Hello @bahctr,
The SonarScanner Docker image is meant to be used in a Docker image. But we don’t support the analysis of C or C++ projects in Docker images.
So by “modify your configuration”, I meant not doing the build wrapper with the build nor the analysis in a Docker image.
The “regular” SonarScanner is for everything else: a Linux terminal, a Gitlab CI pipeline script etc…
You can find examples of analysis in GitLab in this repository: SonarSource sample C and C++ projects with SonarCloud or SonarQube analysis configured.
HTH,
Amélie
