I am trying to install boost -- I have a bloodshed dev c++ compiler 4.9.9.2 and windows xp. I am trying to install boost and then quantlib but am stuck at the boost stage. I find that the instructions at boost.org appear to assume more knowledge of dos commands and path environment variables than I possess. I sometimes get the message that bjam is not recognized, and I sometimes get the message that the toolsets are not configured. I do know how to add paths to the path environment variable but not much else. I tried to follow Terrence August's online instructions (which are excellent) http://www.stanford.edu/~taugust/quantlib.html but this interfered with my dev cpp compiler. Thank you very much for your help. Paul Epstein ____________________________________________________________________________________Be a better Globetrotter.
