Still it would be good to clarify the g++ requirements - or should 7.3 work?<br>

<div>Hi Andreas,</div>
<div>Probably an outdated CI config. Since <a href="https://gitlab.dune-project.org/core/dune-common/-/merge_requests/786">https://gitlab.dune-project.org/core/dune-common/-/merge_requests/786</a> it works for me. I rebased and force-pushed my branch and all
went green.</div>
<div><br>
</div>
<div>Bye</div>
<div>Christoph</div>

In dune-common/README.md it says >=7 but for a few days now std::optinal is used in dune-common and that seems to fail with 7.3</div>
