[Boost-users] Moving my Boost installation

I have Boost installed under Fedora13 in /usr/include, not installed by me, but I imagine done as part of installing Fedora. I have a codebase that uses Boost and builds perfectly, using gcc 4.5.1 Now, if I move my Boost installation mv /usr/include/boost ~rgj/xx and add an appropriate include directive to my compile lines, I get compile errors from Boost headers /home/rgj/xx/boost/date_time/gregorian/conversion.hpp: In function ‘tm boost::gregorian::to_tm(const boost::gregorian::date&)’: /home/rgj/xx/boost/date_time/gregorian/conversion.hpp|44 col 23| error: missing initializer for member ‘tm::tm_sec’ etc, etc Obviously I'm having a minor aberration here...what am I doing wrong? Thx, - Rob.
