I'll assume that you really want to build a kernel module, not a
userland application.  I'll also assume you have the source to the
target kernel installed on your development system.

In your Makefile for the module set you includes to point to the include
directory in your target kernel source (-I).  Below is a Makefile I used
a while back (2.4 kernel):

DRVSRC = arcom-0.41.c
DRVOBJ = arcom-0.41.o
CC = /opt/embedded/i486/i486-linux-gnu/bin/gcc

KERNELSRCDIR = /opt/embedded/kernel/linux-2.4.20-MZ

include $(KERNELSRCDIR)/.config

CFLAGS = -Wall -mcpu=i486 -fomit-frame-pointer -O3 -I. -I$(KERNELSRCDIR)/include -DMODULE -D__KERNEL__ -DLINUX -DDRIVER
#
# Uncomment the following to enable DEBUGging, PERFormance monitoring, or ADC SIMulation
#
#CFLAGS	+= -DSIM 
#CFLAGS	+= -DDEBUG
#CFLAGS	+= -DIDEBUG
#CFLAGS	+= -DPERF

ifdef CONFIG_PROC_FS
CFLAGS	+= -DWITHPROC
endif

ifdef CONFIG_MODVERSIONS
CFLAGS += -DCONFIG_MODVERSIONS
endif

arcom:	arcom.h
	  $(CC) $(CFLAGS) -c $(DRVSRC) -o $(DRVOBJ)

I did my development on RH9 and testing on an embedded system.
