namespaces and forward declarations

[matthew polder]

Hi,

I have two libraries that used different namespaces, call them "fruit" and
"vegetable. " In one of the class definitions of fruit, I have the following.

class corn; //This doesn't work.

namespace fruit
{
class Apple
{
Apple( const vegetable::corn & )
{}
};

}

How do I do a forward declaration for something in a namespace?

thanks,
matthew

Have you tried?

namespace vegetable
{
class corn;
}
