Scanner Bullseye odd error

Hello,
SonarQube Scanner 3.3.0.1492
Java 1.8.0_121 Oracle Corporation (64-bit)
Linux 3.10.0-693.11.6.el7.x86_64 amd64

We recently upgrade SQ from 6.7.6 to 7.6 and this one problem I can not find any reference or clues how to resolve.
This is a C++ project being scanned with SonarQube Scanner for Jenkins 2.8.1

Everything looks fine until near the end and we get this message from debug

DEBUG: Probing compiler: [/opt/BullseyeCoverage/bin/covc, -x, c++, --std, gnu++1z, -v, -dM, -E, -]

Has anyone seen a message like or can offer any tips? Thank you very much.

I found the problem. It was the order of elements in my PATH.
Bullseye/bin was up front, and real compilers were all behind. I moved bullseye to the rear, and now sonar is finding the true compiler (g++) correctly.

Thanks the gods… /facepalm

It turns out this is not a solution. With bullseye at the back of the path, the coverage files are not created.
I think this is an issue with build-wrapper remember the symlinks that bulleyes creates when calling cov01 and then when it analyzes the bw-output, instead of following that to g++ it’s using covc instead.

Hi @ChrisC,

could you please give us a bit more information?

  • version of bullseye
  • sonar-scanner output log
  • build-wrapper.log
  • build-wrapper-dump.json

Hi @mpaladin,
I’ve tried several ways with different versions. The only pieces I have not rolled back on are the sonarserver and cfamily plugin. Going back on scanner, build-wrapper, or sonar jenkins plugin, did not change the behavior.

BullseyeCoverage Compile C++ 8.14.4 Linux-x64

Here the summary of actions being done.
Broken Build Once –
devtoolset-7/enable
Set PATH with Bullseye
cov01 -1
build-wrapper-linux-x86-64 --out-dir ${WORKSPACE}/bw-output make -j
covxml --file $COVFILE --output bsout-cov.xml
Unset Bullseye in PATH
Execute Sonar Plugin

error: unknown option “-x”

Have to Build Twice –
devtoolset-7/enable
Set PATH with Bullseye
cov01 -1
make -j
covxml --file COVFILE --output bsout-cov.xml Unset Bullseye in PATH build-wrapper-linux-x86-64 --out-dir {WORKSPACE}/bw-output make -j
Execute Sonar Plugin

Probing compiler: [/opt/rh/devtoolset-7/root/usr/bin/g++, -x, c++, --std, gnu++1z, -v, -dM, -E, -]

What appears to be happening is, for Bullseye to work, it must be pathed in front, so that this link takes effect
/opt/BullseyeCoverage/bin/g++ -> covc

Somewhere, sonar is now saving this variable and using it instead of finding the real g++ in path. I think. I’ll try to get those logs file you ask for. They probably need to be scrubbed before I can share.
Thanks,

Hi @ChrisC,

I believe you are affected by CPP-1853. In order to confirm that could you please share with me the build-wrapper.log and build-wrapper-dump.json files?

Hi,
The build-wrapper log and json are quite large, and contain much internal information. Is there something I can look for in particular?

Hi @ChrisC,

you can compress them and share them with me privately.
