You should be able to build msvc ARM64 with

architecture=arm address-model=64

so long as you’re using B2 4.0+.

Thanks

Subject: [EXTERNAL] [Boost-build] compiling for msvc arm64

Hi all,

  I was intending to compile boost for msvc arm64.

  When I execute the following command,

b2 toolset=msvc architecture=arm64 address-model=64

  I get an error saying that arm64 is not an valid architecture. Can someone pls point me to the correct way to build arm64 with msvc v141?

Thanks.
