I'm trying to build some simple RPC examples from "UNIX IPC" by Stevens like 
listed below:

--- square.x---
struct square_in {              /* input (argument) */
  long  arg1;
};

struct square_out {             /* output (result) */
  long  res1;
};

program SQUARE_PROG {
    version SQUARE_VERS {
        square_out      SQUAREPROC(square_in) = 1; /* procedure number = 1 */
    } = 1;                              /* version number */
} = 0x31230000;                 /* program number */
--- square.x---

While building the client side seems to be fine but there's some problems with 
server:

---cut---

AFAIU the author tested his code primary on Solaris 2.6 platform so maybe 
there's some hints how to build RPC code on BSD ?
