You have the two classes (Siamese and Collie) dependant on each other which even if it works is poor practice. 2. Siamese has no functions defined. Elaine :rose: The tigress is here :-D

I know it's a circular dependancy, and I promise I'll do penance for that. But that wouldn't account for the compiler not finding Siamese in the Mammal::Cat namespace. And there is more to each class, but these are the lines that I've narrowed down as the most likely candidates for causing the problem. As far as I can tell, the namespaces are set up properly, and Visual Studio has no problem parsing them to generate the class view or to generate the drop-down list for the auto-complete feature, but the compiler won't compile it, claiming that the Siamese class is not a member of that namespace.

May be you could try forward declaration. like namespace Mammal { namespace Cat{ Class Siamese;} } then, the actual dog namespace then, the actual cat namespace. Sonork 100.41263:Anthony_Yio
