[omniORB] omniidl2 and crossed references ?

[David Riddoch]

Fabien,

The reason this is a problem is that you have IDL statements above an
include directive.  Currently omniidl2 just doesn't cope with that.

I suggest the following instead:

------------------

#ifndef CHICKEN
#define CHICKEN

interface Egg;

interface Chicken {
  Egg lay() ;
};

#endif

------------------

#ifndef EGG
#define EGG

interface Chicken;

interface Egg {
  Chicken hatch() ;
};

#endif

------------------


Hope this helps,
David
