Build (bbv2) simple project using boost lib

Hello all, I've been trying to work with Boost.Build V2 (M10) for a
couple of days now, but I don't seem to get it working for a simple
project using the Boost filesystem library, so now it seems time to get
help.

I'm working on Windows XP, amd 64, Visual C++.NET 2003.
I installed the full Boost 1.33.0 in "Y:\libraries\boost_1_33_0". Then,
afterdownloading the latest bjam I did a build using Boost.Build V1 with
the following command:

Y:libraries\boost_1_33_0> bjam "-sTOOLS=vc-7_1"
--prefix=Y:\libraries\boost --builddir=../boost_tmp_build
--with-python-root=Y:\tools\python24 install

That seems to have worked without problems, so I have an installation in
Y:\libraries\boost now. (Question in between: how could I have done this
using Boost.Build V2? I don't know how to do the option settings then.)

Now, I have a project in the directory
Y:\home\work\programming\wvm2su\
consisting of a single cpp file: wvm2su.cpp, which is supposed to be
compiled into an application, so I made a Jamfile with the single line:

------------------
exe wvm2su : wvm2su.cpp /boost/filesystem ;
------------------

One directory above (Y:\home\work\programming\) I made the following
Jamroot file:

--------------------------
use-project /boost : Y:/libraries/boost_1_33_0 ;

project
: requirements
<include>.
;
----------------------------

this should serve to make the boost modules known to bjam and to
indicate that I have some include files in different subdirectories
(mentioned explicitly in the #include statements).

I think this should be sufficient for a build. However, I get the
following output from bjam, which leads to some questions that I state
below:

--------------------------------------------------

QUESTIONS:

- Why doesn't bjam use my pre-built libraries? I can understand that he
does not really know about them, but how do I then make the location known?

- Ok, so now he builds the libraries 'on demand' in a special puprose
path, but why doesn't he build the right ones then? Why doesn't he find
the libraries he's just made?

- I kind of like the fact that the libraries are built 'on demand', but
how do I then configure a proper path? Also, during a 'bjam clean' these
libs are removed as well. How do I prevent that?

- What are these warnings on Python and so on for? During the build of
the Boost libraries I set the Python path, but here and now it is
irrelevant.

- I get the impression that I'm misunderstanding things, so what is the
proper way of using boost libraries and Boost.Build. I was surprised to
see that none of the examples in the Boost.Build V2 directory actually
uses a boost library. So I don't seem to have a good example.

I think that will do for the moment, and I appreciate your help.

Thanks,

Harrie
