I am not sure if this is the right place to post this. I have a simple
program that compiles on other compilers but not using qcc. If this is not
the correct place, please direct me to where it should go.
In my code I have a polymorphic method in the base class. In the sub class
I would like to overload one of the two methods and still have access to the
other in the base class. The below code is what I was using:
#include <stdio.h>
#include <stdlib.h>
class TestClass
{
public:
virtual void Hello()
{
printf(“Hello\n”);
};
virtual void Hello(int temp)
{
printf(“Hello with int\n”);
};
virtual void Hello1()
{
printf(“Hello1\n”);
};
};
class SubTestClass : public TestClass
{
public:
using TestClass::Hello;
void Hello(int temp)
{
printf(“SubClassHello\n”);
};
};
class SubSubTestClass : public SubTestClass
{
public:
using SubTestClass::Hello;
void Hello(int temp)
{
printf(“SubSubClassHello\n”);
};
};
int main(int argc, char *argv[])
{
TestClass *tc; // base class pointer
SubTestClass *sc = new SubTestClass(); // sub class
SubSubTestClass *ssc = new SubSubTestClass(); // subsub class
printf("\nFirstTest, Set *tc to Subclass and print\n");
tc = sc; // set base class pointer to sub class
tc->Hello();
tc->Hello(1);
sc->TestClass::Hello();
sc->Hello(1);
sc->Hello1();
printf("\nSecondTest, Set tc to ssc and print\n");
tc = ssc; // set base class pointer to subsub class
delete sc;
sc = ssc;
tc->Hello();
tc->Hello(1);
tc->Hello1();
sc->Hello();
sc->Hello(1);
sc->Hello1();
ssc->Hello();
ssc->Hello(1);
ssc->Hello1();
return(0);
}
When I try to compile it I get the following errors:

I believe that the code is correct. I have compiled it with other compilers
and it worked. Is this just not an implemented feature or is is a bug?
Thanks,

What other compilers have you used?
I see the same problem on Debian (gcc 2.95.4) and FreeBSD (gcc 2.95.3), but
not on my Redhat (gcc 2.96 → beta of 3.0), it looks like the problem is
happening with all gcc’s up to 2.95.x, and work fine with gcc 3.x.

Thanks,
Thanks for the response.
It worked with VC++ Version 6.0. It is interesting that it is working on
gcc 3.x. What would be the implications of using gcc 3.x on RTP? Also, do
you know any other way around having to re-declare all of the polymorphic
methods in a sub class if you just want to override one?
Thanks,
