Hi! I need to build the boost libraries, and eventually my own application, in 64 bi t mode on Windows, but unfortunately I haven't been able to find any information on how to do so. Does anyone here have any tips? Typically, for a 32 build of boost.thread, for instance, I would type "bjam --with-thread -sTOOLS=vc-8_0 stage", but I don't know what the invocation should be for a 64 bit build. I'm using Visual C++ 2005 (the full version, not "express"). Thanks! Jarl.
