Hello,
I'm new to using the Vehicle Dynamics Blockset, and I'm following the Configure Virtual Vehicle Setup Guide. However, whenever I attempt to run the scenario, I encounter the following error message:
### Searching for referenced models in model 'ConfiguredVirtualVehicleModel'.
### Found 12 model reference targets to update.
### Starting serial model reference simulation build.
Please download a supported version of Xcode at /Applications/MATLAB_R2024b.app/rtw/c/tools/macsdkver.pl line 27.

I’ve tried uninstalling and reinstalling Xcode, but this hasn't resolved the issue, and I can’t find anyone with a similar problem either.
Are there any suggestions?
Thank you!

Hi @N1XKP,
The error mentions that math.h is not found. This usually means the SDK path is incorrect or incomplete. Ensure that the SDK path set in your environment is correct. You can check and set it in your terminal:
export SDKROOT=$(xcrun --sdk macosx --show-sdk-path)
It also suggests that you might not have a supported version of Xcode. Could you please verify this for your MATLAB release using this portal? https://www.mathworks.com/support/requirements/supported-compilers-mac.html
If none of the above works, you can manually find and add the math.h file by opening the Model Configuration Parameters. To do this, go to the Modeling tab and look in the Setup section, or simply press Ctrl+E. For more details, check out this documentation link: Include headers - MATLAB & Simulink
