No appropriate default constructor

[NoNickName]

Here's what I've got, essentially:

main()
{
class derClassA *dCA;
dCA = new(derClassA);
}

class derClassA
{
public:
derClassA(void);
....
}

derClassA::derClassA(void)
{
}
....

Try to compile, I get "No appropriate default constructor".

Any thoughts?

Thx.

I would suggest posting what you have exactly. Somewhere in going from
what you have exactly to to what you have 'essentially' you have lost
the cause of your error.

Some errors below but I don't think any of these are the problem you are
complaining about.

main()
int main()
{
class derClassA *dCA;
derClassA* dCA;
dCA = new(derClassA);
dCA = new derClassA;
}

class derClassA
{
public:
derClassA(void);
derClassA();
...
}
};

derClassA::derClassA(void)
derClassA::derClassA()
{
}
...

Try to compile, I get "No appropriate default constructor".

Any thoughts?

Yes, post the real code.

dCA = new(derClassA);

dCA = new derClassA;

I suppose that could be the cause. Superfluous brackets are allowed in
many contexts in C++ but maybe not that one.

I'll check out your suggestion(s) and if I still can't get it I'll post
the real stuff.

And if you actually declared your class after main, that could be a problem
also. Declare them before main so the compiler knows what they are before
they're used.
