Hello, Thank you for reporting this building issue. This problem is already resolved in the libYafaRay v4.0 pre-alpha codebase, which is using the C++17 standard. The old YafaRay v3.5.1 is no longer being developed.

DavidBluecame commented 8 months ago

That said, it is true that libYafaRay 4.0 pre-alpha code is still too unstable for any distros. In the mean time please feel free to keep your patch in the distro to build YafaRay v3.5.1, as its codebase will (almost certainly) not change.
