I have boost-build.jam at I:\modular-boost
Suggestions please.
The boost-build.jam file from the sandbox
(http://svn.boost.org/svn/boost/sandbox/guild/boost-build.jam) needs
to be updated for the new
layout
of boost build. This is out of date:
local boost-build-src = [ if-has-file bootstrap.jam :
    [ MATCH --boost-build=(.*) : $(ARGV) ]
    $(BOOST_BUILD_PATH)
    $(BOOST_BUILD)
    $(boost-src)/tools/build/v2
    ] ;
'/v2' is no longer required in the path, and 'bootstrap.jam' is in a different directory now.
Changing it to
this might work:
local boost-build-src = [ if-has-file bootstrap.bat :
    [ MATCH --boost-build=(.*) : $(ARGV) ]
    $(BOOST_BUILD_PATH)
    $(BOOST_BUILD)
    $(boost-src)/tools/build
    ] ;
That changes the result but doesn't entirely solve the problem.
adding --boost=i:\modular-boost finds the licence text OK, but then
gives
Unable to load Boost.Build: could not find build system.
---------------------------------------------------------
I:\boost-sandbox\guild\boost-build.jam attempted to load the build system by invoking
   'boost-build I:\modular-boost\tools\build ;'
but we were unable to find "bootstrap.jam" in the specified directory
or in BOOST_BUILD_PATH (searching I:\modular-boost\tools\build).
which is because it does not contain this file "bootstrap.jam" (and
nor does i:\modular-boost)
Oh, I guess it needs to find the 'tools/build/src' path where bootstrap.jam is located. Maybe this
would
work:
local boost-build-src = [ if-has-file bootstrap.jam :
    [ MATCH --boost-build=(.*) : $(ARGV) ]
    $(BOOST_BUILD_PATH)
    $(BOOST_BUILD)
    $(boost-src)/tools/build/src
    ] ;
Yes - works for me :-)

But to avoid providing BOOST or BOOST_ROOT environment variables, or parameter
--boost=i:\modular-boost

I also added

#~ Attempts to find the Boost source tree...
#~ --boost=i:\modular-boost may be needed.
local boost-src = [ if-has-file LICENSE_1_0.txt :
    [ MATCH --boost=(.*) : $(ARGV) ]
    $(BOOST)
    $(.boost-build-file:D)/../../modular-boost/ <<<<<<<<<<<<<<<<  new for modular-boost
    $(.boost-build-file:D)/../boost
    $(.boost-build-file:D)/../Trunk
    ] ;

I fear that I am not the only one who will need to make quite a few adjustments  (and also to MSVC
solutions/projects) as a result of modularization.

Thanks again.

Paul
