template question

Where is the problem in the code below?

The g++ error message is:
(all throwed in the last line)

`Texture' was not declared in this scope
template argument 2 is invalid
expected `{' before '>' token
expected unqualified-id before '>' token
declaration of `class TextureUnit<K>'

--------------------------------------
template<typename K>
class Texture {};

template<typename K>
class TextureUnit : public ObjectPool<K, Texture<K> > {};
--------------------------------------

In case, your question still stands: you have not provided code that
exhibits the problem as the following compiles without trouble

template<typename K>
class Texture {};

template<typename K, typename V>
class ObjectPool {};

template<typename K>
class TextureUnit : public ObjectPool<K, Texture<K> > {};

int main ( void ) {}

Let's talk about people who say they are going to call someone
"up". They don't call them up, they just call them.
