I am having trouble compiling an app for 64 bit and wonder if there's a bug or if I'm clueless (or both...).
I took a working app, compiled it 64-bit, and found it hung. OK. But with a bit more digging I discovered the following (Xcode 3.0 on a CD2):
You can get a very boring app by doing the following:
- start xcode.
- make a new project -- a cocoa app.
- press build and go.
But if you change the app's Architectures to 64-bit (and make no other changes), do a Clean All, and then press build and go, you get an app stuck in the SBBoD (about which more below). The actual problem is a bus error in AppKit: InstallEventLoopTimerInternal, which seems kind of basic to be having a null pointer passed in.
Do you mean change it to 4-way universal or _just_ 64-bit. Changing the basic Cocoa template app to 4-way works fine for me. So I tried 64-bit universal (i386/ppc) and that works too. So, while my install is just one install and anecdotal evidence, it works for me. this might mean it might be some kind issue with your setup or system.

GDB is also acting weird.
The debugger should catch this but isn't -- it just sits there patiently. But if you set a breakpoint on main, start the app, and then continue it from the breakpoint, gdb sees the trap correctly.
Anyway:
1 - Am I doing something wrong? or...
2 - are these known issues? or...
3 - should I file some reports?
I couldnt find any mention on the web -- and it's hard to believe that 64-bit apps don't work since it's a much-touted feature that presumably people are trying to use.
Thanks,
