I'm trying to bind to some C++ code, but when I compile the D side,
there are errors.  Here's my reduced test case:

// C++
namespace ns {
  void func1();
  void func2();
}

// D
module cpp;

extern(C++, ns) void func1();
extern(C++, ns) void func2()

dmd says:cpp_test.d(4): Error: namespace cpp.ns conflicts with namespace
cpp.ns at cpp_test.d(3)

What does this mean and how do I fix it?

Thanks!

Did you try this?

extern(C++, ns)
{
     void func1();
     void func2();
}

The compiler probably thinks you're trying to declare two 
separate namespaces. I'm not sure if this is intended or not.

Thanks for the response.  That does work.

Should I file a bug report or create a PR for the docs?

It might be a good idea to create a thread in DigitalMars.D to 
get clarification on the intended behaviour. A doc PR never hurts 
either.

i think it will be fine. and i think that this is more like a bug,
'cause it's ovbious that user wants the same namespace, not two
identically named ones.
