I'm using WebKit revision 43137, Mac OS X 10.5.6, Xcode 3.1.2 I built a test Cocoa application linked to WebKitBuild/Debug/WebKit.framework. I got 24 build warnings: "'weak_import' attribute ignored". All 24 build warnings are for @property declarations with the AVAILABLE_IN_WEBKIT_VERSION_4_0 macro. On my system, the following definition applies: #define AVAILABLE_IN_WEBKIT_VERSION_4_0 WEAK_IMPORT_ATTRIBUTE Here is the complete list of warnings: WebKit/WebKitBuild/Debug/WebKit.framework/Headers/DOMText.h:35: warning: 'weak_import' attribute ignored WebKit/WebKitBuild/Debug/WebKit.framework/Headers/DOMDocument.h:81: warning: 'weak_import' attribute ignored WebKit/WebKitBuild/Debug/WebKit.framework/Headers/DOMElement.h:53: warning: 'weak_import' attribute ignored WebKit/WebKitBuild/Debug/WebKit.framework/Headers/DOMElement.h:54: warning: 'weak_import' attribute ignored WebKit/WebKitBuild/Debug/WebKit.framework/Headers/DOMElement.h:55: warning: 'weak_import' attribute ignored WebKit/WebKitBuild/Debug/WebKit.framework/Headers/DOMElement.h:56: warning: 'weak_import' attribute ignored WebKit/WebKitBuild/Debug/WebKit.framework/Headers/DOMElement.h:57: warning: 'weak_import' attribute ignored WebKit/WebKitBuild/Debug/WebKit.framework/Headers/DOMCSSStyleSheet.h:38: warning: 'weak_import' attribute ignored WebKit/WebKitBuild/Debug/WebKit.framework/Headers/DOMHTMLButtonElement.h:38: warning: 'weak_import' attribute ignored WebKit/WebKitBuild/Debug/WebKit.framework/Headers/DOMHTMLButtonElement.h:42: warning: 'weak_import' attribute ignored WebKit/WebKitBuild/Debug/WebKit.framework/Headers/DOMHTMLDocument.h:43: warning: 'weak_import' attribute ignored WebKit/WebKitBuild/Debug/WebKit.framework/Headers/DOMHTMLDocument.h:44: warning: 'weak_import' attribute ignored WebKit/WebKitBuild/Debug/WebKit.framework/Headers/DOMHTMLIFrameElement.h:47: warning: 'weak_import' attribute ignored WebKit/WebKitBuild/Debug/WebKit.framework/Headers/DOMHTMLInputElement.h:46: warning: 'weak_import' attribute ignored WebKit/WebKitBuild/Debug/WebKit.framework/Headers/DOMHTMLInputElement.h:48: warning: 'weak_import' attribute ignored WebKit/WebKitBuild/Debug/WebKit.framework/Headers/DOMHTMLInputElement.h:56: warning: 'weak_import' attribute ignored WebKit/WebKitBuild/Debug/WebKit.framework/Headers/DOMHTMLInputElement.h:62: warning: 'weak_import' attribute ignored WebKit/WebKitBuild/Debug/WebKit.framework/Headers/DOMHTMLSelectElement.h:43: warning: 'weak_import' attribute ignored WebKit/WebKitBuild/Debug/WebKit.framework/Headers/DOMHTMLSelectElement.h:46: warning: 'weak_import' attribute ignored WebKit/WebKitBuild/Debug/WebKit.framework/Headers/DOMHTMLTextAreaElement.h:40: warning: 'weak_import' attribute ignored WebKit/WebKitBuild/Debug/WebKit.framework/Headers/DOMHTMLTextAreaElement.h:46: warning: 'weak_import' attribute ignored WebKit/WebKitBuild/Debug/WebKit.framework/Headers/DOMEvent.h:48: warning: 'weak_import' attribute ignored WebKit/WebKitBuild/Debug/WebKit.framework/Headers/DOMEvent.h:49: warning: 'weak_import' attribute ignored WebKit/WebKitBuild/Debug/WebKit.framework/Headers/DOMEvent.h:50: warning: 'weak_import' attribute ignored

I think this is actually a compiler bug, as slightly newer versions of GCC have been fixed to not warn on this code. I wonder if there's any way we can work around it for affected compiler versions.

We no longer support such old Xcode.
