You can specify these # paths in site-config.jam, user-config.jam or in the environment. # A new feature is provided to request a specific API: # win32 and # # The naming of the resulting libraries is mostly the same for the # variant native to the build platform, i.e. # boost_thread and the boost specific tagging. # For the library variant that is not native on the build platform # an additional tag is applied: # boost_thread_pthread for the pthread variant on windows, and # boost_thread_win32 for the win32 variant (likely when built on cygwin). # # To request the pthread variant on windows, from boost root you would # say e.g: # bjam msvc-8.0 --with-thread install threadapi=pthread ######################################################################### import os ; import feature ; import indirect ; import path ; project boost/thread : source-location ../src : requirements multi static:BOOST_THREAD_BUILD_LIB=1 shared:BOOST_THREAD_BUILD_DLL=1 -@$(BOOST_JAMROOT_MODULE)%$(BOOST_JAMROOT_MODULE).tag @$(__name__).tag : default-build multi ; local rule default_threadapi ( ) { local api = pthread ; if [ os.name ] = "NT" { api = win32 ; } return $(api) ; } feature.feature threadapi : pthread win32 : propagated ; feature.set-default threadapi : [ default_threadapi ] ; rule tag ( name : type ? : property-set ) { local result = $(name) ; if $(type) in STATIC_LIB SHARED_LIB IMPORT_LIB { local api = [ $(property-set).get ] ; # non native api gets additional tag if $(api) != [ default_threadapi ] { result = $(result)_$(api) ; } } # forward to the boost tagging rule return [ indirect.call $(BOOST_JAMROOT_MODULE)%$(BOOST_JAMROOT_MODULE).tag $(result) : $(type) : $(property-set) ] ; } rule win32_pthread_paths ( properties * ) { local result ; local PTW32_INCLUDE ; local PTW32_LIB ; PTW32_INCLUDE = [ modules.peek : PTW32_INCLUDE ] ; PTW32_LIB = [ modules.peek : PTW32_LIB ] ; PTW32_INCLUDE ?= [ modules.peek user-config : PTW32_INCLUDE ] ; PTW32_LIB ?= [ modules.peek user-config : PTW32_LIB ] ; PTW32_INCLUDE ?= [ modules.peek site-config : PTW32_INCLUDE ] ; PTW32_LIB ?= [ modules.peek site-config : PTW32_LIB ] ; if !
