Boost Users :

I built both x86 and x64 flavours of Boost 1.62 with Visual Studio 2017 RC using this approach:

1.       Boostrap from a shell configured using the x86 vcvars or x64 vcvars.

2.       Update the project-config.jam to include:
using msvc : 15.0 : <path to x86 or x64 cl.exe>

I had to make a small change to the auto_link.hpp:

# elif defined (BOOST_MSVC) && (BOOST_MSVC < 1910)

                // vc14:

#  define BOOST_LIB_TOOLSET “vc140”

# elif defined (BOOST_MSVC)

                // vc15:

#  define BOOST_LIB_TOOLSET “vc150”

Issues for me:

·         I failed to update the MSVC toolset detection in tools/build/src/tools/msvc.jam (hence fixing the version in project-config.jam)

·         For the x64 build, passing address-model=64 on the b2 command line didn’t work so I had to delete bin.v2 and stage folders between the x86 and x64 builds.
