warning when hiding methods

warning when hiding methods

[Philippe Haution]

Hello,

The program hereafter compiles silently with gcc3.2.3
and gcc 3.4.1 although there is a name hinding
problem.

Is there a compile option to get the same sort of
warning that Sun's CC would emit in this case :
"Warning: Son::func hides the virtual function
Mother::func(float)."
?

Regards,

PH

class Mother
{
  public:
    virtual void func(float b)
    {}
};

class Son : public Mother
{
  public:
    void func(int a, float b)
    {}
}; 

int main()
{
  return 0;
}
