+
+This is an extra tool, not bundled with the default waf binary.
+To add the boost tool to the waf file:
+$ ./waf-light --tools=compat15,boost
+ or, if you have waf >= 1.6.2
+$ ./waf update --files=boost
+
+When using this tool, the wscript will look like:
+
+ def options(opt):
+ opt.load('compiler_cxx boost')
+
+ def configure(conf):
+ conf.load('compiler_cxx boost')
+ conf.check_boost(lib='system filesystem')
+
+ def build(bld):
+ bld(source='main.cpp', target='app', use='BOOST')
+
+Options are generated, in order to specify the location of boost includes/libraries.
+The `check_boost` configuration function allows to specify the used boost libraries.
+It can also provide default arguments to the --boost-mt command-line arguments.
+Everything will be packaged together in a BOOST component that you can use.
+
+When using MSVC, a lot of compilation flags need to match your BOOST build configuration:
+ - you may have to add /EHsc to your CXXFLAGS or define boost::throw_exception if BOOST_NO_EXCEPTIONS is defined.
+ Errors: C4530
+ - boost libraries will try to be smart and use the (pretty but often not useful) auto-linking feature of MSVC
+ So before calling `conf.check_boost` you might want to disabling by adding
+ conf.env.DEFINES_BOOST += ['BOOST_ALL_NO_LIB']
+ Errors:
+ - boost might also be compiled with /MT, which links the runtime statically.
+ If you have problems with redefined symbols,
+ self.env['DEFINES_%s' % var] += ['BOOST_ALL_NO_LIB']
+ self.env['CXXFLAGS_%s' % var] += ['/MD', '/EHsc']
+Passing `--boost-linkage_autodetect` might help ensuring having a correct linkage in some basic cases.
