[f2py] wrapping c with f2py

Stunned by the almost instantaneous response!

Yes, installing python-dev did make that example work.  So, my system 
appears to be able to handle the necessities now.  Thanks!

Now, perhaps you can please help me with this slightly more elaborate 
example:

// ------------  cadd.c ------------------- //

#include <stdio.h>
#include <stdlib.h>


int cadd(int a, int b){
   int c = a + b;
   printf("sum of %i and %i is %i\n", a, b, c );
   return c;
}

// -------------------------------------------- //

# -------------- padd.pyf -------------- #

python module padd
  interface
    function cadd(a, b, c) result c
      integer intent(c) cadd
      integer intent(c) a
      integer intent(c) b
      integer intent(c) c
    end function cadd
  end interface
end python module padd

# ----------------------------------------- #


I can compile with "f2py -c pyadd.pyf cadd.c" just fine.  BUT, when I 
try to import into python, I get:

> >>> import padd
> Traceback (most recent call last):
>   File "<stdin>", line 1, in <module>
> ImportError: ./padd.so: undefined symbol: unknown_function_

I've tried a couple of different formats for the PYF file, but I don't 
seem to have found the right approach.

Thanks much, Ariel
