I just subscribed to this list but since I've been using the archived search and found nothing about this I'm going to post it... I hope this isn't some kind of 'dead horse' issue and people 'hate it' when it's brought up... :)
Try this with your system.
- Launch Xcode and create a 'new cocoa application'
- Compile it (yea it builds)
Now look at the build session where you can see gory gcc details...
In that line should see something like -mtune=G5 (well I do anyway and I'm not even on a G5) and to top it off, under Project Settings -> Build it clearly reads PowerPC G4 [-mtune=G4] (so why is it building with G5?!?!?! On top of that.... If I set it to say '-mtune=G3' it doesn't seem to matter one bit... also I think other things in 'build settings' might be ignored as well but until I test I can't be sure....
Now I've checked this on my dual 1.25 G4 MDD and my PowerBook and both are doing the same thing.
Both had 2.2.1 installed but in testing on my desktop I've even done a full uninstall (running the perl script) and reinstalled 2.2 (same problem) then did and uninstall and then a reinstall of 2.2.1 (still same problem).
I've also created a 'new user' on my system (never ran Xcode - no baggage - etc) and tried it from that account... (same thing)
Could anyone else confirm this is happening to them? If not then I'm clearly going insane!! :)
