In the steps of setting up CI builds on your gitlab server, I can't seem to find information on how to set up the detection of compiler warnings. Example build output:
[100%] Building CXX object somefile.cpp.o
/home/gitlab-runner/builds/XXXXXXX/0/group/project/src/somefile.cpp:14:2: warning: #warning ("This is a warning to test gitlab") [-Wcpp]
#warning("This is a warning to test gitlab")
^
However the build result is success instead of warning or something similar. Ideally the results wuold also be visible on the merge request on the feature (and block the merge if possible).
I can't imagine I'm the only one trying to achieve this, so I am probably looking in the wrong direction. The 'best' solution I found is to somehow manually parse the build output and generate a JUnit report.
How would I go about doing this without allowing the build job to fail, since I would like the job to fail when compiler errors occur.
