How to build 64-bit boost for visual studio on windows using the address-model flag?

I am trying to build boost on the x64 terminal for Visual Studio using these instructions: https://www.boost.org/doc/libs/1_62_0/more/getting_started/windows.html#get-boost

I do:

boostrap

then

.\b2 address-model=64

but it always says:

C:\boost_1_70_0>.\b2 address-model=64
Performing configuration checks

    - default address-model    : 32-bit
    - default architecture     : x86

Building the Boost C++ Libraries.

...

and then goes on to build 32 bit versions of everything. I know this because when I try and use boost for things like CMake it complains that its 32 bit:

C:\src\SimpleAmqpClient\simpleamqpclient-build>cmake -DBOOST_ROOT=C:\boost_1_70_0 -DBOOST_LIBRARYDIR=C:\boost_1_70_0\stage\lib ..

  but it set boost_chrono_FOUND to FALSE so package "boost_chrono" is
  considered to be NOT FOUND.  Reason given by package:

So yeah, how can I build 64-bit?

b2 cmake visual-studio boost c++

See the answer I gave here: How to build Boost 1.64 in 64 bits?
If you want to specify the toolset explicitly then Visual Studio 2019 is toolset=msvc-14.2

Note: ensure that you build it from a Visual Studio tools Command Prompt
and ignore the - default address-model : 32-bit output on the console, it builds 64 bit binaries.

I just ran into this problem. Even though I specified address-model=64 on the command line and the 32-bit tools weren't in my PATH and the 64-bit tools were, Jam used the 32-bit tools. And it didn't even know it was doing it: it put x64 in the names of the 32-bit libraries it created using the 32-bit tools that it had gone out of its way to find and invoke. I love "smart" build systems.

I don't know why it happened, but I worked around it by editing bin.v2\standalone\msvc\msvc-{version}\address-model-64\architecture-x86\msvc-setup.bat and moving ...\bin\Hostx64\x64 before ...\bin\HostX86\x86 in the SET PATH=... line.

As mentioned in another answer, it still reports "default address-model: 32-bit" even when it's correctly building 64-bit binaries.

My guide has detailed instructions that may be useful for how to build 64-bit boost on Windows 10 in Visual Studio 2019 with python and mpi support. I wrote the notes in case I ever needed to do it again.

I thought it might have something to do with leaving out --

b2 --address-model=64

But someone has told me that is not correct.
