[Interest] Build Qt Source (mac): 'make' immediately hits an error ?

[David Skoland]

Hi,

It looks like the source is expecting C++17, but that wasn’t included in the compiler flags, I’m guessing.

Which version of Qt5 is this? May I also ask why you want to compile from git?

Cheers,

David Skoland
