Setup as STM32Cube project fails

[DamianoF]

I'm encountering a persistent issue when setting up an STM32Cube project in VS Code. Even when reverting to a previously working commit or starting a fresh setup from scratch (using the "Setup as an STM32Cube project" button), the process fails.

The following error message appears:

"Cube project discovery CMake configure step failed. Setup might be incomplete. Please check output logs"

I have tested this on two different machines running both Linux and Windows, but the result is the same. Here are the relevant logs:

Hi @DamianoF 

If you are reverting to a previous working commit ensure you do a clean build before discovering the project

If the project clean is not sufficient you can remove the .setting and .vscode from your project then relaunch the discovery.

Hello and thank you for the reply,

obviously I cleaned the build folder and removed the .settings and .vscode folders (which were not tracked with git)

Hi @DamianoF,

Could you show us the errors from the CMake/Build output channel?

Also make sure that, once .vscode/settings.json is created during project setup, it well contains the configuration for cube-cmake tool.

And finally ninja, cmake and gnu-tools-for-stm32 should be part of .settings/bundles.store.json.

I did a mistake on my side and I forgot to add an import to my CMakelists.txt. I am sorry
