Re: [Swarm-Support] Porting problems...

[Derek Farren]

Thanks Paul, I really appreciate it!!

I finally fixed it! But a new doubt arised in the process...

Why the header file can not find interface declaration for Discrete2d if
space.h is imported?? I had to explicity import space/dicrete2d.h .

Here is the line that calls for discrete2d:
@interface ConsumerDescription: Discrete2d {
  float minPrice, maxPrice;
}

Thanks again!
