Hi I am trying to build the boost libraries on XP with the VC-8 compiler from the Express edition. I have downloaded boost-1-33-1 and bjam boost-jam-3.1.13-1-ntx86. I tried to follow the instructions at http://www.boost.org/tools/build/v1/vc-8_0-tools.html. It's not clear to me if the msvc tools and the vc8 extension have to be installed or are part of bjam. I can't find a download for the tools though. Ignoring that, I simply ran up the hopefully correct environment by running "C:\Program Files\Microsoft Platform SDK for Windows Server 2003 R2\Setup\SetEnvLaunchWinXP32Retail.Cmd" /XP32 /RETAIL and then vcvars32.bat. I also set VC80_ROOT to my VC8 directory. Whatever I try I get the same result as below. It's trying to invoke VC7 which I don't have. Any help appreciated.
