[Boost-build] Using Environment Variables in Boost.Build JamRoot file

I'm having an issue where I can't use the Windows Environment variables
in the JamRoot file.  I'm having to do this:

 

# Specify the path to the Boost project.  If you move this project,

# adjust the path to refer to the Boost root directory.

use-project boost 

  : C:/3rdparty/boost_1_34_0 ;

 

When, in reality, my preference would be this:

 

# Specify the path to the Boost project.  If you move this project,

# adjust the path to refer to the Boost root directory.

use-project boost 

  : $(BOOST_ROOT);

 

However, when I take the second approach, I get the following errors:

 

bjam toolset=msvc --verbose-test test

Jamroot:8: in modules.load

*** argument error

* rule use-project ( id : where )

* called with: ( boost :  )

* missing argument where

boost-build

 

E:\quicktest\boost-build.jam:7: in module scope

 

My boost-build.jam seems to take the environment variable with no issue.
I do this:

 

# Copyright David Abrahams 2006. Distributed under the Boost

# Software License, Version 1.0. (See accompanying

# file LICENSE_1_0.txt or copy at http://www.boost.org/LICENSE_1_0.txt)

 

# Edit this path to point at the tools/build/v2 subdirectory of your

# Boost installation.  Absolute paths work, too.

boost-build $BOOST_ROOT/tools/build/v2 ;

 

 

Any ideas?

 

Thanks in advance,
