Question

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?

Answer 1

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.
