always | 
|---|
| 349 | dnl remove all the temporary files including conftest.o.  So the trick here | 
|---|
| 350 | dnl is to temporarily change the value of ac_objext so that conftest.o is | 
|---|
| 351 | dnl preserved accross tests.  This is obviously fragile and I will burn in | 
|---|
| 352 | dnl hell for not respecting Autoconf's documented interfaces, but in the | 
|---|
| 353 | dnl mean time, it optimizes the macro by a factor of 5 to 30. |
