Unable to load Boost.Build: could not find "boost-build.jam"
---------------------------------------------------------------
BOOST_ROOT must be set, either in the environment, or
on the command-line with -sBOOST_ROOT=..., to the root
of the boost installation.

Attempted search from E:\jenkins\temp\boost\objyboost up to the root
at E:/jenkins/temp/boost/share/boost-build

Please consult the documentation at 'http://www.boost.org'.

Would the following work:

Here's the original command:

cmd /c E:\boost\src\b2 --without-test --prefix=E:\boost --build-dir=build
link=shared threading=multi runtime-link=shared toolset=msvc-12.0
architecture=x86 address-model=64 variant=debug,release, stage

Trying with BOOST_BUILD_PATH:

cmd /c E:\boost\src\b2 -sBOOST_BUILD_PATH=E:\boost\src --without-test
--prefix=E:\boost --build-dir=build link=shared threading=multi
runtime-link=shared toolset=msvc-12.0 architecture=x86 address-model=64
variant=debug,release, stage

Which I believe gets me to the inspect error that John mentioned below:

>cmd /c E:\boost\src\b2 -sBOOST_BUILD_PATH=E:\boost\src --without-test
--prefix=E:\boost --build-dir=build link=shared threading=multi
runtime-link=shared toolset=msvc-12.0 architecture=x86 address-model=64

Great!  Thank you!  But...I'm wondering if trying 1.56 might be better for
me.  My only goal was to build boost with msvc12.0.  I know that 1.55 has
an issue with building serialization in msvc12.0, which is why I moved to
1.57.  Am I stuck applying a patch, regardless of which release I move to?

Regards,
Kevin
