[Dune-devel] Vote: Required CMake version 3.1 or 3.13?

[Dedner, Andreas]

Hi, hope everyone is doing well!

I think the boat has sailed on this one. That said, I did check the developer meeting minutes from the last two meetings and can't find any mention that this change will be coming. I do think a change like this should be discussed and voted on in a developer meeting (if it was and I missed it in the minutes then apologies).

That said, since we have all now become experts in online meetings, we could consider putting that to good use and have a developer meeting (an afternoon perhapse) sometime soon?

Best
Andreas

Dear all,

I would also prefer to go for the new version.
Could we hear an argument by those prefering 3.10? Since there is
Ubuntu 20.04 LTS now, maybe this argument has changed?

Best,
Peter

Hi,

personally I don't care much either way.  However, given that

a) the requirements have been changed 4 month ago, and nobody seems to have
   cared until now,
b) I expect students that are able to install Dune master to be able
   to install custom cmake binaries as well
c) I appreciate the modernization work of Simon (and Christoph, Lukas, etc)
   a lot, and I would like to help them,

I vote for the status quo.

Best,
Oliver

Dear fellow Dune core developers,

in May I merged dune-common#200 [1] which bumped the required CMake
version for Dune core modules to 3.13. Roberts want to lower this to
CMake 3.10.
His rationale is, that Ubuntu 18.04 LTS only ships CMake 3.10.

As discussed in [1], I (and some others) want 3.12 for better Python
detection support and 3.13 for an improved library handling, which will
help us to modernize the build system (which we already started).

To get more arguments and much more opinions, please have a look at [1].

>From the discussion I assume that the following people are in favor of 3.10:
Robert

In favor of 3.13 seem to be:
Jö
Markus
Simon
Christoph

>From the following developers I don't have a clear opinion without
interpreting too much:
Peter
Ansgar
Andreas
Christian
Carsten
Dominic
Mario
Oliver

Please cast your vote by commenting to [1] or answering this email. If I
got your opinion wrong or you changed your mind, please vote. You have
two weeks (unit Okt. 13).

Thank you!
Christoph
