Okay thanks, I also found the solution from a blog somewhere while searching.
It's weird how Apple lay out all of the important things about 64-bit in the docs, but left out this one somewhere that I couldn't find easily. I also ran the script to check for 64-bit compatibility, added the proper #ifdef for it (it's only about data types). 2009/9/18 MATSUMOTO Satoshi <sato...@mac.com>: > Hi, > > > Building 64-bit Preferences Pane... > In response to satoshi on Apr 30, 2009 2:21 PM > I have been trying to make a simple 64-bit Preference Pane on Snow Leopard > buid 10A335.
