C23 syntax highlighting in STM32CubeIDE (e.g. constexpr)

[A.D.]

The STM32 toolchain based on gcc 13.3 already supports a lot of C23 features, e.g. constexpr. This is really awesome.

But the current version of CubeIDE seems not to be able yet to parse these new features, so syntax checking / highlighting / code linking breaks.

Is there any simple workaround for this? Or is there information available, whether the next version of CubeIDE will update this?

Indeed, the syntax highlighting in the editor is performed by CubeIDE (ie, Eclipse) - not the toolchain - so doesn't (yet) support C23:

See this recent thread: Defining enum type compiles ok, but STM32CubeIDE flags syntax error.

But that shouldn't affect linking.

Please give more details of the link issues you're seeing?

Does this help ?

As noted in that other thread, it's an Eclipse issue rather than specifically CubeIDE - so I guess Eclipse fora would be the place to find such info?

Yes you are right, it was a wrong formulation used by me: Not actual code linking is breaking but the feature of the IDE to link a variable or constant to the place of definition by ctrl + mouse click.

The other thread you linked (no pun intended) describes exactly the same situation. As CubeIDE is based on Eclipse, I figured some ST member might already know if the next CubeIDE version will use a newer Eclipse build with C23 support in the language server.
