Comment (by Samuel Cupp):

Sorry for not responding to this promptly. I do not have a complete list of machines that people are currently using. However, I know for sure people are using Deep Bayou, the INL machines, and Falcon. It looks like Falcon has gcc 12, which I believe has all of the '17 standard. Can you confirm what version of gcc is the minimum for CarpetX currently?

I don’t know what machines the RIT group is using, but it sounded like several of their machines probably don’t have access to C++17 (or anything beyond like 2011…).

I agree with Roland that it would likely be untenable to require C++17 by default to compile the toolkit.
