C++ code generation

[johnw@wessex]

I'm trying out the demo of Enterprise Architect.
I created a class diagram containing a private static integer variable and then generated the C++ source code.



///////////////////////////////////////////////////////////
//  Class1.h
//  Implementation of the Class Class1
//  Created on:      08-Feb-2005 09:39:27

#if !defined(EA_CF70D464_4571_408e_AD98_FC90F6E31E1F__INCLUDED_)
#define EA_CF70D464_4571_408e_AD98_FC90F6E31E1F__INCLUDED_

class Class1
{
public:
Class1();
virtual ~Class1();

private:
static int some_variable;
};

#endif // !defined(EA_CF70D464_4571_408e_AD98_FC90F6E31E1F__INCLUDED_)

///////////////////////////////////////////////////////////
//  Class1.cpp
//  Implementation of the Class Class1
//  Created on:      08-Feb-2005 09:39:27
///////////////////////////////////////////////////////////

#include "Class1.h"

//**** THIS LINE IS MISSING FROM THE GENERATED SOURCE ****
int Class1::some_variable;
//*************************************************

Class1::Class1(){

}

Class1::~Class1(){

}

Without the missing line the code is un-compileable!

Any thoughts?

What do you mean by un-compilable? Why are you missing this line? Did you include this attribute in Class1 and it's not generated?

What do you mean by un-compilable?

A static variable declared in a class must be defined.

class MyClass
{
public:
   static int var;
};

int MyClass::var;

Did you include this attribute in Class1 and it's not generated?

Correct

Appearently it is a known issue and you must import this XML for it to work.
