Does this line exist in the definition of PublicTON?
AsnType *PublicTON::Clone() const;
mycsta2.h in the PublicTON class there is this line:
AsnType *Clone() const;
Here is the full code (well for this class).
mycsta2.h file has:
class PublicTON: public AsnType
{
public:

unknownCid = 0,
internationalCid = 1,
nationalCid = 2,
networkspecificCid = 3,

abbreviatedCid = 5
};
enum ChoiceIdEnum choiceId;
union

IA5String *unknown;
IA5String *international;
IA5String *national;
IA5String *networkspecific;
IA5String *subscriber;
IA5String *abbreviated;
};
PublicTON() {Init();}
PublicTON(const PublicTON& that);
public:
virtual const char * typeName(void) const { return "PublicTON"; }
void Init(void);
virtual ~PublicTON() {Clear();}
void Clear();

PublicTON &operator = (const PublicTON &that);
void BDecContent (const AsnBuf &b, AsnTag tag, AsnLen elmtLen, AsnLen
&bytesDecoded/*, s env*/);
void BDec (const AsnBuf &b, AsnLen &bytesDecoded);
};
mycsta2.cpp has:
PublicTON::PublicTON(const PublicTON &that)
{
Init();
*this = that;
}
void PublicTON::Init(void)
{
// initialize choice to no choiceId to first choice and set pointer to NULL

and the mycsta2.h file #include "asn-incl.h" which has AsnType class like
this:

virtual const char * typeName(void) const { return "AsnType"; }
#if META

virtual const AsnTypeDesc *_getdesc() const;
virtual AsnType *_getref (const char *membername, bool create=false);
private:

Hello
I am getting this compile error:
error C2259: 'PublicTON' : cannot instantiate abstract class due to
following members: csta2less.h(1755) : see declaration of 'PublicTON'
Class is like this:
class PublicTON: public AsnType
Does this line exist in the definition of PublicTON?
AsnType *PublicTON::Clone() const;
...
How do I fix this problem?
Not enough code to see. We can only guess.
Post a complete and compilable chunk o code that demonstrates your
problem. (if the suggested fix above does not work).
