The compiler is gcc 8.3.0 on linux 64-bit.

What happens, as I see it, is xalan generates 'OOXMLFactory_wml.cxx' with endAction method, which is absent in the class definition in the corresponding 'OOXMLFactory_wml.hxx'. I don't understand the source or XSLT enough to either add the definition or decide whether the method is actually needed.

The error messages follow:
