<p>Yes, this is how I have understood you. <br>
</p>
<p><br>
</p>
<p>I followed your path and clicked on the webpage and tried to find
our the compiler requirements. It is currently very complicated to
find out:</p>
<p><br>
</p>
<p>Getting started -> Building from Source -> Dependencies
-> Recent Changes -> dune-common CHANGELOG (no information)
<br>
</p>
<p><br>
</p>
<p>That's why my question: what is the best place to put this. We
can put it into the changelog, but it is not so obvious that one
has to look specifically into the dune-common changelog to find
out the compiler requirements for the core modules. This assumes
you already know the modules graph and dependencies.</p>
<p><br>
</p>
<p>How does deal.ii do it? The link on their webpage under current
release to the README with system requirements as first section.
In their git repository there is a quick installation plus a link
to that detailed REMAE spekoen before. So, maybe this is the right
path to follow? We just need to be consistent in our descriptions.</p>

And as i said in my original email the link to the Changelog on
the webpage seemed like a sensible way to avoid duplicating the
information. I don't see why this information could not be added
now to the changelog even it changes again before 2.11 is
released.</div>

<div class="PlainText">Hi again,<br>
<br>
regarding the info on the webpage and the changelog: the
problem was that we have at least 5 places where compiler
requirements are listed and these were (and are still) not
synchronizes. I think, we wanted to reduce this to 1 or 2
places only. That is why the webpage just refers to
another source. This can probably be improved.<br>
<br>
Since the master is the current development version of our
code, the compiler and library requirement for 2.11 might
still change and thus is not fixed in the changelog. The
only thing we can currently guarantee is what the ci
system is testing.<br>
<br>
The question is, where is the best place to list the
requirements, such that we can link to it from the other
places?<br>

Betreff: Re: [Dune-devel] current support gcc version<br>
<br>
Hi Andreas,<br>
<br>
the decision was that we wanted to lift the minimal
versions after the<br>
2.10 version to something that allows working with c++
concepts. This is<br>
gcc >= 10 and clang >= 13. This is also what is
implemented in the<br>
system tests and ci pipelines. It is written, for example,
in the README<br>
of dune-common. There were a couple of MRs proposing and
then<br>
implementing this change, see, for example,<br>
