Date: Wed, 14 Nov 2007 22:20:27 -0500 From: Calvin Vette Subject: Fix to compile SDL-1.2 SVN on OS X Leopard I found I needed to add a conditional check for Leopard to compile cleanly on 1.2-SVN (20071114): #include <AudioUnit/AudioUnit.h> #ifdef AVAILABLE_MAC_OS_X_VERSION_10_5_AND_LATER #include <AudioUnit/AUNTComponent.h> #endif where there is now just: #include <AudioUnit/AudioUnit.h>
