Is anything that trusty (1.61 / 1.66) or xenial (1.72) provides in
terms
of cppcheck too old? If yes, the build should not flood the logs with
tons of warnings like it does right now (not a good sign for this
cppversion version...).
Hmm... I prefer to have a fixed version, because results of cppcheck
vary a lot between versions.
Selecting one from a specific Ubuntu release provides you exactly this.
So, unless there is need to go for 1.80, let's go for a packaged version.
Other versions of it have other messages, then I have to redo those
suppressed parameters.
I can do that, but I am not really convinced about the usefulness.
About warnings compiling cppcheck, I just
trust that the cppcheck developers know what they are doing. We cannot
see the compile errors that coverity prints out.

You are right with this one! Will fix this in the next version.

it seems there is still some work needed to fine tune the setting prior
to activating this.
In those other messages complains about some missing includes it does
not need, because they are part of the stl.
I can try to hide those messages.
I only look at those logs if travis writes me an email. So for me they
don't really need them to be pretty, the result is what matters.
So, I don't care about the email report because the web log seems more
complete. Anyway, both should be clean.
So hiding them is better?
Another finding: I'm not sure if we should run all variants for the
coverity scan. They seem to overwrite each other, generating multiple
reports per run. And cppcheck should definitely NOT be run for coverity
builds.
That should not be the case anyway, because this build script is only
called if coverity was not called:
if [ ${COVERITY_SCAN_BRANCH} != 1 ]; then ./.travis-build.sh ; fi
But you are right that coverity is called for each different environment
variable. That should be fixed. Now sure how yet.
You could pass COVERITY_SCAN_BRANCH to the script and filter on one
variant that should be built in that case.
Will do that.
