Re: Cant get Garbage Collection to work
Have you tried using Xcode's build settings instead of manually specifying the compiler flag? There might be more to it than just -fobjc-gc-only. no, that's the only option needed if you want to use compiler flags in the long term, it's still worth trying the build setting, just so you can check the build log to see what flags Xcode is using. my guess is that he's changing in the wrong target, or in the wrong place and something is overriding. To double check, he should try to compile from cli -- uL Pragmatist http://blog.ugolandini.com ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

But you're still not saying what the errors actually are. They may not be an indication that there is a problem with GC, but that a different issue has been exposed by turning on GC. For example, you will get nuisance errors like this: malloc: free_garbage: garbage ptr = 0x126b5f0, has non-zero refcount = 1 in the log when you open a window that uses the system template images that IB provides you. AFAIK this is a (harmless) bug in Leopard that will get fixed one of these days, and there is nothing to do in the meantime except ignore the messages. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Cant get Garbage Collection to work
Where do you have GC enabled? My experience has been that you have to set it for each target as the project-level setting gets overridden.

FWIW, I haven't noticed any problem with this on newly-created projects. But Xcode is so unreliable in the area, it's certainly a possibility worth checking. The other thing worth checking, that gets me all the time, is that it's too easy to change a setting only for the Debug/Release configuration you're not actually using. The engineers responsible for Xcode could definitely use a hosing-down by the HIG police water cannons, but that fantasy belongs on a different dev list. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
