I’m getting an odd linker error:

Ld /Users/jerry_wong/dev/squeakie/build/Debug/squeakie.saver/Contents/MacOS/squeakie normal i386 cd /Users/jerry_wong/dev/squeakie /Developer/usr/bin/gcc-4.0 -o /Users/jerry_wong/dev/squeakie/build/Debug/squeakie.saver/Contents/MacOS/squeakie -L/Users/jerry_wong/dev/squeakie/build/Debug -F/Users/jerry_wong/dev/squeakie/build/Debug -filelist /Users/jerry_wong/dev/squeakie/build/squeakie.build/Debug/squeakie.build/Objects-normal/i386/squeakie.LinkFileList -framework Cocoa -framework ScreenSaver -arch i386 -bundle -mmacosx-version-min=10.5 -isysroot /Developer/SDKs/MacOSX10.5.sdk Undefined symbols: “.objc_class_name_QCCompositionLayer”, referenced from: literal-pointer@__OBJC@__cls_refs@QCCompositionLayer in squeakieView.o ld: symbol(s) not found collect2: ld returned 1 exit status

I have included Quartz/Quartz.h, and the compiler doesn’t complain about an undeclared class when declaring the QCCompositionLayer pointer, but for the life of me I cannot figure out why the linker is having problems with this.

Below is the relevant chunk of code

#import <Cocoa/Cocoa.h> #import <Quartz/Quartz.h>

@implementation squeakieView

… some stuff here

• (void)startAnimation { [super startAnimation];

  QCCompositionLayer *root_layer = nil; root_layer = [QCCompositionLayer compositionLayerWithFile: [[NSBundle mainBundle] pathForResource:@”purpleclouds” ofType:@”qtz”]];

  [self setLayer:root_layer]; [self setWantsLayer: YES]; }

Thanks in advance!

I don’t see -framework Quartz anywhere in that ld step, only -framework Cocoa and -framework ScreenSaver.
