[Build] Build script for MacOS fails for targets older than 13.4 because tests can not be built

[juhanisimola-yousician]

Describe the issue

According to https://onnxruntime.ai/docs/build/inferencing.html, "By default, ONNX Runtime is configured to be built for a minimum target macOS version of 10.12." In practice, when the runtime is built without specifying a target OS it is built for the major OS version the build machine is running (15.0 when building on 15.4 in my case). When the --apple_deploy_target argument is set to anything less than 13.4, the build fails because the tests are using functionality that is not available on older MacOS versions. The runtime itself is compiled, but I couldn't find an option to disable building the tests.

GCC / Compiler Version

Xcode 15.4 and 16.3, SDK 16.3

[juhanisimola-yousician]

Oh well. x86_64 build fails with Xcode 16.3 because of this too:

Please use an older version of ONNX Runtime, or increase the target OS version.

Our packaging pipeline set MACOSX_DEPLOYMENT_TARGET to be 13.3 and it works well:
https://github.com/microsoft/onnxruntime/blob/main/tools/ci_build/github/azure-pipelines/templates/mac-cpu-packing-jobs.yml#L34

But you were saying 13.4 . Probably it is an SDK issue? Our pipelines use XCode 15.3.0. Yours are newer.

[snnn]

It is related to PR #17361 , which increased the min MacOS version to 13.3.

[juhanisimola-yousician]

I doubt that Apple has retroactively removed std::to_chars from macOS 13.3 when they released SDK 16. In the past I've seen that code that used std::filesystem::path compiled when targeting older macOS versions (10.14 IIRC) but didn't work, and later SDKs declared it unavailable on those versions. Are you running the tests on macOS 13.3?

[lumpidu]

I can confirm increasing "--apple_deploy_target=13.4" from 13.3 fixes the issue. However I encounter the same error as @juhanisimola-yousician for compilation of mlas.

(And btw. cmake 4.0 as now the default on Homebrew also doesn't work opposed to the Releases notes.)

[snnn]

The mlas issue is the same as #23180

[juhanisimola-yousician]

Documentation still says "By default, ONNX Runtime is configured to be built for a minimum target macOS version of 10.12", but who cares?

[lumpidu]

Could someone from Microsoft confirm the build issue? Don't you use newer XCode versions when building OnnxRuntime?
