Note the command line, the boost include path isn't there, so you need to 
adjust your makefile.

I'm also a little surprised not to see a message that <boost/shared_ptr.hpp> 
couldn't be found.  Just tripple checking, but you did include that file in 
cash_flow.cpp didn't you :-)

You don't need to link to any external libs to use shared_ptr either.

HTH, John.
