I have a C++ project which is using boost. The whole project is built using scons + Visual Studio 2008. We've installed Visual Studio 2010 and it turned out scons was attempting to use the later compiler instead of the old one - and failed to build the project as boost and visual studio 2010 don't like each other very much - yet. We'd like to suppress this and force scons to use the 2008 version. Is this possible? How do we do this?
You can modify the scons Environment() by just choosing
the version you want:
env = Environment(MSVC_VERSION=<someversion>)
From the scons manpage:

MSVC_VERSION   Sets the preferred 
  version of Microsoft Visual C/C++ to
  use.
If $MSVC_VERSION is not set, SCons
  will (by default) select the latest
  version of Visual C/C++ installed on
  your system.  If the specified version
  isn't installed, tool initialization
  will fail.  This variable  must be 
  passed  as  an argument to the
  Environment() constructor; setting it
  later has no effect.  Set it to an
  unexpected value (e.g. "XXX") to see
  the valid values on your system.
Forcing scons to use older compiler?
