Must-share information (formatted with [Markdown](https://commonmark.org/help/)):

- which versions are you using  
SonarQube-10.2.1.78527,  
build-wrapper-macosx-x86,  
sonar-scanner-5.0.1.3006-macosx,  
M2 macOS sonoma 14.1.1

- how is SonarQube deployed: GCP

- what are you trying to achieve  
Execute analysis by sonarscanner and send the analysis results to sonarqube, which is located on GCP.

- what have you tried so far to achieve this  
Verify that the clean build succeeds with the command “xcodebuild -workspace \*\* -scheme \*\*”.  
But that the command “build-wrapper-macosx-x86 --out-dir build\_wrapper\_output\_directory xcodebuild -workspace \*\* -scheme \*\*” and "sonar-scanner   
-Dsonar \*\*"gets the following error and ends in analysis failure.

Hey there.

It sounds like you have the process right. Can you zip up your build-wrapper output directory and share it?

Thanks for your help.  
The build-wrapper output directory contains two files.Personal data are Masked.

Thanks.

It doesn’t look like `xcodebuild` is _doing_ all that much (like compiling code). Do you expect to analyze C/C++/Objective-C files, or, for example, only Swift files (in which case the build wrapper is not needed)?

My project uses obejective-c and swift.So I believe that build wrapper is necessary.

Hi @Take ,

I am sending you a private message where I can collect more information about your project.

Hi @Take ,

to sum up our private conversation, the build-wrapper is not able to capture the compiler invocations from Xcode 15, I created a ticket for that: [[CPP-4941] - Jira](https://sonarsource.atlassian.net/browse/CPP-4941).

We plan to solve that throughout the year. In the meantime, the compilation database can be used to run the analysis, instructions provided in the ticket.

For more information about the compilation database, please refer to the SonarQube documentation:

> **[C/C++/Objective-C](https://docs.sonarsource.com/sonarqube/latest/analyzing-source-code/languages/c-family/#using-compilation-database)**
>
> C/C++/Objective-C analysis is available starting in Developer Edition.

Hey @Take,

If you didn’t see – last year we introduced support in SonarQube Server for a feature called C/C++ AutoConfig! Removing the question of using a compilation database altogether.

> [@C and C++ AutoConfig for SonarQube](https://community.sonarsource.com/t/c-and-c-autoconfig-for-sonarqube/117344):
>
> We have big news for our dear C and C++ SonarQube users. Configuring the analysis requires some skills; at times, it can get technical and tedious, with a few known caveats. We unleashed the talent of our mighty engineers, and they made our C and C++ analyzer smart enough to configure itself. Hence the name AutoConfig. As a result: No need to worry about compiler support No need to worry about build-wrapper or compilation database No need to know anything about the project to configure, nor C…

This is available in SonarQube Server _v10.6+_, although you should really target at least _v2025.1_.

All said, you can continue to reference the workaround in the ticket Massimo mentioned.
