Hi,

I don't know how to do it with the approach you suggest. What I do is build
all Boost libraries and install them in a given path, that will be platform
dependent. Later I add the following to the Jamroot of my project:

path-constant TOP : . ;
use-project /lib : $(TOP) ;

constant PLATFORM : [ os.environ PLATFORM ] ;

if $(PLATFORM) = mingw
{
    constant boost_inc_path : "c:\\msys\\1.0\\local\\include\\boost-1.45" ;
    constant boost_debug_lib_path :
"c:\\msys\\1.0\\local\\lib\\boost-1.45d_gcc-4.5.0" ;
    constant boost_release_lib_path :
"c:\\msys\\1.0\\local\\lib\\boost-1.45r_gcc-4.5.0" ;
    constant boost_debug_suffix : "-mgw45-mt-d-1_45" ;
    constant boost_release_suffix : "-mgw45-mt-1_45" ;
    constant boost_needed_libs : z ole32 oleaut32 ws2_32 ;
}
else if $(PLATFORM) = linux
{
    constant boost_inc_path : "/usr/include/boost-1.45" ;
    constant boost_debug_lib_path : "/usr/lib/boost-1.45d_gcc-4.5.2" ;
    constant boost_release_lib_path : "/usr/lib/boost-1.45r_gcc-4.5.2" ;
    constant boost_debug_suffix : "" ;
    constant boost_release_suffix : "" ;
    constant boost_needed_libs : z ;
}
else if $(PLATFORM) = mac
{
    constant boost_inc_path : "/opt/local/include" ;
    constant boost_debug_lib_path : "/opt/local/lib" ;
    constant boost_release_lib_path : "/opt/local/lib" ;
    constant boost_debug_suffix : "-mt" ;
    constant boost_release_suffix : "-mt" ;
    constant boost_needed_libs : z ;
}

lib $(boost_needed_libs) : : <link>shared ;
alias boost_debug_common : $(boost_needed_libs) : <variant>debug : :
<linkflags>"-L\"$(boost_debug_lib_path)\"" <include>$(boost_inc_path) ;
alias boost_release_common : $(boost_needed_libs) : <variant>release : :
<linkflags>"-L\"$(boost_release_lib_path)\"" <include>$(boost_inc_path) ;

# define external library (how to find lib and where to look for include
files)
lib _boost_iostreams_debug : : <name>boost_iostreams$(boost_debug_suffix)
<search>$(boost_debug_lib_path) <variant>debug : ;
lib _boost_iostreams_release : :
<name>boost_iostreams$(boost_release_suffix)
<search>$(boost_release_lib_path) <variant>release : ;
alias boost_iostreams : _boost_iostreams_debug boost_debug_common :
<link>shared <variant>debug : :  ;
alias boost_iostreams : _boost_iostreams_release boost_release_common :
<link>shared <variant>release : : ;
alias boost_iostreams : _boost_iostreams_debug boost_debug_common :
<link>static <variant>debug : :  ;
alias boost_iostreams : _boost_iostreams_release boost_release_common :
<link>static <variant>release : : ;

The last part about IOSTREAMS should be repeated for every non-just-headers
Boost library you need to use. Later, in the Jamfile of the library or
executable, I would use it as follows:

exe myapp : somesource.cpp /lib//boost_iostreams ;

Regards.
Jose.
