Hi all,
I have this following error
In test.h
=============== =============== =============
#include <iostream>
#include <cstddef>
#include <utility>
template<typena me Tclass myclass;
template<typena me Tstd::ostream& operator<< (std::ostream&, const
myclass<T>&);
template <typename Tclass myclass {
public:
friend std::ostream& operator<< <T(std::ostream & os, const
myclass<T>& var1);
....
...
...
private:
struct mysubclass
{
int par1;
int par2;
};
};
#include "myclass.te m"
=============== =============== ===============
In myclass.tem,I have
=============== =============== =============== ==
#include <cassert>
#include <algorithm>
template<typena me T>
std::ostream& operator<< (std::ostream& values, const myclass<T>&
var1)
{
typename myclass<T>::mys ubclass *current;
current->par1=89;
............... ............... ...
............... ............... ......
}
When I compile I get the error
In myclass.tem
error: ‘par1’ was not declared in this scope
What am I doing wrong.How can solve this.
Cheers,

Well, I don't see any error with this code,
except a runtime error, you didn't initialize the pointer "current".
and VC2005, GCC4.3, Comeau Online compiles file.

What complier are you using? What is the exact error message?
And the exact code which triggers it?
Deleting the "..." lines in your code and adding a return to the
operator<<, it compiles with all of the compilers available to
me (Sun CC, g++ and VC++), including if add code to instantiate
the function.

Thanks for the help guys.
Yeah.The pointer is to be initialised.
The exact error message is
myclass.tem: In function ‘std::ostream& operator<<(std: :ostream&,
const myclass<T>&)’:
myclass.tem:61: error: ‘par1’ was not declared in this scope
myclass.tem:64: error: ‘par2’ was not declared in this scope
cc1plus: warnings being treated as errors
I am trying to compile it in g++.
I am stumped.

With what code? The code you posted cannot compile, as such,
because of the .... lines. Deleting those, it *does* compile
with g++ (both versions 4.1.0 and 3.4.0). So please post an
exact example (copy/pasted) of the code which doesn't compile,
with the exact error message you get, and which version of the
compiler you are using.

Thanks for you support James.Yes, you were correct.The problem was
with the way I was calling the classes.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
