Hi @BerndM
Indeed, in Eclipse, SonarLint will only analyze C++ code when connected to a SonarQube server. And in connected mode, we are using rules configured in the quality profile of the bound project.
There are some rules that can’t be executed in SonarLint. I suggest you read the FAQ to know more. If you still think there is a problem, and SonarLint should report the issue, please give us enough details to investigate: the rule key you are expecting to see, and the code snippet that should produce the issue.
