System Information:
SonarQube Scanner 4.2.0.1873
Java 11.0.3 AdoptOpenJDK (64-bit)
Linux 5.3.0-40-generic amd64
build-wrapper, version 6.3 (linux-x86)
SonarQube 7.9 LTS
I’ve encountered an issue when attempting to make use of the SonarQube scanner for C++ code in conjunction with the Bullseye code coverage tool.
To reproduce
- Makefile to build code using the Bullseye g++ compiler
- This is a symbolic link to their own covc application, which just proxies through to the system g++ whilst generating coverage
- Generate a coverage.xml using Bullseye covxml
- Run the sonar build-wrapper on the same makefile target (And so uses the Bullseye g++ compiler)
- Run sonar-scanner
What we get is the following from the sonar-scanner (However there are times in which this does not occur):

ERROR:
ERROR: Re-run SonarQube Scanner using the -X switch to enable full debug logging.
Due to the fact our build makes use of the Bullseye g++ compiler, when making use of -X
on the sonar-scanner it fails to run as Bullseye’s g++ will error when the -x
is passed through to this.
Potential Workaround
It appears that if I remove the symbolic links, replacing them instead of hard links to the covc binary, the sonar-scanner function works as expected.
I assume that this means the issue is when making use of a symbolic link for your compiler, is this something that is known to cause issues?
