I'm continuing to have trouble compiling 64-bit versions of the Boost libraries on Windows using VS2008. I've used a number of the tips posted online including: bjam --toolset=msvc-9.0 address-space=64 but watching the Task Manager I see that it always launches the 32-bit version of the compiler. Does someone have the correct BJAM command line to make this work? I'm using Boost 1.34.1 which I patched in a couple of places to have it recognize the 9.0 (internally version 15) VS 2008 toolset. Any help much appreciated. Thanks. Chris. _______________________________________________________ The contents of this e-mail are intended for the named addressee only.
