extension trouble

Hello,

Could you help me, please...

I'm trying to compile manually a simple extensions (the example given
on PHP site)
under OS-X 10.4 intel with gcc4.0


My commands are :
$ gcc -fPIC -DCOMPILE_DL=1 -I/usr/local/include -I../TSRM -I. -I..
-I../main -I../Zend -c -o test.o test.c
$ gcc -L/usr/local/lib -dynamiclib -o mylib.dylib ./test.o

and I get:
ld: Undefined symbols:
_zend_parse_parameters


I don't understand !


thanx

#include "php.h"

/* declaration of functions to be exported */
ZEND_FUNCTION(first_module);

/* compiled function list so Zend knows what's in this module */
zend_function_entry firstmod_functions[] =

ZEND_FE(first_module, NULL)
{NULL, NULL, NULL}
};

/* compiled module information */
zend_module_entry firstmod_module_entry =

/* implement function that is meant to be made available to PHP */
ZEND_FUNCTION(first_module)

return;
