I've been staring at this error message for the past hour.
When trying to compile the code ...
-------------------------------------
#import <Cocoa/Cocoa.h>
@interface TWInterpreterController : NSWindowController <NSTableViewDelegate>
...
@end
--------------------------------------
the compiler issues the error:
"Cannot find protocol declaration for 'NSTableViewDelegate'"
The import of Cocoa/Cocoa.h causes the import of AppKit/NSTableView.h which contains the protocol definition of NSTableViewDelegate, so I fail to see what's happening here. Googling the error message leads to the advice that all circular/recursive import/include loops be avoided, but I fail to see how one could be happening here.
In versions of NSTableView.h before 10.6 the delegate was not defined as a protocol but as a category on NSObject, so if an older version of the header file were being imported I could understand the message.
But I'm assuming the NSTableView.h that is being imported must be the one that I see when I check under the header files under the Frameworks tab in the Xcode Groups&Files navigator. I do see the older version of NSTableView.h that define the delegate in a category in the directory:
/Developer/SDKs/MacOSX10.5.sdk/System/Library/Frameworks/AppKit.framework/Versions/C/Headers/NSTableView.h
But I'm building with the 10.6 SDK. Is there some mechanism that might be causing the older NSTableView.h to nevertheless get imported?
Thanks,
