Bug 108321 – [Qt][Mac] r141037 broke the build

• Status: RESOLVED
• Resolution: DUPLICATE
• Component: New Bugs

[Zoltan Arvai]

It seems r141037 broke Qt Mountain Lion with changes in WebKit2/Platform/CoreIPC/mac/ConnectionMac.cpp.

Because at this time there was a missing header problem, I can show error message from a later build:

or

and other similar errors.
