All you need is a "boost-build.jam" file anywhere "above" the project
files with, at minimum this in it:
boost-build <path-to-boost-build-source-root> ;
How you set the path can be as simple as hard wiring.. Or as complex as
doing some smart file searching to find it. For example I use a search
that looks for some common env vars, common relative boost source trees,
some local minimal boost source trees. For example:
# Copyright Redshift Software, Inc. 2008.
# Distributed under the Boost Software License, Version 1.0.
# (See accompanying file LICENSE_1_0.txt or copy at
# For instructions see Jamfile.v2, or "bjam --help".
local rule if-has-file ( file + : dir * )
local result ;
result = [ GLOB $(dir) : $(file) ] ;
return $(result:P) ;
#~ Attempts to find the Boost source tree...
local boost-src = [ if-has-file configure :
[ MATCH --boost=(.*) : $(ARGV) ]
#~ Attempts to find the Boost.Build files...
local boost-build-src = [ if-has-file bootstrap.jam :
[ MATCH --boost-build=(.*) : $(ARGV) ]
#~ Set some common vars to refer to the Boost sources...
BOOST ?= $(boost-src) ;
BOOST_ROOT ?= $(boost-src) ;
#~ Our preferred jamfiles...
JAMFILE = build.jam ;
JAMROOT = root.jam ;
#~ Add the build extensions to the search path...
#~ And load up Boost.Build...
boost-build $(boost-build-src) ;
