problem w/ nested templatized classes

its not really a nested templatized class, but a templatized class that has another class inside it.

Code:

---

template <class T>
class Outer {
  public:
  ...
  class Inner {
    ...
  };
};

#include "myclass.cpp"

---

I defined the methods in "Inner" like this

template<class T>
void Outer<T>::Inner::method1(...) {
...
}

when I compile and link this code, I get an unresolved external error for all the methods in "Inner", but none for "Outer"

Is there something wrong with my syntax?

Not that I can see.

Check syntax for this line you posted.

Code:

---

template<class T>
void Outer<T>::Inner::method1(...) {
...
}

---

Try this solultion.

Code:

---

template<class T>
void Outer<T>::Inner()
{
  Inner::method1();
}

¿Que?
What is that supposed to do?

I think the code he posted looks correct. The problem could be an old compiler or something not in the posted code.

Actually im using visual studios 6.0 (i always forget to mention that). Guess im just gonna have to rewrite it (not that big of a deal, the class was already written, i just now have to "templatize it")

I believe ClownPimp wanted to define a member function of an inner class.

Is there a specific reason why you want to implement nested classes? I recommend inheritance for simple designs.

I have to do it this way. Instructor said so.

Try to use a different compiler. For example, use a Linux lab and compile the source code using GNU C++.

tried that, i but got a whole bunch of errors in my other source, and since the problem only surfaces when I try to link, i will have to fix the other errors first (i hate it when code works fine on MSVC but on gcc it theres tons of errors). I guess Ill have to write some sort of skeleton to see if it will link correctly...
