Re: Problems using date-time library

I got that too. I tried to fix it by moving the .cpp files from
boost_1_29_0\libs\date_time\src\gregorian to
boost_1_29_0\boost\date_time\gregorian. And it seemed like I also
needed to rename the .ipp file in boost_1_29_0\boost\date_time to be
.cpp. Don't know for sure if it worked because I now get: fatal error
C1063. Too many templates I guess :(
