C++ SonarScanner "Cannot run program"

I’m using SonarScanner CLI 5.0.1 to scan C++ for code quality.

I have passed it following parameters:


When I run the scanner, I get following output:

I can confirm that /path/to/myproject/.builddir/.builddir-test-unit-coverage is present and folder and its contents have read permissions for all users.

Any idea what might be causing this?

Hi @Ivan_Ribakov,

This error can mean two things, either:

  • This directory /path/to/myproject/.builddir/.builddir-test-unit-coverage doesn’t exist during the analysis.
  • the other possibility, is that you are on unsupported OS/arch. Are you using Alpine Linux? ARM64? 32-bit arch?


@Ivan_Ribakov, any update?

Sorry, I was unable to reproduce after getting back to this after a while.
