Hi:
I want to cross compile netfilter(1.2.7a) to my arm-linux
platform(Kernel 2.4.17-rmk3).
I add these lines to the Makefile:
CC := /arm/bin/arm-linux-gcc #my arm gnu gcc
LD := /arm/bin/arm-linux-ld #my arm gnu linker
AR := /arm/bin/arm-linux-ar
Then compile the netfilter, some errors occur:
include/linux/netfilter_ipv4/ipt_conntrack.h:28: `IP_CT_DIR_MAX'
undeclared here (not in a function)
include/linux/netfilter_ipv4/ipt_conntrack.h:29: `IP_CT_DIR_MAX'
undeclared here (not in a function)

For this error, I check the netfilter code, and add two enum to
ipt_conntrack.h/libipt_conntrack.c, and then pass these errors.
But, in compile progress, still have some errors:
extensions/libipt_tos.c:58: warning: `struct ipt_tos_info'

extensions/libipt_tos.c:58: warning: its scope is only this definition
or declaration, which is probably not what you want.

Anybody tell me how can I pass this error? Many Thanks!
Best Regards!
