Bug 63629 – [Symbian] Fix link error while building with RVCT 2.2 compiler

• Component: WebCore JavaScript
• Status: RESOLVED WONTFIX

[Stanislav Paltis]

While linking QtWebkit with RVCT2.2 compiler, I observe the following errors:
Error: L6218E: Undefined symbol WTF::RefCounted<WebCore::MediaQueryList>::operator delete (void*) (referred from JSMediaQueryList.o).

Error: L6218E: Undefined symbol WTF::RefCounted<WebCore::ArrayBuffer>::operator delete (void*) (referred from JSFileReaderSync.o).

Error: L6218E: Undefined symbol WTF::RefCounted<WebCore::InjectedScriptHost>::operator delete (void*) (referred from JSInjectedScriptHost.o).

Error: L6218E: Undefined symbol WTF::RefCounted<WebCore::ScriptCallStack>::operator delete (void*) (referred from JSConsole.o).

Error: L6218E: Undefined symbol WTF::RefCounted<WebCore::Storage>::operator delete (void*) (referred from JSStorage.o).

Error: L6218E: Undefined symbol WTF::RefCounted<WebCore::CounterNode>::operator delete (void*) (referred from RenderCounter.o).

If building with RVCT4.0 compiler, build is successful.

The problem is that RVCT2.2 has a bug where it does not export automatically destructors for templated objects.

I'm confused why this is needed?  Why do we need a virtual destructor?

Please link to the symbian compiler bug, if this is indeede a compiler bug.  We need to know when we can remove this code.

I could not find actual compiler/linker bug, but it seems to happen only in RVCT 2.2 compiler. It works fine if we are using RVCT 4.0 compiler.
Direction is to move from using RVCT 2.2 and use RVCT 4.0 instead. Let me know what you want me to do.

Closed as WONTFIX - see https://lists.webkit.org/pipermail/webkit-qt/2011-October/001979.html. Symbian was the only port requiring RVCT 2.2.
