I have just done a checkout boost from cvs.sourceforge.net and tried to build with VC8 (cl version 14.0.40607.16) and Microsoft Platform SDK for Windows XP SP2, using the following commands: tools\build\jam_src\build.bat tools\build\jam_src\bin.ntx86\bjam "-sTOOLS=vc-8_0" This resulted in lots of these warnings: option 'Og' has been deprecated option 'Gs' has been deprecated ignoring unknown option '/MLd' ignoring unknown option '/ML' I read that Jam V2 should fix those, but I cannot see how to build it. More serious was the following compilation error: lexical_cast.hpp(150): error C2679: binary '>>' : no operator found which takes a right-hand operand of type 'std::basic_string<_Elem,_Traits,_Ax>' That file hasn't changed since last September, so am I wasting my time trying to use VC8? Thanks, Keith MacDonald
