Update procedure for boost compilation (>=1.81) using oneAPI toolkit (2024.2.1.20240711) on Windows

Hello

I need to compile Boost 1.81 binaries for our development purposes, preferably using the Clang compiler. I found a page describing a procedure that should be valid for the C++ Compiler 2022.0.0 and Boost versions 1.75/1.78 (Building Boost with Intel® oneAPI). However, these instructions do not seem to work with Boost 1.81, and I fear they might not work with any newer versions either.

First of all, even after editing the project-config.jam file, whenever I run the bootstrap script, the toolset chosen ends up being VC143, regardless of whether I added the clang-win line in the file. If I try to run the bootstrap script with an invalid toolset option, the available options are:

• borland
• como
• gcc
• gcc-nocygwin
• intel-win32
• mingw
• vc12
• vc14
• vc141
• vc142
• vc143

In my case, I'd like to compile the x64 binaries, so the intel-win32 option would not be applicable. By inspecting the bootstrap script, I can see that the following options exist:

REM Ideally, we should obtain the toolset that build.bat has

REM guessed. However, it uses setlocal at the start and does not

REM export BOOST_JAM_TOOLSET, and I don't know how to do that

REM properly. Default to msvc if not specified.

SET TOOLSET=msvc

IF "%1"=="gcc" SET TOOLSET=gcc

IF "%1"=="clang" SET TOOLSET=clang

IF "%1"=="borland" SET TOOLSET=embarcadero

IF "%1"=="vc71" SET TOOLSET=msvc : 7.1

IF "%1"=="vc8" SET TOOLSET=msvc : 8.0

IF "%1"=="vc9" SET TOOLSET=msvc : 9.0

IF "%1"=="vc10" SET TOOLSET=msvc : 10.0

IF "%1"=="vc11" SET TOOLSET=msvc : 11.0

IF "%1"=="vc12" SET TOOLSET=msvc : 12.0

IF "%1"=="vc14" SET TOOLSET=msvc : 14.0

IF "%1"=="vc141" SET TOOLSET=msvc : 14.1

IF "%1"=="vc142" SET TOOLSET=msvc : 14.2

IF "%1"=="vc143" SET TOOLSET=msvc : 14.3

Even though there seems to be a clang option, I end up getting many errors during the bootstrap execution, as it seems that MSVC files are being targeted instead.

Is there an updated procedure somewhere else?

It seems that the clang-win option mentioned in the tutorial I posted in the original post is naturally supported by boost only for versions >=1.85. That means that I remain blocked for my case with version 1.81.
