SonarScanner abort execution with java error Unsupported value of _cplusplus macro: 202100L

SonarQube Server / Community Build
1

Hello,

I am trying to execute sonar scan on C++23 code

I work with the following configuration:
SonarScanner 5.0.1.3006
Java 17.0.7 Eclipse Adoptium (64-bit)
SonarQube server 9.9.2.77730
CFamily plugin version: 6.41.1.62265

Even the C++23 is marked supported I have the following Java exception:

Is there a way to not end the scan even the unsupported value __cplusplus macro: 202100L?

Thanks for your help,

Hey there.

SonarQube v9.9 LTS does not support C++23 (docs)

However, it is available in SonarQube v10.5, which was released yesterday! (the website says 10.4, but the link is to 10.5, we’re in the process of fixing it)

Hello Colin,

Thank you for your answer, I will upgrade my sonarqube instance.

Hi Colin,

What is the lowest version of SQ client (i.e. sonar-scanner binary) that supports C++23?

Thank you
Gene

Hi @GeneG,

You’ve resurrected a 6-month-old thread. Per the FAQ, please don’t do that. Normally, I’d ask you to create a new thread with all your details. But this one’s easy: we don’t maintain a compatibility matrix. Install the latest SonarScanner.

 
HTH,
