[Dune-devel] current support gcc version

[Ospina De Los Rios, Santiago]

Hi Andreas,


What's the error about? Are we talking about the SFINAE concepts by Carsten or the C++20 concepts? The C++20 concepts in DUNE are marked as experimental and conditionally included depending if you have a compiler with concepts support. This is partially because version 2.10 is meant to be C++17 compatible. Is maybe this check failing and the headers included in your code?


Best,

Santiago

Subject: [Dune-devel] current support gcc version

Hi.
I'm having difficulties compiling current dune sources with g++ 9.4 on an older system that I have.
The issue is the concepts used in dune-common.

I was wondering what the current lowest version for g++ is? On the webpage it says to look into the changelog (very sensible) but there I can only find that g++ >= 9 should work for 2.10 but nothing newer than that. Is there a changelog entry missing or did I miss it?

Hope everyone is well
Andreas
