David- When you asked me to run the following lines: bjam -f- "-sTOOLS=mingw" install ECHO $(TOOLS) ; ^Z I see the following: bjam -f- "-sTOOLS=mingw" install (hundreds of lines of error text go by here) ECHO $(TOOLS) ; reply is: sh: ./TOOLS: is a directory ...and nothing is displayed after entering ctrl-Z :) The reply to ECHO $(TOOLS) ; seems odd. I doubt that this is what you were expecting. There *is* a 'tools' directory under boost_1_31_0, but not a 'TOOLS' directory. Case-sensitivity issues? I have also run the following: bjam -d+5 "-sTOOLS=mingw" install > bug.out Note that not everything is captured in 'bug.out'. I see hundreds of lines of the following on the console: The system cannot find the path specified. This is not surprising as I don't have VC7 installed. Unfortunately I don't have a place to publicly park the compressed 'bug.out' file so I will email it directly to you. However, here's the first few lines if that's of any help.
