If you're using 2.0-m10, you need to add "path-constant" invocation to

path-constant BIN_ROOT : whatever ;

If you're using CVS version, you can add this either to project-root.jam orto
Jamfile. In fact, you better have one file called Jamroot at top-level, and
don't bother with difference between project-root.jam and top-level Jamfile.

project Project2
: requirements <dependency>..//Project2

might be enough?

You can check for directory existence with the glob rule.


if [ glob ../Project1 ]

The argument to 'glob' is a pattern relative to Jamfile location.
