What steps will reproduce the bug?

On a brand new Mac, following the BUILDING.md steps, specifically

To build Node.js:
export CXX=g++-12
•/configure
make -j4

How often does it reproduce? Is there a required condition?

Always

What is the expected behavior? Why is that the expected behavior?

It should compile successfully by following the BUILDING.md steps.

If I skip the export CXX=g++-12 command, it compiles successfully.

Maybe it is a documentation error, or a dependency step that is not working as expected in the latest Mac versions

What do you see instead?

An error:

cc1plus: error: '-Werror=undefined-inline': no option '-Wundefined-inline'; did you mean '-Wundefined-do-loop'?

export CXX=g++-12 was added recently (4c27393), but it's wrong for mac. You can omit this step.

[vagostep]

@targos yes! By skipping it, it works.

should we update the doc or should we wait for it to work again?

[targos]

The documentation should be updated. Would you like to try and open a PR?

[vagostep]

@targos sure! on it.
