From 8f024a02d7d63315ecc3479f0715e927f48fc91b Mon Sep 17 00:00:00 2001 From: Ronald Oussoren Date: Wed, 23 Nov 2022 11:52:12 +0100 Subject: [PATCH] GH-95283: Add note about compilers in Mac/README.txt (#99506) The build machinery assumes that the compiler that's used to build on macOS includes an SDK that's at least as new as the OS version on the build machine.
