It can be a little more complicated than that: http://developer.apple.com/DOCUMENTATION/Darwin/Conceptual/64bitPorting/intro/chapter_1_section_1.html

So I’m new here. Also fairly new to Cocoa/Objective-C, although I have fooled around at home with some tiny self-written programs, including one that has balls bouncing around on the screen.

Anyway, how to you “build 64-bit”? Is there a switch somewhere in Xcode for me to flip? If so, just tell me and I’ll do it, so I can join this march into the future. Thanks.

The framework I’m talking about is an open-source Crashreporter. I can’t use the one from Apple (I think a Select/Premier membership is needed) so I use that one.

You may have a point there once Apple ship OS X in a shape where all applications that come with it run in 64-bit mode.

But until that happens, making your application 64bit will mean that you have all the extra overhead of loading the 64bit frameworks just for that application.

As things are today, the only 64bit process I see on my system is httpd which probably doesn’t use the big OS X frameworks. The other is iScrobbler (which for some idiotic reason is shipped as a 64bit application see http://earthlingsoft.net/ssp/blog/2008/02/pictd).

So for the time being I’d rather be conservative with 64bit-ness. There will be plenty of time to adjust for that once Apple move their stuff over. And the advantages of going 64bit seem to be negligible for the vast majority of applications.

@SCARAMANGADO - which framework? Sparkle 1.5 works just fine under both 64-bit and Garbage Collection.

@IVÁN - I’m not trying to cause a flame war, but the writing is on the wall for Carbon. If you don’t port to Cocoa in Snow Leopard +1, it’s likely your app won’t run at all.

I’m talking about a nice framework supporting neither 64-Bit nor the 10.5 garbage-collection.

Oh, it’s another framework, and that doesn’t sopport GCC, too. *ARGH*

Sparkle 1.5 certainly does support 64-bit. 1.1 doesn’t.
