Im getting an "undefined reference" error from the linker step in g.program that "encapsulates" the 3 static member variables The declaration of MyClass::log in the class definition gets C linkage despite the extern "C", because static class members simply dont exist in C. But for some reason, the definition of MyClass::log outside the class definition gets C linkage, which doesnt make much sense to me. A static data member must be defined outside the class body even if it is initialized within the class body, but no diagnostic is required if the definition is missing. It turns out that some releases do emit references to the missing symbol, while others optimize it away. At least on g 4.2.4.
