[question] MSVC Clang-Cl compiler error on Boost recipe, why?

[ibis-hdl]

What is your question?

I am trying to build a Conan v2 recipe on Windows 10 with VS 2022 (community) and the supplied clang-cl - with boost 1.86 recipe. I have created a Conan profile msvc-cl for this purpose

[settings]
arch=x86_64
build_type=Release
compiler=clang
compiler.cppstd=gnu17
compiler.runtime=dynamic
compiler.runtime_version=v143
compiler.version=18
os=Windows
[conf]
tools.cmake.cmaketoolchain:generator=Visual Studio 17 2022

set the compiler.version=18 to the version number of the bundled clang-cl,

> clang-cl --version
clang version 18.1.8
Target: x86_64-pc-windows-msvc
Thread model: posix
InstalledDir: C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\Llvm\x64\bin

and tested it (as suggested in Conan's doc) successfully with conan new cmake_lib.

Conan's command line is:

> pwsh -Command conan install . --settings compiler.cppstd=20 --settings build_type=Debug --conf tools.cmake.cmaketoolchain:generator="Ninja Multi-Config" --build=missing --profile:all=msvc-cl

and the error messages now appears in the real project for all recipes:

...

Even if I set compiler.runtime_version=v144 I wasn't able to successfully compile the recipes (Somewhere in the logs I saw v14.4, can't remember where, vswhere doesn't seems to show it).

Have I forgotten something, or is the Boost recipe not intended for this?

The conanfile.py is nothing special:

from conan import ConanFile
from conan.tools.cmake import CMakeToolchain, CMakeDeps, cmake_layout
from conan.tools.files import load, save
import json
import os

class IbisConan(ConanFile):
    settings = "os", "compiler", "build_type", "arch"

        self.requires('fmt/11.0.2')
        self.requires('range-v3/0.12.0')
        self.requires('strong_type/v15')

    def layout(self):
        cmake_layout(self)

    def generate(self):
        deps = CMakeDeps(self)
        deps.generate()
        tc = CMakeToolchain(self)
        tc.user_presets_path = "ConanCMakePresets.json"
        tc.generate()
