Re: [4diac-dev] Migrating forte to +11
|
Hi all,
we just had an issue, that a 4diac user has to use an old compiler. As I do not see a compelling reason to upgrade FORTE Core to C++11 or 14, I would suggest to stay on the current standard to widen the user base.
Best regards,
Martin

It would be interesting to know which compilers are affected. I think it makes a difference if it's a vendor-specific compiler with no upgrade option or just older versions of well-known compilers.

Depending on the above question, I would go as far as moving straight to
C++17. It is the last small upgrade in the C++11 era and the core
features are well supported by the major compilers by now. Speaking of Linux, there is probably no distribution anymore that is still in its support life cycle and does not have a C++17 compiler.
Most importantly, C++17 would give us std::variant, which could simplify the ANY type a lot and make it more type safe, while keeping its efficiency.
C++20, on the other hand, is definitely too new. Coroutines might be an
amazing way to simplify event queues and execution threads, but it will probably take a long time until this appears in compilers for more exotic platforms.
