How to build 64-bit boost for visual studio on win

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 ..

  Found package configuration file:

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

  No suitable build variant has been found.

So yeah, how can I build 64-bit?

回答1:

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.

回答2:

See my guide for detailed instructions for how to build 64-bit boost on Windows 10 in Visual Studio 2019 with python and mpi support.

Also the syntax might matter. Maybe because you didn't use -- it gets ignored.
