I have a problem compiling a module that I am porting form 2.4 to 2.6 linux kernel.

Compiling with this Makefile:
 
DEBUG = y
 
KERNELDIR = /usr/src/linix.2.6.9
SUBDIR = $(KERNELDIR)/drivers/snoop
INCLUDEDIR = $(KERNELDIR)/include
 
obj-m := snoop.o
 
modules: $(MAKE) -C $(KERNELDIR) SUBDIR=$(SUBDIR) modules
 
clean:
        rm -f *.o
        rm -f *.ko

apperars some lines like:
***Warning: "snoop_ip_forward" [drivers/snoop/snoop] is COMMON symbol
***Warning: "snoop_ip_forward_finish" [drivers/snoop/snoop] is COMMON symbol
 
and I have insert in ip_forward.c some lines:
 
    extern int (* snoop_ip_forward_finish) (struct sk_buff *);

and this is in function ip_forward():
       if(snoop_ip_forward && (*snoop_ip_forward)(skb) == -6)
                goto drop;
 
then when I try to install the module it repyes with:
    insmod: error inserting 'snoop.ko': -1 Invalid module format

and in /var/log/message appears some lines line:
    kernel: snoop: Unknown symbol __floatsidf
    kernel: snoop: Unknown symbol __fixunsdfsi
    kernel: snoop: Unknown symbol __adddf3
    kernel: snoop: Unknown symbol __muldf3

I will be very pleased if you can help me in some way.
thank you for your time

regards,
