i have this problem with RPC (Remote Procedure Calls)

[gorett]

I can't tell where is the problem, i need this to be done and work. I have the source here and i ask for help.
I think that this program runs only on unix, i want to get this work on knoppix. Note that i am not so good on this.
avg.x

 * numbers and returns the average of their 
 * values. This toy service handles a maximum of 
 * 200 numbers.

  double input_data<200>;

        double AVERAGE(input_data) = 1;
    } = 1;

What errors does g++ give out when you try to compile it? Which lines are getting the errors? Nothing looks seriously wrong with your code.

It's also a good idea to put int in front of main(), because although int type is default on most compilers, it's much safer to manually specify it.

And please use code tags - more information in my signature. Thanks.
