This brings up a question I had a while ago, but never asked and about which I forgot. I tried making a 64-bit app in Xcode 3.0 a while ago and set the architectures, as you mentioned, to "ppc64 x86_64". When I ran the app, sizeof(long) was still 4 on a Core2 Duo running Leopard. I found a compiler option called "Use 64-bit Math". After enabling that, sizeof(long) was 8. I was never sure if that was correct behavior, but, as I said, I just forgot about it. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
