Problem solved: In case anyone ever needs to know, here are the steps taken to solve the problem: {NOTE: A colleague helped me with this}. Re-loaded Boost, upgrading to v. 1.37 {this upgrade may be a red herring, but it didn't hurt). This version is very friendly to compiling in MS VS 2008 (version 9). Then, added the following, at the top of any relevant file: #include #define BOOST_TEST_MAIN "Test put_your_town_string_here" #include #include I am not sure if the first of these includes is required, but this always seems to work. Hopefully, someone will be helped by this e-mail at some point or other. Thanks, Sincerely, Joseph A. Marks e-mail: josephamarks@yahoo.com --- On Mon, 12/8/08, Joseph A. Marks wrote:
