Bug 189370 – QuickLook.mm and QuickLookSoftLink.mm must never be built in the same unified source file

• Status: RESOLVED
• Resolution: DUPLICATE
• Component: Tools / Tests

[Daniel Bates]

Today when I re-built WebKit after removing file PlatformEventFactoryIOS.mm from the list of files that are compatible with unified sources (Source/WebCore/SourcesCocoa.txt) my build failed with the following compile error:

[[

The error indicates that QuickLook.mm and QuickLookSoftLink.mm cannot be built in the same unified source file.

Why not annotate with @no-unify?
