PostgreSQL 8.1.5 Documentation - Chapter 32. Extending SQL

Hi,

I tried the code from "Calling Conventions Version 1 for C-Language
Functions"

I had to add this in order to make it compile:
/* 16-byte structure, passed by reference */
typedef struct
{
double x, y;
} Point;

Anyway, the "Point" is still giving me hard time:
psql:foo.sql:3: ERROR: could not load library "...foo.so": ld.so.1:
postgres: fatal: relocation error: file ...foo.so: symbol
PG_GETARG_POINT_P: referenced symbol not found

Thanks a lot,
Ray
