Having problems to compile SPI

Hi.

I hope this is not a too much trivial question.

I'm having problems when compiling a new SPI function. I've been doing it
with :

gcc -I/usr/src/postgresql-6.3.2/src/include
-I/usr/src/postgresql-6.3.2/src/backend
-Wall -Wmissing-prototypes
-fpic -I/usr/src/postgresql-6.3.2/src/include
-c cascade.c -o cascade.o

but when I call de .o file from the function attached to the trigger , I
get the next message:

ERROR: Load of file /SAP/SQL/funcs/spi/cascade.o failed:
/SAP/SQL/funcs/spi/cascade.o: ELF file's phentsize not the
expected size

What can I do ???
