[C++-sig] Build Errors Making the "quickstart" Demo Project

Hi, thanks for your reply.
Yes, you are correct that "our attempts to build and/or use stock BPL is
failing when building the quickstart demo". The boost build completes
normally (but doesn't show any messages about running any tests) and
specifies strings to add to the LIB and INCLUDE paths. At that point we
simply CD to the quickstart sample directory and run "B2". This second
build fails with a compiler error about an ambiguous call to an
overloaded function.
Is there something else that needs to be set? My understanding was that
the earlier instructions for setting up the environment (bootstrap,
user-config.jam) set up the environment for building both boost (which
worked) and quickstart (which didn't).
Here is the complete sequence:
............................................
C:\Boost\boost_1_47_0>.\b2
Building the Boost C++ Libraries.
Performing configuration checks
- has_icu builds : no
warning: Graph library does not contain MPI-based parallel components.
note: to enable them, add "using mpi ;" to your user-config.jam
- ../config//has_gcc_visibility builds : no
- ../config//has_long_double_support builds : yes
warning: skipping optional Message Passing Interface (MPI) library.
note: to enable MPI support, add "using mpi ;" to user-config.jam.
note: to suppress this message, pass "--without-mpi" to bjam.
note: otherwise, you can safely ignore this message.
Component configuration:
- chrono : building
- date_time : building
- exception : building
- filesystem : building
- graph : building
- graph_parallel : building
- iostreams : building
- math : building
- mpi : building
- program_options : building
- python : building
- random : building
- regex : building
- serialization : building
- signals : building
- system : building
- test : building
- thread : building

Am I missing something?
_____________________________________________________
If I am understanding you correctly, your attempts to build and/or use
stock BPL is failing when building the quickstart demo?
If so, there is surely some issue with your build environment as Boost
runs a series of automated regression tests which catch build failures.
If I'm not right in understanding you correctly, please do explain
further.
