Re: [4diac-dev] Changing C++ standard requirements for FORTE
|
Hi,
the reason was to make as far as a jump as reasonable, but you have a good point here.
We will switch to C++17 then with the perspective of switching to C++20 in about 6 months after the next release.
Best regards,
Martin

While I applaud the change, is there a specific reason you want to switch to C++20 in particular? On paper, support may be good, but in reality the more interesting features of that standard are only supported by the very latest versions. We should not shut out mainstream compilers that are still in active support (e.g. GCC 9).
C++17 support, on the other hand, is very mature in all recent
compilers. If there are no specific C++20 features you are thinking of, I would suggest requiring C++17 for now, with the stated intention to upgrade this requirement in the future.
