[Dune-devel] current support gcc version

[Simon Praetorius]

Hi again,

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.

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.

The question is, where is the best place to list the requirements, such that we can link to it from the other places?

Best,
Simon

Hi Andreas,

the decision was that we wanted to lift the minimal versions after the
2.10 version to something that allows working with c++ concepts. This is
gcc >= 10 and clang >= 13. This is also what is implemented in the
system tests and ci pipelines. It is written, for example, in the README
of dune-common. There were a couple of MRs proposing and then
implementing this change, see, for example,
https://gitlab.dune-project.org/core/dune-common/-/merge_requests/1445

Best,
Simon
