Hi, I've found strange behavior, possibly a bug, but more likely a problem with my understanding. Here's the code:
template<class KEY> class Foo { public: void Baz() {} }; template<class KEY> class Bar : public Foo<KEY> { public: void Bum() { Baz(); } }; (I know it doesn't make much sense, I reduced the problem down to simplest terms). I get an error compiling: [EMAIL PROTECTED]:~/tmp$ g++ -c Foo.C Foo.C: In member function 'void Bar<KEY>::Bum()': Foo.C:11: error: there are no arguments to 'Baz' that depend on a template parameter, so a declaration of 'Baz' must be available Foo.C:11: error: (if you use '-fpermissive', G++ will accept your code, but allowing the use of an undeclared name is deprecated) Can someone tell me why Baz is undeclared here? version: [EMAIL PROTECTED]:~/tmp$ g++ -v Using built-in specs.
