So I was wondering if I even need this library? Aren't all boost classes compiled via hpp. I #defined BOOST_DATE_TIME_NO_LIB in my header file and the program compiles and works fine. So what is the purpose of this definition. I am using boost 1.32 along with Visual Studio 6.0. I have compiled it on Linux successfully, but I have not ran it yet.

No - not all Boost classes are compiled via hpp (aka "header-only").
Some boost libraries are compiled separately, and must be linked in.

Date-time is a hybrid. Some of the functionality is in header files, and if that's all that you use, then you can #define BOOST_DATE_TIME_NO_LIB, and continue on your merry way. However, if you use other parts of date-time, then you'll have to link against the prebuilt library.
