Hi,
(Answer below)
the cpp file looks like so
#include "Comments.h"
using namespace DOM;
Comments::Comments()
{
}
the error i get is the Comments can't be used without a type. Then I
get told that it conflicts with a struct in AIFF.H (we include
Carbon.h into all of our files by default. (i am working on a carbon
project/Cocoa mixed project).
However if change my .cpp file to be....
DOM::Comments::Comments()
{
}
.. and add DOM:: to function declarations all is fine. Shouldn't the
compiler recognize i am in a new namespace or do i have to qualify
the declarations because of a global Comments?
That's not quite the way namespaces work. When you declare/define
something it has to be *in* the namespace either by:
Namespace::Class::Member(...)
or
namespace Namespace {
Class::Member(...) { ... }
}
using declarations are for *looking up* references in other
namespaces.
You can just write
namespace DOM {
Comments::Comments() ...
}
