c++ compiler ( Old & New Version ) Friend Function problem

Rameshwar Miniyar — Fri, 11 Aug 2006 06:11:26 GMT

I am having Friend function problem in my Code. I have three files ( One C++ & two header files )

VIL >ls
CUc060XmlRequest.h CXmlConverter.C CXmlConverter.h

VIL:: >cat CUc060XmlRequest.h
#include
#include "CXmlConverter.h"

class CUc060XmlRequest
{
friend CXmlConverter::CXmlConverter();
friend CXmlConverter::CXmlConverter();
public:
protected:
private:
static void initXmlTagNames();
static void delXmlTagNames();
};
inline void CUc060XmlRequest::initXmlTagNames()
{
}
inline void CUc060XmlRequest::delXmlTagNames()
{
}

VIL: >cat CXmlConverter.C
#include
#include "CUc060XmlRequest.h"
#include "CXmlConverter.h"

CXmlConverter::CXmlConverter()
{
CUc060XmlRequest::initXmlTagNames();
}
CXmlConverter::~CXmlConverter()
{
CUc060XmlRequest::delXmlTagNames();
}

VIL: >cat CXmlConverter.h
#include
class CUc060XmlRequest;

class CXmlConverter
{
public:
CXmlConverter();
virtual ~CXmlConverter();
protected:
private:
};

VIL: >c++ *.C
"./CUc060XmlRequest.h", line 6.12: The attributes "friend" are not allowed.
"./CXmlConverter.h", line 4.7: CCN5403 (S) "class CXmlConverter" is already defined.
CCN0793(I) Compilation failed for file ./CXmlConverter.C. Object file not created.

Please help me to resolve the error "the attributes "friend" are not allowed. I am not able to resolve this. I am upgrading my compiler version from V2R10 to V1R2. It used to work for old compiler. Semantics for friend declaration have changed for new compiler.

Hi,
Would you not require the term class between friend and the class name as CXmlConverter is a class, as you would need void or int or ... if it was a function ?

See have a look at:
http://www.codersource.net/cpp_tutorial_friend.html

The second (already defined) error would come from the inclusion of CXmlConverter.h both in CXmlConverter.C and CUc060XmlRequest.h.
