There's a number of errors similar to the following: ../../../Tools/TestWebKitAPI/Tests/WTF/WeakPtr.cpp:366:17: error: alias template 'WeakPtr' requires template arguments; argument deduction only allowed for class templates 366 | WeakPtr derivedWeakPtr { derived }; | ^ ../../../Tools/TestWebKitAPI/Tests/WTF/WeakPtr.cpp:91:22: note: template is declared here 91 | template<typename T> using WeakPtr = WTF::WeakPtr<T, WeakPtrImplWithCounter>; | ^ We can add the template parameter explicitly to get those to build. The issue seems to be with the local WeakPtr type alias, which is declared with “using”.
