SonarQube failed to analyze C++ project,

It seems to be Alpine Linux based? We don’t support Alpine Linux because we rely on glibc.

I have also found this old thread with the same issue you are facing, so this confirms it is an issue with musl.

I have linked this conversation to the Jira ticket to helps us record the traction musl has.

For the moment being, I can only suggest using a container based on a distribution that uses glibc.
