SDK 10.11 introduces springLoadingHighlight. It is a objective-c property in a protocol. It is marked as NS_AVAILABLE_MAC(10_11), but it exists. As a result, if we build WebKit with 10.11 SDK in Yosemite, the following build failure occurs. /Users/yusukesuzuki/development/Modules/Tools/WebKitTestRunner/mac/WebKitTestRunnerDraggingInfo.mm:35:17: error: auto property synthesis will not synthesize property 'springLoadingHighlight' declared in protocol 'NSDraggingInfo' [-Werror,-Wobjc-protocol-property-synthesis] @implementation WebKitTestRunnerDraggingInfo ^ In file included from /Users/yusukesuzuki/development/Modules/Tools/WebKitTestRunner/mac/WebKitTestRunnerDraggingInfo.mm:1: In file included from /Users/yusukesuzuki/development/Modules/Tools/WebKitTestRunner/WebKitTestRunnerPrefix.h:30: In file included from /Users/yusukesuzuki/development/Modules/WebKitBuild/new-int1/Release/WebKit.framework/PrivateHeaders/WebKit2_C.h:66: In file included from /Users/yusukesuzuki/development/Modules/WebKitBuild/new-int1/Release/WebKit.framework/PrivateHeaders/WKView.h:30: In file included from /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/System/Library/Frameworks/Coco a.framework/Headers/Cocoa.h:13: In file included from /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/System/Library/Frameworks/AppK it.framework/Headers/AppKit.h:15: In file included from /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/System/Library/Frameworks/AppK it.framework/Headers/NSActionCell.h:8: In file included from /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/System/Library/Frameworks/AppK it.framework/Headers/NSCell.h:11: In file included from /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/System/Library/Frameworks/AppK it.framework/Headers/NSText.h:8: In file included from /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/System/Library/Frameworks/AppKit.framework/Headers/NSView.h:18: /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/System/Library/Frameworks/AppKit.framework/Headers/NSDragging.h:101:47: note: property declared here @property (readonly) NSSpringLoadingHighlight springLoadingHighlight NS_AVAILABLE_MAC(10_11); ^ 1 error generated.

I'm sorry, I forgot about this report. This is a supported configuration, and I actually fixed this in another bug. *** This bug has been marked as a duplicate of bug 149389 ***
