- Please help:
-
- I have an abstract class Foo with many virtual functions, from which I have
- derived class FooBar. Everything compiles fine on cfront 2.x
- but I get a linking error:
-
- ld: Undefined symbol
- ___vtbl__21FooBar
-
- Now, I think this means there is a problem with my virtual functions,
- but is it obvious to anyone else what is wrong? If I feed the ___vtbl...
- symbol into "dem", it just spits the same thing back out.
-
- Any suggestions appreciated.
