Question

I’m creating a simple C++ header file in my xcode ios project but getting error “Redifinition of ‘foo’ as a different kind of symbol”.

Here’s the code

class foo 
{
    public:
         char* getLabel(char* params);
};

Well, the error message is pretty self-explanatory, foo is already defined in the same namespace, and you are trying to re-define it.

The part “as a different kind of symbol” suggests that the existing foo is something else rather than a class definition. Changing the name will most likely solve your issue. Another way would be to put your definition of foo into another namespace. And anyway I would not recommend you to name something as foo in a real project, no matter how small it is 😉
