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 :  )

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,
