I found the problem. What I had done was to declare BOOST environment variables and these conflicted with the bjam processing of the files. Maybe a note should be added to the user instructions for building Boost in Windows along the line: "If you have any environment variables such as BOOST_INCLUDE, BOOST_LIB, BOOST_ROOT, BOOST_VERSION. Delete or rename them before running bjam."

I suspect (but may be wrong) that "/" instrad of "\" may be causing the problem. Andrew ___________________________________________ Andrew J. P.
