[Boost-users] cannot open file 'libboost_date_time-vc71-sgd-1_33_1.lib'

Hi, I am new to boost libraries. I have viewed some samples in http://www.boost.org/doc/html/date_time/examples.html#date_time.examples.day... in which i tried to build "Days Alive" example. The application reports: boost1 fatal error LNK1104: cannot open file 'libboost_date_time-vc71-sgd-1_33_1.lib' I have searched this in my list of libraries/files installed, but failed to find the same. Can any one please help how to overcome this error. Thanks, Arun.
